The first throttling element 5 is connected to the other end of the indoor heat exchanger 9, and the first throttling element 5 and the other end of the outdoor heat exchanger 3 are connected in parallel with the first circulation passage 6 and the second circulation passage 7 . That is to say, the first circulation passage 6 and the second circulation passage 7 are connected between the other end of the outdoor heat exchanger 3 and the first throttling element 5 , and the first circulation passage 6 and the second circulation passage 7 are arranged in parallel.

The electronic control system includes an electronic control module (not shown in the figure) and an electronic control radiator 4. The electronic control radiator 4 is arranged on the first circulation path 6, and the electronic control radiator 4 is arranged adjacent to the electronic control module to control the electronic control module To perform heat absorption and cooling, specifically, the electronically controlled radiator 4 has a refrigerant channel 40 for circulating the refrigerant, and the refrigerant channel 40 is configured as a part of the first circulation passage 6, that is to say, the part that enters the first circulation passage 6 The refrigerant flows through the refrigerant channel 40 in the electronically controlled radiator 4 .

The controller 8 controls one of the first flow path 6 and the second flow path 7 to conduct, that is to say, when one of the first flow path 6 and the second flow path 7 is turned on, the first flow path 6 and the other of the second flow path 7 are not in conduction.

Specifically, the controller 8 is connected to the electronic control module, and the electronic control module controls the controller 8 to control one of the first circulation passage 6 and the second circulation passage 7 to conduct according to the operating state of the heating and cooling air conditioner 100, more specifically , when the heating and cooling air conditioner 100 is in cooling operation, the first circulation path 6 is conducted, and the second circulation passage 7 is not conducted; when the heating and cooling air conditioner 100 is in heating operation, the second circulation passage 7 is conducted, and the second circulation passage 7 is conducted.

The temperature of the refrigerant is lowered to be close to or slightly higher than the outdoor ambient temperature. Since the controller 8 controls the conduction of the first circulation passage 6 and the non-conduction of the second circulation passage 7, the refrigerant discharged from the outdoor heat exchanger 3 enters the electronically controlled radiator 4 on the first circulation passage 6, and the refrigerant In the electronically controlled radiator 4, the electronically controlled module absorbs heat and cools down.

During the cooling operation, the refrigerant discharged from the outdoor heat exchanger 3 whose temperature is close to or slightly higher than the outdoor ambient temperature enters the electronically controlled radiator 4 to absorb the electronically controlled module. In addition, the refrigerant in the refrigeration cycle passes through the electronically controlled radiator 4, which not only ensures a good cooling effect on the electronically controlled module, but also solves the problem that the condensation water affects the reliability of the electronically controlled module. During the heating cycle, the refrigerant discharged from the first throttling element 5 is discharged into the outdoor heat exchanger 3 through the second circulation passage 7, thereby preventing the low-temperature refrigerant from reducing the temperature of the electronic control module too low, The reliability of the electronic control module during the heating operation of the heating and cooling air conditioner 100 can be guaranteed.
