G0601-4-4 Properties of the refrigerant of the absorption refrigerator manufacturing the cold heat below zero degree C

Abstract

A conventional absorption refrigerator uses H_2O-LiBr as an absorption solution. It needs a heat source with a temperature of around 110℃ or more for driving energy. Furthermore, it is difficult to manufacture the brine under the freezing point of water, since the refrigerant is water. The new absorption refrigerator which can manufacture the cold heat below zero degree C and can be driven by the heat source of the temperature below the boiling temperature of water is developed by using H_2O-LiBr-1,4-dioxane as the working fliud. This paper describes the properties of the new working fluid which are needed to design the new cycle of the absorption refrigerator.
