The refrigerated warehouse compressor stops and starts frequently, over and over again. This not only fails to achieve the desired fresh - keeping and refrigeration effects, but is also very detrimental to the quality of the refrigerated warehouse itself.

Moreover, it is certain to waste electricity. Because when the temperature in the refrigerated warehouse reaches the preset temperature, the refrigerated warehouse will automatically stop, which will not cause power consumption due to long - term operation of the refrigerated warehouse, nor will it cause the stored items in the refrigerated warehouse to be frost - damaged. However, many refrigerated warehouses now have this problem: the refrigerated warehouse starts and pauses frequently.

What are the causes of this phenomenon? And how to eliminate this hidden danger?

The reasons for the frequent starting and stopping of the refrigerated warehouse compressor are as follows:

The suction pressure is too low or the cut - off value of the low - pressure relay is set too high.
The discharge pressure is too high and the cut - off value of the high - pressure relay is set too low.

Solutions to the frequent stopping and starting of the refrigerated warehouse compressor:

Adjust the opening degree of the expansion valve and readjust the cut - off value of the low - pressure relay.
Increase the rotation speed of the air cooler or adjust the cut - off value of the high - pressure relay.

When installing a refrigerated warehouse, it is necessary to clearly identify the refrigerated warehouse construction engineering company selected. Regarding the equipment and installation accessories used, only genuine products with qualified quality should be chosen. Otherwise, many problems will occur during the later use of the refrigerated warehouse, causing unnecessary troubles.
