The room with the pool is very specific due to the presence of a large amount of water vapor. Moisture condenses on the surface with a lower temperature, resulting in corrosion processes, rotting and formation of fungus. In the room with a pool, windows are fought, moisture accumulates on subjects there. Eliminates all these inconvenience quality ventilation of the room with a swimming pool.
What is the ventilation of pools
Characteristics of water and indoor indoors are favored by the evaporation of water from the bowl, it is impossible to stop this process. Moisture settles on interior items and various design elements, which leads to them. A competently designed and mounted ventilation system will assign all air evaporation from the room.
The second negative factor from water vapor is discomfort located in the pool of people. Wet air negatively affects the respiratory organs and psychological state. The third factor is damaged by electrical equipment in the pool. Even covered with glass ceiling lamps are suffering.
Ventilation systems for better effect are equipped with air dryers. Among all the varieties of the ventilation system, the two most common are distinguished:
- Supply-exhaust with heat recovery
- With the separation of inflow and air outflow.
Continuing ventilation system with heat recovery
This type of exhaust system works in one block. At the stage of purchasing all the necessary materials, this system requires high expenses, but during operation more economical than flow ventilation. Advantages of use:
- Does not require a lot of location for installation. All components are located in one block, and therefore occupy a small area than ventilation with separated elements. It is optimally suitable for small pool areas and therefore used in private houses.
- During operation, the installation has reduced power consumption due to the presence of a recuperator. This device saves up to 50-70% of energy, since the trim air is heated due to the pulled gas, but does not mix with it. That is, the temperature in the room holds at the same level due to its own reserve of heat. Due to this, the required power of the motor used is reduced by 2-2.5 times.
The ventilation system of the supply and exhaust type contains such items:
- Cutting fan.
- Filter for cleaning incoming air.
- Double valve overlapping the passage of cold air while the system is turned off.
- Heat recuperator.
- Incoming air heater.
The supply and exhaust ventilation of the pool with heat recuperator in some cases is equipped with an automated controller indicators of water vapor and temperature. Also, in addition, install devices that distribute heated air to other rooms and air dryer.
Ventilation with separation of inflow and air outflow
This system is separate, input and air output is made by different system elements of ventilation. Equipment in this case is cheaper than for the first type of ventilation, but during operation it will require large expenses. Also, separate ventilation has rather large dimensions and is not as convenient for use in small rooms.
The flow ventilation of the pool is characterized by a separate supply of fresh air into the room with a simultaneous removal of an already moisturizing air outward. The equipment of this type of ventilation takes place at the stage of common construction work on the construction of the basin. The main element is the fan built into the exhaust channels. Air flow is carried out using the following equipment:
- The air taking the air equipped with a valve that does not pass into the room the cold stream during the system shutdown.
- Purifying air filter.
- Heater of incoming air.
- Fan for air injection.
- Control unit to maintain the temperature level and the volume of incoming air.
Automation of ventilation
The automated system performs complete control over the ventilation system, adjusts its functions. The work that automated system performs:
- Holds the humidity and temperature of the air at a given level, as well as the performance of the ventilation system itself.
- At the given time intervals, it includes or disconnects the individual structural elements of the system or its entire in general.
- Notifies the emerging situations and problems of the system.
- Tracks the sequence of all operations passing in the system.
- Provides protection of the system as a whole and its separate components, protects water calorifers from freezing moisture into them, voltage drops, etc.
- Communicates ventilation with the Smart Home system.
Air Parameter Norms in the Pool
The ventilation system is selected under certain indicators that are respected in a room with a swimming pool. When creating safe and pleasant conditions in the room, the following numbers are withstand:
- Air humidity not more than 65%.
- The temperature ratio of air and water does not exceed 2 ° C in favor of air.
- The temperature indicator of water is held to the 32 ° C.
- A gas flow out of ventilation does not exceed 0.2 m / s, since higher values \u200b\u200bcreate tangible leather drafts.
- The normalized value of the air exchange is 80 m3 / h per person located in the premises. But during the design, it is allowed to use this number, but the calculated value.
The norms allow the difference in the number of incoming and outgoing air in the size of half the multiplicity of the air exchange pool. Here, however, the gas flow rate is taken into account. When calculating the project also take into account the number of noise decibels in the room, its maximum threshold is 60 dB. Natural ventilation does not create parameters described in the basin, because the room is mandatory to equip the mechanized ventilation system.
