Abstract: A cold and/or heat accumulator with a plurality of carrier elements which are charged with a cold or heat storage medium, and with at least one heat exchanger which is designed to have a heat transfer medium flow through it in order to cause heat exchange between the cold or heat storage medium and the heat transfer medium. The at least one heat exchanger has a serpentine hollow section, and carrier elements are provided between the legs of the loops of the serpentine hollow section. Two heat exchangers can be provided with the loops of the serpentine hollow section one heat exchanger being interspersed with those of the serpentine hollow section of the other heat exchanger. Preferably, the carrier elements are made of a porous metal foam, and the inlet and outlet for the heat transfer medium are located together at a bottom area at one side of the accumulator.

Abstract: A cold and/or heat accumulator with a plurality of carrier elements (10) which are charged with a cold or heat storage medium, and with a heat exchanger (12) which is designed to have a heat transfer medium flow through it in order to cause heat exchange between the cold or heat storage medium and the heat transfer medium. The heat exchanger (12) has at least one serpentine hollow section (14), and at least at least one carrier element (10) is provided between the legs of at least some of the loops of the serpentine hollow section. In a process for producing the cold and/or heat accumulator, the height of the carrier elements is coordinated to a distance between the legs of the at least one loop such that, after a force-fit connection is formed between the serpentine hollow section and the carrier elements.

Abstract: Methods of extracting and removing hyperpolarized gas from a container include introducing an extraction fluid into the container to force the hyperpolarized gas out of an exit port. The hyperpolarized gas is forced out of the container separate and apart from the extraction fluid. Alternatively, if the fluid is a gas, a portion of the gas is mixed with the hyperpolarized gas to form a sterile mixed fluid product suitable for introduction to a patient. An additional method includes engaging a gas transfer source such as a syringe to a transport container and pulling a quantity of the hyperpolarized gas out of the container in a controlled manner. Another method includes introducing a quantity of liquid into a container and covering at least one predetermined internal surface or component with the liquid to mask the surfaces and keep the hyperpolarized gas away from the predetermined internal surface, thereby inhibiting any depolarizing affect from same.

Abstract: A refrigerator with at least one medium/low temperature-freezing compartment and a compression refrigeration system with a thermal storage, and a method of operating the refrigeration system with a thermal storage are provided. The refrigeration system includes a compressor, a condenser, a thermal storage, a medium/low temperature evaporator, a first expansion device, a second expansion device, a bypass line to bypass the second expansion device, a refrigerant valve to direct refrigerant flow after the thermal storage either to the bypass line or to the second expansion device, and control means to control temperature in the compartments, the compressor and the valve operations. The method comprises steps of charge and discharge of the thermal storage. During the thermal storage discharge refrigerant evaporates in the medium/low temperature evaporator providing refrigeration to the freezing compartment.

Abstract: A container for fast cooling of milk and its preservation and transportation at an optimal temperature (0.degree.-4.degree. C.) comprises a body (11) consisting of an internal recipient (12) defining a tank (13) for containing the milk and an intermediate shell (14) surrounding the internal recipient (12) and connected in a sealed manner therewith to define between the recipient (12) and the intermediate shell (14) a jacket (18) designed to contain liquid at a freezing temperature lower than a predetermined preservation temperature. The container is covered with an insulating external shell (20). Ducts (30) for circulation of the refrigerating fluid are arranged in the jacket (18). There can also be provided means (48,49,54) for the controlled input of milk up to thermal contact with the refrigerating walls of the recipient (12) and means (35) for mixing the milk in the tank (13) during cooling and preservation.

Abstract: A cooling tank for a water cooler, comprising a housing for holding water, having set therein a condensing coil which is uniformly arranged around the inner wall surface of said housing with one end connected to the expansion valve of said water cooler and an opposite end connected to the compressor of said water cooler for circulation of cooling medium, and a plurality of coil-shaped water pipes which are separately mounted in said housing with each two opposite ends respectively connected to an independent inlet valve and an independent outlet valve mounted on said housing at the outside. A plurality of reservoirs are separately connected to the inlet and outlet valves of each coil-shaped water pipes so that the liquid from each reservoir can be separately pumped into the coil-shaped water pipes for circulation through the cooling tank for cooling.

Abstract: A coolness storage air conditioner appliance in which water is frozen in chambers during protracted charging cycles by refrigeration apparatus of sufficiently low capacity to permit heat discharge into an interior air space and is melted during brief cooling cycles by air circulated through passageways in heat-transfer relation with the ice, the discharged circulated air thereby cooling the interior air space.

Abstract: The refrigeration system disclosed herein provides separate chilling and freezing compartments and operates in alternate phases. In the first phase, an evaporator which controls chilling compartment temperature also absorbs heat from a thermal mass through the change of phase of a liquid to a solid. In the second phase, this evaporator becomes a condenser for the operation of a second evaporator associated with the freezer component. During this second phase, the heat transfer is reversed, the fusion energy of the first phase is recaptured as melting energy in the second. Accordingly, heat is transferred from the second evaporator to the mass over a temperature differential which is less than that existing between the second evaporator and the environment.
