Optimization Design and Application of Multi-function Variable Conditions Refrigeration Unit

Based on the characteristics and requirements of mine heating and refrigeration thermodynamics, the multi-function heat pump refrigeration unit is optimal designed, and two screw compressors used as refrigeration compressor of the multi-function unit are selected. The preferably switching working condition is achieved under the compression ratio change largely, which has a good load adjustment capability and adaptability. By the running test shows that the multi-function variable conditions refrigeration unit and its system can meet different functional requirements and achieve the design purpose.
