Abstract


The Solar Thermal Cooling System mainly comprises of Solar Panels, Generator, Condenser and Evaporator. In addition an ejector is mounted in the existing system to improve the performance of the system. The Ejector is having a primary and secondary inlet nozzle. In the primary flow nozzle the motive refrigerant will flow with high pressure which comes from generator. The area of the ejector is reduced to increase the pressure by means of venturi effect. Due to high velocity of motive refrigerant, the negative pressure is created inside the suction chamber which in turn sucks the low pressure refrigerant from the evaporator. The mixture of high pressure motive refrigerant and the low pressure refrigerant passes into the condenser at moderate pressure and the cyclic process is continued. The main scope of the project is to fabricate only the ״ejector״.
