Semi-empirical modelling and simulation of a cycle for refrigeration compressors testing in superheated region only

摘要

This paper considers the development of a new compressor testing method based on a thermodynamic cycle taking place in the superheated region only. More than an alternative to standard testing methods the proposed superheated cycle would presentsignificant advantages as for example a faster transient change between steady state test conditions. In order to carry out an investigation of the adjusting of operational conditions, the new cycle was modelled and simulated. Preliminary results allow to verify the system behaviour according the change in three control parameters: refrigerant system charge, expansion valve opening, and desuperheater water flow rate. Next steps in this research will consider an experimental implementation of the newtesting method.
