🔍 Key Concepts

• Basic vapor-compression refrigeration cycle (compressor → condenser → receiver → expansion valve → evaporator → back to compressor) • Effect of compression on temperature of a gas (what happens to gas temperature when you compress it?) • Where the refrigerant is high-pressure superheated gas versus where it is liquid or low-pressure gas

💭 Think About

• Trace the path of the refrigerant and identify in which component it is a high-pressure gas rather than a liquid or low-pressure vapor. • Think about which component is doing work on the refrigerant and how that affects its temperature. • For each option, ask: is the refrigerant mostly gas or liquid there, and is it being compressed or expanding?

✅ Before You Answer

• Be sure you know which line is the discharge (outlet) and which is the suction (inlet) of the compressor. • Confirm in your cycle diagram where the refrigerant is in a superheated, high-pressure gaseous state. • Eliminate locations where the refrigerant is mostly liquid or low-pressure vapor, because those will not be the highest temperature point.

In a typical refrigeration system, where is the temperature of the refrigerant gas at the highest?

at the compressor discharge

at the compressor suction

in the expansion valve

in the receiver
