🔍 Key Concepts

• How a thermostatic expansion valve (TXV or TEV) senses temperature and pressure • The meaning of superheat in a refrigeration system • What condition at the evaporator outlet the system designer usually wants to keep stable

💭 Think About

• Think about where the sensing bulb of the thermostatic expansion valve is located and what variable it is actually measuring. • Ask yourself: is the valve trying to keep the box (cargo space) at a fixed temperature, or is it trying to protect the compressor and keep refrigerant in the right state leaving the evaporator? • Consider what happens if liquid refrigerant reaches the compressor—what parameter does the valve control to prevent that from happening?

✅ Before You Answer

• Identify which option refers to a condition at the evaporator outlet, not in the box or throughout the whole system. • Decide which parameter, if kept constant, best ensures that only vapor (no liquid) leaves the evaporator. • Verify which choice matches the typical control objective of a TXV sensing bulb strapped to the suction line near the evaporator outlet.
