4621 Saturation Characteristics of a Working Fluid for a Absorption Refrigerator driven by a Low Temperature Heat Source

Abstract

It is well known that adding 1,4-dioxane into H_2O affects the hydrogen bond of H_2O, the cluster configuration is altered, and the characteristics of H_2O change. Paying attention to this point, saturation characteristics of LiBr-H_2O-1,4-dioxane, which is used as a working fluid of an absorption refrigerator, are studied experimentally. Results show that the saturation temperature of the present solution is lower than conventional solution. Therefore, it is proved that if the present solution is used as the working fluid, a low temperature waste heat of less than 100℃ can be used to manufacture the cold brine for an air-conditioner.
