A thermal expansion valve installed in a refrigeration system is controlled by the action of what device?

Question 1 of 27070

A thermal expansion valve installed in a refrigeration system is controlled by the action of what device?

🔍 Key Concepts

• Thermal expansion valve (TEV) function in a refrigeration cycle • How superheat at the evaporator outlet is sensed and controlled • Which component is directly connected (physically and functionally) to the TEV

💭 Think About

• Which choice actually measures the temperature/pressure of the refrigerant coming out of the evaporator to adjust refrigerant flow? • Which of these devices is normally strapped or clamped onto the evaporator outlet line in common marine and commercial refrigeration systems? • Which listed components (solenoid coil, receiver level controller, sensing bulb, compressor unloader) act as a "remote sensor" versus an on/off or capacity control device?

✅ Before You Answer

• Identify which option is a temperature/pressure sensing device rather than a switch or control valve • Confirm which component is normally mounted on or near the evaporator outlet/tail coil, not on the compressor or receiver • Eliminate any device that mainly controls capacity or liquid level, rather than metering refrigerant based on superheat
