🔍 Key Concepts

• Function of a metering device in a refrigeration system • How thermal expansion valves control refrigerant flow based on superheat • Difference between solenoid valves, back pressure regulators, and king valves

💭 Think About

• Ask yourself: Which device actually MEASURES or RESPONDS to evaporator conditions to control how much refrigerant enters that evaporator? • Which option is primarily used for on/off control versus precise flow metering based on temperature/load? • Which device is associated with maintaining a certain pressure in the evaporator rather than directly metering flow into it?

✅ Before You Answer

• Identify which component is specifically designed as a metering device in standard refrigeration terminology • Confirm which device uses a sensing bulb to react to evaporator outlet temperature/superheat • Eliminate any devices whose main job is isolation, simple on/off control, or pressure regulation, not actual metering
