What is the structural principle of a compressor?

After being cooled and turned into a high-pressure, low-temperature liquid through the condenser's cooling tubes, it then passes through the receiver-drier for dehumidification and buffering, flowing toward the expansion valve with relatively stable pressure and flow rate. After throttling and pressure reduction, it finally flows into the evaporator. The refrigerant evaporates immediately upon encountering a low-pressure environment, absorbing a large amount of thermal energy. The following are specific details about the compressor: 1. Classification: Air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. 2. Function: The air conditioning compressor plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. The working circuit is divided into an evaporation zone (low-pressure zone) and a condensation zone (high-pressure zone). The indoor unit and outdoor unit belong to the high-pressure or low-pressure zone respectively (depending on the working state), and the compressor is generally installed in the outdoor unit. The compressor draws the refrigerant from the low-pressure zone, compresses it, and sends it to the high-pressure zone for cooling and condensation, releasing heat into the air through the heat sink. The refrigerant also changes from a gaseous state to a liquid state, with increased pressure. The refrigerant then flows from the high-pressure zone to the low-pressure zone, being sprayed into the evaporator through the capillary tube, where the pressure drops sharply, and the liquid refrigerant immediately turns into a gaseous state, absorbing a large amount of heat from the air through the heat sink. As the machine continuously operates, it continuously absorbs heat from the low-pressure zone into the refrigerant and then releases it into the air in the high-pressure zone, thereby regulating the temperature.
