Abstract: Thermo-chemical recuperation systems, devices, and methods are provided in accordance with various embodiments. Embodiments may generally relate to the field of refrigeration and/or heat pumping. Within that field, some embodiments apply to the recuperation or recapturing of both thermal and chemical potential in a freeze point suppression cycle. Some embodiments include a method and/or system of thermo-chemical recuperation that includes creating a flow of ice and flowing a brine against the flow of the ice. Some embodiments manage the thermal and chemical potentials by mixing a dilute brine stream exiting an ice mixing vessel with an ice stream before it enters the ice mixing vessel. By controlling this mixing in a counter-flow or step-wise cross flow manner with sufficient steps, both the thermal and chemical potential of the dilute bine stream may be recuperated.

Some embodiments may integrate with vapor compression heat pumps in industrial, commercial, and/or residential applications. Some embodiments include a method that may include at least: removing a first heat from a vapor compression cycle; utilizing the first removed heat from the vapor compression cycle to drive a thermally driven heat pump; or removing a second heat from the vapor compression cycle utilizing the thermally driven heat pump to reduce a temperature of a refrigerant of the vapor compression cycle below an ambient temperature.

Abstract: Methods, systems, and devices for freeze point suppression cycle control are provided in accordance with various embodiments. For example, some embodiments include a method of freeze point suppression cycle control.

Abstract: Methods, systems, and device for solidification and/or solid production, such as ice production, are provided. For example, a method of solid production includes contacting a first fluid with a second fluid to facilitate solidifying the second fluid; the first fluid and the second fluid are immiscible with respect to each other. The method includes solidifying the second fluid. A solid production system includes a first fluid and a second fluid; the first fluid and the second fluid are immiscible with respect to each other. The system includes one or more surfaces configured to contact the first fluid and the second fluid with each other and to form one or more solids from the second fluid.

Abstract: Methods, systems, and devices are provided for thermal enhancement. Thermal enhancement may include absorbing heat from one or more devices. In some cases, this may improve the efficiency of the one or more devices. In general, a phase transition may be induced in a storage material. The storage material may be combined with a freeze point suppressant in order to reduce its melt point. The mixture may be used to boost the performance of device, such as an electrical generator, a heat engine, a refrigerator, and/or a freezer. The freeze point suppressant and storage material may be separated. By delaying the periods between each stage by prescribed amounts, the methods, systems, and devices may be able to shift the availability of electricity to the user and/or otherwise boost a device at different times in some cases.

Abstract: 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.
