| Abstract: | A new absorption cycle, using heat as the energy source, was proposed to produce refrigeration. This proposed cycle, referred to as the single-effect regenerative absorption cycle or cycle 1R, has a performance much superior to the well-known basic absorption cycle, namely: the coefficient of performance (COP) is higher at higher input temperatures and the ''cut-off'' input temperature is very much lower. The cycle 1R operates with a multistage boiler and a multistage absorber in such a way that each stage of the heat input and heat rejection processes of the cycle occurs essentially at constant temperature rather than at constant pressure. The greatest part of the high pressure refrigerant vapor subsequently condensed is generated in an adiabatic multi-section regenerator rather than in the boiler (or the generator). The greatest part of the heat necessary to generate the high pressure refrigerant vapor comes from the absorption of the evaporator vapor by the very weak solution leaving the boiler. This absorption process occurs in the regenerator. Because the regenerator is adiabatic, the cycle receives and rejects heat at essentially constant temperatures. Therefore, the COP of the cycle approaches the Carnot COP. |
