Air conditioner heat-radiating circulation system

An air conditioner heat-radiating circulation system, comprising a compressor, a four-way reversing valve having a first interface, a second interface, a third interface and a fourth interface, an outdoor heat exchanger, and an indoor heat exchanger,

• wherein the compressor has a discharge pipe connected to the first interface of the four-way reversing valve, the fourth interface of the four-way reversing valve is connected to a first end of the outdoor heat exchanger, a second end of the outdoor heat exchanger is connected to a first end of the indoor heat exchanger via an electronic expansion valve, a second end of the indoor heat exchanger is connected to the second interface of the four-way reversing valve, the third interface of the four-way reversing valve is connected to an input end of a gas suction pipe, and an output end of the gas suction pipe is connected to the compressor via a gas-liquid separator, wherein the gas suction pipe comprises a refrigerating circulation branch and another branch, the another branch comprises a gas suction electromagnetic valve and is connected with the refrigerating circulation branch in parallel, the refrigerating circulation branch comprises a branch electromagnetic valve and a flat tube micro-channel aluminum-based radiator in series, and the flat tube micro-channel aluminum-based radiator has a temperature sensor, the gas suction pipe is located downstream of the third interface of the four-way reversing valve and upstream of the compressor;
• wherein the four-way reversing valve has a fluid communication configuration for a cooling mode and a fluid communication configuration for a heating mode, when the air conditioner heat-radiating circulation system is configured to be operated in the heating mode, the first interface and the second interface of the four-way reversing valve are in fluid communication and the fourth interface and the third interface of the four-way reversing valve are in fluid communication, so that refrigerant gas outputted by the compressor is introduced into the indoor heat exchanger via the first interface and the second interface and, after sequentially passing through the indoor heat exchanger and the outdoor heat exchanger, is circulated back to the compressor via the fourth interface, the third interface and the gas suction pipe;
• and
• when the air conditioner heat-radiating circulation system is configured to be operated in the cooling mode, the first interface and the fourth interface of the four-way reversing valve are in fluid communication and the second interface and the third interface of the four-way reversing valve are in fluid communication, so that refrigerant gas outputted by the compressor is introduced into the outdoor heat exchanger via the first interface and the fourth interface and, after sequentially passing through the outdoor heat exchanger and the indoor heat exchanger, is circulated back to the compressor via the second interface, the third interface and the gas suction pipe.
