Abstract
In today`s era, two conventional methods for refrigeration are the compression system which uses huge amount of electricity to drive the compressor and other is the absorption system which is bulky and a bit difficult to handle. Hence, for providing a solution to the cooling needs designed a new system which works totally on solar energy using intermittent absorption principle which produces refrigeration effect for cooling and storing in both industry and domestic purposes. Working in the two phases where it absorbs the heat energy from sun during day phase to convert it into refrigeration effect during night phase. The system proves the theoretical cycle of solar intermittent vapor absorption cycle. This system excludes the moving parts in the conventional vapour absorption refrigeration system and has less maintenance. Working on the low heat input, i.e. it requires comparatively lower temperature to the generator is about 96oC which is easy to attain by parabolic trough. The cycle works in two phases producing the effect in 6 hours of operation. The amount of refrigeration effect is based on the maximum temperature of the generator. The maximum drop in the temperature at the evaporator in the present work is estimated to be 4oC.
