Abstract
For proper comprehend the comportment and to
define the parameters of a solar-driven ejector air conditioning
system at low or medium temperature; a dynamic model depends
on the principles of conservation, the momentum mass and
energy is developed. For this purpose, the thermodynamic
characteristics of the liquid and vapor refrigerant were identified
using the Engineering Equation Solver EES software. Linear
Fresnel Reflector (LFR) has been used as a tool to convert solar
energy into thermal energy. The water (R718) was used as a
refrigerant. The performance of the ejector air conditioning
system was compared as a function of the operating parameters
of the subsystem. The thermal efficiency of the Fresnel linear
concentrator was as high as 31.514 %, and the overall thermal
performance of the machine (STR) was as high as 20.764 %. The
results obtained during this study are very encouraging. This
technique can be used for air conditioning in desert areas in
southern Algeria, where fossil energy (petroleum, gas, etc.) is
extracted and produced in various types.