Nuances Development of the Ventilation Project
When creating a project of a ventilating structure of any type, the functional characteristics of the design itself are taken into account, to provide the defined conditions, and negative factors affecting structural structural elements. One of the very first harmful substances is condensate. Its cluster on the surface of the ventilation shaft will cause corrosion and damage to the equipment. To avoid this, the mine isolate or apply valves with electrical heating. Also, the ventilation shaft is complemented by a tray for a collection of gathering moisture.
In the basin ventilation system of any type and size, it is necessary to provide for the possibility of working in less productivity to save energy during the downtime of the pool. Accordingly, it is necessary for the equipment with an enhanced power device so that the ventilation effectively copes with its functions when there are many people in the pool. These supplements are not required, but help to save electricity with round-the-clock operation, while the efficiency of the system will not fall. This is a particularly relevant addition for private houses in which the equipment is used much less frequently than in public pools.
The most important rule when calculating the project is to account for the area of \u200b\u200bthe room, the calculation of the values \u200b\u200bof the multiplicity of air exchange and air flow, the presence of the heating function of the room. The supplied and exhaust ventilation of the pool is multifunctional and solves all the tasks. It has various structural elements - the filtering system, calorifer and fan. This causes the fulfillment of all these functions. Basin ventilation is mounted separately from the main house system. Reduce the evaporation of water from the pool by resetting it for idle period.
How to develop a basin ventilation project
As mentioned above, when the basin ventilation is designed, the calculation is carried out taking into account air humidity of 65%, but this value in practice is often reduced by 15-20%. This is due to the tactile feeling of high humidity. If the ventilation system is equipped correctly and provides the necessary indicator of humidity, the condensate and discomfort is noticed. As a result, the functional characteristics of the ventilation change, while the described phenomena disappear, but the humidity indicator does not correspond to the stated standards.
When calculating the project, air flow rate is taken into account. Special formulas and tables help determine the necessary air exchange with a temperature indicator and the area of \u200b\u200bthe water space of the pool.
All indicators that take into account when calculating:
- The total size of water space.
- The size of all bypass tracks.
- The size of the room.
- The average temperature index outside the room in the winter and summer period.
- Water temperature.
- Air temperature in the room itself.
- The average number of visitors to the pool.
- Taking into account the fact that the flow of warm air is striving up due to the smaller mass, it is necessary to take into account the temperature indicator under the ceiling.
With independent calculation of the ventilation project for the pool, such calculations also conduct:
- Given the flow of heat from bathing people, external solar exposure, bypass tracks, lighting, from the water itself.
- The flow of moisture from bathing people, water surface, from bypass tracks.
- The air exchange is calculated by moisture and total heat, the regulatory air exchange is taken into account.
According to the standard of society of German engineers, the air exchange is calculated depending on the area of \u200b\u200bwater stroit, its temperature indicator, total humidity
air and functional features of the pool. For calculations, the formula is used:
W \u003d EXFXPB-PL, kg / h. Here:
- F - the overall size of the water surface of the pool, m2.
- PB - water vapor pressure indicator in saturated air, taking into account the temperature indicator of water in the pool, bar.
- PL - water vapor pressure indicator at a given temperature mode and humidity, bar.
To enter the pressure indicator in the kPa, they take into account that 1 bar \u003d 98.1 kPa.
e In this formula, the evaporation ratio, kg (m2 * hour * bar), determines the functional features of the pool. For different types of pools, it is equal to:
- Cover Water Water Covered - 0.5.
- Fixed water smooth - 5.
- The design of small sizes with a small number of visitors is 15.
- The design of public use with an average indicator of the activity of swimmers - 20.
- Design for places of active entertainment and recreation - 28.
- Design equipped with water slides and with the formation of waves - 35
In the calculations, focus on the selection of moisture during the use of the pool, this creates a margin of the strength of the entire system. To calculate air exchange in the pool, the formula is used: ML \u003d GWXB-XN, kg / h, is a formula for calculating the mass flow. Volumetric flow is determined by the formula: L \u003d GWRXXB-XN, kg / h. Here:
- L - Consumption of incoming air volumetric, m3 / h.
- mL - Consumption of incoming air mass, kg / h.
- GW - the volume of all evaporation moisture indoors, g / h.
