🔍 Key Concepts

• Refrigeration flow path: compressor discharge → condenser → receiver → expansion device → evaporator → back to compressor • Difference between discharge (high-pressure) side and suction (low-pressure) side of a compressor • How a service valve sits in the line: the port at the bottom of the valve body connects directly to the line coming from or going to the compressor

💭 Think About

• On a standard marine refrigeration system, where does the refrigerant go immediately after it leaves the compressor? • If valve "D" is specifically called a discharge service valve, is it on the high-pressure side or low-pressure side, and which component does that side feed first? • Looking at the illustration, is port "7" below or above the valve seat in relation to the compressor, and would that location be on the inlet or outlet of the compressor?

✅ Before You Answer

• Be sure you know which side of the compressor is suction and which is discharge in the cycle. • Confirm that a discharge service valve is installed directly on the compressor’s discharge (high-pressure) connection, not on the condenser itself. • Verify that port 7 is the passage that continues in line with the compressor connection, so it must match whichever side (inlet or outlet) that discharge valve serves.
