🔍 Key Concepts

• Thermostatic expansion valve (TXV) operation and what the sensing bulb actually measures • Difference between a liquid-charged power element and other types (e.g., gas-charged, cross-charged) • What happens to the refrigerant charge in the bulb as temperature rises to the normal operating range

💭 Think About

• Think about what the sensing bulb of a liquid-charged TXV is supposed to do as the evaporator reaches its designed operating temperature: how does bulb pressure get created? • If the bulb were completely empty of liquid under normal conditions, what would that do to its ability to respond to small temperature changes? • Would good valve sensitivity come from a bulb that keeps some liquid present, or from one that is fully vapor at normal operating temperature?

✅ Before You Answer

• Clarify in your mind whether a liquid-charged bulb is intended to retain some liquid at normal operating temperatures or to boil completely to vapor. • Check which options describe a condition that would improve the valve’s sensitivity, and which options describe a condition that would reduce it. • Before choosing, ask: under normal, designed operating temperature, is the bulb expected to be completely vapor or to still contain some liquid refrigerant so pressure changes follow temperature closely?
