An intermittent operation based continuous absorption system (IOBCAS) which supports cooling effect during the daytime without the use of a solution pump is provided. The IOBCAS may utilize an isochoric process for pressurization of the system and the system may include a plurality of generator-absorber units that intermittently operate in succession to provide a continuous refrigeration cooling effect during the daytime. The system of the present disclosure enables the plurality of generator-absorber units to switch between a generation, absorption, and heat recovery mode of operation to provide cooling effect during the daytime which a higher coefficient of performance compared with conventional intermittent system.

Continuous adsorption cooling system with air-cooled heat rejection unit

Solar powered intermittent operation based continuous absorption system

An economizer for a solar powered intermittent absorption refrigeration system improves the coefficient of performance of the refrigeration system. The economizer recovers waste energy rejected by an absorber during an absorption process, stores the waste energy, and supplies the waste energy to a generator during a generation process, thereby reducing the amount of energy input needed to operate the system.

Economizer for an intermittent absorption refrigeration system

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.
