The thermostat controlling the operation of the solenoid valve to a refrigerated box evaporator senses what temperature?

🔍 Key Concepts

• Function of a solenoid valve in a refrigeration system feeding an evaporator • What the thermostat is trying to control in a refrigerated box system • Difference between temperatures inside the box and temperatures in the refrigerant piping

💭 Think About

• Ask yourself: What variable must the thermostat sense in order to maintain the desired product/box condition? • Which of these temperatures would most directly reflect the condition that matters to the cargo or contents of the box? • Which temperatures are more useful for equipment protection or efficiency, rather than controlling how cold the box is?

✅ Before You Answer

• Identify what the control objective of the thermostat is in this system (what is it trying to keep constant). • Distinguish between refrigerant temperatures (inlet/outlet, compressor discharge) and space temperature (inside the refrigerated box). • Verify which of the listed points would change in a way that directly corresponds to the load being placed on the refrigerated box.