- XN - moisture content outside the room, g / kg.
- XB - moisture content indoors, g / kg.
- r is an air density indicator at temperature mode indoors, kg / m3.
The index of moisture content outside the room has a tendency to change with a change in the time of the year. This change in winter reaches 2-3 g / kg, in summer - 11-12 g / kg. Practitioners specialists are focused on an indicator of 9 g / kg, because the seasonal change of this indicator is not long. As for the XB value, it is accepted a little more calculated, since in the summer season the number of emerging condensate is insignificant.
In the process of installing ventilation, all air ducts are carefully sealing and heat insulated. The air flow is not directed to the surface of the water. A small ventilation system is installed between capital and suspended ceiling. If the ventilating system is installed in the room, the use of the air conditioner in it is not recommended.
The favorable atmosphere of the home pool is achieved not only by heating, water heated, but also with high-quality ventilation. It is necessary for creating the necessary humidity and temperature regime in the room, the premises of the formation of mold, fungi, causing severe infectious diseases, conservation of finishing, comfortable pastime.
Types of used ventilation
As a rule, home pools are located on the first floor of the structure, have a small area of \u200b\u200bthe water mirror. Less likely in basement or basement floors.Without installing special equipment in rooms with a swimming pool, it is not realistic to keep a comfortable and safe microclimate. The mechanisms and aggregates used should ensure the exchange of air masses, which does not create a threat to human health both by air humidity and in the temperature regime.
To solve a whole complex for maintaining the desired microclimate in a room with a domestic pool, absorb excessive moisture penetration into other parts of a residential building or cottage use 3 vents of ventilation systems.
Forced
Natural ventilation for rooms with high humidity does not apply through its ineffectiveness. The most frequently used option is forced supply and exhaust ventilation, characterized by its sufficient productivity and the ability to use various additional equipment.The main task of this version of the ventilation is to guarantee the maximum aeration. With a working system, air masses are directed along the walls to the ceiling, providing air circulation with a minimum speed above the aqueous mirror of the pool and around the perimeter of the entire room. This contributes:
- the absence of moisture condensate on the ceiling and walls;
- reduce evaporation from the surface of the pool;
- enhance comfort bathing.
In addition to bringing the state of air moisture condition, the supply and exhaust ventilation removes unpleasant smells of damp, giving it a feeling of freshness. Installing additional automation allows the regulation of the ventilation process in relation to the pool operation mode.
The disadvantages of this vents include the work of the entire system in the summer period of the year, when it is not always possible to achieve regulatory indicators on the humidity of the room.
Supply-exhaust with additional air drainage
Devices reduction of suspended moisture in the air without appropriate ventilation do not give the expected effect. Only in sharing it is possible to achieve the required indicators of air humidity - the main criterion of the closed home pool.Air dryers for the pool can be:
- wall-mounted indoor pool;
- cassette or channels installed in utility rooms.
Experts recommend to apply both options for air drying at the same time, which gives a good positive effect. The relatively low cost at high efficiency is the main advantages of dryers. But as often happens, the system does not always cope with the "duties" in hot summer weather.
Combination of ventilation, drainage and air conditioning
The most efficient method of the specified combination to maintain the specified humidity parameters and temperature regime in the pool. Supply-exhaust ventilation functions in normal mode. Peak loads include dryers and air conditioners.Climatic aggregates consisting of ventilation, drying systems and air conditioning devices are included and adjustable by automation, which selects the installed humidity parameters and, if necessary, includes a particular system. In the cold season, the humidity regulates the air dryer, and the air exchange is ventilation.
The presented video clarified the need for a ventilation device with a pool, and why it is impossible to achieve high-quality ventilation by simply opening windows:
Ventilation options in the pool
A professionally designed and mounted ventilation system in the private house must completely remove all evaporation of water, maintain a comfortable indoor microclimate.The supply and exhaust ventilation system in the pool is 2 types:
1. With heat recovery.
The entire system is manufactured in one block, which takes a little space and more economical during operation. Thanks to the recuperative block, electricity savings are up to 75%, since the trim air is heated due to the removable without mixing with it. This contributes to maintaining the temperature regime in the pool due to its own heat. The power of used energy installations is reduced by 2 times in comparison with the use of separate ventilation.
