Theoretical and experimental evaluation of an indirect-fired GAX cycle cooling system

Analysis of internal heat recovery capability in air-cooled indirect fired GAX-based absorption chiller in part-load operation

“…Internal heat recovered by the SolutionCooled absorber follows a similar pattern, as indicated in Ref. [ 47 ]. Furthermore, the results suggest that the contribution of the generator to internal heat recovery is predominant when ΔP val1 increases, shifting the balance in favour of the generator over the SolutionCooled absorber.…”

“…Velázquez et al [ 13 ] propose a methodological analysis of an AirCooled absorption system for air conditioning purposes, which does not include the recovery of heat from the economiser and the recovery of heat from rectification. Gomez et al [ 14 ] reported the experimental evaluation of a GAX-based cycle for air conditioning purposes. Saghiruddin et al [ 15 ] carried out an economic analysis using a heat recovery absorber, reporting an increase of 20–30% in the performance of an ammonia water chiller, in addition to a 25% reduction in energy cost.…”

Experimental verification of the variable effect absorption refrigeration cycle

“…Among these cycles, only GAX (Generator Absorber heat eXchange) cycle has been studied experimentally [20]. Novel cycles using LiBr-water as working pairs are seldom researched experimentally.…”

Solar sorption cooling systems for residential applications: Options and guidelines

“…Fig. 6 shows a schematic of the working principle of the single effect ammonia/water absorption chillers, without GAX cycle (a) and with GAX cycle (b) (Gó mez et al, 2008).…”
