Compressors used in refrigeration systems care rack

The compressors of a refrigeration system are sized to work continuously. It is frequent to observe stops in compressors due to conditions such as fluctuation of the store's thermal load. Therefore, it is not always the fact that a compressor is stopped is a sign of trouble in the compressor. The compressor must always be kept clean so that any oil leakage can be quickly identified. The cycling of a compressor, starting and stopping at short intervals of time, can be detrimental to it, since at the moment of departure its components are not fully lubricated. In addition, at starting the compressor motor current can reach a value of 7 (seven) times the nominal current of the compressor, producing heating of the windings that can lead to premature aging of the insulation, failing. Thus, successive starts of compressors can cause mechanical or electrical failures in the compressor.
