What is the function of a compressor in an HVAC system?

The function of a compressor in an HVAC system is to pump refrigerant through the system and compress it. This process is essential for the refrigeration cycle, which is the core mechanism that enables air conditioning and refrigeration systems to work effectively.

When the refrigerant enters the compressor, it is in a low-pressure vapor state. The compressor increases the pressure of this refrigerant, which raises its temperature and allows it to move to the condenser. By compressing the refrigerant, the compressor ensures that it can absorb heat from the indoor air when it passes through the evaporator coil. This is crucial for the system's ability to cool the air effectively.

In addition to its primary role of compressing the refrigerant, the compressor also helps maintain the flow of refrigerant throughout the system, ensuring that the cooling process is continuous and efficient. Its proper functioning is vital for the entire HVAC system to operate correctly and provide the desired indoor climate comfort.
