Disclosed herein are embodiments of a duct support assembly. The duct support assembly can include a frame structure and a duct support. The duct support can be configured to be installed in a floor assembly between a first beam portion of a first wall frame and a second beam portion of a second wall frame and to provide a duct exit from the frame structure. The duct support can be configured to transfer a tension and/or compression load. Also disclosed herein are embodiments of a method of using a duct support to provide a duct exit from a frame structure. The method can include positioning the duct support in a floor assembly between a first beam portion of a first wall frame and a second beam portion of a second wall frame.

Adjustable multi-tier floor vent system is provided. The adjustable multi-tier floor vent system includes grilles, guards, and components, which may be integrated or modular with the device, and which are configured to be modified to improve operation of the device. The adjustable multi-tier floor vent system device is configured for improved performance by allowing the height of the grille of the floor vent system to be adjusted by adding spacers and shims to a bracket. Adding spacers and shims to the bracket of the adjustable multi-tier floor vent system allows the grill to be raised to accommodate different thicknesses in flooring.

A device comprising a fin structure, a vent disposed in the fin structure, a cooling coil disposed in the vent, a light disposed in the fin structure and wherein the fin structure is configured to create a Coanda effect for air exiting the vent.

An under-floor HVAC system for a building includes a pliable air duct lying upon a subfloor. A matrix of pedestals resting upon and extending upward from the subfloor supports a set of floor panels, which thus creates a plenum between the subfloor and the set of floor panels. The air duct extends through the plenum to convey conditioned air from a supply air duct to a series of registers in the floor panels. The registers disperse the conditioned air to a room or area just above the panels. To help keep the air duct from repeatedly extending, retracting, and otherwise sliding freely along the subfloor in response to changes in air duct pressure, the air duct is held taut by anchoring a distal downstream end of the duct to one or more of the floor-supporting pedestals. Various air duct configurations can be assembled from a predefined assortment of duct components.

An air conditioning module including a thermo electric cell having a first side and a second side; an conditioning duct attached to the first side of the thermo electric cell; and an exhaust duct attached to the second side of the thermoelectric cell; wherein the conditioning duct receives and conditions air from a room, and the exhaust duct vents unwanted thermal energy.

A building system includes a building space defined by a structural ceiling and a flooring of a building, and a ceiling system. The ceiling system includes an air permeable suspended ceiling arranged below the structural ceiling, and a plenum space is formed between the suspended ceiling and the structural ceiling and a flooring space is formed between the flooring and the suspended ceiling. A plurality of partition wall sections is arranged in the plenum space extending between the structural ceiling and the suspended ceiling and forms a plurality of plenum modules distributed across the plenum space. Each plenum module includes equipment. The equipment of each plenum module includes a supply air device for delivery of supply air to the associated plenum module for pressurization thereof such that the supply air delivered to the plenum module is supplied to the flooring space through the air permeable suspended ceiling.

The invention non-direct vent (one pipe) or direct vent (two pipe) fuel fired appliance vent terminations spaced apart to accommodate the inward flow of combustion air and/or the outwardly flow of exhaust flue gas of a fuel fired appliance. The vent termination ends are capable of engaging the terminal ends of a variety of different size exhaust conduits including fitting sockets of a conduit fitting. The vent pipe termination can include in some aspects a vent pipe termination kit which may include, but not limited to; a vent termination main embodiment, mounting plate, screws, connector elements, threaded nuts, connector element cover, protection shield, intake screen, 90 degree elbows, sloped vent fitting, T fittings, wall anchors, decals or labels, escutcheon covers, insulating materials, caulking or other similar components.

An air inlet for an air handling unit includes a duct defining a passageway leading to the air handling unit. The fresh air inlet further includes an intake screen that is formed to include a plurality of openings sized to allow airflow to pass through the openings to the air handling unit. Particles are blocked from adhering and accumulating to surfaces of the intake screen.

The invention relates to a modular building structure (10) comprising: a framework (12) including a plurality of rods (14) and connectors (16) to interconnect the plurality of rods (14) together, the framework (12) comprising empty spaces bordered by corresponding rods (14) of said plurality of rods; a plurality of panels (20), wherein one panel (20) is mounted inside each empty space and connected to the framework (12) in order to create an interior (40), an air chamber layer (44) inside which air may circulate, said air chamber layer (44) forming at least a portion of an outer surface of said interior (40), at least one upper valve system (46a) mounted in the upper portion of the structure (10), and at least one lower valve system (46b) mounted in the lower portion of the structure (10). The at least one upper and lower valve systems (46a, 46b) are selectively operable to regulate the thermal conditions inside the interior (40) as a function of the meteorological conditions outside the modular building structure (10) and a desired temperature inside the interior (40). The invention also relates to a method for operating the at least one upper and lower valve systems (46a, 46b) of the modular building structure (10).

Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.
