What is the state of the refrigerant as it enters and exits a condenser?

• A. Low pressure gas in, high pressure liquid out
• B. High pressure gas in, low pressure liquid out
• C. High pressure gas in, high pressure liquid out
• D. Low pressure gas in, low pressure liquid out

Answer: (C)

In a refrigeration cycle, the condenser plays a critical role in the heat exchange process. As refrigerant enters the condenser, it is in a gaseous form and typically under high pressure. This is a result of it having just exited the compressor, where its temperature and pressure were elevated. When the high-pressure gas passes through the condenser, heat is removed from the refrigerant, usually through a cooling medium like air or water. During this heat exchange, the refrigerant condenses into a liquid state. By the time it exits the condenser, the refrigerant is now in a high-pressure liquid state. This transition is crucial as it ensures that the refrigerant is prepared for the next stage of the refrigeration cycle, where it will expand and enter the evaporator. Thus, the correct description of the state of the refrigerant as it enters and exits the condenser is indeed high pressure gas in and high pressure liquid out. Understanding this process is fundamental for operating engineers, as it underlines the principles of thermodynamics applied in refrigeration systems.
