Summary

A heat source at temperatures not higher than 80 deg C was used to simulate the heat input to an absorption refrigerator from a solar pond. A laboratory model of an absorption refrigerator, using an ammonia-water solution at 52% concentration by weight, was operated intermittently using this heat source. Generation temperatures as high as 73 deg C and evaporation temperatures as low as -2 deg C were obtained. Tap water was used to remove the heat generated from the condensation of the ammonia vapour and the absorption of the refrigerant in the water. The temperature of the tap water was near the ambient laboratory temperature of 28 deg C. The COP for this unit working under such conditions was in the range 0.24-0.28.
