Summary

The physical behavior of the new refrigerant R723, an azeotropic mixture of 60% Ammonia and 40% Dimethyl Ether, was investigated for use in adsorption heat pumps and refrigeration systems. The potential use of this refrigerant blend in adsorption systems with components made of copper instead of stainless steel provides with a motive for experimental investigation. In this work the experimental results of an activated carbon – R723 pair generator are presented when operating with driving temperatures ranging from 100°C up to 170°C and condensing temperatures of 20°C and 35°C. By comparing the measured temperature of the refrigerant liquid in the receiver and the saturated temperature calculated from the measured pressure it is shown that the refrigerant R723 remains stable throughout the adsorption – desorption process even when operating at pressures as high as 16 bar.
