Thermal recuperation methods, systems, and devices
View Patent ↗Thermal recuperation methods, systems, and devices are provided. The methods, systems, and/or devices may provide for: introducing a first fluid into at least a portion of a tank containing a solid; exchanging heat between the solid contained within the tank and the first fluid as the first fluid passes at least around or through the solid; extracting the heated first fluid from at least the portion of the tank containing the solid; and/or passing the heated first fluid with respect to a heat exchanger thermally coupled with a second fluid. The heated first fluid may be cooled as it passes with respect to the heat exchanger and heat may be thermally recuperated between the solid and the second fluid.
1. A method of thermally recuperating heat comprising:
introducing a first fluid into a portion of a tank containing ice, wherein the first fluid passes through a vertically-oriented injector positioned within the tank containing the ice to introduce the first fluid into the tank containing the ice;
exchanging heat between the ice contained within the tank and the first fluid as the first fluid makes direct contact with the ice and moves up through the tank containing the ice;
extracting the first fluid from the tank containing the ice;
melting at least a portion of the ice through combining at least the portion of the ice with a freeze point suppressant in a portion of the tank containing the portion of ice to produce a second fluid after the first fluid makes direct contact with the portion of the ice; and
passing the first fluid, after being extracted from the tank containing the ice, through a heat exchanger thermally coupled with the second fluid, wherein the first fluid is cooled as it passes through the heat exchanger.
2. The method of claim 1 , further comprising recirculating the first fluid through the tank after it has passed with respect to the heat exchanger.
3. The method of claim 1 , further comprising utilizing at least a pump, a compressor, or a blower to facilitate at least the introducing or the extracting of the first fluid.
4. The method of claim 1 , wherein the first fluid comprises an inert fluid.
5. The method of claim 4 , wherein the inert fluid comprises air.
6. The method of claim 1 , wherein exchanging heat between the ice contained within the tank and the first fluid as the first fluid makes direct contact with the ice heats the first fluid.
7. The method of claim 1 , wherein the heat exchanger thermally coupled with the second fluid is configured such that the second fluid passes through the heat exchanger.
