Abstract

A dehumidifying device includes a compressor, a heating coil, an expansion valve and a cooling coil which are connected to construct a complete refrigeration cycle. Te dehumidifying device further comprises a condenser connected between the compressor and the heating coil. In such a manner, the condenser has a heat output that is controlled to regulate a temperature in a space, with the dehumidifying device simultaneously controlling the humidity and the temperature in the space.

Claims

1. A dehumidifying device comprising:

a compressor, a heating coil, an expansion valve and a cooling coil which are connected to construct a complete refrigeration cycle;

wherein;

the dehumidifying device further comprises a condenser connected between the compressor and the heating coil; and

the condenser has a heat output that is controlled to regulate a temperature in a space, with the dehumidifying device simultaneously controlling the humidity and the temperature in the space.

2. The dehumidifying device of claim 1, wherein:

the cooling coil includes a first cooling coil and a second cooling coil which are operated alternatingly;

the first cooling coil includes a first defrosting unit and a first electric throttle;

the second cooling coil includes a second defrosting unit and a second electric throttle;

after the first cooling coil performs dehumidifying and frosting to have a predetermined thickness, the second electric throttle is switched to the second cooling coil, with the second cooling coil performing dehumidifying and frosting, and with the first cooling coil performing defrosting; and

the first cooling coil and the second cooling coil are operated successively and periodically to achieve a dehumidifying function under a condition of lower than the dew point of 0°
