As a typical representative city of China’s hot and humid climate zone, Chongqing has an average annual relative humidity of 70% - 80%. Continuous online monitoring of indoor air quality (IAQ) were conducted in more than 20 residents of Chongqing city. It was found that the apartments in the area had excessive indoor absolute humidity in summer (far exceed the ASHRAE recommended comfort limit—12g/kg) and excessive indoor relative humidity in winter and transitional seasons. It is necessary to dehumidify the outdoor intake air during the summer and decrease the indoor related humidity during the winter and transition seasons. Based on the above two points, it is proposed to adopt a fresh air system with dehumidification function in Chongqing, which can remove excessive absolute humidity caused by outdoor air in high humidity month. The fresh air system, which changes natural ventilation to mechanical ventilation, increase indoor insulation effect and reduce relative humidity.
