An internal heat exchanger assembly for an air conditioning system, having a substantial cylindrical cavity in which a helical coil tube is coaxially disposed within the cylindrical cavity. A bleed valve assembly is incorporated into the helical coiled tube, in which the bleed valve assembly is adapted to open at a predetermined differential pressure between the high pressure side and low pressure side of the internal heat exchanger. The bleed valve selectively bleeds refrigerant from the high pressure side to the low pressure side, thereby increasing the pressure and mass flow rate of the refrigerant to the suction side of a compressor.

Internal heat exchanger assembly having an internal bleed valve assembly

An integrated structural system for a vehicle, the system having: a structural member; a means for securing a first beam component to the structural member, the first beam component being molded from a first amount of thermoplastic material; and a means for securing a second beam component to the first beam component, the second beam component being separately molded from a second amount of thermoplastic material, the second beam component having a configuration different from the first beam component.

Integrated structural member for a vehicle and method of making

An integrated structural system for a vehicle is provided, the integrated structural system having: a structural member; a first beam component secured to the structural member by a molding process, the first beam component being molded from a first amount of thermoplastic material, wherein the configuration of the first beam component is defined by the molding process; and a second beam component secured directly and only to the first beam component by a vibration weld, the second beam component being separately molded from a second amount of thermoplastic material, the second beam component having a configuration different from the first beam component.

The assembly includes a pair of heat exchangers, each including an upper and lower manifold, parallel and spaced relative to one another. Tubes extend between each set of upper and lower manifolds with fins disposed between each of the tubes. A valve system controls fluid flow between the upper manifolds and the lower manifolds. The valve system is movable between a maximum cooling mode with fluid flow form the first upper manifold through both of the tubes and to said first lower manifold. A temperate mode allows fluid to flow from the first upper manifold to the first lower manifold and from the second upper manifold to the second lower manifold to prevent flash fogging. A maximum cooling mode allows fluid to flow from the second upper manifold through both of the first and second tubes to the lower manifolds.

Secondary loop-integral heater core and cooler

A method for forming an integrated structural system for a vehicle is provided. The method including the steps of: securing a first beam component to a structural member by a molding process, the first beam component being molded from a first amount of thermoplastic material, the structural member being formed from a material different than the first amount of thermoplastic material; and securing a second beam component to the first beam component, the second beam component being separately molded from a second amount of thermoplastic material, the second beam component having a configuration different from the first beam component.

An air inlet assembly for an automotive heating and ventilating air conditioning (HVAC) system includes a casing extending along an axis (A). The casing defines a plurality of inlets for receiving air and an outlet for delivering air from the inlets. A filter filters air between the inlets and the outlet. An air moving device disposed about the outlet for expelling air from the casing. A valve mechanism supports the filter. Furthermore, the valve mechanism moves along the axis (A) between an outside-air position and a cabin-air position for controlling air from the inlets to the outlet.

Air inlet assembly

An endless filtering sheet, having an interior entrained about rollers, extends in a path of movement over an air inlet in a housing for receiving air flow and presents an exterior from which dirt and debris collected from the incoming air flow and which dirt and debris is removed in a horizontal reach by gravity and/or an air flow. A drive mechanism continuously moves the sheet in the endless path to provide a continuously operating air filtration system for a heat exchanger in a HVAC system that is self-cleaning.

HVAC system with moving filter

A valve includes a film having side edges and an opening to extend across a passage in a housing of a HVAC system. The film has a circular aperture in the film adjacent each rounded corner of each opening for relieving stress. Either or both of the leading edge and the trailing edge of the film are undulated to prevent deformation of the edges. A pair of racks is disposed on the film and sprockets engage the teeth of the racks for moving the racks and the film linearly. Each rack includes a strap and bearing member for retaining the associated sprocket in engagement with the teeth. The bearing member is in rolling engagement with a bearing surface of the associated strap as it rotates with the sprockets.

Sliding valve, especially for heating, ventilation and air conditioning system

A novel air flow control valve for an air outlet in an HVAC housing provides for strong, even seal pressure all the way around the edge of the opening. In stead of a swinging door hinged at one edge of the opening, in which seal pressure is strong on the hinge edge but weaker on the opposite edge, a flat panel is moved straight toward and away from the opening. In the closed position, the sealing pressure is even all the way around. The sealing panel is moved back and forth by a rotary cam mechanism.
