In order to improve the working reliability of the compressor, this technical solution proposes a compressor including:

The compressor body 100 has a heat exchange channel for the flow of cooling medium. The compressor body 100 is provided with a first inlet 130 and a first outlet 140 that are independent of each other. The first inlet 130 and the first outlet 140 are used to circulate the refrigerant. The hot channel flows through the first inlet 130 and the first outlet 140;

The cooling medium is used to heat the refrigerant when the refrigerant temperature at the first inlet 130 is lower than the cooling medium temperature, and to cool the refrigerant when the refrigerant temperature at the first outlet 140 is higher than the cooling medium temperature.

In addition, the compressor also has mutually independent The first inlet 130 and the first outlet 140 are provided for allowing refrigerant to enter and exit the compressor body 100 for compression. In addition, the heat exchange channel flows through the first inlet 130 and the first outlet 140 . The first outlet 140 is configured in such a way that under low temperature conditions in winter, when the temperature of the cooling medium in the heat exchange channel is higher than the refrigerant medium, the cooling medium can heat the refrigerant, so that the refrigerant is compressed before compression. Increasing the initial temperature will help reduce the power consumption required by the compressor to compress the refrigerant. It will also help improve the working reliability of the compressor under extreme low temperatures and ensure its normal operation. In high-temperature conditions such as summer, the cooling The medium can cool the refrigerant at the first outlet 140, which is beneficial to improving the efficiency of refrigerant refrigeration and reducing the power consumption required by the compressor to compress the refrigerant.

The heat exchange channel flows through the first inlet 130 on the compressor body 100. position and the position of the first outlet 140. In this way, when the refrigerant enters the compressor body 100 from the first inlet 130, the cooling medium in the heat exchange channel can conduct heat exchange with the refrigerant through the compressor body 100. Under low temperature conditions, The cooling medium can be heated by the PTC heater and then enter the heat exchange channel, and heat the refrigerant at the first inlet 130. This can make the refrigerant easy to compress, thereby improving the efficiency of the compressor, and also prevents the refrigerant from being too low due to low temperature. As a result, the compressor cannot compress normally; at the first outlet 140, since the refrigerant is compressed into a high-temperature and high-pressure state, the cooling medium can cool the refrigerant. In this way, under high-temperature conditions such as summer, the cooling medium can reduce the temperature of the refrigerant. The temperature of the compressor and the refrigerant can prevent the compressor from being too high, affecting its lifespan and reducing its working reliability. In addition, to ensure that the temperature of the cooling medium is stable after heat exchange, the compressor body 100 is also provided with a second inlet 210 and a second outlet 220.

In this way, the cooling medium can flow into the pipeline at the same time and perform heat exchange with the stator. In low temperature conditions such as winter, the cooling medium can heat the stator to ensure that the stator is The rotor works at a suitable temperature, and when the stator temperature is too high, the cooling medium can cool down the stator and rotor to prevent them from being damaged due to excessive temperature.
