🔍 Key Concepts

• Multi-box refrigeration systems usually have one compressor and multiple evaporators (one in each box). • Each box typically has its own temperature control device that starts/stops or admits refrigerant flow to that box when the desired box temperature is reached. • Understand the different roles of a thermal expansion valve, a back pressure regulating valve, a box solenoid, and a low-pressure cutout in the system.

💭 Think About

• Which component in a multi-box system actually responds to the box air temperature in an individual compartment and directly stops or allows refrigerant flow to that box? • Which device is usually controlled by a thermostat inside the box, as opposed to sensing suction pressure or evaporator outlet superheat? • Think about what each option measures or controls: is it box temperature, evaporator outlet superheat, suction pressure, or compressor protection? Which one would be used to control temperature in ONE compartment only?

✅ Before You Answer

• For each choice, identify what physical quantity it senses (box temperature, pressure, or superheat). • Verify which device is typically unique to each compartment in a multi-box system and is controlled by that compartment’s thermostat. • Eliminate any device that mainly protects the compressor or suction line as a whole, rather than controlling just one box.
