The invention relates to a system (1) and a method for pasteurizing foods packed in closed containers (2). The containers (2) are supplied with a processing liquid (11) in at least one heating zone (5,6), at least one pasteurization zone (7, 8), and at least one cooling zone (9, 10). In order to cool and heat the processing liquid (11) as needed, a coolant (23) is cooled by means of a heat pump (22) in a cooling circuit (20), and a heating medium (33) is heated by means of the heat pump (22) in a heating circuit via a respective heat exchanger (19, 30) in each case. In order to provide cooling energy, the cooled coolant (23) is introduced into a lower end region of a cold buffer store (24), and in order to provide heating energy the heated heating medium (33) is introduced into an upper end region of a heat buffer store (35).

A system includes a heat-pump circuit and a heating-fluid circuit. The heat-pump circuit includes a compressor and a first condenser conduit. The heating-fluid circuit includes first, second, and third flow-paths. The third flow-path selectively communicates with the first and second flow-paths. The first flow-path includes a first valve. The first valve moves between an open position allowing fluid flow through the first flow-path and a closed position restricting fluid flow through the first flow-path. The second flow-path includes a second condenser conduit and a second valve. When the second valve is open, fluid flows through the second flow-path. In the closed position, the second valve restricts fluid flow through the second flow-path. The third flow-path includes a heat exchanger receiving fluid from the first flow-path when the first valve is in the open position and receiving fluid from the second flow-path when the second valve is in the open position.

A heat transfer composition includes: (i) trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)); (ii) a second component selected from difluoromethane (R-32), propene (R-1270), propane (R290) and mixtures thereof; (iii) a third component selected from pentafluoroethane (R-125), 1,1,1,2-tetrafluoroethane (R-34a), and mixtures thereof; and optionally (iv) a fourth component selected from fluoroethane (R-161), 1,1-difluoroethane (R-152a) and mixtures thereof.

Provided is a cold storage unit that has a high cold storage capacity, does not generate carbon dioxide, and enables recycling of the cold source. Also provided are a moving body and an ice slurry supply system. In the cold storage unit, a casing that defines a cold storage space has a heat insulating structure, a partition wall that faces the casing is provided at least at a top portion of the cold storage space, and a gap between the casing and the partition wall is filled with an ice slurry that is a mixture of brine and flake ice acquired by freezing the brine. In addition, it is possible to provide a supply port for supplying the ice slurry into the gap and a discharge port for discharging the ice slurry from the gap.

A cooler insert for placement into a portable hard cooler or ice chest for separating sandwiches, lunch meats, cheese, vegetables, and the like, and drinks from the materials used to cool these items, is described. Many commercially available portable coolers have rectangular-shaped cooling volumes with at least two of the opposing walls forming a horizontal ledge inside the cooling volume parallel to and below the opening thereof upon which the present cooler insert is supported. The present cooler insert includes three adjacent chambers, a first chamber for containing food items to be cooled, a second chamber for containing clean ice for use for cooling drinks; and a third chamber, having cylindrically-shaped compartments tapered toward the bottom, for holding cans or bottles. Bottom portions of the first two chambers may be formed using aluminum or other conductive metal plates covered with plastic, or using uncoated metal plates for improving conduction to the cooler insert from the cooler. The open top portions of the first and second chambers may be covered with a removable plastic or metal cover, which may also be used as a cutting board, when attached to the side of the cooler.

The present application is directed to a reusable, sealable pouch to hold ice, which is used in food coolers and other applications. Also described herein in method of manufacturing the pouch and a system of the pouch and a cooler.

A heat pump includes a condenser for condensing compressed working vapor, a gas trap coupled to the condenser via a foreign gas feed inlet and including: a housing having a foreign gas feed entrance, a working liquid feed inlet within the housing; a working liquid discharge outlet within the housing, and a pump for pumping off gas from the housing, wherein the housing, the working liquid feed inlet and the working liquid discharge outlet are configured such that during operation, a working liquid flow takes place, within the housing, from the working liquid feed inlet to the working liquid discharge outlet, and wherein the working liquid feed inlet is coupled to the heat pump so as to direct, during operation of the heat pump, working liquid which is colder than a working liquid within the condenser.

A dynamic packing system places one or more perishable items into a shipping container and dispenses thermal control components therein. There is a data processor and a database including one or more order data set each defined at least by an itemized list of purchased perishable items and an order shipment destination address. A network interface is connected to the data processor, and weather data is retrieved over the network interface from a remote source. A dispenser controlled by the data processor positions a specific amount of a thermal control component in the shipping container. The specific amount is based upon an evaluation of one or more temperature values corresponding to the weather data along a transport route of the shipping container.

A knockdown cooler with a number of removable chilling panels that cool an interior cavity of the cooler without exposing the contents therein to contact with unhygienic ice or water is provided. A collapsible storage member is positioned atop one or more structural support members to suspend the storage member in the chilling cavity, providing exposure to prolonged cooling impetus, a duration that may be prolonged if desired by removing and replacing one or more of the chilling panels without disrupting the contents of the cooler. A method of cooling items such as food, beverages, or the like without exposing the same to unhygienic ice or water in a knockdown cooler that can be assembled or disassembled without tools, mechanical fasteners, or adhesives is also provided.

A heat transfer composition includes: (i) trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)); (ii) a second component selected from difluoromethane (R-32), propene (R-1270), propane (R290) and mixtures thereof; (iii) a third component selected from pentafluoroethane (R-125), 1,1,1,2-tetraflueroethane (R-34a), and mixtures thereof; and optionally (iv) a fourth component selected from fluoroethane (R-161), 1,1-difluoroethane (R-152a) and mixtures thereof.
