What is the purpose of the compressor in an HVAC system?

The purpose of the compressor in an HVAC system is to compress the refrigerant gas. This process is essential for the refrigeration cycle, where the compressor increases the pressure and temperature of the refrigerant. By doing so, the compressor transforms low-pressure refrigerant vapor into high-pressure vapor. This high-pressure gas then moves to the condenser, allowing it to release heat as it condenses into a liquid. The efficiency of the entire cooling process relies on the compressor’s ability to properly compress the refrigerant, which is crucial for maintaining the necessary pressure differences throughout the system. Without this function, the system would not be able to effectively circulate refrigerant and ultimately provide cooling effect.
