Experimental and numerical investigation on an ejector for CO2 vapor compression systems.
Number: pap. 1392
Author(s) : GIACOMELLI F., BANASIAK K., HAFNER A., et al.
Summary
The use of two-phase flashing ejectors to improve the COP and capacity of CO2 vapor compression systems has become a key research topic in recent years. Although many experimental investigations focused on both the ejector performance and overall energy efficiency have been carried out, further efforts devoted to significantly enhance this device are necessary. In the present paper, the authors experimentally investigated the performance of a two-phase ejector as its main parameters, such as pressure lift and entrainment ratio, are varied. The results are finally compared with a CFD model based on a commercial solver.
