“…Lin et al [34] also coupled a commercially available diffusion absorption refrigerator (DAR) with the exhaust of a diesel engine and concluded that the waste heat from the exhaust of the diesel engine was sufficient to drive the DAR only when the engine load was greater than 50%. The diesel engine employed by them was a Lister-Petter T series 9.5 kW diesel engine which was air cooled.…”

“…The regenerating unit of the VARC can be operated by low grade heat from a variety of thermal sources including solar collectors, waste process heat from an exhaust and hot water or steam generating processes. Biomass solid fuels can be used to provide the required energy via the production of hot water [17]. The quantity of biomass required to operate a VARC for a given load is estimated based on the calorific value of the species.…”

Abstract:The impact of vapour compression refrigeration is the main push for scientists to find an alternative sustainable technology. Vapour absorption is an ideal technology which makes use of waste heat or renewable heat, such as biomass, to drive absorption chillers from medium to large applications. In this paper, the aim was to investigate the feasibility of a biomass driven aqua-ammonia absorption system. An estimation of the solid biomass fuel quantity required to provide heat for the operation of a vapour absorption refrigeration cycle (VARC) is presented; the quantity of biomass required depends on the fuel density and the efficiency of the combustion and heat transfer systems. A single-stage aqua-ammonia refrigeration system analysis routine was developed to evaluate the system performance and ascertain the rate of energy transfer required to operate the system, and hence, the biomass quantity needed. In conclusion, this study demonstrated the results of the performance of a computational model of an aqua-ammonia system under a range of parameters. The model showed good agreement with published experimental data.

“…The experimental result showed that automobile exhaust temperature above 200 o Ccan act as the heating source of diffusion absorption refrigeration system. Automobile load less than 25%, no cooling effect due to automobile exhaust temperature less than 200 o C.When automobile load is 50%, 75% and 100%, diffusion absorption refrigerator can operate normally due to exhaust temperature greater than 200 o C. The result shows that automobile load is 75% has the maximum Coefficient of Performance, the minimum temperature difference of evaporator inlet and outlet, best system performance [8].…”

Compared with the gas-compressed refrigeration system, the diffusion absorption refrigeration cycle has no moving part and the associated noise and vibration. It can be operated without any electric input and driven by various energy sources, has no the problem of the substitute of CFC, furthermore it has positive significance in energy conservation, off peak, environmental protection, and promoting the use of gas. So it has broad application prospects as a kind of absorption refrigeration mode. In the development of diffusion absorption refrigeration technology, the performance of diffusion absorption refrigeration system has been improved and enhanced continuously. The paper presents and discusses the recent research progress of diffusion absorption refrigeration which contains design of bubble pump, adjustment and optimization of operation parameters, utilization of low-grade thermal energy and selection of working medium. The research direction of diffusion absorption refrigeration in the future is suggested.
