  • Patent number: 6564575
    Abstract: An accumulator with an inlet port comprising a deflector for use in an air conditioning or refrigeration system, and a method for use thereof are disclosed. In operation, the accumulator is provided between the evaporator and compressor of an air conditioning or refrigeration system. Vaporized refrigerant is conveyed from the evaporator into the accumulator through an inlet port having a deflector. The deflector deflects the refrigerant from the inlet port in a spray pattern to reduce the velocity of the refrigerant thereby avoiding turbulence in the accumulator. In another embodiment, a vapor conduit inside the accumulator for conveying refrigerant to an outlet port has an open vapor inlet end with chamfered cut edges pointing away from the inlet port to avoid liquid from splashing into the vapor conduit.

  • Patent number: 6560979
    Abstract: Prevention of the incapability of operation due to crystallization in the absorption solution. When the temperature difference (&Dgr;T) between the temperature of the concentrated absorption solution Tr detected by the temperature sensor (22) and the temperature of crystallization Tc for the concentrated absorption solution at a specified concentration detected by the concentration sensor (21) comes within a prescribed figure, the opening of the heat control valve (20) is decreased by a specified figure, 20% for example. When the concentration of the concentrated absorption solution, which is measured by the concentration sensor (21), exceeds a prescribed figure, 65% for example, the heat supplied to the high temperature regenerator (1) is reduced by decreasing the opening of the heat control valve (20) regardless of the above temperature difference (&Dgr;T).

  • Patent number: 6557366
    Abstract: An apparatus for cold-holding food product. The apparatus comprises a cabinet carrying a refrigeration unit including a plurality of refrigerated shelves. The plurality of refrigerated shelves are adapted to frost on both sides under the control of the refrigeration unit to thereby maintain the quality of food product held on the shelves. To allow for the drainage of any melting frost, the plurality of shelves may be angled and a drain pan system included to direct the water away from the shelves to a drain or condensate evaporator during defrost periods. To prevent the removal of frost with the unloading of food products from the shelves, wire racks or trivets may be used to elevate the food product on baking pans above the frosted shelve surfaces.

  • Patent number: RE38181
    Abstract: An improved dehumidification system for automotive use includes a rotating, wheel like heat exchanger with axially open cells that carry a water adsorbing material. Opposed ambient air and heated air flows, covering opposite halves of the wheel, continually adsorb water on one side and are recharged on the other side. Alternating radially closed cells between the axially open cells carry no desiccant material, but receive a cross cooling flow, on the water adsorbing side of the wheel only, to remove the heat released during the water adsorption process. The desiccant recharging process on the other side of the wheel is not disturbed by the cross cooling flow.
