🔍 Key Concepts

• Behavior of lubricating oil in multi-compressor systems • Effects of parallel operation on shared suction/discharge lines • What typical failure modes actually occur first in refrigeration systems (evaporator, TXV/expansion valve, condenser, or oil system)

💭 Think About

• Which of these components (evaporators, expansion valves, lubricating system, condenser) is most sensitive to small differences between two compressors running together? • If two compressors are not perfectly matched, what could flow from the higher-pressure crankcase to the lower-pressure crankcase? • Think about what is commonly equalized or carefully managed when a system is designed for parallel compressor operation.

✅ Before You Answer

• Identify which option involves crankcase pressures and oil circulation, not just refrigerant pressure • Ask: which failure would be gradual but serious, rather than an immediate dramatic failure like burst condensers or failed evaporators? • Verify which component normally has specific piping or equalizing lines when multiple compressors are intentionally run in parallel.

Question 1 of 20

Unless the system is designed for such operation, two compressors should not be operated in parallel in a refrigeration system for what reason?

the evaporators would fail due to excessively low suction pressure

operation of two compressors will overload the expansion valves

lubricating oil may be transferred from one compressor to the other

condenser pressure will be too high causing condenser failure