Such systems are equipped with the following mandatory equipment:
- air purification filter;
- heat recuperator;
- incoming air heater;
- supply fan;
- the system of 2 valves, overlapping cold air access when the system is turned off.
2. With the separation of supply and removed air masses.
The discharge of fresh and removal of the exhaust air is made by individual energy systems in their air ducts. Such systems are more large-sized, require increased operational costs. In the home pool in the absence of a special room for its installation, this ventilation system is not used rationally due to dimensions.
Both directions work synchronously: one injected atmospheric air, the second removes the channel-spent on the channel, equipped during the period of the overall work. On the feed side are mounted:
- filter for cleaning the incoming air;
- heater of atmospheric purified air;
- suction fan;
- the control unit for the volume of intake air and its temperature regime during the heating period.
Drying air
In domestic pools, desiccants are often installed, where it is impossible to install a bulky system of inflows. The air, falling into the installation, heats up and returns to the pool, moisture - condenses and removed.Types of dryers used in pools are divided into 3 groups:
- Wall-mounted open type. Installed on the wall after the completion of the finishing works in the indoor pool.
- Wall-mounted hidden type. Mounted in the next room. The pool is connected through the space provided by the opening in the wall.
- Stationary. To install this type of equipment, a separate room adjacent to the pool is necessary. Possess increased power. Used in system-exhaust and combined ventilation systems.
The last 2 species are envisaged only during the execution of design work.
The video presented shows examples of the use of air dryers for pools, the principle of their work, the need to install:
Combined systems
Combined aggregates perform several functions, have a rather bulky equipment mounted in a separate room. Such equipment is called climatic, as it supports the optimal operation mode in a closed home pool, regardless of weather conditions.Applicable equipment in combination ventilation:
- patch and exhaust fans;
- recuperator;
- air Dryer;
- air filtration system;
- air heating equipment;
- valve system;
- automatic control unit.
Features of installation work
Development of the design solution of the ventilation device in the room with a pool is performed by qualified engineers, taking into account all the necessary parameters. At this stage, not only the most effective version of ventilation is calculated, but also substantiates its economic feasibility.The basin ventilation system is better to perform entirely independent of the ventilation of the entire individual house or cottage.
Works on the ventilation device are beginning to be carried out during the fulfillment of general construction work: suite channels, plotters. Ventilation shafts are performed under the ceiling of the room, followed by facing with finishing materials.
Air ducts are mounted from plastic or metal profile pipes made of galvanized sheet metal. The latter option is used in the case of using air ducts for heating the room.
The diagram of the air ducts is mounted so that the possibility of adjusting the direction of the air flow throughout the room is uniformly.
The power supply is not desired indoors with high humidity, better - in an isolated room. In the absence of such - you can use the space of the attic overlap.
The pipeline system must have free access for annual preventive measures - air duct cleaning.
The reliability and high-quality productivity of the basin ventilation system is laid at the work project development phase, which must take into account all the nuances of future operation. According to the laws of physics, warm air masses rise up, condensate is formed on cold surfaces.Equipment can be installed in the adjacent room, under the bowl of the reservoir, on the wall. The supply channels are more often placed around the perimeter of the room, to quickly remove wet air upwards, where exhaust ducts are located. It must be considered:
- compliance with the volume of incoming and removed air contributes to the absence of drafts;
- special types of lattices reduce the intensity of the movement of air masses without disturbing the speed of air exchange indoors, which is important for the hosting sites;
- in the presence of windows in the room, the air supply must be carried out under the windows, proactive the formation of condensate on the glasses;
- exhaust ducts are always mounted above the intuitions, better under the ceiling, providing high-quality removal of wet air;
- the space between the suspended ceiling and capital should be ventilated to preete the formation of colonies of mold and fungi;
- the flow of injected air should not pass over the aqueous mirror, because it reduces evaporation from its surface;
- the system must have 2 airflow controls: automatic and manual.
The temperature of the atmospheric air affects the total energy consumption for its heating and the performance of the equipment. Applying automatic adjustment of the temperature regime, it is possible to significantly improve the rational use of electrical energy.
Designing, installation of the ventilation system is better to carry out to perform the specialists of the corresponding profile. This will save money not only, but also during operation.
Safety criteria
As in the performance of all construction and installation works, when the air exchange system is configured in an individual residential building or cottage, you must follow specific rules:- Each employee must have personal protective equipment, special shoes and clothing.
