Solar Air Conditioning System with ETC & LiBr Pair

Solar based absorption systems are used to reduce the electricity load due to use of compressors. Various absorption pairs have been tried for space cooling applications by using different solar heat inputs. The NH3- H2O based absorption system requires operating temperature ranging 120° to 150°, and needs concentrators with tracking ,attracting higher values ,however the Li-Br-H2o vapour absorption systems can operate at lower temperatures and can use FPC or ETC solar Water Heating systems as generators. This will also have low cost and low maintenance in near future. This research work has tried single effect 1 KW, LiBr-H2O absorption with evacuated tube solar collector. This system is tested and COPs are compared with standard vapour absorption SAC systems.
