[0037] In the heating mode, air flows through the condenser in the shell 1, is heated by the condenser and is sent back to the drying room by the heat exhaust driving piece 41, the first evaporator 21 is not in working condition, so the air is not dehumidified; the compressor 31 compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure refrigerant, the refrigerant is sent to the condenser through the four-way valve, the condenser releases heat to the air in the heat exchange part 4, the heated air is discharged to the drying room through the heat exhaust driving piece 41, the refrigerant is condensed into high-pressure liquid, the air is heated, the high-pressure liquid refrigerant is changed into low-temperature and low-pressure gas-liquid mixture through the electronic expansion valve, and is sent to the second evaporator 32 through the three-way valve, the second evaporator 32 absorbs heat from the external environment, so that the refrigerant is evaporated into low-pressure gas, the low-temperature and low-pressure gaseous refrigerant is returned to the compressor 31 through the four-way valve, and the circulation of the refrigerant is completed.
[0038] In the heating and dehumidifying mode, the first evaporator 21 starts to work, the air in the drying room enters the first evaporation part 2 from the air inlet, is cooled and dehumidified by flowing through the first evaporator 21 first, then enters the heat exchange part 4 through the heat exchange fin 13, is heated by flowing through the condenser, and becomes dry and high-temperature air after being heated, and is sent back to the drying room through the heat exhaust driving piece 41, so that the heating and dehumidifying of the interior of the drying room are realized; the compressor 31 compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure refrigerant, the refrigerant is sent to the condenser through the four-way valve, the condenser releases heat to the air in the heat exchange part 4, the heated air is discharged to the drying room through the heat exhaust driving piece 41, the refrigerant is condensed into high-pressure liquid, the air is heated, the high-pressure liquid refrigerant is changed into low-temperature and low-pressure gas-liquid mixture through the electronic expansion valve, and is sent to the first evaporator 21 through the three-way valve, the air in the drying room treated by the first evaporator 21 is cooled by heat absorption, the refrigerant absorbs heat from the air and is evaporated into gaseous state, and then is returned to the compressor 31 through the four-way valve, so that the circulation of the refrigerant in this mode is completed.
[0039] In cooling and dehumidification mode, air flows through the first evaporator 21 inside the casing 1. After being cooled and dehumidified, it becomes dry and cool air and is sent back to the drying room. The condenser does not participate in the operation, thus avoiding heating the air. The compressor 31 compresses the low-temperature, low-pressure gaseous refrigerant to high-temperature, high-pressure. The high-temperature, high-pressure gaseous refrigerant enters the second evaporator 32 through the switching of the four-way valve. The second evaporator 32 dissipates heat to the external environment and condenses the refrigerant into liquid. The high-pressure liquid refrigerant passes through the electronic expansion valve and becomes a low-temperature, low-pressure gas-liquid mixture. Then, it enters the first evaporator 21 through the three-way valve.

The second evaporator 32 is connected to the suction end of the suction drive 33 by a bracket. When the suction drive 33 is working, ambient air from outside the equipment is drawn into the second evaporation section 3 through the air inlet mesh 34, flows through the fins of the second evaporator 32, and is then discharged from the ventilation openings through the suction drive 33, thereby improving the heat exchange efficiency.
[0041] Reference Figure 2 and Figure 5 The first evaporation section 2 is provided with an air collecting shell 22.

[0042] The air collector shell 22 and the dehumidification drive unit 23 can accelerate the suction of humid air to the fins of the first evaporator 21.
