Described herein is a refrigeration pack and a method of providing same, comprising: providing a pumpable slurry comprising a frozen component and a liquid component, providing within the pumpable slurry a thickening agent to absorb some of the liquid component of the pumpable slurry, and to increase a viscosity of the pumpable slurry; providing a refrigeration pack housing; and, providing the pumpable slurry to the refrigeration pack housing.

A system for cooling a substance that includes a heat transfer device with a coolant contained within the heat transfer device. The coolant has a first phase change temperature such that when the coolant is cooled below a phase change temperature the coolant transitions from a liquid to a solid phase. The system further includes a substance that has a second phase change temperature. The substance is positioned in close proximity to the heat transfer device such that thermal energy is transferred away from the substance into the coolant. The coolant may repeatedly undergo a phase change with re-exposure to a temperature below the phase change temperature and the heat transfer device requires no other activation than cooling below the first phase change temperature to commence thermal energy transfer with the substance.

According to various aspects, exemplary embodiments are disclosed of chiller systems including thermoelectric modules, and corresponding control methods. In an exemplary embodiment, a compressor chiller system generally includes a refrigerant loop having a refrigerant fluid, a compressor connected in the refrigerant loop to compress the refrigerant fluid, and a condenser connected in the refrigerant loop to receive the compressed refrigerant fluid from the compressor and to condense the compressed refrigerant fluid. The system also includes a heat transfer component connected in the refrigerant loop to receive the condensed refrigerant fluid from the condenser, and a coolant loop having a coolant fluid. The heat transfer component is connected in the coolant loop to transfer heat from the coolant fluid to the condensed refrigerant fluid. The system further includes a thermoelectric module connected in the coolant loop. The thermoelectric module is adapted to transfer heat into and/or out of the coolant fluid.

A portable insulated container includes an outer shell and a temperature control pack. The portable insulated container also includes a first insert portion that fits inside the outer shell and a second insert portion that also fits inside the outer shell and is configured to engage with the first insert portion to form a plurality of insulated cavities including a temperature control pack cavity along with three or more separate bottle storage cavities. Each of the three or more bottle storage cavities is configured for receiving a bottle and each of the three or more bottle storage cavities is configured for receiving bottles of different sizes and shapes. Each of the three or more bottle storage cavities may also be equidistant from the temperature control pack cavity.

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 agains 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.

Provided is a cold insulation tool capable of easily producing ice slurry. The cold insulation tool includes an outer casing that is provided to accommodate a tubular storage container filled with a beverage, a heat exchange unit that is detachably provided in the outer casing, and a stimulating unit that increases a surface area of at least a part of a gas-liquid interface of the beverage, in which the heat exchange unit includes a heat-storage material having a predetermined melting point, and a filling portion that has an internal space for filling with the heat-storage material liquid-tightly, and the melting point of the heat-storage material is lower than 0.2 C.

The present invention provides a slushy cup capable of realizing quick heat exchange. The slushy cup capable of realizing quick heat exchange includes an inner core, an outer cup body, and a sealing connection sleeve sleeving the outer cup body, wherein the sealing connection sleeve stores a refrigerant in an interlayer in a sealing manner through multi-layer sealing, and convex ribs are distributed on an outer circumferential side wall of a main body portion of the inner core, thereby increasing a contact area of heat exchange and enhancing the strength of an outer wall of the inner core. Through full contact between the convex ribs on an outer surface of the inner core and the refrigerant, cold energy of the refrigerant in the interlayer is quickly conducted to a drink in the inner core to quickly cool the drink into a slushy drink.

Method and system for maintaining temperature-sensitive materials within a target temperature range for an extended time. In one embodiment, the system keeps materials within a temperature range of +2 C. to +8 C. and includes an insulated container, a product box, ice packs, and organic phase-change material (PCM) packs. The ice packs are preconditioned to a very low temperature, such as 20 C. The organic PCM packs do not require preconditioning and may be kept at room temperature. In use, the frozen ice packs and the warm organic PCM packs may be loaded into the insulated container, together with a payload in the product box. Preferably, the frozen ice packs are sandwiched between a pair of organic PCM packs on each face of the product box. The masses of ice and organic PCM are selected so that, upon thermal equilibration, the ice and organic PCM are within the target temperature range.
