Problems solved by technology
[0010] However, when the outdoor air conditioner works in the cooling mode, its working environment is usually at a high temperature, and the compressor needs to release heat during the working process, which makes the temperature of the compressor itself and the exhaust temperature both rise.
An increase in the temperature of the compressor itself may cause the compressor to overheat and cause damage to the compressor
The rise in exhaust temperature may cause damage to some components in the outdoor air conditioner
In addition, the higher the exhaust temperature, the greater the workload of the outdoor heat exchanger to complete the heat exchange, so the energy consumption of the outdoor air conditioner will also increase

The embodiment of the invention provides an outdoor air-conditioning unit and an air-conditioning system, which relate to the field of air conditioners and can reduce the temperature of a compressor and the exhaust temperature. The concrete scheme is as follows: the outdoor air-conditioning unit comprises the compressor, an air-side stop valve, a liquid-side stop valve, an outdoor heat exchanger and a liquid replenishing branch, wherein the compressor comprises an exhaust port, an air suction port and a replenishing port; in a cooling mode, a refrigerant discharged from the exhaust port of the compressor enters the outdoor heat exchanger; and part of the liquid refrigerant discharged out of the outdoor heat exchanger flows out of the outdoor air-conditioning unit through the liquid-side stop valve, and the other part of the liquid refrigerant enters the compressor through the replenishing port of the compressor via the liquid replenishing branch. The invention is used for manufacturing of the outdoor air-conditioning unit and the air-conditioning system.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to an outdoor air conditioner and an air conditioning system. Background technique [0002] combine figure 1 A schematic diagram of an air conditioning system is shown. A compressor 101 of an outdoor air conditioner includes a suction port 102 , an exhaust port 103 and an air supply port 104 . [0003] During the working process of the outdoor air conditioner, the refrigerant flows into the compressor 101 from the suction port 102 , and flows out from the discharge port 103 after being compressed. [0004] The air supply port 104 is used to supply air to the compressor 101 during the heating process, so as to improve the heating effect. Specifically, in the heating mode, after the refrigerant flows out from the exhaust port 103, it flows into the indoor heat exchanger 106 through the four-way reversing valve 105 to liquefy and release heat. After the refrigerant flows out of the i...
