Refrigeration Compressor Energy Saving Retrofit | VFD and Heat Recovery Modification
Wasted energy potential causes 30% of cold storage excessive electricity cost, xiteliduo Refrigeration Compressors introduces energy saving retrofit schemes. Piston refrigeration compressor energy saving retrofit mainly adopts optimized rack logic and hot gas heat recovery; VFD retrofit is rarely recommended. Semi-hermetic refrigeration compressor fixed speed unit can be retrofitted with VFD to realize continuous capacity adjustment and reduce part-load power consumption. Cold storage refrigeration compressor heat recovery system reclaims discharge gas heat for hot water supply or warehouse defrosting. Energy saving retrofit payback period is normally 2~4 years for continuous 24-hour running cold storage. 10 recommended hot search keywords: cold storage refrigeration compressor, piston refrigeration compressor, semi-hermetic refrigeration compressor, refrigeration compressor energy saving retrofit, refrigeration VFD retrofit, refrigeration heat recovery, refrigeration part-load efficiency, refrigeration compressor manufacturer, cold storage power saving project, refrigeration compressor supplier
FAQ
Q1: What percentage of cold storage high electricity cost comes from untapped energy saving potential? A: 30% of excessive power consumption comes from unutilized energy saving potential. Q2: What is the main energy-saving method for piston compressor rack? A: Optimized rack control logic and discharge gas heat recovery. Q3: What benefit of VFD retrofit for fixed-speed semi-hermetic compressor? A: Continuous capacity regulation and lower power consumption under partial load. Q4: What usage of recovered heat from compressor discharge gas? A: Produce hot water or supply heat for evaporator defrost. Q5: What typical payback period of energy saving retrofit for 24h cold storage? A: Payback period: 2~4 years. Q6: Why VFD retrofit is not commonly used for piston compressor? A: Piston compressor adopts cylinder unloading for step capacity regulation. Q7: What prerequisite must be checked before energy-saving transformation? A: Compressor mechanical condition and system cleanliness must be qualified.
