National code for design of indoor natatorium
2016-07-04 16:48
&The dehumidifier can not only be used indoors, but also be used in factories. In fact, swimming pools are equipped with multi-functional dehumidifiers. Now let’s take a look at the national building design code for indoor swimming pools.
&There are two parts: dehumidification system and constant temperature system.
&Double fan unit: as long as the supply and return fan is started, the dehumidification system and constant temperature system are also started. The dehumidification system detects the humidity of the return air, and the constant temperature system detects the temperature of the return air.
&Single fan unit: as long as the forced draft fan is started, the dehumidification system and constant temperature system are also started. The dehumidification system detects the humidity of the return air, and the constant temperature system detects the temperature of the return air.
&The indoor environment of natatorium is always in high temperature and humidity, so we should pay attention to the dewing phenomenon. According to the relevant standards and norms of sports buildings and swimming pools, the indoor air humidity of the swimming pool is constant at (60 ~ 70)%, and the air temperature is 2 ℃ higher than the water temperature, and the maximum is no more than 30 ℃.
&No matter what method is adopted in the treatment of swimming pool water, chlorine is contained. Therefore, it is necessary to control its concentration through ventilation and do a good job in anti-corrosion treatment.
&The fresh air volume shall not be less than 10% of the return air volume of the unit
&(2) the return air volume of dehumidification heat pump unit should be selected between 4 and 6 air changes
&(3) the fresh air volume (m3 / h) required by each person is 20 ~ 30 m3 / h;
&(4) the initial heating time of competitive and special swimming pools should be 24h-48h;
&(5) the initial filling time of competition and special swimming pools should not exceed 48 hours, while that of leisure swimming pools and water recreation pools should not exceed 72 hours.
