在对空气全热交换器在上海市冬季和夏季运行效率进行连续实测的基础上,利用湿度势理论,得到了全热交换器运行效率随室外温湿度变化的规律。 Based on the continuous measurement of the air-to-air heat exchanger operating efficiency in winter and summer in Shanghai, the law of the operating efficiency of the total heat exchanger with the outdoor temperature and humidity was obtained by using the humidity potential theory.
