Abstract
Air conditioning is one of the indispensable conditions of well-being in human life, so
the face of this research to provide this basic necessity in remote areas and in desert places far
from power grids. To achieve this goal, solar air conditioning has been adopted, where the
compressor was replaced by an ejector, a parabolic trough solar collector coupled with a thermal
generator and a small pump; this means that the solar air conditioner does not need a huge
amount of electrical energy to operate. This paper is studding the optical and thermal efficiency of
the solar collector used as a solar thermal generator, refrigeration subsystem performance
(COPejc) and system thermal ratio of the studied air conditioner, where the cooling load is
estimated at 18 kW. This work has allowed to acquire very important knowledge about R718
ejector solar air conditioners. Bouzaréah was chosen as the region to conduct this numerical
study on June 11th, 2018. Regarding performance of the studied air conditioning subsystem
(COPejc) is 0.6235. As for the PTC solar reflector subsystem, its mean optical performance is
75.74 % and its mean thermal performance is 65.01 %. Regarding the overall performance of the
studied air conditioner, its mean value is 0.407
