Performance analysis of HVAC twin screw compressor: study with two different refrigerants (R123 and R407C).

Author(s) : ADHIKARY P., BANDYOPADHYAY S., MAZUMDAR A.

Summary

Customized grid generation of twin screw machines for CFD analysis is widely used by the refrigeration and air-conditioning industry today but is currently not suitable for topologies such as those of single screw, variable pitch or tri screw rotors. This study investigates a new technique (key-frame re-meshing) that supplies pre-generated unstructured grids to the CFD solver at different time steps with low-pressure refrigerants (R123 and R407C). There are many limitations to key-frame re-meshing. It requires time consuming pre-processing, has limited applicability to complex meshes and leads to inaccuracies in conservation of calculated variables. It was concluded that customized tools for generation of CFD grids are required for complex twin screw machines.
