The following describes the structure and the action principle of the air source heat pump unit 100 in the energy-saving circulating multistage linkage kitchen waste organic fertilizer treatment equipment provided by the application:
the low temperature and low pressure, medium temperature and high pressure and high temperature and high pressure refer to a characteristic change process of a refrigerant in a heat exchange process, the high temperature and the low temperature are relative pressure change processes, the low temperature, the medium temperature and the high temperature are progressive temperature change processes, and specific pressure values and temperature values take actual values in specific application scenes as references.
The compressor 110 is a driven fluid machine that lifts low-pressure gas into high-pressure gas, sucks low-temperature low-pressure refrigerant gas from a suction pipe, drives a piston to compress the low-temperature low-pressure refrigerant gas by motor operation, and then discharges high-temperature high-pressure refrigerant gas (gaseous refrigerant) to an exhaust pipe to power a refrigeration cycle.
The condenser is a partition wall type heat exchanger with one side being high-temperature gaseous refrigerant and the other side being cooling medium air or water, so as to realize heat exchange, and the condenser is mainly divided into two types: water-cooled and air-cooled. The water-cooled condenser can be further divided into: immersion type, vertical shell and tube type, horizontal shell and tube type, sleeve type and plate change type condensers. The air cooling type condenser adopts a fin heat exchanger, heat released by refrigerant in the condenser is taken away by air, the refrigerant is condensed in a pipe, and the air cooling type condenser comprises a natural convection air cooling type condenser and a forced convection air cooling type condenser, wherein the forced convection air cooling type condenser is mainly provided with a fan for forced convection heat exchange.
The expansion valve 130 may throttle the liquid refrigerant (liquid refrigerant) of high temperature and high pressure to be wet vapor of low temperature and low pressure, and then the refrigerant flows into the evaporator 140 to absorb heat to achieve a refrigerating effect. In use, the flow regulation of the expansion valve 130 is realized by the superheat change at the tail end of the evaporator 140.
The evaporator 140 mainly comprises a heating chamber and an evaporating chamber, the heating chamber provides heat required for evaporating liquid refrigerant, so that liquid is boiled and vaporized, steam generated in the heating chamber carries a large amount of liquid foam, and after the liquid refrigerant flows into the evaporating chamber, the liquid refrigerant is separated from the steam by the action of self-condensation or a foam remover and the like, so that the gas-liquid two phases are completely separated.
The air source heat pump unit 100 used for the air energy hot water circulating type kitchen waste drying treatment equipment preferably uses the fin heat exchanger 120, and the fin heat exchanger 120 is arranged on the outer wall of the medium box 150.

After the high-temperature and high-pressure gaseous refrigerant compressed and discharged by the compressor 110 enters the fin heat exchanger 120, heat exchange is performed between the gaseous refrigerant and the medium in the medium box 150 so as to heat the medium in the medium box 150, and after the medium-temperature and high-pressure liquid refrigerant flow which completes heat exchange sequentially flows through the expansion valve 130 and the evaporator 140, the gaseous refrigerant becomes low-temperature and low-pressure gaseous refrigerant, and the low-temperature and low-pressure gaseous refrigerant enters the compressor 110 and is compressed into the high-temperature and high-pressure gaseous refrigerant and then enters the next cycle. The air source heat pump does not need to absorb the refrigerant from the outside, and the refrigerant discharged from the evaporator 140 can be sent to the compressor 110 for circulation.
Therefore, the air source heat pump unit 100 heats the medium in the medium tank 150 by adopting the inverse Carnot principle, and energy in the air is transferred to the medium instead of directly heating by using an electric heating element, so that the energy efficiency of the air source heat pump unit can reach 4 times of that of the electric water heater. If the same amount of hot water is heated, the power consumption is equal to one fourth of that of the electric water heater, so that the power consumption is greatly saved, and the carbon emission is reduced.

The heat exchange outlet 220 of the exhaust heat exchanger 200 may be connected to an inlet of the expansion valve 130 in the air source heat pump unit 100, so that the refrigerant continues to participate in the processing cycle of the air source heat pump unit 100.
One of the values is that the humidity value in the drying bin can be detected by a humidity sensor arranged in the drying bin, and when the air humidity in the drying bin is too high, that is, the humidity value detected by the humidity sensor exceeds a set value, the refrigerant in the fin heat exchanger 120 is led into the exhaust heat exchanger 200. In specific implementation, the first electromagnetic valve 160 may be disposed on a pipeline for connecting the heat exchange outlet of the fin heat exchanger 120 and the inlet of the expansion valve 130, and the second electromagnetic valve 170 may be disposed on a pipeline for connecting the heat exchange outlet of the fin heat exchanger 120 and the heat exchange inlet of the exhaust heat exchanger 200, the opening and closing actions of the first electromagnetic valve 160 and the second electromagnetic valve 170 are controlled by a controller, the controller is connected with a humidity sensor signal, a humidity set value is stored in the controller, and when the humidity value in the drying bin detected by the humidity sensor exceeds the set value, the opening and closing of the first electromagnetic valve 160 and the second electromagnetic valve 170 may be controlled to realize the direction of the refrigerant in the fin heat exchanger 120.

Meanwhile, when the temperature in the drying bin rises and reaches a certain humidity, a fan connected with the drying bin is started, waste gas enters the steam exhaust heat exchanger 200, refrigerant in the steam exhaust heat exchanger 200 returns to the compressor 110 through the expansion valve 130 after heat exchange is completed, the medium box 150 is subjected to supplementary heating after the temperature is compressed and raised by the compressor 110, at the moment, the compressor 110 of the air source heat pump unit 100 stops absorbing air energy in the atmosphere, the refrigerant in the steam exhaust heat exchanger 200 circulates, and the heat energy source of the air source heat pump unit 100 is switched to waste gas waste heat.
