Abstract

Meeting the energy demand and reducing high energy costs are becoming more and more essential for mankind. Concordantly, increasing scientific studies are trying to provide new techniques and solutions every day. In the area of refrigeration technology, which is the cause of a considerable part of the energy consumption, very significant studies are being done to increase energy efficiency. Ejector cooling technology, which is supposed to be able to replace conventional cooling systems, is an area of research that attracts the attention of researchers and that various researches are being carried out on them. In this study, theoretical performance analysis of an ejector cooling system that is using R123 as refrigerant and designed according to the constant area model has done. In the cooling system, the ejector is considered as the substitute of the compressor. The theoretical analysis of the system was carried out by using a computer program which is being used for modelling and simulation. All the data belong to the thermodynamic properties of R123 refrigerant were processed to the program. By using this data in the prepared program, it is possible to simulate desired values according to different situations and conditions. Thus, the effects of using R123 refrigerant on the coefficient of performance (COP) of the cooling system under various operating conditions are examined and the findings are presented in graphs.
