There is a hotel with a swimming pool in Changsha. Now we are going to do constant temperature dehumidification. How should we choose equipment?

In order to ensure the comfort of people after entering the water and before entering the water, according to the international swimming pool design standards, the air temperature in the swimming pool hall should be higher than the water temperature 1 ~ 2℃, the relative humidity is generally 50 ~ 70%, but not more than 75%, and the wind speed should be controlled at about 0.2m/s. At the same time, in order to prevent dew condensation on the enclosure structure in winter, the international swimming pool design standards stipulate that the air moisture content in the billiard hall should not be greater than/kl. Because air humidity is also closely related to human comfort. Low relative humidity, dry air and low partial pressure of water vapor in the air will accelerate the evaporation of moisture on the moist skin surface that has just come out of the water, take away the latent heat of evaporation of the human body, and easily make people feel cold. At the same time, more water evaporates, and the moisture content of indoor air increases, which increases the ventilation required to eliminate indoor residual humidity, and correspondingly increases the load of heating and sending indoor fresh air in winter. If the relative humidity is too high and the indoor air moisture content is too high, the dew point of the air will increase, which will cause dew condensation on the inner surface of the enclosure structure, which will affect the whole building structure in serious cases, so it is necessary to keep the swimming pool at constant temperature and dehumidify.

Water source: the amount of water lost by the human body; The moisture in the pool dissipates; The water on the open water dissipates.
