Patent number: 11709023Abstract: The present invention discloses a heat exchanger system for thermochemical storage and release. The system comprises a thermal exchange circuit with a heat exchanger fluid, the circuit further in thermal connection with a thermochemical module. The thermochemical module comprises a thermochemical material that stores and releases heat by a thermochemical exchange process under release or binding of a sorbate. The thermochemical module comprises a compartment structure that compartments the thermochemical material and further comprises a channel structure. This provides an exchange of the sorbate and the thermochemical material via the channel structure to the compartment structure. A method for the preparation of the compartment structure is also described. In this method, the thermochemical material is brought in a liquid phase and inserted in the compartment structure, while keeping the channel structure free from the liquid phase; and subsequently dried.Type: GrantFiled: March 29, 2018Date of Patent: July 25, 2023Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventors: Ruud Cuypers, Cornelis Petrus Marcus Roelands, Adriaan Jan de Jong, Hendrik Pieter Oversloot, Laurens Daniel van Vliet

Publication number: 20230056787Abstract: The invention relates to a sensible heat storage apparatus that comprises a core material that can be heated to a high temperature while it has been placed in a heat transfer fluid that absorbs essentially all the heat that is lost by any heat leakages from the core material. Accordingly, there is a very low, or almost absent overall heat loss, even though the sensible heat storage apparatus can store heat at a very high temperature. The gist of the invention is further that the high amount of heat can gradually be transferred to the HTF, which heat can in turn be put to use for domestic applications (e.g. domestic hot water and/or space heating) or for steam generation.Type: ApplicationFiled: February 10, 2021Publication date: February 23, 2023Inventors: Martin Mohana, Pavol Bodis, Laurens Daniël Van Vliet, Ruud Cuypers
