First of all, during the construction of the pool, it is necessary to take care of creating the proper microclimate, because from its surface there is a continuous evaporation of water, droplets of which settle on the ceiling and walls. High humidity not only creates a favorable environment for pathogens of fungi and mold, but also has a detrimental effect on electronic equipment, decoration and walls of the building. All these problems are solved by installing ventilation in the pool.
Ventilation options
There are many ventilation systems, but most often use two:
- supply;
- supply and exhaust.
Option I
This type is classified as separate, when the inflow and outflow of air is carried out by individual elements of the system. Equipment for such an installation is cheaper, although it will require significant expenses during operation, and its considerable size is not very suitable for small rooms.
A separate fresh air supply from the humidified outlet is a distinctive feature of the supply ventilation.
Installation of such systems is carried out even at the time of construction of the pool, when its main element, the fan, is installed in the exhaust ducts.
Fresh air inflow is realized with the help of such devices as:
- a control unit responsible for the temperature regime and maintaining the required volume of air;
- an air intake device with a valve that will prevent the flow of cold air into the room when the system is turned off;
- a fan for pumping it;
- filter for cleaning;
- device for warming the incoming air.
Option II
Such a system operates in a single unit. To acquire the necessary equipment will require significant costs, but during operation it is much more economical than the first option.
Main advantages:
- It does not require a lot of space for installation.
- Due to the presence of a recuperator, the energy consumption is negligible, since the incoming air warms up thanks to the exhaust gas, but at the same time does not connect to it. This saves up to 50% of electricity. Thanks to the heat reserve, we have a constant temperature in the room.
The design of such a system includes a number of important elements:
- supply air heater;
- recuperator;
- supply and exhaust fan;
- filter for cleaning;
- double valve that prevents the supply of cold air when the system is turned off.
Such ventilation systems can additionally be equipped with dehumidifiers and devices for distributing warm air to other rooms.
Pool Ventilation Project for a Private House
Gated pools in low-rise housing construction are becoming increasingly popular. Usually for its construction use the first floor. The preferred water surface area is from 18 to 50ӎ², and the depth is up to 2 m. Paths and recreation areas are placed around the perimeter. The main requirement for a private pool project is reliability and comfort.
A pool of this size is designed for 2-5 people. It can be used all year round or seasonally.
Fundamental rules
The recommended operating parameters for the private pool are:
- t water 26-29 ° C;
- air t 27-32 ° C;
- relative humidity in summer is 65%, and in winter - 50;
- air mobility of about 0.2 m / s.
To prevent stagnation of air in the room, the power of the exhaust equipment should be higher than the same parameter of the air handling units by half.
Design Features
The development of an individual project for the pool of a private house is carried out taking into account SNiP 2.08.02-89 SP and is carried out in the following order:
- Calculation of heat loss and moisture intake.
- The ventilation scheme and the drying device are selected.
- Estimated air exchange is calculated.
- The calculation of the length of the ducts, the placement of exhaust and flow chambers.
- Determine the pressure loss in all elements of the ventilation system and its throughput.
- Drawings are drawn up and specifications are drawn up.
After taking all these parameters into account, equipment of the required capacity is selected.
Carrying out the necessary calculations
To carry out the calculations, such data as the volume of the room and the liquid in the tank, the surface area where the contact of water and air occurs, the size of the bypass paths, temperature indicators and the number of visitors will be required.
Based on the difference between the product of the pool surface area and the vapor pressure in saturated air and the evaporation coefficient, air exchange is calculated. The value of the coefficient is taken from the tables, which take into account all indicators that affect the degree of operation of the room, and the number of procedures that increase air humidity.
Climate control and regulation
There are three methods by which you can control humidity:
- Condensation. When air flows through a dehumidifier.
- Moisture assimilation. This method purifies the air from persistent foreign odors.
- The most effective is the combined method, in which the dehumidifier and ventilation work independently or in concert, thereby maintaining an optimal microclimate.
Before choosing this or that method, you need to know the amount of moisture that the water surface will evaporate over a certain period of time.
How to create do-it-yourself ventilation in a private house with a pool
If you decide to install ventilation yourself, then you need to follow a number of rules:
- Hoods should be placed on the wall under the ceiling, as warm air moves from the bottom up.
- To ensure sufficient air speed it is better to use ventilation grilles of maximum area.
- The inflow is installed in the opposite part of the room from below.
Remember the main thing! Only ventilation designed in accordance with the rules will protect you from health problems and significant energy costs.
Tools and materials required for ventilation installation
- The ventilation device in the pool is carried out according to the same technology as the usual installation.
- Preference is given to ducts having a circular cross section.
- Stainless steel or plastic ducts on the exhaust line.
- The duct through which cold air is drawn must be insulated. Thermal insulation thickness not less than 50 ml.
It is recommended to install silencers, vibration mounts at the fan outputs, and use fans with speed controllers. Compliance with these rules and the use of noise insulation materials will make visiting the pool the most comfortable.
Description of the process of the ventilation unit for the pool
The ventilation of the pool is designed to eliminate excess moisture, supply fresh air, create comfortable conditions. Consider this process by the example of supply and exhaust ventilation. At the highest point of the room, wet and hot air is drawn, then it passes through the filter cleaning system. Here, chemical filters retain chlorine vapor.
After that, the collected air is supplemented with fresh in the required volume. This air mixture is driven through the radiators of the dehumidifier and heater, thereby bringing it to the required temperature and removing excess moisture. Then, the resulting air mass returns to the room.
Ventilation in a private pool is not an easy system, therefore it is better to entrust its arrangement to specialists.
