[0065] Fresh air valve 25 is arranged on the casing 4 at the air inlet side of condenser 21 in the condensing cavity 12, and fresh air valve 25 is also embedded and installed in the inside of the corresponding side plate of casing 4.

[0066] In this embodiment, it is further preferred that the total heat exchanger 16 is installed obliquely in the casing 1, the first angle (the angle between the inlet of the first flow channel and the outlet of the second flow channel of the total heat exchanger 16) of the total heat exchanger 16 is fixedly connected with the casing 1 through a support 29, which is open between the supports 29, and the condensing return air directly enters the condensing cavity 12 when the dehumidifying evaporator 23 does not need to work. The second angle (the angle between the outlet of the first flow channel and the outlet of the second flow channel of the total heat exchanger 16) of the total heat exchanger 16 is fixedly connected with the casing 1 through a partition plate, which separates the outlet of the first flow channel and the outlet of the second flow channel of the total heat exchanger 16.
