A chest insert for a freezer is disclosed. The chest insert is placed inside a freezer and food is placed inside the chest insert. Several sides of the chest insert comprise a gap which is partially filled with a refrigerant gel. These gaps are slanted such that the gel can expand into a wider gap as it expands while freezing, lessening the risk of uneven freezing causing the refrigerant gel to press against the walls of the chest insert. The use of the disclosed subject matter reduces freezer burn by stabilizing humidity. Further, the chest insert maintains the temperature inside the chest insert for extended periods if the freezer fails or the power to the freezer is interrupted.

Dry ice cooling systems and methods of making dry ice cooling systems are disclosed. According to embodiments, dry ice cooling systems include a compression container including compressed liquid carbon dioxide. The dry ice cooling systems include a dry ice container coupled to the compression container to receive the liquid carbon dioxide and house dry ice as it forms. The dry ice container includes a liquid coolant. Further, the dry ice cooling system includes a heat exchanger to couple a heat-generating source to the dry ice container.

A cold storage material and a cold storage pack are provided where a single cooling medium (cold insulation pack) containing a cold storage material having a plurality of melting points can keep an object at a low temperature that is suited to a situation. The cold storage material changes phase at a prescribed temperature and contains: water; a base compound containing a quaternary ammonium salt that forms a semi-clathrate hydrate; and a supercooling inhibitor that suppresses supercooling, wherein the cold storage material has one or more melting points depending on a temperature range in which the cold storage material has been frozen. These features allow the user to set the melting point of the cold storage material as he/she wants, by properly changing the freezing temperature for intended usage

An insulated container for storing or shipping bottles includes a body and a lid. The body has a shell and an insert portion formed from an insulating material. The lid also has a shell and an insert portion formed from the insulating which meets the insert portion of the body to form cavities. The cavities include a temperature control pack cavity and four or more separate bottle storage cavities distributed around the temperature control pack cavity. Each of the bottle storage cavities is configured for receiving a bottle from among three or more different bottle types. Each of the bottle types has a different shape and/or size than each of the other bottle types. Each of the bottle storage cavities includes at least three bottle stop features on one or more internal surfaces. Each bottle stop feature is associated with a different one of the three or more bottle types.

An insulated cold pack for cooling a product, the cold pack including a viscous cooling agent that may serve as a plant fertilizer when discarded. The cooling agent encapsulated in at least one sealed flexible walled package, the one or more flexible walled packages located on the first side of the insulated cold pack. In addition, the cold pack includes biodegradable loose-fill insulation covering the second side of the insulated cold pack. An encapsulating barrier surrounds both the viscous cooling agent on the first side of the insulated cold pack as well as the loose-fill insulation on the second side. The loose-fill insulation secured in position within the encapsulating barrier and the insulation positioned in contact with the product or optionally closely spaced from the product to be cooled.

A system for manipulating heat transfer includes a thermal sleeve, a vessel and a lid. The thermal sleeve includes a first material and a second material. The vessel includes an outer wall disposed about an inner wall, the inner wall defining a reservoir configured to contain a liquid and the inner wall and outer wall defining a gap therebetween. The lid is configured to open to facilitate adding of the liquid to the reservoir. The thermal sleeve is configured to be positioned within the gap.

Provided are a latent heat storage material having a melting point within a prescribed temperature range; a latent heat. The latent heat storage material includes a compound (A) represented by a formula (A), an inorganic salt (B) represented by a formula (B) and composed of a cation of an alkali metal and an anion of the same element as the anion of the quaternary alkyl salt, and water. The compound (A) is a material that forms a clathrate hydrate together with the water, the composition ratio of the compound (A) and water is a composition ratio that gives a congruent melting point of the clathrate hydrate, and the molar ratio of the inorganic salt (B) to the compound (A) is 0.1 or more and 10 or less.

A gel-pack has a plurality of self-contained components organized as layers in an interior chamber of the gel-pack. Each layer may be inserted into, and removed from, the interior chamber individually. The components include a solid-state gel layer that stores thermal energy, a first radiant energy barrier that prevents the transfer of thermal energy radiating from an exterior of the gel-pack into the solid-state gel layer, and a second radiant energy barrier that reflects the thermal energy radiating from the user's body into the solid-state gel layer.
