A portable environment control system is configured to condition the air within an enclosure, such as by heating, cooling, humidifying or dehumidifying. The portable environmental control system has a conduit that is attached at one end to an environment control device and attached at the opposing outlet end to a partition coupling. The partition coupling is configured over an opening in a partition, such as an exterior wall of a recreation vehicle. Airflow from the environment control device is configured to flow through the conduit and through the partition coupling to an enclosure. The portable environment control system is quick and easy to install and allows for closure of an opening in a partition with a flange cover. The portable environment control system may have an inlet and outlet conduit to provide air flow to and draw air flow from an enclosure, respectively.

A robotic system is provided for repeatedly and reproducibly applying a sealant to a seam in an assembled HVAC duct component. The applied sealant has a predetermined location on the assembled HVAC duct component to seal the seam. An assembled HVAC duct component is thus provided having a robot applied sealant on at least one seam in the assembled HVAC duct component, wherein the applied sealant has at least one of a predetermined location, thickness or coverage. The robotically applied sealant can be applied to a blank for forming the assembled HVAC duct component, wherein the sealant is located at locations forming a seam in the assembled HVAC duct component.

The present double walled grease duct includes a tubular outer shell surrounding a tubular inner liner, wherein a spacer is positioned perpendicular to the walls of the outer shell and the inner liner. The spacer can include a plurality of vertical metal strips extend from a top edge of the spacer to the bottom edge of the spacer, wherein the top edge of the spacer contacts the walls of the outer shell and wherein the bottom edge of the spacer contacts the walls of the inner liner. The metal strips resist the different rates of thermal expansion between the outer shell and inner liner ultimately preventing the collapse of the inner liner under pressure from thermal expansion.

An air conditioning unit and method of mounting the same in an opening in a wall, particularly an opening housing a window. The unit includes a front section disposed inside the building on a first side of the opening; and a rear section disposed outside the building on a second side of the opening. A duct extends between the front and rear sections and is clampingly engaged between the sill and a bottom end of the window. The duct includes a first duct member that moves cooled air in a first direction towards the inside of the building; and a second duct member that moves return air in a second direction away from the inside of the building. The duct is changeable in length to alter the distance between the front and rear sections so as to accommodate the air conditioning unit's installation in windows in different thickness walls.

A duct in which the welding strength of the parting lines is enhanced and which facilitates the attaching job is provided. The duct of the present embodying mode has a mean thickness of the entire duct of 1 mm or less, and includes projections on inner surface sides of the duct on the parting lines.

A ventilation unit includes a housing including a plurality of walls defining an interior space. The housing may be mounted to a structure, such as a cabinet, using a plurality of primary mounts. A mount is coupled to the housing to mount the housing to the structure. The mount may be used prior to installation of the primary mounts.

This invention provides a under cabinet ducting kit comprising an under cabinet supply cover; at least two oval collars, wherein a first oval collar is connected to the under cabinet supply cover at a first end; a flexible duct hose, wherein a first end of the flexible duct hose is connected to the first oval collar at a second end, and wherein a second end of the flexible duct hose is connected to a first end of a second oval collar; a toe kick backer plate, wherein a second end of the second oval collar is connected the toe kick backer plate; and at least two metal band straps, wherein the metal band straps attach the flexible duct hose to each of the first and the second oval collars.

An air duct having first to third air ducts, each of the first to third air ducts has a duct structure having a first end and a second end, the duct structure of the each of the first to third air ducts are separable from each other, a cross sectional area of the first end is greater than a cross sectional area of the second end, a plurality of cross sectional areas between the first end and the second end decrease progressively from the first end to the second end, and the first to third air ducts are communicated successively in a direction such that the second end of the duct structure of the third air duct is arranged closer to the second end of the duct structure of the first air duct and further from the first end of the duct structure of the first air duct.

A fire-rated ventilation duct system and improvements therein. According to an embodiment, the fire-rated ventilation duct section comprises, an inner liner configured as conduit for air movement, the inner liner comprising a metallic material and having a first end and a second end, and the first end including a first connection section, and the second end including a second connection section; an outer casing configured for encasing the inner liner, the outer casing comprising a metallic material having a fire-rating, the outer casing having a first end and a second end, and the first end including a first duct connection section configured for joining one end of a second fire-rated ventilation duct, and the second end including a second duct connection section configured for joining one end of a third fire-rated ventilation duct; an insulation layer configured to provide a thermal insulation layer between the inner liner and the outer casing, and the first connection section of the inner liner further comprising a first liner spacer and the second connection section of the inner liner further comprising a second liner spacer, the first and the second liner spacers being configured to define a cavity for receiving and positioning said insulation layer between an outer surface of the inner liner and an inner surface of the outer casing; the first duct connection section of the outer casing being configured to attach to at least a portion of the first connection section of the inner liner, and the second duct connection section of the outer casing being configured to attach to at least a portion of the second connection section of the inner liner to form a sealed duct section.
