Review on Lithium-Bromide/Water Vapor Absorption Air-Conditioning System using Solar Energy

This paper reviews past efforts in this field of solar operated air-conditioning systems using the absorption pair of lithium bromide/water. A number of attempts have been made by researchers to improve the performance of the solar air-conditioning system. Lithium-bromide/water system is more effective than any other pair of absorber-refrigerant. It is seen that the inlet temperature of generator is the most important parameter for optimize the design and fabrication of a solar operated air-conditioning system. While system design, collector choice and arrangement of system are other impacting factors for the system operation. The parabolic through collector is very effective for reach the sufficient generator temperature. In this paper we analyse double stage vapor absorption cycle is more effective than single stage absorption cycle. Solar energy applications in for domestic hot water, space heating and cooling have been considered very effective. The ultimate goal of this study in the long term would ideally be to reduce the consumption of electricity used for air-conditioning system.
