  • Patent number: 8056357
    Abstract: A method and a device for better utilizing latent cold in a cold producing material used for producing and upholding a pre-determined temperature inside a transport container or the like, where dry ice or a similar first phase change material having very low sublimation temperature is utilized. Inside the transport container is arranged a receptacle for such low sublimation temperature phase converting material, the said receptacle being provided with an enclosure having cavities for a second phase change material having a considerably higher melting point, the said cavities of the receptacle at least partially enclosing the inside of the receptacle, in which the converting material having the essentially lower melting point is received.

  • Publication number: 20030136133
    Abstract: The invention relates to a liquid cooling system for machine components of production machines of the tobacco-processing industry. The object of the described cooling system is to improve the conveyance of liquid, both in terms of structure and function. This object is accomplished by dividing the liquid cooling system, which is embodied as a closed system, into at least two liquid loops (13, 17). The advantage that can be attained with the new liquid cooling system is that the liquid loops can be adapted to one another such that the temperature and output of the consumers match. The pipe cross-sections and pumps can therefore be kept small.

  • Patent number: 6427463
    Abstract: A method using controlled forced-convection to couple (or de-couple) a refrigerant-evaporator thermally to a refrigerated compartment, and a method to use heat from a fresh food compartment (or other compartment maintained above 0C) of a two or more temperature refrigeration appliance to defrost a freezer evaporator automatically without using a controller or heater. When thermally coupled to its compartment, an evaporator can provide efficient cooling to the compartment. The ability to de-couple the evaporator from its compartment enables refrigerant flow through the evaporator at significantly different temperatures than its compartment, but without significant heat transfer. This ability enables using a single refrigeration system (with one or no valves) to remove heat (sequentially) at two or more different temperatures from two or more refrigerated compartments.

  • Patent number: 6332335
    Abstract: By supplying a refrigerant utilized for cooling brine at a brine chiller unit (4) to a cooler (21) of a blast chiller (2), the internal space at the blast chiller (2) is cooled. In addition, the brine cooled at the brine chiller unit (4) is supplied to an ice heat storage tank (23) during the night and is supplied to a cold trap (7) during the daytime by switching a three way reversing valve (17). Thus, ice-making and chilled water storage are achieved at the ice heat storage tank (23) during the nighttime so that a tumble chiller (3) performs cooling during the daytime by using the chilled water that has been stored at the ice heat storage tank (23). Consequently, during the daytime, three coolers, i.e., the vacuum cooler (1), the blast chiller (2) and the tumble chiller (3), can be operated with a single brine chiller unit (4).

  • Patent number: 6327871
    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.

  • Patent number: 4862707
    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.

  • Patent number: 4748823
    Abstract: A freezer-refrigerator for automotive vehicles, which includes a freezing chamber and a refrigeration chamber. The freezing chamber includes a freezing evaporator and a first cold storage member. The refrigeration chamber includes a refrigeration evaporator and a second cold storage member. Both evaporators are connected in series so that refrigerant flows from a compressor through the freezing evaporator and then through the refrigeration evaporator under a control of a solenoid valve which is controlled by signal from a temperature sensor provided in at least one of the chambers, thus controlling the freezing and refrigeration. The freezing temperature of the second cold storage member is set higher than that of the first cold storage member thereby to maintain the interior of the chambers at a temperature near the freezing temperature of the cold storage members for long time even after the compressor stops.

  • Patent number: 4257169
    Abstract: A commodity dryer for removing or providing moisture and controlling atmosphere which surrounds stored commodities such as grain is provided which reduces the growth of bacteria, fungus and minimizes other deleterious conditions encountered such as in the storage of moist commodities which generally render them unfit for subsequent consumption. The commodity dryer maintains the integrity of stored commodities by creating a controlled atmosphere conducive to the removal or the addition of water by capillary action from the pores of the commodity and for controlling the moisture and temperature around the skin of the grain to achieve optimum storage conditions for the specific commodity stored.
