In recent years, the absorption refrigerant cycle using H_2O -LiBr solvent as working fluid has widely been used in Japan, as a standpoint of energy shortage. However, This type of air conditioner and chiller is difficult to refrigerate because of the properties of the working fluid. Against this working fluid pair, there' s the absorption refrigerant cycle using NH_3-H_2O solvent as working fluid. This cycle is available to apply the system for various uses. But this type has not popularized for regulation in low in Japan so far. As a result, in this study TFE (2, 2-, 2-Trifluroethanol)/NMP (n-Methy-2-Pyrolidone) was picked out as a working fluid, and the evaporation heat transfer coefficients are measured to grasp a thermal characteristic of TFE/NMP mixtures in a capillary wick, that was applied for the proposed effective absorption cycle using a capillary wick in the generator.
