When large amount of warm goods are loaded into cold room in a short time, evaporator heat load rises quickly. If expansion valve responds improperly, excessive liquid refrigerant flows back to compressor suction side.
Liquid flood back differs from liquid hammer. Slight continuous liquid return slowly dilutes refrigeration oil, gradually wearing bearing and piston components, while liquid slugging creates instant impact and directly breaks valve assemblies.
Installing suction accumulator is effective protection for batch loading cold storage. It traps liquid refrigerant and only feeds gaseous refrigerant into piston compressor cylinder.
During cargo loading phase, avoid running compressor at full load at the beginning. Operate with partial capacity to slow down refrigerant circulation and reduce the possibility of liquid return.
Defrosting operation also triggers liquid flood back risk. When frost melts rapidly, liquid refrigerant may migrate to suction pipeline. Defrosting logic should include delay startup for piston compressor.
xtldcool can configure suction accumulator and related protection logic for cold storage piston compressor system for batch loading projects, especially seafood and meat freezing warehouses.
After liquid flood back occurs, stop the compressor immediately. Do not restart repeatedly; inspect oil dilution status and remove liquid refrigerant inside crankcase before commissioning again.
FAQ
Q: Why batch cargo loading increases liquid flood back risk? A: Sudden heat load surge causes excessive liquid refrigerant generation.
Q: What is the difference between liquid flood back and liquid slugging? A: Liquid flood back is slow continuous liquid return; liquid slugging is instant hydraulic impact.
Q: What equipment prevents liquid refrigerant entering compressor? A: Suction accumulator on suction pipeline captures liquid refrigerant.
Q: How to operate compressor safely during goods batch loading? A: Run compressor under partial capacity instead of full load.
Q: What operation may also trigger liquid flood back? A: Rapid defrosting process of evaporator brings liquid migration risk.
Q: What action to take once liquid flood back is detected? A: Shut down compressor immediately and inspect oil dilution condition.
Q: Can xtldcool configure suction accumulator for batch freezing cold storage? A: Yes, we design liquid protection system for batch loading cold storage piston compressor.
