Refrigerator compressor is adjusted
On the refrigerator compressor adjustment is to heat load of refrigeration andwarehouse makes the compressor to adapt.
For goods 1, freezing room due to the influence of heat load, will increase thetemperature of the refrigerant into the warehouse, the more cargo,transportation time is longer, the higher the temperature rise. At this time,should first draw single stage compressor cooling, the temperature to reducepressure greater than or equal to 8:1, then change the double stage compressor refrigeration system cooling. But must pay attention to: such as the operation of the distribution group double stage compressor change thesingle stage compressor operation, or the single stage compressor matched group in the operation of double stage compressor operation, must be in a stopped state, change after reboot.
2, compression refrigeration capacity is greater than the cold heat load, under normal circumstances, adjusting device can be part of the unloading operationusing compressor energy, if conditions allow, can also be a change of refrigeration compressor refrigeration capacity of small.
3, in the operation, and has stopped cooling cold room connection: should firstsuction valve of compressor opening adjustment is small, then slowly openingregulating station check valve, to observe the gas temperature and pressure,and then adjust the suction valve of compressor opening, until the appropriatedate.
