In this paper, the refrigerant flow and the thermal performance of a working fluid pump are performed in the perspective of an ejector refrigeration system. The influence of impeller's geometric parameters on the internal pressure, flow rate and cavitation of the pump is studied experimentally and numerically. A vertical multi-stage centrifugal pump is selected as an experimental prototype for numerical verification, and a working fluid pump, which is optimized by the orthogonal analysis, is numerically studied, the results show that the optimized one has better thermal performance than the prototype.
