What should we pay attention to in building swimming pools
The swimming pool:
First, the layout of the swimming pool. According to the nature of the swimming pool, the reasonable layout and shape should be chosen.
Second, the structure of the swimming pool. Reinforced concrete structure or detachable swimming pool can be selected.
Third, the choice of interior and exterior decoration of swimming pool. This is an important part of the quality of swimming pools.
Fourth, the entrance and exit design of swimming pool. Make it easy for swimmers to get in and out.
Fifth, choose good swimming pool water treatment equipment. Ensure clean and sanitary water quality.
The all building for swimming pools:
(1) Swimming pool buildings shall adopt the design concept of air conditioning zoning. Separate or window air conditioning can be installed in the office.
In order to save the electricity cost of air conditioning in the future.
(2) Frequency of ventilation: The swimming pool area should be ventilated 6-8 times per hour. The calculation of ventilation volume should refer to ASHRAE.
Standard 62 provides for the calculation of ventilation at 0.5 cfm/ft2 or 2.5 liter/S per m2, 15 cfm/per head or 8.0 liter/s per person in the swimming pool area (including the walkway around the pool, excluding the spectator area).
(3) The velocity of air supply in the swimming pool area should be less than 0.13 m/s at 2.4M above the pool to avoid it.
Excessive evaporation of pool water and cold feeling of human body.
(4) The pressure in the swimming pool should be slightly negative relative to the adjacent space, and the negative pressure should be kept between 12 and 37.
Pa or above, or make the exhaust volume of the swimming pool area greater than at least 10% of the air supply.
(5) Ventilation system in swimming pool area should be set up independently. It should not be used with ventilation system in other space to exhaust.
Parts must reach the roof before they can be discharged.
(6) Indoor air quality should be within 15 minutes. Concentration of carbon dioxide (CO2) should not be measured.
More than 1500 ppm (0.15%) and chlorine concentration should be below 1 ppm.
(7) The exterior wall glass should be designed with multi-layer glass. The interior and exterior walls of swimming pool area should be multi-layer glass, roof and roof.
Other places where dew may occur should be provided with dew-proof air supply. The air supply conditions should be sufficient to prevent fogging and dew from occurring in the swimming pool area. In principle, 20% of the air flow should be blown to the roof and 80% to the outer wall glass surface.
(8) Independent dehumidification, heating and heat recovery systems shall be installed in the air conditioning system of the swimming pool area, and the heat recovery system shall be installed in the air conditioning system of the swimming pool area.
The recovered heat source of air conditioning must be incorporated into the pool water heating system in addition to the reheat required by the dehumidification system itself, and the exhaust part must be sensible heat exchanged with the air to achieve energy-saving effect.
(9) Mechanical and electrical equipment that must be installed in the swimming pool area shall be set at a height and position that takes into account the convenience of future maintenance.
Benefits should not be set in the space directly above the pool surface to avoid affecting the maintenance of equipment.
