When multiple refrigerated boxes are maintaining individual temperatures and supplied by a single refrigeration compressor, the individual box temperatures are controlled by what action?

🔍 Key Concepts

• How a single compressor can serve multiple refrigerated spaces with different temperature settings • The role of solenoid valves in starting/stopping refrigerant flow to individual boxes • The difference between system capacity control (compressor loading/speed) and individual box temperature control

💭 Think About

• Ask yourself: If one compressor is serving several boxes, what has to happen at each box so that one can cool while another does not? • Which component can completely stop or allow refrigerant flow to a particular box without changing the operation of the compressor itself? • Which of the listed actions would affect the entire system versus just one box at a time?

✅ Before You Answer

• Identify which options change compressor output for the whole system rather than one box • Identify the component that acts like an on/off valve for refrigerant flow to a single box • Confirm which device is normally controlled by a box thermostat to maintain that box’s set temperature
