What component is responsible for changing low pressure refrigerant to high pressure vapor?

The component that changes low-pressure refrigerant to high-pressure vapor is the compressor. In a refrigeration cycle, the compressor's primary function is to compress the refrigerant, raising its pressure and temperature. When the refrigerant enters the compressor as a low-pressure gas, it is compressed into a smaller volume, which increases its pressure significantly. This high-pressure vapor is then pumped into the condenser, where it releases heat and transitions into a high-pressure liquid. Understanding the role of the compressor is essential, as it is a crucial part of the refrigeration cycle, facilitating the movement of refrigerant through the system by managing the pressure differentials needed for effective heat exchange.
