Piston Refrigeration Compressor Working Condition Adaptation | Suitable Cold Storage Application Scenarios
Piston refrigeration compressors can stably operate within evaporating temperature from -40℃ to +10℃, which covers most medium and low temperature cold storage requirements. xiteliduo Refrigeration Compressors shares working condition adaptation data.
Piston refrigeration compressor cooling capacity will drop by 18% when evaporating temperature falls from -10℃ to -25℃. This is the inherent characteristic of reciprocating compression structure.
Semi-hermetic refrigeration compressor has better stability under frequent start-stop cycles. It can withstand 12 start-stop operations per hour without accelerating component wear.
Cold storage refrigeration compressor ambient operating temperature limit is 43℃. Continuous running above this threshold will increase the risk of overheating protection shutdown.
About 68% of small fresh-keeping cold storage adopts piston refrigeration compressor. This proportion comes from the statistical data of domestic cold storage equipment installation projects.
