Refrigeration compressor effect on cryogenic refrigerator:
(1), cryogenic refrigerator compressor working conditions, can't exceed compressor using conditions of the factory.
(2), selection of piston compressor, when the cryogenic refrigerator condenser pressure and the ratio of the evaporating pressure is less than or equal to 8, should be in the form of single stage compressor;
When the condensing pressure and the ratio of the evaporating pressure is greater than 8 should adopt two-stage compressor type.
(3), cryogenic refrigerator compressor selection to meet the requirements of cryogenic refrigerator production peak cooling load, load were selected according to the evaporation temperature of the machine, in order to meet the mechanical load requirements of different evaporation temperature refrigeration equipment.
(4), cryogenic refrigerator compressor with energy control device, can adjust for stand-alone refrigerating capacity was substantial.
But is only applicable to load fluctuations in the operation of the adjustment, adjustment should not be used as a seasonal load changes.
(5), the determination of single machine capacity and the Numbers should be to choose according to the principle of good for energy saving.
6, different evaporation system with compressor, alternative between each system should be considered, as far as possible the same series of compressors, swap is easy to control, management and spare parts, a series of cryogenic refrigerator compressor selected should not be more than two, such as when only two machines should choose the same series.
