✦ Synopsis

AlmmacttThis paper presents a conceptual thermodynamic design and feasibility study of a dual mode absorption cycle with auxiliary heat exchanger. The system consists of two single stage absorption cycles connected through the condenser of the first stage with the generator of the second stage. The purpose of the auxiliary heat exchanger is to maintain the condenser (I) temperature suffufieotly high to operate the generator (2). A case study, using a single fluid pair HzO-LiBr in both the stages and two fluid pairs (H20-LiBr at first stage and NH3-LiNO3 at second stage) has been considered. It is found that the COP of the dual mode absorption cycle is higher than the single stage absorption cycle and the COP is lower for the two pair system in comparison to the single pair system. However, the former has the advantage of providing simultaneous refrigeration and air-conditioning.
