摘要：
In order to solve the air-source heat pump can not work well in the cold and serious cold regions. This article carries on the theory and experimental study to the recovery fresh air heat pump units, with the recycled exhaust heat to heat fresh air, has mastered the system operation characteristics and the actual operating results. The experimental results show that the indexes meet the needs of load for heating in winter. The coefficient of performance (COP) is in the value of more than 3.80, and the heat recovery efficiency is up to 82%, which is prolonging the heat pump units and the fresh air units running in the period of heating, maintaining well Indoor Air Quality(IAQ) for a long time.
