Abstract: A portable cooling or heating system suitable for use on vehicle such as a car, plane or boat, that does not have its own air conditioning system. The system is intended to be combined with a portable cooler chest and includes an electric fan unit that can be powered from the power supply on a vehicle. The cooling is provided by ice and the like. The system can also be used to heat a confined space by placing a hot material in the chest.

Abstract: A portable cooling device includes an elongated chamber supported on a surface at an angle. The preferably cylindrical chamber holds a cylindrical bottle where an annular air space surrounds the bottle. The high efficiency design provides for adjusting the air direction with a one-piece pivotable outlet vent. A clamshell chamber made from two half-tubes allows easy plastic molding and access to the chamber interior for cleaning and for removal of the condensate tray. The integrated monolithic shape of the device fully encloses the working parts for a clean sanitary look.

Abstract: A cooling system for use with a typical ice container uses a pump that is disposed within a fluid held within the ice container. The pump pumps the fluid through a radiator located on a top cover of the ice container while a fan blows across the radiator. A plenum directs the cool air produced by the device. The fan can draw at least some of its air from within the ice container and can be thermostatically controlled.

Abstract: A water container and cooling fan assembly including a fan motor base, a cylindrical housing mounted on the fan motor face and covered with a top cover, and a water container put inside the housing, the water container having a plurality of longitudinal turning angles defining with the housing a plurality of longitudinal wind passages through which induced currents of air from a fan in the fan motor base pass, top cover having a smoothly curved wind guide face on the inside adapted for guiding induced currents of air from the longitudinal wind passages to an exhaust port.

Abstract: A cooling pack includes a plurality of thermally conductive shells made of a rigid plastic. Each shell contains a coolant and is securable directly to the protective housing of an electric fan. The shells are sized and shaped to allow the passage of fan air while the fan is operating. Heat is removed from the fan air flowing past the shells, thereby improving the cooling capability of the fan.

Abstract: An air-conditioning system comprising a portable air-conditioning unit (100, FIG. 1) for cooling and dehumidifying a zone and a refrigerating unit (10, FIG. 1) which is separated from the portable air-conditioning unit (100, FIG. 1). The portable air-conditioning unit (100, FIG. 1) comprises a housing (20, FIG. 1), an air-moving device (12, FIG. 1) and one or a plurality of coolant carriers (16, FIG. 1) which can be manually transported between the portable air-conditioning unit (100, FIG. 1) and the refrigerating unit (10, FIG. 1). The coolant carriers (16, FIG. 1) also function as cooling coils of a surface type heat-exchanger for the portable air-conditioning unit (100, FIG. 1). The coolant carriers (16, FIG. 1) are closed and sealed so that the contained coolant can be reused among cooling and refrigerating cycles. The coolant can be water or a solution of water and inorganic salt to make use of the combination of sensible heat, heat of fusion and heat of solution for cooling.

Abstract: A portable cooling apparatus. The apparatus includes a thermally insulated housing, such as a conventional hand-carried ice chest with a lid for removably covering the main opening. A thermally insulated dry ice chamber is disposed inside the chest. The dry ice chamber is vented and a fan is contained within the chamber. Dry ice is placed in the chamber and sublimates into cold gas which expands and passes from the vented chamber into the chest to cool the chest. Cooling action is increased by selectively actuating the fan to drive the sublimated gas rapidly into the chest, thereby causing air movement within the chest in a circulating flow pattern passing through the ice chamber.

Abstract: The low temperature food storage equipment of the present invention is provided with an icehouse and a food storeroom each surrounded by a heat insulator. The icehouse and the storeroom are connected by a detachable heat exchanger disposed therebetween. In the icehouse there is stored water which is frozen into ice when the outside air grows cold. In the storeroom there are kept in cold storage a large amount of shippable food, for example, potatoes. In the case of shipping the food, the heat exchanger is removed and the food is transported on a truck or the like while being kept in cold storage in the storeroom.

Abstract: The present invention relates to a palm-sized air conditioner. The palm-sized air conditioner includes a housing having a top with a vent; batteries are disposed within the housing; an ice chamber is disposed within the housing; a box fan moves air at room temperature through the ice chamber to produce cool air; and vertically adjustable horizontal vanes for receiving the cool air while the box fan passes the cool air up and out of the vent.

Abstract: A air conditioning device adapted to be used with a cup comprising a lid with a blower assembly means connected to the lid. The lid is removably connectable to an upper end of the cup and the lid has an air entry opening and an air exit opening. The blower means blows air into the air entry opening and the air passes into the cup space and over a substance in the cup space to provide an air exit stream. The air exit stream passes from the cup space through the air exit opening for passing a cool air exit stream from the lid. When the substance is a cool substance, the air exit stream is cool and, when the substance is a hot substance, the air exit stream is hot.

Abstract: An air conditioner system for bicycles and other vehicles, the system using a wheel of the vehicle as a source of power, air flow through an ice chamber being useable in the system as an optional further coolant.

Abstract: This invention is a portable ice chest, containing removable racks and trays for foods and beverages, replacable ice cubes and a fan driven by a battery powered motor.

Abstract: A refrigeration system for a catering truck includes a reservoir of ice cubes. A food compartment is provided for storing food under refrigeration and includes a cooling section adjacent thereto. Ice cubes are fed from the reservoir to the cooling section. A blower circulates cool air from the cooling section through the food compartment.
