🔍 Key Concepts

• Operation of a reciprocating refrigeration compressor after idle periods • Function and location of the suction valve, king valve, and expansion valve in a refrigeration system • Why you might need to prevent liquid slugging or overload when first starting a compressor

💭 Think About

• Think about which valve directly controls what is entering the compressor cylinders at startup. • Ask yourself: when a compressor has been idle, what are you most worried about getting into the cylinders—gas, liquid, or something else? Which valve helps you control that? • Consider which valve you would adjust gradually to let conditions stabilize (pressures, temperatures) before going to full open.

✅ Before You Answer

• Identify which component is upstream of the compressor inlet and directly affects what flows into it. • Confirm which valve is normally used for pumping down or isolating the receiver, versus which valve is used to regulate refrigerant into the evaporator. • Verify which valve, when throttled, will protect the compressor from liquid refrigerant entering it during initial startup.
