Simulation of the working process of an oil flooded helical screw compressor with liquid refrigerant injection.

Author(s) : TANG Y., FLEMING J. S.

Summary

In the paper a mathematical model for the working process of a refrigeration helical screw compressor is presented and discussed. The manner in which geometric parameters such as cell volume, sealing line length, blow hole area, discharge port area, etc are related to rotation angle is established and used in the thermodynamic model which is based on real gas laws. The influence of factors such as the degree of oil flooding, liquid refrigerant injection, vapour charge from the economizer, different refrigerants and partial loading etc, are considered simultaneously and separately in the model. The theoretical basis of the program is described in the paper. Moreover in order to confirm the computer model, the performance predicted by it is compared with the results from compressor tests. The results are compared for different operating conditions.
