Design and Analysis of Solar Refrigeration System Impaired by Chloro-Fluoro Refrigerants

Solar energy is a periodic unsteady heat source. In the utilization of solar energy, direct recovery at about 100°C is feasible and economical. In the solar driven ejector-absorption refrigeration cycle with re-absorption of the strong solution and pressure boost of the weak solution. High COP is obtained by increasing the efficiency of the absorber with the help of Ejectors (liquid - gas) Low pressure refrigerant vapour is injected and pressurized high pressure solution. Flow resistance is minimized. A small solution pump is used, in this system No moving parts, No Lubrication, Low maintenance and simple in operation. Working fluids is based on salt absorbent, low evaporation temperature and reduce the problem of crystallization. Working pairs used in the system is NH3 - H20 (or) NH3 - Lithium Nitrate.
