In a multi-evaporator refrigeration system,...

🔍 Key Concepts

• Basic flow path of a vapor-compression refrigeration system (compressor → condenser → receiver → expansion device → evaporator → back to compressor) • Purpose of a solenoid valve in refrigeration (automatic on/off control of liquid refrigerant flow) • How multiple evaporators are independently controlled in a multi-evaporator system

💭 Think About

• Think about which component needs to be controlled so that each evaporator can be turned on or off without stopping the whole system. • Ask yourself: where should a solenoid valve be placed so that it can stop refrigerant flow right before it enters the low-pressure side? • Which of the choices is the device that directly feeds refrigerant into each evaporator and therefore would logically be controlled individually?

✅ Before You Answer

• Verify the normal sequence of components in the liquid line after the receiver and condenser. • Identify which listed device actually meters or controls the pressure drop into the evaporator. • Confirm that the solenoid valve’s role is to control liquid refrigerant flow to each evaporator rather than to common components like the condenser or receiver.

In a multi-evaporator refrigeration system, a solenoid valve is installed in the liquid line prior to what device?

the receiver

each expansion valve

the condenser

the oil separator
