Under normal conditions, how does refrigerant enter and leave the compressor?

In a refrigeration cycle, the function of the compressor is to increase the pressure of the refrigerant. Under normal operating conditions, the refrigerant enters the compressor as a low pressure superheated vapor. This state is crucial because it ensures that the refrigerant does not become liquid during compression, which could damage the compressor.

As the compressor runs, it compresses this low pressure superheated vapor, significantly raising its temperature and pressure. After this process, the refrigerant exits the compressor as a high pressure vapor. This high pressure vapor is then routed to the condenser where it will release heat to the surrounding environment and condense into a liquid.

Understanding the behavior of refrigerant during this phase is fundamental for anyone involved in HVAC or refrigeration systems. The proper function of the compressor directly impacts the efficiency and effectiveness of the cooling system.
