In order to supplement heat when the heat provided by the fresh air reheating solution heat recovery heat exchanger is insufficient, an electric heater 13 is arranged on the fresh air side, and when the temperature of the fresh air passing through the fresh air reheating solution heat recovery heat exchanger does not reach a set value, the electric heater 13 starts to work.
As the fresh air reheating solution heat recovery heat exchanger 1-1 is additionally arranged, and the humidifier 10 is arranged on the side of the fresh air reheating solution heat recovery heat exchanger 1-1, a large amount of condensed water can be generated when cold air meets the fresh air reheating solution heat recovery heat exchanger 1-1, in order to collect the condensed water completely and prevent breeding bacteria from entering a room along with fresh air, a water receiving disc 18 is arranged below the fresh air reheating solution heat recovery heat exchanger 1-1.
