What is the Structural Principle of a Compressor?

[McEmily]

After being cooled and condensed into a high-pressure, low-temperature liquid through the condenser's cooling tubes, it passes through the receiver-drier for dehumidification and buffering, then flows to the expansion valve at a relatively stable pressure and flow rate. After throttling and pressure reduction, it finally flows into the evaporator. The refrigerant evaporates immediately upon encountering the low-pressure environment, absorbing a large amount of thermal energy. Below is a detailed explanation regarding the compressor: Classification: Air conditioning compressors can be divided into fixed-displacement compressors and variable-displacement compressors. 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, where the heat is dissipated into the air through the radiator fins, and the refrigerant 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, where it is sprayed into the evaporator through the capillary tube, causing a sudden pressure drop, and the liquid refrigerant immediately turns into a gaseous state, absorbing a large amount of heat from the air through the radiator fins. As the machine continuously operates, it 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.
