Experimental Investigation and Analysis of Solar Refrigeration System

摘要

A solar cooling system consisting of parabolic trough collector array, absorption machine of 100 KW, cooling tower was studied under real time conditions. The system worked entirely with solar energy and produced cooling for 5h (under permanent regime) on a hot day. Cooling produced by this technology was absolutely CFC free and there was no production of CO2, during this process because we were not using the electricity from the thermal sources. Working and operation of the solar powered Li-Br-H_2O absorption systems was totally dependent upon the solar thermal (heat). This system was found more suitable for the countries where sunshine hours and summer session are longer i.e. near the equator. Efficiency parameter of the chiller that is co-efficient of performance was determined and analyzed that this system has highest cop up to 1.56 as compared with the single and double effect system. Cop of the solar powered was varying with the solar radiations. At high solar intensity temperature of the hot water goes maximum and produced the maximum cooling effect up to 1.7 depending upon the intensity and duration of the solar radiations.
