Abstract: A refrigerator is improved in storage environment by suppressing drying and oxidation and enhanced in volume efficiency and cooling efficiency. The refrigerator includes a refrigerating chamber, a vegetable chamber, and a freezing chamber in order from its top to its bottom. Cool air is introduced into the freezing chamber by a first cooler and a first fan, and is introduced into the refrigerating chamber by a second cooler and a second fan. These chambers function as a direct cooling chamber. The vegetable chamber functions as an indirect cooling chamber cooled by a cooling plate which is disposed at the top of the chamber and has a large thermal conductivity, which is cooled by forced convection by the second cooler and the second fan, producing the effects of low temperature radiation and natural convection in the chamber.

Abstract: The invention allows cool rooms or sea containers designed for frozen goods to handle produce requiring more precisely controlled temperatures and conditions, e.g., vegetables and fruits requiring temperatures in the chilling range and often also needing control or modification of the atmosphere. Each load of produce (100) (e.g. of pallet size) is held in the sea container or cool room but is sealed from the air of the refrigerated environment by, for example, a plastics bag (56). The atmosphere within the bag is then circulated by a fan (12) (or by convection currents from a heating element) so as to pass through the load and around it via ducts (30) provided adjacent the bag (56). Heat exchange (50) between the circulating gas and the refrigerated environment, via the plastics film, serves to cool the load. However, if cooling is excessive a heating element can be used to raise the temperature of the circulating atmosphere. Gas composition of the atmosphere can be controlled by scrubbing, flushing, etc.

Abstract: A chilled beverage display container has an outer casing that includes a base, a top rim member, a cover hinged to the top rim member so that the cover can be pivoted between a closed position and an open position, and a circular cylindrical peripheral wall member of a transparent material, the peripheral wall member being sealed to the base and to the top rim member so as to prevent substantially any flow of a gas into or out of the outer casing. A tub of a transparent material having an upper rim portion, a peripheral wall, and a bottom wall, is supported within the outer casing solely by attachment of the upper rim portion of the tub to the top rim member of the casing. The peripheral wall of the tub is spaced apart from the peripheral wall of the outer casing and the bottom wall of the tub is spaced apart from the base of the outer casing so as to form a dead air space between the tub and the outer casing.

Abstract: A refrigerator includes a fresh food compartment, a freezer compartment defined by inner walls and an outer case respectively, an insulation barrier separating the compartments, and doors for providing access to the compartments. A passageway is formed in the barrier for providing refrigerated air to the fresh food compartment. A connecting duct diverges from the passageway and extends forwardly towards the front portion of the fresh food compartment. A door duct communicating with the connecting duct when the door is closed is coupled to the door. As a result, the fresh food compartment and door-adjacent portions of the fresh food compartment are promptly and uniformly cooled.

Abstract: Sample analysis in a portable analytical instrument, preferably in the form of a gas chromatograph, benefits from temperature control of one or more thermal zones in the instrument by way of a thermal isolation system that includes a novel pumping assembly to effect a selective amount of thermal isolation of the thermal zone.
