[0028] Refrigeration cycle: in hot weather, the indoor heat exchanger 3 absorbs the heat of indoor air, the refrigerant in the circuit passes through the expansion valve 7, then passes through the compressor 5, and finally releases heat in the outdoor heat exchanger 4, and then returns to the indoor heat exchanger 3; the cycle is repeated to achieve indoor refrigeration.

[0029] Heating cycle: in cold weather, the outdoor heat exchanger 4 absorbs the heat of outdoor air, passes through the compressor 5, passes through the expansion valve 7, and finally releases heat in the indoor heat exchanger 3, and then returns to the outdoor heat exchanger 4, and the cycle is repeated to achieve indoor heating.

The evaporation section and the condensation section are respectively arranged in the air inlet channel 9 and the air outlet channel 8 which are not connected to each other. Preferably, the air inlet channel 9 is connected in series with an air filter device 11. Preferably, the inlet of the air outlet channel 8 and the inlet of the air inlet channel 9 are respectively provided with fans.

[0031] The heat pipe heat exchanger 1 is annularly arranged around the indoor heat exchanger 3 of the air conditioning system, and the pipe body is arranged in the indoor air conditioning heat exchanger.

[0032] Summer fresh air circulation: the air outlet channel 8 (inlet) inhales the turbid air in the room, and passes through the condensation section of the heat pipe heat exchanger 1; at the same time, the air inlet channel 9 (inlet) inhales fresh air, and passes through the evaporation section of the heat pipe heat exchanger 1; the fresh air and the turbid air are exchanged in the heat pipe heat exchanger 1, the fresh air recovers part of the cold energy of the turbid air to become fresh air, and enters the room from the air inlet channel 9 (outlet); the turbid air is discharged from the air outlet channel 8 (outlet) to the outside.

[0033] Winter fresh air circulation: the air outlet channel 8 (inlet) inhales the turbid air in the room, and passes through the evaporation section of the heat pipe heat exchanger 1; at the same time, the air inlet channel 9 (inlet) inhales fresh air, and passes through the condensation section of the heat pipe heat exchanger 1; the fresh air and the turbid air are exchanged in the heat pipe heat exchanger 1, the fresh air recovers part of the heat of the turbid air to become fresh air, and enters the room from the air inlet channel 9 (outlet); the turbid air is discharged from the air outlet channel 8 (outlet) to the outside.

In order to ensure the comfort of human body, the indoor design temperature is 24 DEG C, and the relative humidity is selected as 50%. In order to ensure the fresh air of the indoor air, the fresh air supply of 20-30 m 3 / h per person is usually selected, but considering that the introduction of a large amount of fresh air will increase the indoor heat load and cause the waste of energy, the fresh air supply of 20 m 3 / h per person is selected.

[0036] Compared with the traditional evaporator-based refrigeration and dehumidification, the outlet temperature of the household air conditioner after the application of the heat pipe is increased from 24 DEG C to 25.41 DEG C, which is more suitable for the demand of human comfort on the indoor temperature, and the temperature is increased by about 5.88%; the dehumidification capacity is increased from 4.02 kg / h to 4.75 kg / h, and the dehumidification capacity is increased by about 18.2%.
