The absorption refrigerators with H_2O/LiBr working fluid pair are popular here in Japan for air conditioners in office buildings and public institutions. But H_2O/LiBr working fluid pair is not able to work in the condition of under 0℃. And further they have problems of crystallization of the solution when the solution becomes higher concentration. On the other hand, TFE/NMP working fluid pair has the advantage of working under atmospheric pressure, driving the refrigeration cycle under 0℃ for heat pump and no-crystallization of solution in all solution concentration range. Therefore this working fluid pair has possibility of using wide solution concentration and heat source temperature range. In this study the experimental equipment of TFE/NMP absorption refrigerantion cycle was manufactured and the fundamental characteristics of this absorption cycle were experimentally investigated changing the heat loads to the generator and the strong solution flow rates.
