Compressor because of the long time operation of cold storage, cylinder liner and piston ring parts because of wear, clearance increased sealing performance will be degraded, the volumetric efficiency of the compressor has reduced and cooling capacity will be reduced. When the quantity of refrigerant when the heat load is less than the Treasury, will result in the warehouse temperature drops slowly. May be obtained through observation compressors, exhaust pressure to determine the cooling capacity of the compressor. If the cooling capacity of the compressor, and commonly used method is to replace the compressor cylinder and piston rings if replaced still does not works, you should consider other factors, even disassemble and repair, troubleshooting.