- Workplaces of production of a specific type of work should be fenced, proactifying people unused in the installation of people into the working area.
- The working area should be covered.
- Under the mounted air ducts at the height should not be extraneous workers.
- Welding works are performed by workers with appropriate qualifications.
- After the operating cycle is completed, the power tool must be disconnected and de-energized.
- Work on the installation of equipment at the height is prohibited to carry out without consolidation and additional insurance of the stepladder, lumps.
- Performing outdoor high-altitude work in ice and rain is prohibited.
- All mounting works of the air duct system must be performed in pairs.
The neglect of the ventilation systems in the pools consistently leads to increased humidity, the appearance of fungus and creating an unfavorable microclimate for health. The accumulation of condensate damages the finish and destroys the structural elements of the building.
Agree, the prospect of premature major overhaul will make few people. Preventing negative impact of high humidity will help well-thought-out ventilation basin - the system provides air exchange within sanitary and hygienic standards.
The issue of ventilating organization must be solved at the design stage of the premises. In the article, we considered typical schemes for arranging the enclosed basins of the closed basin, described effective ways to control humidity, led recommendations for the development of the project and the choice of climatic equipment.
During the construction of swimming pools of public and private purpose, sometimes they do not pay due attention to the ventilation halls, considering their non-residential premises.
However, it is there without proper arrangement that malicious fauna and flora are born, carrying a real threat to almost unprotected organisms of swimsters and swimmers.

Many buildings that are currently being built, both industrial and residential, have a very difficult infrastructure and are designed with the maximum focus on energy saving. Therefore, uninstallations of such systems, as systems of general air ventilation, smoke-protection systems and air conditioning systems, it is impossible to do. To ensure an efficient and long service of ventilation systems, it is necessary to qualitatively designate and establish a system of communicating air ventilation, smoke-protecting system and air conditioning system. Installation of such equipment of any type should be made with the mandatory observance of certain rules. And according to technical specifications, it must correspond to the volume and type of room in which (residential building, public, industrial) will be operated.
Of great importance is the correct operation of ventilation systems: compliance with the timing and rules for conducting preventive inspections, planned-warning repairs, as well as the correct utensilization of ventilation equipment.
On each ventilation system, the passport and operational log is drawn up. The passport is drawn up in two copies, one of which is kept in the enterprise, and the other in the technical supervision service. All technical characteristics of the system are entered into the passport, information about the repair work, copies of the executive drawings of the ventilation equipment are attached to it. In addition, the passport reflects the list of operating conditions of all nodes and parts of the ventilation systems.
According to the established schedule, planned inspections of the ventilation systems are carried out. During scheduled inspections:
- Defects are detected, which are eliminated at the current repairs;
- The technical condition of the ventilation systems is determined;
- Partial cleaning and lubrication of individual nodes and parts are carried out.
All data of the planned inspection of ventilation systems is mandatory indicated in the operation log.
Also, during the work shift, on duty operational brigade, it is envisaged by the planned interrelation of ventilation systems. This service includes:
- Start, regulation and turning off the ventilation equipment;
- Supervision of the operation of ventilation systems;
- Monitoring the compliance of the parameters of the air and the temperature of the supply air;
- Elimination of small defects.
Commissioning works of systems of universal ventilation of air, smoke-protection systems and air conditioning systems
Stage of commissioning works is a very important stage, because the quality work of ventilation and air conditioning depends on commissioning.
When commissioning, you can see the operation of the assembly command, and the parameters specified in the project occur checking and comparing the equipment indicators with the indicators specified in the project documentation. During the survey, a complete verification of the technical condition of the mounted equipment, the distribution and smoothness of the adjustment devices, the installation of control and diagnostic devices, detecting errors during the operation of the equipment is carried out. If deviations are detected, which within the normal range, then the calm does not occur, and the object is prepared for the delivery to the customer, with the design of all documents.
All masters of our company have a specialized education, certificates for from and TB, rich work experience and have all the necessary documents and evidence.
At the stage of commissioning work, we measure the air flow rate in ducts, noise level, approbation of equipment installation, adjusting engineering systems in accordance with the project parameters, certification.
Starting tests and adjustment of ventilation and air conditioning systems must be carried out by a construction and installation or specialized commissioning organization.
Passportization of ventilation systems
The technical document, compiled on the basis of checking the working condition of the ventilation systems and equipment carried out by means of aerodynamic tests, is called the passportization of the ventilation system.
