| Research Abstract |
The conventional absorption refrigerators uses H_2O-LiBr as an absorption solution, so taht a heat source with a temperature of around 110 degree C or more is required. Furthermore, a conventional LiBr-H_2O absorption refrigerator is difficult to manufacture brine under the freezing point 0 degree C, since the refrigerant is water. A new absorption refrigerator to manufacture the cold heat below zero degree C, and to be operated by a below 100 degree C heat source, such as the solar collector or plant waste heat, is developed, using H_2O-LiBr-1,4-dioxane as absorption solution. Various properties are studied experimentally. And new absorption refrigerant cycle which can manufacture the sub freezing cold heat driven by the low temperature heat is developed.
