| Abstract: | In this paper, TFE-BMIm]Br] was selected as novel working fluid for absorption cooling cycle. The model of thermophysics properties of TFE-BMIm]Br] was proposed, and the simulation of the parallel double effect absorption cooling cycle was set up. The effects of efficiency of solution heat exchanger, evaporation temperature, absorption temperature and generation temperature on the performance, solution circulating ratio and operation pressure of four cycles were analyzed. The feasible operation scope an... |
