🔍 Key Concepts

• Thermostatic expansion valve (TXV or TEV) operation in a shipboard refrigeration system • Relationship between bulb temperature, bulb pressure, and refrigerant flow through the expansion valve • What the sensing line actually carries: pressure from where to where

💭 Think About

• Think about what the thermal bulb is strapped to and what change it is trying to detect in the evaporator coil. • When the evaporator outlet gets warmer, what must happen to the refrigerant flow, and which device in the system actually meters that flow? • Ask yourself: does the sensing line move liquid, electrical signals, or pressure, and to which component does it send that signal?

✅ Before You Answer

• Identify which component in the options actually controls refrigerant flow into the evaporator (not just on/off control). • Confirm that the sensing line is associated with temperature-sensitive pressure changes rather than with direct box air temperature or simple solenoid actuation. • Eliminate any choices that confuse evaporator pressure regulation with superheat control at the evaporator outlet.
