Description

Compressor assembly and vehicle having same

technical field

The invention relates to the technical field of compressors, in particular to a compressor assembly and a vehicle with it

Background technique

The compressor assembly in the related art usually includes a compression component. The compression component operates to compress the refrigerant to generate a pressure difference, compress the low-pressure and low-temperature gaseous refrigerant sucked into the suction port into a high-pressure and high-temperature gaseous refrigerant, and discharge it from the exhaust port to form a physical conversion of the refrigerant and flow.

When the compressor assembly is working in summer, due to the high ambient temperature, the work of the compression part is increased when the gas is compressed, resulting in a high temperature of the compression part (for example, exceeding 80 ° C), and a large discharge pressure, which in turn causes the internal pressure of the compression part. If the difference is too large, the probability of motor out-of-step and shutdown will be increased. After the compressor assembly is shut down, the static difference in the compression parts needs to be eliminated before the compressor assembly can be restarted. It takes a long time to eliminate the static difference. During the waiting time for the static difference to be eliminated, the air conditioner will stop working, reducing user comfort. After the compressor assembly stops, if the static difference of the compression parts is not eliminated and the compressor assembly is started, the load capacity of the power device (for example, IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor)) in the compressor assembly will be exceeded The risk will cause damage to power devices or reduce the life of power devices. Therefore, in order to solve the above problems, some compressor components usually increase the margin of power devices, but this will increase the production cost.

In addition, when the compressor components work in winter, the performance of the compressor components is different, such as the increase of the viscosity of the refrigeration oil and the change of the motor stator parameters, etc., so it is easy to cause the compressor components to fail to start, and due to the principle of thermal expansion and cold contraction Components are subject to slight deformation that may prevent the compression component from functioning properly.
