Electric refrigerant compressor selection

Electric refrigerant compressor is the main equipment of the refrigeration unit, and its investment cost in the refrigeration unit cost also accounted for a relatively large. Whether the choice of electric refrigerant compressor is reasonable, for the economy of the refrigeration unit, the construction cost and the operation of most of the regulation have a great impact.


 

Electric refrigerant compressor selection has the following principles.

Electric refrigerant compressor working conditions, can not exceed the factory specified conditions of use of the compressor.
Replacement piston ammonia compressor, when the ratio of condensing pressure to evaporating pressure is less than or equal to 8, a single-stage compressor form should be used; when the ratio of condensing pressure to evaporating pressure is greater than 8, a two-stage compressor type should be used.
Compressor selection to meet the requirements of the production of refrigeration devices peak refrigeration load, according to the evaporation temperature of the size of the machine load separate, alternative refrigeration devices of various different evaporation temperature mechanical load requirements.
Compressor with energy regulation device, you can make the adjustment range of the single machine cooling capacity. But only for the operation of the adjustment of the load change, should not use the adjustment of the shift static change.
Single-unit capacity and the number of units to determine, should be replaced by the principle of facilitating energy saving.
Different evaporative systems equipped with compressors, should consider the mutual replacement between the systems, using the same series of compressors, can control, management and spare parts interchangeable, a refrigeration unit replacement compressor series should not exceed two, such as only two machines should replace the same series.
