Abstract:
The present heating, ventilation and air conditioning (HVAC) air conveyance apparatus is plurality of panels adapted to be field-assembled to form the conveyance apparatus. These panels include a pair of first quadrilateral panels, each defining a right-angle flange extending from each of a pair of opposite edges and a pair of second quadrilateral panels, each defining a hemmed cleat along each of a pair of opposite edges. Each hemmed cleat is shaped and dimensioned to receive one of the first quadrilateral panel right-angle flanges to form the HVAC air conveyance apparatus. Also, HVAC unit mating flanges extending from each other edge of each of the first quadrilateral panels and/or from each other edge of each of the second quadrilateral panels, such that at least a pair of opposed peripheral HVAC unit mating flanges extend from each end of the HVAC air conveyance apparatus.
Abstract:
Aspects of the present disclosure include a primary air chamber configured to receive primary air, an induced air chamber configured to receive secondary air, a heating coil disposed in the induced air chamber, wherein the heating coil is removable from the induced air chamber without disassembling at least a portion of the induced air chamber, and the heating coil does not receive the primary air, a fan disposed in the induced air chamber, wherein the fan is configured to blow the secondary air received via the induced air chamber toward the heating coil and the heating coil heats the secondary air.
Abstract:
A personal cooling device utilizes a portable container for retaining a liquid that is wicked into a wicking, material and a fan to draw air into the container through a plurality of apertures to produce a flow of cool air. Air drawn into the container through the apertures flows through the wicking material and is cooled by evaporative cooling. The air then flows out of the top of the container and through the air moving device. A funnel is configured around the outer perimeter of the container to capture any liquid that spills out of the apertures and direct it back into the container. A battery pack may be coupled to the air moving device by an extension cable for storing the battery pack in a more convenient location, such as on a belt.
Abstract:
This invention relates to HVAC systems, zone control units, and control systems. More specifically, an HVAC system employs distributed zone control units that provides localized air recirculation. A zone control unit includes a return air section that receives return air from serviced building zones and mixes the return air with a supply of outside air. The mixed air is heated and/or cooled by the zone control unit and discharged to serviced building zones in a controlled manner. An exhaust air system is used to extract air from serviced building zones. The HVAC zone control unit also includes a local control unit with an Internet protocol address. The local control unit includes a memory and a processor for storing and executing a control program for the zone control unit. The control program controls of the zone control unit in response to commands received via the Internet.
Abstract:
An insulated HVAC duct component such as a transition box includes a first insulation layer and a second, different insulation layer. The transition box includes at least four sidewalls and one of a top and a back wall, the transition box further including a first access port and a second access port, the first access port having a different cross section than the second access port, one of the access ports being spaced from a nearest sidewall by less than 2 inches. The first insulation layer is located along an inside surface of the box. The second different insulation layer overlies the first insulation layer, the second different insulation layer having an air impervious surface, wherein the combined thickness of the first insulation layer and the second different insulation layer is less than 2 inches.
Abstract:
A steam dispersion system is disclosed. The steam dispersion system includes a header and a mounting plate spaced from the header. A steam dispersion tube including a first end and a second end and an interior cavity defined between the first end and the second end is mounted between the mounting plate and the header. The steam dispersion tube defines a longitudinal axis. A biasing structure is mounted between the mounting plate and the header, wherein the biasing structure applies a biasing force on the steam dispersion tube along a direction parallel to the longitudinal axis of the steam dispersion tube when mounted between the header and the mounting plate.
Abstract:
A collapsible air duct with inflatable insulative sleeve for supplying preconditioned air from a remote source to aircraft and similar vehicles. The system includes first annular interior chamber substantially surrounded by an a non-rigid inflatable sleeve which provides a thermal barrier from adverse environmental conditions. The non-rigid inflatable sleeve is filled by a portion of the air supply transiting the annular interior chamber through a series of perforations, thus providing an insulative air layer.
Abstract:
A duct element (1) for an air flow or for a gas flow and a method for manufacturing, handling and mounting the duct element (1). The novel duct will replace ducts of steel and thus have enough restraint towards flexure to be hung without any substantial flexure in connection to a mounting procedure. The advantages are a substantial reduction in price per meter of duct installed, and it makes manufacturing, handling and mounting easier as well as transportation and storing as the duct (1) can be folded or rolled in a flattened and space saving condition. The duct (1) can be bent in a mounted position, i.e. be allowed to be changed in direction having a minimum radius of about 1000 mm.
Abstract:
An expansible and collapsible tubular conduit, which is especially adapted for use in supplying pre-conditioned air to an aircraft while the aircraft is located upon the ground and is being serviced, comprises a plurality of annular fabric membranes which are connected to the opposite sides of a plurality of annular structural dividers or frame members in a continuously repetitive alternating manner. The structural combination or assembly comprising the fabric membranes and the structural dividers or frame members renders the tubular conduit readily expansible and contractible in the form of a spring or accordion so as to be capable of being easily and rapidly deployed and stowed, as well as to be capable of being stored in a relatively compact state or mode.
Abstract:
The present invention relates to a method for producing ductwork connecting components (1) preferably for air-handling systems. The essence of the invention lies in that providing a foam-related material made of chemically cross-linked polyolefine with closed cell-structure, preparing the pattern (4) of a connecting component from a foam-sheet of polyolefine, cutting out the pattern and forming the final shape of the connecting component by welding the corresponding edges. The present invention relates further on to connecting components prepared according to the method of the invention. The invention also relates to an air-handling system using the connecting components of the invention.
