Résumé

Air source heat pump heating has been widely used for energy conservation especially in cooler climes. Compressor displacement directly affects the heating capacity of an air source heat pump system. The application of enhanced vapor injection in an air source heat pump can greatly increase the compressor displacement in low temperature environments. In this paper, in order to analyse the internal flow and suction and exhaust conditions of the rotary compressor with vapor injection, a three-dimensional dynamic numerical model was built up by using the commercial CFD (computational fluid dynamics) solvers FLUENT and dynamic grid technique. And the theoretical model is used to verify the correctness of the simulation model. The simulation results of rotary compressor with and without the injection port are compared and analysed. The effect of the injection port on suction and discharge of the rotary compressor has been investigated in this study.
