🔍 Key Concepts

• Thermal expansion valve (TXV) controls refrigerant flow based on superheat • The sensing bulb measures temperature of the refrigerant leaving the evaporator • Bulb must be placed where refrigerant is in the gas phase, not mixed liquid-gas

💭 Think About

• Ask yourself: where do we most accurately measure the superheat of the refrigerant to protect the compressor from liquid slugging? • Which location on the evaporator will give the bulb a stable, representative temperature of the suction gas returning to the compressor? • If the bulb were placed where liquid and vapor are mixed, how would that affect its ability to control flow correctly?

✅ Before You Answer

• Make sure the chosen point is after most of the heat absorption has occurred in the evaporator • Confirm the bulb is on a line carrying superheated vapor, not primarily liquid refrigerant • Verify the location is close to where refrigerant goes back toward the compressor (suction line side)
