Method for operating an absorption refrigeration unit as well as an absorption refrigeration unit

摘要

The operating system has ammonia used as the working medium, separated out from a rich ammonia soln. upon continuous supply of heat energy and restored to the liquid state upon heat extraction from a refrigerated space, with absorption by the ammonia soln. The heat energy is regulated in dependence on the detected temp variations of the refrigerated space relative to a required temp, using an electronic regulator employing a fuzzy logic.
