🔍 Key Concepts

• Thermal expansion valve (TXV) sensing element and bulb location • The difference between evaporator pressure and superheat • What parameter the TXV must sense to prevent liquid refrigerant from returning to the compressor

💭 Think About

• Where is the TXV sensing bulb normally installed in a refrigeration system, and what does it measure? • What physical change tells the TXV that more or less refrigerant should flow into the evaporator? • Which of the choices represents a condition at or very near the evaporator outlet rather than in the cooled space or at another valve?

✅ Before You Answer

• Identify what the sensing bulb of a TXV is strapped to and what it detects there. • Distinguish between space (box) temperature and refrigerant temperature/pressure in the line. • Verify which option is directly related to controlling superheat at the evaporator outlet rather than general system pressure drop.
