The present disclosure provides a drinking liquid cooling system comprising: a first cooler configured to cool drinking liquid; a second cooler configured to allow the drinking liquid from the first cooler to have a pre-defined temperature; and a drinking liquid guider configured to guide the drinking liquid via the first cooler and, then, via the second cooler and, then, to allow the drinking liquid to be discharged.

Embodiments of the present disclosure are directed toward systems and method for cooling a refrigerant flow of a refrigerant circuit with a cool water flow from a cool water storage to generate a warm water flow and to cool the refrigerant flow by a subcooling temperature difference, flowing the warm water flow to the cool water storage, and thermally isolating the warm water flow from the cool water flow in the cool water storage.

The invention provides, in some aspects, a thermal energy storage and retrieval system with a cavity containing a working fluid and a heat transfer surface disposed in the cavity transverse to a gravity field and in thermal coupling with an ice that is formed from and floating in the working fluid. The heat transfer surface transfers to that ice heat from a heat transfer medium that is thermally coupled to the heat transfer surface. According to aspects of the invention in which the ice is less dense than the working fluid, the heat transfer surface is disposed above (with respect to the gravity field) a region of the cavity where that ice is formed or inlet. According to aspects of the invention in which the ice is more dense than the working fluid, the heat transfer surface is disposed below that region.

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.

A storage unit comprises a casing defining an interior space for holding at least one item, a thermal element lining an interior surface of at least one side of the casing, and at least one thermal battery thermally coupled to the thermal element.

Secondary loop air conditioning and heat pump systems include a reservoir with a capsule holding a phase change material.

A dynamic temperature regulating device is for use in association with a temperature-controlled container. The dynamic temperature regulating device includes at least one heat source, at least one heat sink, a heat transfer medium and a control system. At least one of the heat source and the heat sink is a PCM (phase change material). The heat transfer medium is in thermal communication with and operably connected to the at least one heat source and the at least one heat sink. The control system is for controlling the selective thermal communication with the at least one heat source and with the at least one heat sink to regulate the temperature of the temperature-controlled container. A detachable PCM contained volumes includes a sealed housing, a phase change material and a heat transfer medium and functions as a PCM thermal energy storage volume.

A temperature controlled container includes a case which has a storage space formed therein; a thermoelectric element; a heat transfer body in communication with the thermoelectric element and facing the storage space. The heat transfer body includes a heat transfer case which has an enclosed space formed therein and is wider than the thermoelectric element, and includes a portion facing the thermoelectric element; a phase change material which is accommodated in the enclosed space; and a heat transfer body which is disposed in the heat transfer case so as to be positioned in the enclosed space. The heat transfer body has a first body portion which is in communication with the portion of the heat transfer case facing the thermoelectric element and a second body portion, and the first body portion in communication with the second body portion.

A gel pack kit for keeping beverage bottles cool during transport includes a plurality of gel pack parts. The parts include notches allowing the parts to be attached perpendicular to one another and assembled into a gel pack divider. The divider includes a plurality of bottle cooling areas being the spaces between the adjacent gel packs in the assembled divider structure. A method of utilizing the gel pack divider kit to keep beverage bottles cool during transport includes assembling the gel pack kit to form the gel pack divider and then refrigerating the assembled divider. After purchasing bottled beverages such as multiple bottles of wine in a box, an original cardboard divider provided in the box is removed and replaced with the chilled, assembled gel pack divider. The bottles sit in the bottle cooling areas and the gel pack divider provides a cooling effect during transport in the original box.
