Abstract：

 In order to avoid the influence of condensation in winter on the normal operating of swimming pools, it must consider the calculation of anti-condensation in HVAC design as well as corresponding measures. Presents an overview of a swimming pool in severe cold zone, and calculates the inner surface temperature of the building envelope and the moisture gain of the swimming pool. The results show that the inner surface temperature of the glass curtain wall and roof sunlight board of the swimming pool in winter is close to the dew point temperature. Therefore, the roof of swimming pool in severe cold and cold zones should not be equipped with skylights and transparent plates as far as possible, and the measures should be taken to dry hot air in order to reduce the risk of condensation and the impact on the comfort of personnel.
