What is the main purpose of the valves shown...

🔍 Key Concepts

• Identify the type of refrigeration component shown by the bulb with capillary tube mounted on the valve body • Recall what variable this type of valve senses and adjusts: temperature and pressure at the evaporator outlet • Connect that sensed variable to what it actually controls in the evaporator outlet vapor

💭 Think About

• Look closely at the sensing bulb and small tube: where in a refrigeration system is that bulb normally strapped, and what property is it reading? • Ask yourself: does this valve directly control liquid level, gas temperature, or condenser performance—and at which point in the system? • Which option best describes what happens to the refrigerant gas right after it leaves the evaporator when this valve opens or closes slightly?

✅ Before You Answer

• Verify which choices refer to conditions at the evaporator outlet, not in the condenser or at a solenoid valve • Make sure the function you pick involves controlling the state of the refrigerant vapor (not just liquid flow amount by itself). • Eliminate any option that talks about components not shown in the illustration (like a separate box solenoid).

What is the main purpose of the valves shown in the illustration? See illustration GS-RA-06.

maintain a constant degree of superheat in the gas leaving the evaporator coil

regulate refrigerant condensation rate in the condenser coil

control the quantity of liquid refrigerant leaving the evaporator coil

control the operation of the box solenoid valve
