The persistence of water temperature depends on the adjustment of indoor air temperature in addition to proper heating according to the water temperature condition every day. If the indoor temperature is lower than the temperature of the water, the heat of the pool water will evaporate quickly, and the indoor ceiling and walls will appear dripping, which will simply corrode the building; if the indoor temperature is too high, it will appear hot and make swimmers feel breathing when swimming. Unwell.
Generally, the temperature of indoor swimming pools should be 2-3° higher than the water temperature, so that the water temperature is not easy to evaporate, and the pool water can always maintain the proper temperature.
