The performance of which component is indicated by the amount of sub-cooling in a refrigeration system?

• A. Evaporator
• B. Compressor
• C. Condenser
• D. Accumulator

Answer: (C)

The performance of the condenser in a refrigeration system is indicated by the amount of sub-cooling. Sub-cooling refers to the process of cooling the refrigerant beyond its condensation point, ensuring that it is fully condensed before it enters the expansion device or evaporator. In a condenser, the refrigerant vapor releases heat as it condenses into a liquid. If the refrigerant continues to lose heat after it has condensed, it becomes sub-cooled. The degree of sub-cooling is critical as it ensures that no vapor enters the expansion valve. This enhances the efficiency of the refrigeration cycle, improves overall system performance, and helps prevent potential damage or wear that might result from any vapor entering components downstream. In contrast, while the evaporator, compressor, and accumulator have specific roles in the refrigeration cycle, they do not directly measure or reflect sub-cooling. The evaporator is focused on absorbing heat to convert the refrigerant from liquid to vapor, the compressor is responsible for increasing the pressure of the vapor refrigerant, and the accumulator's purpose is to collect any excess liquid refrigerant to prevent it from returning to the compressor. Thus, the performance characteristic linked specifically to sub-cooling indeed points to the condenser.
