The air conditioner has a fan (11) and heat exchanger (12) mounted within an enclosure (20). There is a primary fan suction inlet (31) and a fan discharge outlet (32) in the bottom wall (21) of the enclosure, and an auxiliary fan suction inlet (33) in a side wall (22) of the enclosure, so that at least some of the air entering the enclosure and passing through the heat exchanger will be drawn from the space between the false ceiling and the true ceiling. Air reenters the interceiling space through holes and gaps in the false ceiling. The auxiliary fan suction inlet reduces radiated noise and improves air flow distribution in the room served by the air conditioner.

  • Patent number: 5507157
    Abstract: An indirectly cooled type cold storage unit adapted to effectively remove ethylene gas generated from storage products, and which can be easily handled during assembly, comprises a heat-insulating outer housing, an inner housing of high heat-conductive material located in the outer housing with a space therebetween and defining therein a storage chamber, and a cooling device for circulating cold air in the space between the outer and inner housings whereby the inner housing is cooled so as to indirectly cool the storage chamber and its contents. An adsorbing and decomposing sheet-like agent composed of ethylene decomposing catalyst and active carbon is provided in communication with the inside of the storage chamber in a manner such that the ethylene gas passes only through the box and not through the space between the two housings.

  • Patent number: 5442932
    Abstract: A cooler chest has an open top which may be covered or uncovered by removable doors. A plurality of downwardly directed jets around the upper periphery of the chest forces cold air into the bottom of the chest, thereby displacing warm air from the chest and into the ambient atmosphere. The cold air in the chest is drawn through an evaporator coil for further cooling and then returned to the jets at the upper periphery for a continued cooling of the chest.

  • Patent number: 5377502
    Abstract: Ripening retardation chamber apparatus includes a plenum chamber having a generally open side against which is disposed a pallet full of boxes containing produce. The boxes include openings to allow cooled and moistened air to flow therethrough. An evaporative cooling system is used to provide a flow of cool, moist air into the plenum chamber. The air flow is such as to cause the cooled, moistened air to flow from the plenum chamber through the cartons or boxes of produce. The flow of air causes the heat and ethylene gas produced by the ripening produce to be moved out of the boxes, thus retarding the ripening process. The presence of moisture in the air reduces weight loss of the produce and improves the outer appearance of the produce.

  • Patent number: 5315846
    Abstract: A refrigerator has freezing and refrigerating compartments arranged above and below one another. A hollow duct extends vertically through said freezing and refrigerating compartments and receives a flow of cool air at its upper end. The duct includes vertically spaced holes through which the cool air is discharged into the freezing and refrigerating compartments. The duct is freely rotatable about its longitudinal axis and carries fins arranged at the discharge holes such that the discharging cool air impinges against the fins to cause the duct to rotate.

  • Patent number: 5271233
    Abstract: A method and apparatus in which a container is provided with a refrigeration facility. A holder for holding carbon dioxide snow is placed within the interior of the container so that the carbon dioxide snow is in gaseous communication with the interior of the container. The holder or a continuous wall region of the holder, constituting about 15% of the total wall area of the holder, is fabricated of a flexible material that is at least substantially impermeable to the carbon dioxide snow and permeable to gaseous carbon dioxide. Additionally, a combination container and holder is disclosed along with a combination holder and support structure. The support structure is attachable to the container to support the holder so that the carbon dioxide snow is in gaseous communication with the interior of the container.

  • Patent number: 5181167
    Abstract: Heatpipe elements having a thin flat, rectangular geometry are contstructed according to known heatpipe techniques. An electronic circuit module incorporating multiple discrete and integrated circuit elements is integrally imbedded into a recessed top exterior surface of each heatpipe element. The heatpipe elements are longer in one dimension that the circuit modules imbedded therein, the excess length being partitioned equally on each side of a circuit module. The remaining opposing edges of each circuit module equally overhanging the lateral edges of the heatpipe are configured as area array connectors. The resultant heatpipe/circuit module forms bilateral thermal contact areas for thermally contacting complementary surfaces of immediately adjoining heatpipe/circuit modules. Circuit modules electrically contact preceding and succeeding circuit modules via stacking connectors interposed between the respective area array connectors.

  • Patent number: 4884411
    Abstract: A high humidity refrigeration apparatus and method are disclosed. The high humidity refrigeration apparatus has an air inlet at a top thereof and an air outlet in a front thereof. The arrangement is such that when the high humidity refrigeration apparatus is fitted at one end of a chamber, such as a shipping container, goods in stacks, such as on pallets, can be loaded into the chamber from the other end of the chamber. Because the air which exits the outlet is the coldest and of the highest humidity available from the apparatus it is then caused to contact those goods which have been first loaded into the chamber before it contacts any subsequently loaded goods. This ensures that the first loaded goods are always kept as cold and in as high a humidity environment as possible.
