In this study, the optimization conditions for the design of an ejector cooling system are investigated theoretically and experimentally. First law of thermodynamics analysis in accordance with the ejector theory is made with water which is the preferred working fluid in the ejector cooling system. Thermodynamic properties such as enthalpy, temperature, mass flow rate and velocity are calculated at each point of the system. The intersection of Rayleigh and Fanno curves, which enables the theoretical acquisition of the shock phenomenon in the throat region of the ejector, is obtained by iteration. In this section, the dimensioning of the ejector is carried out by obtaining optimum value. Cooling coefficient of performance (COP) and entrainment ratio (G) of the ejector cooling system is calculated at different operating conditions. The effect on the coefficient of performance and entrainment ratio of the system parameters are investigated. The obtained numerical results are presented in tables and graphics. The generator temperature is determined as three different values (80, 85 and 90 degrees C) and the results are obtained. It is determined that the cooling performance coefficient (COP) is 0.15-0.42 and the flow entrainment ratio (G) is 0.15-0.45 at different temperatures and pressures. In this study, all theoretical and experimental analyses of cooling systems are carried out As a result, in the theoretical and experimental analyzes of the ejector system, experimental results are found to be similar to theoretically calculated results. |
