Performance analysis was made for the absorption refrigeration cycle using TFE/NMP as a working fluid. In the calculation the steady states model, and the separation and mixture of refrigerant model were constructed. The experimental equipment of the absorption refrigeration cycle was also manufactured. The calculation model and the experimental equipment consisted of the generator, the condenser, the evaporator, the absorber, the partial condenser, the rectifier, the reservoir, the heat recovery heat exchanger, the solution pump and the expansion valve. The reservoir was used to store the liquid refrigerant for changing the solution concentration in the cycle. The calculation and experimental results showed the agreement at the lower generation temperature, but presented the opposite trend because of the influence of the heat release in the partial condenser. The calculation and experimental results showed the good agreement for the separation and mixture of refrigerant process. In results, it was found that this absorption refrigeration cycle using TFE/NMP as a working fluid had possibility to utilize recovering the wide range waste heat to energy.
