Red Seal Refrigeration and Air Conditioning Mechanic Practice Exam

The primary function of a compressor in a refrigeration system is to raise the pressure of refrigerant gas and circulate it through the system. In a refrigeration cycle, the compressor plays a critical role by taking in low-pressure, low-temperature refrigerant gas and compressing it to a high-pressure, high-temperature gas. This increase in pressure is essential because it enables the refrigerant to release heat when it flows through the condenser, thereby allowing the entire refrigeration cycle to function effectively. The compressor also ensures proper circulation of the refrigerant throughout the system, moving it to different components like the condenser and evaporator. This circulation is vital for transferring heat away from the space being cooled and maintaining the efficiency of the refrigeration system. Understanding the compressor's function helps in diagnosing issues within the system and performing maintenance effectively.
