Which of the conditions listed will cause a refrigeration compressor to run constantly without simultaneously decreasing the temperature in the refrigerated space?

🔍 Key Concepts

• Refrigeration cycle components: compressor, condenser, expansion valve, evaporator • Effect of refrigerant quantity on suction pressure and cooling capacity • Role of the expansion valve in controlling refrigerant flow to the evaporator

💭 Think About

• Which condition would allow the compressor to keep circulating refrigerant but prevent enough liquid refrigerant from properly expanding and absorbing heat in the evaporator? • Think about what happens to evaporator temperature and suction pressure when there is a small leak versus when the control device feeding the evaporator is not operating correctly. • Which option would most likely cause low cooling (poor evaporation) while still keeping the compressor running continuously in an attempt to reach the set temperature?

✅ Before You Answer

• Check which fault would cause poor refrigerant expansion into the evaporator, reducing heat absorption. • Consider which condition would result in the box temperature staying high, making the thermostat keep the compressor running all the time. • Verify which options mainly affect lubrication or condenser conditions, and whether those would stop cooling altogether, cause short cycling, or just change efficiency slightly rather than causing constant running with no temperature drop.