SP 73.13330.2012 "Internal sanitary and technical systems of buildings", the updated edition of SNiP 3.05.01-85 "Domestic sanitary and technical systems" regulate the form and content of the passport of the ventilation system.
Obtaining a passport of the ventilation system, in accordance with the requirements, the above documents, is mandatory.
At the end of work on the installation of ventilation systems, the customer receives a passport of the ventilation system.
Passport must be obtained for each ventilation system.
The passport is indispensable to register purchased equipment, for proper operation, such equipment, in order to achieve the necessary sanitary and hygienic air parameters.
In the period established by the legislation, this document is provided by the supervisory authority. Obtaining this document is undeniable evidence in solving controversial issues with relevant instances.
Obtaining a passport of the ventilation system can be carried out as a separate type of work consisting of a complex of aerodynamic tests. Conducting such events is regulated by the following regulatory acts:
- SP 73.13330.2012;
- One hundred nostroy 2.24.2-2011;
- R nostroy 2.15.3-2011;
- GOST 12.3.018-79. "Ventilation systems. Aerodynamic Test Methods ";
- GOST R 53300-2009;
- SP 4425-87. »Sanitary and hygienic control of ventilation systems of industrial premises";
- Sanpin 2.1.3.2630-10.
With an extensive area of \u200b\u200bthe water mirror of the pool, water is constantly evaporated, the droplets are settled on the ceiling, windows and walls. In such a wet and warm environment, the causative agents of mold and fungi feel perfectly. What you can not tell about the visitors of the pool. Significant harm is applied and elements of the design. Condensate does not just look unattractive, gradually it destroys the finishing materials.
Increased air humidity in the room leads to the following consequences:
- metal structures are covered with rust;
- the fungus develops;
- the plastered surfaces swell and destroy;
- the painted parts fasten are covered with spots;
- the conductivity of insulating materials increases, the probability of shock beats appears.
That is why ventilating installations are required. If we are talking about water parks or indoor sports basins, additional air drainage is usually required.
Air humidity is one of the most important indicators that determine the quality of ventilation. Humidity is the amount of water vapor per unit of air volume. With high humidity, people breathe hard. But too dry air in the pool is also minus. Intensively evaporated, the water cools the body of swimmers, causing discomfort.
When designing the ventilation of the pool into account, it takes the mode of its operation, climatic conditions of terrain and wishes of the customer. The player's ventilation feature is that the temperature and air temperature has a significant effect on the calculated parameters.
Microclimate pool room
The maximum amount of water that air can take at a certain temperature is called humidity saturation. An increase in air temperature entails and increasing the level of this indicator. The level of moisture in the air is determined by mass in grams divided by 1 kg of air. If the maturity threshold is passed, the excess is settled on the walls, glasses, the ceiling.
Before doing ventilation in the pool, the evaporation of moisture should be reduced, for which a certain combination of water and air temperature is achieved.
The air temperature is 1 to 2 degrees above the water temperature.
Moisture evaporates the minimum amount, which means that the basin ventilation equipment is needed less powerful. With equal indicators of air and water temperature, saturation point is achieved with air humidity of 100%.
But that people in the pool premises feel comfortable, humidity should be from 50 to 65%. It is possible to achieve such an indicator only by means of a mechanical ventilation unit for the pool.
Evaporation slightly decreases if the water surface is covered with special blinds. The covered water almost does not evaporate and is not cooled due to evaporation.
For comparison:
- with an open water mirror, 2.3 liters are evaporated for an hour;
- with closed - 1.2 liters per hour.
That is, resource saving is ensured during the operation of the basin.
Ways to reduce humidity in the pool room
It is impossible to completely prevent the evaporation of moisture in the pool. But it is quite realistic to reduce it, installing the dryer, the suppress and exhaust ventilation or combining both methods.
Reducing air humidity can be carried out by two methods:
- condensation;
- assimilation.
Condensation of moisture in the pool
Air is driven through the desiccant where its temperature reaches the dew point. The moisture condenses, after which the air heats up to the desired temperature and returns to the room.
Such installations are good for ventilation of the pool in the cottage, where it is impossible to implement the inflow system-blowing. The design is equipped with a hygrostat, which starts the compressor when the humidity is achieved certain indications. As soon as the humidity goes, the hygrostat stops the operation of the compressor. The fan can continue to rotate.
