Abstract: The invention relates generally to a novel cooling system and fuel preheating system for use in an advanced, high speed aerospace vehicle. A hydrocarbon fluid, such as fuel is accelerated to supersonic conditions within a cooling channel located proximate a high-temperature flight surface. The hydrocarbon fuel absorbs a heat load as it passes through the cooling channel in the flight control surface prior to the fuel being directed into the aircraft engine.

Abstract: A fluid flow system comprises a first pump and an ejector downstream of the pump. The first pump facilitates the flow of a driver fluid through the ejector. In the ejector, the driver fluid mixes with a suction fluid. The ejector is operatively coupled to a fluid reservoir, which in some cases is associated with a cycle having a second pump and an evaporator. The fluid reservoir includes the suction fluid. A heat exchanger downstream of the ejector removes heat from the driver fluid, and from the heat exchanger the driver fluid is directed to the first pump. The fluid flow system can include a fluid separator downstream of the ejector for separating the driver fluid from the suction fluid.

Abstract: Provided herein is a vapor absorption system, adapted to receive a vapor comprising a vacuum pump having an operating liquid, where the vapor is received by an operating liquid and condensed therein to provide condensed liquid mixed with the operating liquid.

Abstract: An apparatus and method for detecting a fire in a household dryer and responding thereto.

Abstract: A vehicle heating and cooling system having a first coolant loop selectively connecting an engine cooling system with a heater core or a first coolant/refrigerant heat exchanger, a second coolant loop connecting a second coolant/refrigerant heat exchanger and the heater core to warm a passenger compartment of the vehicle. The system also includes a refrigerant loop that provides for conventional cooling of the passenger compartment of the vehicle, as well as operating as a heat pump, together with the coolant loops, to provide heat to the vehicle passenger compartment.

Abstract: An air cycle system for use in a vehicle having an internal combustion engine is provided. A compressor has an outflow to an intercooler with an outflow to a first bypass valve. The first bypass valve has an open and a closed orientation, directing air to the engine of the vehicle in the open orientation and directing air to an expander in the closed orientation. The expander has an outflow to a second bypass valve that is adjustable so it can direct a variable fraction of air to the engine and the remainder of the air to an air handling unit. The air handling unit has at least a fan, a scroll center, and first and second air flow paths. The first air flow path has an input at the scroll center from the second bypass valve and the second air flow path has an input at the fan from the interior of the vehicle. The air handling unit mixes air from the first and second flow paths and directs the mixed air to the interior of the vehicle.

Abstract: A vehicle heating and cooling system having both a coolant loop with a heater core employing a coolant to warm a passenger compartment of the vehicle, and a refrigerant loop with an air conditioning system for cooling the passenger compartment of the vehicle. The refrigerant loop and coolant loop can also operate together where the air conditioning system is operating as a heat pump and drawing heat from the coolant loop.

Abstract: A method and system for climate control uses a desiccant in an automobile. The desiccant removes humidity or moisture from air passing through the ventilation system. The desiccant is recharged or dried by application of a vacuum. The lower pressure generated by the vacuum reduces the temperature at which water evaporates or boils off of the desiccant material.

Abstract: A cooling system for an automotive vehicle is disclosed including a heat exchanger assembly, a rotatable axial flow fan and a shroud member at least partially surrounding the fan and the heat exchanger assembly. The cooling system further includes a first ejector disposed between the heat exchanger and the engine and a pair of second ejectors disposed on the inner fender members of the vehicle for drawing ambient air from under the heat exchanger and pumping the air toward the engine and for preventing recirculation of the air exiting the shroud member back to the fan while the vehicle is at idle.
