When the exhaust temperature of the air source heat pump system is higher, the electromagnetic valves 14 between one group or multiple groups of evaporators 3 and the expansion valve 15 are correspondingly closed, the output power of the evaporation fan 4 is controlled, the evaporation area and the evaporation air volume of the system are adjusted, and the stable dehumidification of the unit is ensured.
As shown in fig. 3, when an air-source heat pump dryer is in a dehumidification condition, the operation state of the unit is similar to that in the heating condition corresponding to fig. 1. The difference is that at the moment, the first electric air valve 6 and the third electric air valve 8 are in a half-open state, and the rest air valves are all opened to be fully-open. Due to the influence of the evaporation fan 4, the return air of the drying room mostly enters the machine body through the electric air valve II 7, and the small part enters the machine body through the electric air valve I6, and the wet air of the part flows out of the electric air valve IV 10 after passing through the total heat exchange core body 5 and is mixed with the external air entering from the air inlet valve 11, and then is conveyed through the evaporation fan 4, and the evaporator 3 absorbs heat and is discharged out of the machine body from the air outlet valve 9; meanwhile, due to the influence of the circulating fan unit 1, part of dry and cold air which absorbs heat through the evaporator 3 enters the machine body through the electric air valve III 8, is mixed with hot air entering from the electric air valve II 7, passes through the other group of channels of the total heat exchange core body 5, is heated at the condenser 2, and is conveyed into the drying room through the circulating fan unit 1.