Condensation dryers are:
- Wednesnas, which are hung on the walls. They can be installed indoors with finished finish;
- Nastya hidden. All equipment is hidden in the adjacent room, only a fence lattice is released into the pool. Planning such a basin ventilation system in a private house is necessary at the construction stage;
- Stationary. These are powerful installations that require special premises. They can be included in the supply and exhaust ventilation system for the basin of the sports complex. The stationary desiccant admits the submersion 1 \\ 5 of the air volume. The inflow and blowing air are provided by the air channel system. Equipping the system with a channel heater, we get full ventilation.
Moisture assimilation in the pool
Under this principle, the supply and exhaust systems work, using the air property, gain water pairs. With approximate calculations, 5-fold air exchange per hour is laid.
Often in moderate latitudes to maintain the necessary microclimate in the room of a small private pool just ventilation. But when calculating the ventilation of the swimming pools of sports or entertainment complexes without a desiccant can not do. Especially if they are located in places with a hot climate.
The assimilation method is good in that the air is cleared of unpleasant odors. The most significant drawback is the dependence on the weather. If the humidity of atmospheric air is large, it does not absorb moisture, hitting the pool room. However, in many cases, this scheme is applied in practice.
The second significant drawback is the trim air must be heated. This is especially noticeable in the cold season, when electricity is spent on heating.
Combined Basin Decisions Method
The optimal view of the installation of drainage and ventilation for the intensive visits pools and a large area. Specialists recommend using both desiccant and forced ventilation. Systems can be independent, in no way connected or compile a general system for maintaining a microclimate.
This is expensive equipment, justifying itself only in pools with an area of \u200b\u200bat least 50 square meters. meters.
Methods for maintaining air temperature and removal odors in the pool
The air temperature in the pool room must be maintained above atmospheric. For this, the heating system is mounted. Air coming from the supply channels is heated to a temperature supported by the heating system. However, ventilation equipment is not intended for the heating of the room.
Air heating in this case does not justify itself, since the intensive movement of air accelerates the evaporation of water. It can only be used as an additional if the main heating does not cope.
If the room is plentifully glazed, the pool is located in the southern region, the air conditioning is additionally provided.
In the naturally visited large basins, natural ventilation is powerless, therefore, forced methods of air movement are applied. They provide a stable temperature, fresh air supply, elimination of unpleasant odors and comfort for visitors.
The most effective method of providing the best conditions in the pool is the installation of the supply and exhaust ventilation.
Advantages of the sub-exhaust system:
- the influx of fresh air is ensured;
- excess moisture is removed from the atmosphere of the pool room.
The system is equipped with a drier of air, and excess heat is removed to the street. It is autonomous and is not connected with the air exchange of the rest of the building. Ventkanals are created from moisture resistant materials. The equipment is controlled by automatic supporting a constant temperature and underwear.
Air from the street before serving the room, filtering, cooling or heating, changes and its humidity varies depending on the specified parameters.
Microclimate parameters for swimming pool:
- water temperature +26 - 31 degrees;
- air temperature +27 - 32 degrees;
- humidity from 50 to 65%;
- air exchange per 1 visitor 80 cubic meters per hour;
- air movement speed up to 0.2 meters per second;
- the concentration of chlorine molecules to 0.1 milligrams per cubic meter of air.
Water temperature in saunas pools:
- hot +35 degrees;
- cold +15 degrees.
The possibility of heat recovery in the pool
The ventilation system of the pool in the cottage or water park with heat recovery will save significant means on heating the air supplied. The heat recuperator uses heat from the exhaust air for heating fresh. The heat utilizer can have a lamellar design, rotary or work on the principle of the heat pump.
Recovery in summer allows you to cool the air supplied inside. On average, the savings are about 70% for the year. The installation is equipped with filters and calorifer, which, if necessary, brings the temperature of the air to the desired (for example, in winter).
Pool Ventilation Rules
The design of the swimming pool ventilation is a rather complicated process that takes into account the many nuances. Competently plan the ventilation of the pool with your own hands only at a specialist.
When calculating ventilation, the pool should be considered:
- wet and heated air masses rush to the ceiling;
- condensate is deposited on all cool surfaces.
