Frequently Asked Questions
Q: How should hot gas defrost cycles be managed to protect this semi hermetic reciprocating compressor?
A: Ensure a suction liquid accumulator is fitted to catch unevaporated liquid returned during defrost termination, and delay full capacity loading until system pressures normalize.
Q: What expansion valve setting precautions prevent oil dilution in low-temperature evaporators?
A: Maintain stable superheat (at least 5-8 K at the compressor suction inlet) to prevent wet compression and keep refrigerant from dissolving excessive lubricant in the crankcase.
Q: What maximum pressure limits apply during system pressure testing and leak checking?
A: Perform pressure testing using dry nitrogen, ensuring test pressures do not exceed the compressor low-side or high-side design limits (housing pressure limit is 28 bar).
Q: How often should compressor oil be replaced during continuous commercial operation?
A: Change the initial oil charge after the first 100 hours of run-in, and subsequently conduct oil analysis or replacement every 10,000 operational hours or once a year.
