An experimental investigation into the integration of a jet-pump refrigeration cycle and a novel jet-spay thermal ice storage system

This paper describes and evaluates the results of an experimental investigation in to a novel thermally activated jet-pump refrigerator and a jet spay thermal ice storage system, in which a steam driven jet-pump is used to create a vacuum pressure in a hermetic vessel into which water is sprayed through a nozzle. The effect creates ice in the vessel. It is envisaged that the ice is used as a coolth storage medium for cooling building ventilation air. It is envisaged that the jet-pump refrigerator would be powered by solar heat and so the coolth store would help to level out the peaks and troughs in output experienced by solar powered devices. The paper describes the proposed system and the experimental apparatus and discusses the results.
