Solar cooling by solid absorption system.

Author(s) : GUKHOOL J.

Summary

A prototype designed for space cooling using monomethylamine and crystalline calcium chloride as the working fluid and solid absorbent, respectively, is shown to be a very attractive idea, particularly for tropical countries having ambient temperatures around 40 deg C. In spite of seemingly insurmountable difficulties in getting the system working, test runs yielded a promising low operating pressure of 380 kilopascals, compared to 1500 kilopascals for calcium chloride-ammonia and 550 kilopascals for lithium chloride-methylamine couples. A very low temperature of 6 deg C for the chilled water was attained, and a COP of 0.123 was found to compare well with those of calcium chloride-ammonia (0.18-0.32) and lithium chloride-methylamine (0.06-0.08). Decomposition of the complex compound calcium chloride-methylamine could be achieved with water around 70 deg C, a not so difficult task using solar energy.
