Abstract
A solar powered intermittent absorption refrigeration system utilizes helical coil heat exchangers for generation, absorption, dephlegmation, condensation and heat recovery. The thermo-siphon effect is used to supply and reject heat from the system, to recover and utilize heat from a waste energy unit, to reject heat of absorption, and to pressurize and depressurize the system. The system produces ice blocks during the nighttime without any requirement of electrical energy for the operation of the system.
