Abstract
An ejector compression system for cooling is introduced which utilizes low-grade energy freely available from renewable resources like solar energy, bio waste etc. In this paper the performance of system is evaluated applying the conservation principles of mass and energy on ejector considering it as a control volume. The behavior of the ratio of mass flow rate of fluid from evaporator to the mass flow rate of fluid from generator, COP and cooling effect by varying the condenser/evaporator temperature have been observed. The refrigerant R1234yf which has low ODP and GWP has been used and the analysis has been done with the help of Engineering Equation Solver (EES) Software. Maximum COP of the system is found to be 0.3458 at the evaporator temperature 10°C, condenser temperature 30°C and generator temperature 70°C.
