Abstract:
Energy saving has become an important issue due to the limited energy resources and the increasing demands. Many studies have been carried out to improve energy efficiency. In this perspective, the vapor compression cycle (VCC) systems equipped with an ejector as an expansion device are considered to improve the COP by reducing the expansion loss and compressor work. This paper presents simulation results on the performance of the ejector vapor compression cycle (EVCC) using low-GWP refrigerants. The vapor compression cycle system equipped with an ejector as an expansion device is considered to improve the coefficient of performance (COP) by reducing expansion losses and compressor work. The EVCC was simulated using a model based on the conservation of mass, energy, and momentum in the ejector. Based on the simulation results, the COP improvement of the EVCC was analyzed under varying operating conditions and compared with that of the conventional vapor compression cycle (VCC). The EVCC showed greater performance improvements with increasing temperature differences between the condenser and evaporator for all refrigerants.
