This study describes a thermoeconomical
analysis for an ejector cooling system. The energetic, exergetic and economic
analyses of an ejector cooling system are investigated by using four different operating
conditions. The influences of generator, evaporator, condenser, expansion valve
and pump on thermoeconomical factors of the ejector cooling system are showed
up. The results indicated that the thermoeconomic factors of the ejector
cooling system are dependent on the operating condition and the system
components’ irreversibility.
