The impact of ambient temperature on lithium-bromide/water absorption machine performance

During this decade, primarily due to escalating energy costs and environmental aspects, cogeneration has become popular. Absorption heat recovery offers an excellent alternative to utilising what previously amounted to waste heat. In this study the influence of ambient temperature on the generator temperature, concentration of strong solution, flow ratio of the solution and on the evaporator temperature attainable for air-conditioning purposes of a lithium bromide/water absorption unit has been investigated. It has been shown that an increase in the ambient temperature causes an increase in the generator temperature. Finally, the effect of flow ratio on the generator temperature has been given.
