What effect does the compressor have on the refrigerant?

The compressor plays a crucial role in the refrigeration cycle by raising both the pressure and temperature of the refrigerant. When the refrigerant enters the compressor, it is typically in a low-pressure, low-temperature vapor state. As the compressor functions, it compresses this vapor, which significantly increases its pressure. According to the principles of thermodynamics, compressing a gas also raises its temperature due to the work being done on the refrigerant.

This change in pressure and temperature is essential because it prepares the refrigerant for the next stage in the cycle, where it will be able to release heat to the environment when it reaches the condenser. The increased pressure also ensures that the refrigerant can move through the system effectively, allowing for heat absorption in the evaporator later on. Thus, understanding the role of the compressor is key to grasping how refrigerants behave throughout the refrigeration cycle.
