摘要：

A theoretical analysis of the coefficient of performance was undertaken to examine the performance characteristics of the water-lithium bromide-zinc chloride-calcium bromide system (1.0:1.0:0.13 by mass, respectively). The coefficient of performance for absorption refrigerating machines, absorption heat pumps and absorption heat transformers was calculated using the enthalpies at various temperatures, pressures and absorbent concentrations. The performance characteristics of this system were compared with that of the water-lithium bromide system and that of the other systems using water, methanol and ammonia as working media. This system was found to be suitable for an air-cooled single-stage absorption refrigerating machine, a single-stage, high temperature double-effect absorption heat pump and a two-stage absorption heat transformer. © 1990.
