How To Choose A Refrigeration Compressor
Mar 01, 2020
The selection of refrigeration compressor has the following principles:
① The Du working conditions of the refrigeration compressor Bai machine should not exceed the compressor service conditions specified by the factory.
② When piston type ammonia compressor is selected, when the ratio of condensation pressure to evaporation pressure is less than or equal to 8, single-stage compressor shall be adopted; when the ratio of condensation pressure to evaporation pressure is greater than 8, double-stage compressor shall be adopted.
③ The selection of compressor should meet the requirements of peak cooling load of refrigeration device, and the machine load of each evaporation temperature should be selected separately to meet the mechanical load requirements of different evaporation temperatures.
