Or discontinuous mode air-supply；Wherein, △ RH is the humidity differences, and rh1 and rh2 are the threshold value in the preset psychrometric difference section,
R1 < R2, K1 < K2, rh1 > rh2.
5. control device according to claim 4, which is characterized in that further include that press adjusts unit, be used for:
Preset the corresponding relationship between the psychrometric difference section and the raising frequency rate of the compressor；With the maximum of the compressor
Running frequency is the upper limit, according to the matching result and the corresponding relationship, controls the compressor with corresponding raising frequency rate
Promote the running frequency of the compressor, comprising:
As △ RH >=rh1, the running frequency that the compressor promotes the compressor with the first raising frequency rate H1 is controlled；
As rh2≤△ RH < rh1, the operation frequency that the compressor promotes the compressor with the second raising frequency rate H2 is controlled
Rate；
As △ RH < rh2, the running frequency that the compressor promotes the compressor with third raising frequency rate H3 is controlled；
Wherein, H1 > H2 > H3.
6. a kind of air-conditioning, which is characterized in that including air-conditioner body and such as described in any item control devices of claim 4-5.