You can install equipment for ventilation of any pool in the adjacent room and under the bowl itself, around it, top or on the wall. Often, the supply grids are placed around the pool or from two sides, contributing to the speedy outstanding of the spent wet air up to the exhaust.
An important component in the operation of the supplied and exhaust ventilation of the pool is the outer air. Its temperature affects the performance and power consumption of the system. In the frost, the air is cold and dry, in the heat - wet and warm. Thus, the ability to regulate the exchange of air allows you to create a comfortable microclimate without spending unnecessary resources.
Adjustment with fans, increasing or reducing the intensity of the blowing and the volume of mobile air masses. Used manual or automatic control method.
Another important in the calculations of the pool ventilation parameter is the temperature of the supply air. It is heated by electrothenes before serving into the room, and competently counted temperature saves on the heating of the hall.
Features of the design of ventilation pools in cottages
When designing the ventilation of the private house, the following features are taken into account:
- the temperature of the water in the pool for domestic standards is +30 - 32 degrees, according to Eurostandards +28;
- the air temperature according to European standards exceeds the temperature of water by 2-4 degrees, according to domestic per 1 to 2 degrees;
- air outflow may prevail over the influx of 0.5 times;
- the noise level from the working installations should not exceed 60 decibels;
- in the pool bathes, as a rule, no more than 2 people at the same time;
- using an episodic pool, not long;
- blinds and curtains for water mirrors are widely used.
Supply-exhaust installations are used as the basin ventilation equipment, you can separate, but always autonomous from the main system of ducts at home.
When placing supply grids around the pool, discomfort from moving the air masses is created, which is understandable, given the small area of \u200b\u200bthe room.
It is advisable to use dual-mode installations: the influx is started separately from the exhaust. When the pool is not used, it is enough to ensure the outflow of wet air out of the room.
Many customers require imperceptible ventilation in the pool, which does not violate the design and architecture.
Choosing equipment and automation of the relatives of the pool
Selection of schemes and equipment for basin ventilation in the cottage is based on thorough calculations. Any factors change the speed of evaporation are taken into account:
- pool area;
- water and indoor water temperature;
- calculated humidity indicators;
- visiting mode;
- number of visitors;
- the presence of water coating;
- the volume of the hall in which the pool is located.
For the calculations of basins ventilation, data on the average humidity and temperature in the cold and warm season are also required.
Automated control system allows, once setting the necessary parameters, no longer remember the basin ventilation of its private home. Electronics itself will determine the volume of the inflow, outflow in the event of a change in temperature or humidity.
Automation systems capabilities:
- start or disabling ventilation (at a certain time or depending on air characteristics);
- control over humidity and air temperature;
- protection of equipment from drops in the power grid;
- alert of violations in the work of the equipment;
- integration into the Smart Home system.
Air conditioners for pools
Beautifully decorate a thin taste pool
This is the embodiment of the latest technologies that make your own hands to purchase equipment for basin ventilation. Air conditioners for pools Create the desired microclimate, fully automated and operate in the following modes:
- Heating of premises. The built-in thermal register allows you to warm up the air in the hall where the pool is located;
- Drainage of air. The process passes in a heat pump, where the air temperature drops to the dew point and the moisture drops are deposited on the walls of the evaporator flowing into the capacitance to collect condensate. Then the air falls on the heat exchanger and heated before serving to the room;
- Submers of fresh air. This feature allows air conditioner to completely replace the pool ventilation scheme, feeding heated and filtered air into the room. Heating occurs due to heat recovery from the removed air;
- Summer mode. If the temperature of the atmospheric air exceeds the temperature indoor, this mode is started;
- Enhanced drainage. This mode is included in the private pool ventilation scheme at will. It is necessary in areas with high atmospheric humidity.
Air conditioning allows you to make ventilation in the pool simple in control and installation. For a country house, this is the perfect option. But there are more powerful models for therapeutic or public pools. Used technologies allow you to minimize the costs during operation. The power of the fans, as well as the operation of all other nodes, is controlled by an electronic switch.
The air conditioner unit is protected from corrosion by polymeric material and is insulated.
Control is carried out with a remote control, as well as an additional remote control. The screen reflects information about the temperature and humidity of the room. Many models are equipped with modems allowing to manage remotely.
Such systems allow you to very accurately support the microclimate in the room, providing high-quality ventilation of the pool. With your own hands, the owner can choose suitable equipment.
