ABSTRACT
This paper present theoretical analysis for a solar refrigeration process to generate cold air for air conditioning by parabolic collector in Al-Samawa city conditions. The working fluid in the cooling cycle is water only, which is used as refrigerant fluid. The mathematical description based on the conservation equations of mass, energy, momentum, some gas dynamic equations, and state equations, is made to understand the flow inside the ejector. Engineering equation solver (EES) software is used to solve the nonlinear partial differential equations. The objective of work is to study the performance of solar-ejector conditioning system, on 21st day of July and December months in 2011 according to Al-Samawa climates condition the different from other city is by received solar intensity and the position of the city in longitude and latitude lines. The results of performance of the system show that the coefficient of performance between (0.05-0.33) with cooling capacity between (0.1-0.56) KW during the day for a collector of 10.5 m2 area.
