Abstract
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.
Claims11
An intermittent operation based continuous absorption system comprising:
- a plurality of generator-absorber units, each of the plurality of generator-absorber units including a shell and a heat exchanger disposed within the shell;
- a heat recovery circuit including a transfer pump to conduct heat recovery;
- a solar collection circuit including a solar collector to collect solar thermal energy;
- a heat rejection circuit including a heat rejection unit to reject heat;
- and
- a generation circuit including a vapor-liquid heat exchanger unit and an evaporator to provide refrigeration to a cooling load,
- wherein each of the heat exchangers of the plurality of generator-absorber units include an internal passage that is in selective fluid communication with the solar collection circuit, the heat rejection circuit, and the heat recovery circuit, and
- wherein each of the shells of the plurality of generator-absorber units is in selective fluid communication with the generation circuit.
