Compressor efficiency is low, the cooling capacity can not meet the warehouse load requirements
Compressor due to long-term operation, cylinder liner and piston rings and other components due to serious wear and tear, with the gap increases, the sealing performance will be a corresponding decline in the compressor gas transmission coefficient also will be reduced, the cooling capacity will be reduced. When the cooling capacity is less than the heat load of the Treasury, it will lead to a slow decline in the temperature of the Treasury. Can be observed by the compressor suction and exhaust pressure to determine the compressor's cooling capacity. If the compressor cooling capacity is reduced, the commonly used method is to replace the compressor cylinder liner and piston ring, if the replacement can not be effective, you should consider other factors, and even disassemble repair, troubleshooting factors.
