The air conditioner with defrosting and dehumidifying functions has the following working principle:
when the air conditioner runs in the refrigeration mode, the electromagnetic valve is closed, and the heat pipe circulation system driven by the heat of the motor of the compressor 1 does not participate in the work, so that the air conditioner performs refrigeration circulation according to the conventional air conditioner refrigeration system.
When the air conditioner operates in a heating mode, the electromagnetic valve is opened, and the air conditioner performs refrigeration cycle according to a conventional air conditioner heating system. The heat pipe circulation system driven by the heat of the motor of the compressor 1 normally works, the compressor 1 compresses the gaseous refrigerant, the motor of the compressor 1 produces a large amount of heat to be transferred to the third heat exchange pipeline 6, the refrigerant in the third heat exchange pipeline 6 absorbs heat and evaporates into the gaseous refrigerant after being heated, the pressure in the third heat exchange pipeline 6 rises due to the gaseous expansion, the gaseous refrigerant is driven to rise into the second heat exchange pipeline 22 of the indoor unit 2 to be radiated and condensed into liquid refrigerant, and the liquid refrigerant flows out from an outlet at the lower part of the second heat exchange pipeline 22 and enters the third heat exchange pipeline 6 of the compressor 1 again to be circulated again due to the action of gravity. In this process, the heat generated by the motor of the compressor 1 is brought to the second heat exchange pipeline 22 in a heat absorption and evaporation mode, and the heat is released into the room in a condensation and heat generation mode, so that the heating quantity is increased, and the temperature of the room is increased.
When the air conditioner receives a defrosting instruction, the reversing valve 5 is switched to a refrigerating mode, the indoor fan rotates down, and the outdoor fan is closed. The compressor 1 discharges the high-temperature and high-pressure refrigerant, the reversing valve 5 reaches the outdoor unit 3 to perform condensation heat release, the frost outside the outdoor unit 3 is melted, the normal-temperature refrigerant reaches the first heat exchange pipeline 21 of the indoor unit 2 to absorb heat and evaporate after being throttled by the capillary tube, the temperature of the first heat exchange pipeline 21 is reduced, at the moment, the temperature of the first heat exchange pipeline 21 is extremely low, and the temperature of the air passing through the position is low. The solenoid valve is opened, and the heat pipe circulation system driven by the heat of the motor of the compressor 1 works normally, and in this process, the heat generated by the motor of the compressor 1 is brought into the second heat exchange pipeline 22 in a form of heat absorption and evaporation. At this time, the temperature of the second heat exchange pipeline 22 is higher, and the air reaches the second heat exchange pipeline 22 with higher temperature from the first heat exchange pipeline 21 with lower temperature and is heated, and at this time, the air discharged from the air conditioner is normal-temperature air.
When the air conditioner receives a dehumidification instruction, the reversing valve 5 is closed, the indoor fan operates according to the set wind speed, and the outdoor fan is normally opened. The compressor 1 discharges the high-temperature and high-pressure refrigerant, the reversing valve 5 achieves the outdoor unit 3 to perform condensation heat release, the normal-temperature refrigerant reaches the first heat exchange pipeline 21 of the indoor unit 2 to absorb heat and evaporate after being throttled by the capillary tube, the water in the air is removed from the air after being condensed after passing through the first heat exchange pipeline 21, the temperature of the first heat exchange pipeline 21 is reduced, at the moment, the temperature of the first heat exchange pipeline 21 is extremely low, and the temperature of the air passing through evaporation heat exchange is also low. The solenoid valve is opened, and the heat pipe circulation system driven by the heat of the motor of the compressor 1 works normally, and in this process, the heat generated by the motor of the compressor 1 is brought into the second heat exchange pipeline 22 in a form of heat absorption and evaporation. At this time, the temperature of the second heat exchange pipeline 22 is higher, and the air reaches the second heat exchange pipeline 22 with higher temperature from the first heat exchange pipeline 21 with lower temperature and is heated up, so that the effect that the air after the room is dehumidified is not cooled is achieved.
