The electronic expansion valve III plays a role in throttling and pressure reduction. And the electronic expansion valve IV and the electronic expansion valve II are both closed.
At the moment, after being discharged by the compressor, the refrigerant flows into an outdoor heat exchanger through the four-way valve to be condensed and radiated; and then the air is throttled by the electronic expansion valve III and flows into the indoor heat exchanger for evaporation and heat absorption, and the air supply is cooled, so that the indoor temperature is reduced. Then, the refrigerant flows through the four-way valve and the gas-liquid separator and then flows back to the compressor, and the circulation is completed.
2. Dehumidification reheating mode: as shown in fig. 3, the four-way valve is in an OFF state, and the electronic expansion valve I is fully opened and does not play a throttling role; the electronic expansion valve III and the electronic expansion valve IV play roles in throttling and pressure reduction; the electronic expansion valve II is closed.
At the moment, after being discharged by the compressor, the refrigerant flows into an outdoor heat exchanger through the four-way valve to be condensed and radiated; then, the air is divided into two paths, wherein one path of air flows into an indoor heat exchanger for evaporation and heat absorption after being throttled by an electronic expansion valve III, and the air is cooled and dehumidified; and the other path of the air passes through the reheating heat exchanger to continue radiating, and the temperature of the dehumidified low-temperature air supply is increased to reach the set air supply temperature. Then, the refrigerant flows into the indoor heat exchanger to evaporate and absorb heat after being throttled by the electronic expansion valve IV. Finally, the refrigerant of the indoor unit flows through the four-way valve and the gas-liquid separator through the gas pipe and then flows back to the compressor, and the circulation is completed.

At the moment, after being discharged by the compressor, the refrigerant is divided into two paths, wherein one path of refrigerant enters the liquid inlet pipe after passing through the four-way valve and the outdoor heat exchanger, and is condensed and radiated in the outdoor heat exchanger; the other path enters the humidifying heat exchanger through the humidifying air pipe for condensation and heat dissipation, and then flows into the liquid pipe. The two paths of refrigerants are converged and then divided into two paths again, one path of refrigerant enters an indoor heat exchanger for evaporation and heat absorption after being throttled by an electronic expansion valve III, and the supplied air is cooled and dehumidified; the other path of the heat flows into a reheating heater for continuous heat dissipation, and then enters an indoor heat exchanger for evaporation and heat absorption after being throttled by an electronic expansion valve IV. Finally, the refrigerant in the indoor unit flows into the outdoor unit through the air pipe, and flows back to the compressor after passing through the four-way valve and the gas-liquid separator, so that the circulation is completed. Meanwhile, under the heat dissipation effect of the humidifying heat exchanger, moisture on the humidifying membrane can be quickly evaporated to form water vapor, and the water vapor is sent into a room by the humidifying fan to humidify the room. Meanwhile, the air supply after cooling and dehumidification is heated up through condensation heat dissipation of the reheating heat exchanger, so that the refrigeration temperature and humidity control of indoor air can be realized.

Then, the refrigerant of the indoor unit flows into the outdoor unit through the air pipe, and then flows back to the compressor through the four-way valve and the gas-liquid separator, thereby completing the cycle. Under the heat dissipation effect of the humidifying heat exchanger, moisture on the humidifying membrane can be quickly evaporated to form water vapor, and the water vapor is sent into a room by the humidifying fan to humidify the room, so that the humidifying effect during refrigeration is realized.

The other path of the air flows into the humidifying heat exchanger for condensation and heat dissipation after passing through the humidifying air pipe, and then flows into the outdoor unit through the liquid pipe. Then, the refrigerant flowing into the outdoor unit is throttled by the electronic expansion valve I, enters the outdoor heat exchanger for evaporation and heat absorption, finally flows through the four-way valve and the gas-liquid separator and then flows back to the compressor, and the circulation is completed. During the period, under the heat dissipation effect of the humidifying heat exchanger, the moisture on the humidifying membrane is quickly evaporated to form water vapor, and the water vapor is sent into the room by the humidifying fan, so that the room is humidified while the temperature is raised.
7. Air supply humidification mode: as shown in fig. 8, the four-way valve is in the OFF state, and the electronic expansion valve I performs a throttling function. The electronic expansion valve II is opened but does not play a throttling role. And the electronic expansion valve III and the electronic expansion valve IV are both closed.
