Abstract: If a motor breaks down, an appropriate measure is taken according to the type pf the breakdown. If the breakdown is judged to be due to abnormal energization of the motor by electrical abnormality judgment means, a drive source for a hybrid compressor is secured while preventing an engine for traveling from stopping by compressor operation continuation means. If it is judged that the driven state of the motor is abnormal, the hybrid compressor is disconnected from the engine to protect the engine from mechanical abnormality of the hybrid compressor.

Abstract: A camper cooling device is disclosed for a camper in the bed of a pickup truck comprising a holding tank, an intake grill, cooler pads, a plurality of adjustable vents, a maintenance door, and an overflow and drain tube. In accordance with a preferred embodiment, the camper owner first inserts ice into the rear of the holding tank located on the top of the camper. This insertion of ice can be accomplished by standing on the rear bumper, tailgate, or ladder. When the camper is mobile, air flows through the intake grill and over the cooler pads located at the front of the system. The ice cools the incoming air. Vents situated inside the camper compartment direct cold air circulation within the camper. An overflow and drain tube is positioned in the rear of the system to drain excess water.

Abstract: A cooler for use with gaseous process fluids such as air containing a vapor has a vapor adsorption unit for passing process air through an adsorption media to dry the air, a heat exchanger to control the temperature of the heat adsorption media and process air, a vapor removal system for removing the adsorbed vapor from the adsorption media, and a humidification unit to add a vaporizable liquid to the dried process air, so as to vaporize the liquid into the dried process air. Thus, heat in the process air is utilized for the latent heat of vaporization of the liquid to reduce the temperature in such process air, while maintaining a predetermined humidity level in said air. The vaporizable liquid may be sprayed into the process fluid as a mist. Excess cooled coalesced liquid may be used in a heat exchanger to precool the process fluid before it enters the humidifier.

Abstract: The components of a compact, dual stage air conditioning system are assembled within a common housing in which an evaporator airflow passage is separated from a condenser airflow passage by an interior panel. Dual stage operation is provided by a pair of evaporator coils which are interleaved about a common evaporator core, and by a pair of condenser coils which are interleaved about a common condenser core. A control circuit automatically enables single stage operation when on-board generator power is applied, and automatically enables dual stage operation for increased cooling capacity when commercial utility power is available.

Abstract: In a method for the thermal conditioning of electronic equipment mounted on aircraft, a flow of ram air is tapped and transferred to first means enabling said flow of air to be given a first negative gradient of temperature after which, if necessary, the flow air coming from said first cooling means is transferred to second means capable of giving a second negative gradient of temperature to said flow of air, after which the flow of air coming directly from the first cooling means, combined as the case may be with the flow of air coming from the second cooling means, is transferred to the immediate vicinity of the electronic equipment to be cooled, thus achieving an appropriate thermal conditioning of said electronic equipment. The disclosure also relates to the systems designed for the implementation of this method.

Abstract: A helmet cooling system has a receptacle containing a coolant through which air flows, impelled by the velocity of the vehicle on which the system is used. The air is ducted from the receptacle to the interior of the helmet. A flexible conduit transmits melted coolant to a mouthpiece within the helmet for refreshing the helmet wearer.

Abstract: An air/liquid heat exchanger having a tube that reinforces the heat exchanger's core and header plates and also sprays a liquid onto the core for evaporative cooling.

Abstract: An airflow control system (10) in accordance with the invention includes an air channel (14) having a single opening (16) for receiving ram air and for inducting air into the channel; a fan assembly (20) disposed within the air channel including a fan which is activated for inducting air through the air channel and through a fan channel (30) disposed within the air channel, the fan having an inlet (42) in the fan channel and an outlet (44); and a mechanism (50) responsive to ram air within the air channel for closing the outlet to at least lessen freewheeling of the fan which would occur if the fan channel was open for passage of ram air and responsive to induction of air by the fan into the channel to cause the inlet and the outlet to be open.

Abstract: A transport refrigeration unit of the mechanical refrigeration type and including a start-stop mode of operation is driven by an engine 20 which is coupled through belt 34 to a common shaft 32 for the condenser fan 26 and evaporator fan 30, through a clutch 38 which is selectively operable to drive the shaft 32 when the engine 20 is operating, and to decouple from the shaft 32 when the engine 20 is not operating so that ram air pressure to the condenser fan will in turn drive the evaporator fan to provide at least some air circulation in the interior space of the trailer.

Abstract: An air deflector unit for use on a vehicle to improve aerodynamic flow of air around the vehicle includes a forward facing shield having a forward facing air inlet therein and an inwardly facing air exhaust. An air flow passage is defined between the air inlet and the air exhaust. An air conditioning compressor is mounted in the air flow passage. Flow of air through the condenser is controlled by controlling louvers positioned in the inlet. Control is in response to the operation of the air conditioning system of which the compressor is a part.

Abstract: The device comprises an elongated container (2) which can be attached to the roof (1) or a wall of a vehicle in close engagement therewith and transversely of a direction of travel. The container carries a supply of evaporation liquid (9), and contains an absorbent mat (7a) which emerges from the container at the rear lower edge thereof. The container (2) and mat (7a) can be mounted detachably on the roof (1) or the wall. The container (2) may have a cover (3) and be profiled in the manner of a spoiler. The mat (7a) is adapted to be withdrawn from the container (2) and fixed in its withdrawn state. To produce an excess pressure in the interior of the container the container (2) may have one or more ventilation openings (3c).

Abstract: In a compressed air powered refrigeration system for aircraft containing a refrigeration turbine and associated heat exchangers for supplying cool air to the aircraft cabin, air is recirculated from the cabin by a recirculation means and combined with the turbine discharge air to simultaneously melt ice present in the turbine discharge and provide cooling to the recirculated air. The lack of ice in the turbine discharge allows the use of an ice-free regenerative heat exchanger, in heat exchange relation with the mixture of the turbine discharge air and recirculated cabin air, to condense moisture from the air entering the turbine. The use of heat from the cabin air to melt ice coupled with maximum utilization of the recirculation means supplying the recirculating cabin air enables the turbine to provide air at a temperature below freezing and results in improved cycle efficiency as well as maximum possible ventilation rate to the load.
