When the heat pump drying device is used for drying in a reverse circulation mode, the fan rotates in a reverse direction, air flows from the second heat exchanger 32 to the fourth heat exchanger 52, and the circulation of the heat pump system is as follows: the refrigerant discharged from the exhaust port of the compressor 1 is partially sent to the first heat exchanger 31, partially enters the fourth heat exchanger 52 after passing through the four-way valve 2, is condensed and released heat by the fourth heat exchanger 52, then enters the second heat exchanger 32 after passing through the second throttling device 42 (fully opened and un-throttled), is continuously condensed and released heat, is throttled and reduced in pressure by the third throttling device 43, is mixed with the refrigerant which is condensed and released heat by the first heat exchanger 31 and is throttled and reduced in pressure by the first throttling device 41, enters the third heat exchanger 51 for evaporation and heat absorption, finally returns to the air suction port of the compressor 1, is discharged after being compressed, and completes the whole cycle. In this case, the second heat exchanger 32 and the fourth heat exchanger 52 are both condensers.
When the fan rotates in the forward direction, namely, forward circulation, when air entering the material to be dried from the second heat exchanger 32 in the drying room needs to be humidified, the water atomization device 103 is started, water from the water storage tank 105 or tap water enters the water atomization device 103 through the water pump 101 and the heating device 102, at the moment, if the water level detection device in the water storage tank 105 judges that condensed water exists in the water, the water pump 101 is started, and the three-way valve 106 is switched to realize that the water required for atomization comes from the water storage tank 105; if the water level detection device in the water storage tank 105 judges that the condensed water is insufficient, the water pump 101 is not started, and the three-way valve 106 is switched to realize that the water required by atomization comes from tap water; the start and stop of the heating device 102 is judged and adjusted by the temperature of the water entering the water atomization device 103.
