Summary

In single screw refrigeration compressor (SSRC), the liquid refrigerant injected into the working chamber is used to reduce the exhaust gas temperature and improve the compressor performance. In this paper, a new calculation model of the injection process considering internal compression, leakage and heat transfer is presented based on the meshing principle of the meshing pair and the working mechanism of the SSRC with injection. By this model, the actual capacity and injection quality can be obtained using the calculated effective injection area. The influence of the structural parameters such as the initial position and the injection-hole diameter to the characteristics of the injection process and the thermodynamic properties of the SSRC are analyzed. Through the comparison of the injection process with different structural parameters, optimization analysis of the structural parameters can be obtained. All of this work can provide the basis for the later optimization design of the injection process.
