The evaporative water tank 20 is fixedly installed in the casing 2.

[0037] Specifically, the refrigeration system and the heating system share the same hot and cold air outlet 9.

[0058] Specifically, the filter element structure includes a filter element 17, a support column 18, and a sealing cover 19.
