Abstract: An illustrative example embodiment of a structure for supporting a heating, ventilation and air conditioning (HVAC) unit includes a frame having support members configured to be situated beneath the HVAC unit to support a weight of the HVAC unit, which is directed in a vertical direction. The frame is at least partially situated in a plane that is perpendicular to the vertical direction. A supply air passage and a return air passage are supported by the frame. The return air passage has a first side and a second side opposite the first side. The first side is oriented at a first oblique angle relative to the plane. The second side is oriented at a second oblique angle relative to the plane. The first oblique angle is different than the second oblique angle.

Abstract: An HVAC system includes an indoor heat-exchange coil disposed between a supply air duct and a return air duct. A damper is disposed in a re-circulation duct and is moveable between an open position and a closed position. A controller is configured to determine if the HVAC system is operating in a heating mode or an air-conditioning mode. Responsive to a determination that the HVAC system is operating in the air-conditioning mode, the controller is configured to determine if the variable-speed indoor circulation fan is operating at a minimum speed and if the relative humidity measured by the humidity sensor is above a pre-determined threshold. Responsive to a determination that the variable-speed indoor circulation fan is operating at the minimum speed and the relative humidity of the enclosed space is above the pre-determined threshold, the controller signals the damper to move to the open position.

Abstract: A fan duct includes a branch wall and ribs. The branch wall includes two plate-shaped portions that are continuous with each other at sides thereof on the upstream side in the air blowing direction of the fan and are inclined relative to the air blowing direction such that the two plate-shaped portions are separated from each other toward downstream in the air blowing direction of the fan, and the branch wall is disposed on an inner side of edges of the air outlet. The ribs protrude from a surface of the branch wall facing the heat sink, each of the ribs has a mountain-shaped plate shape with a most protruding top portion having an acute angle, and a plurality of the ribs are provided side by side in a thickness direction of the ribs.

Abstract: An air treatment device includes a case having fresh and supply air ports, and return and exhaust air ports. In the case, a supply air route is formed from the fresh to the supply air ports and an exhaust air route is formed from the return to the exhaust air port. The supply and exhaust air routes are provided with fans. A heat exchanger cause heat exchange between air flowing in the supply and exhaust air routes. The heat exchanger includes multiple layers of heat exchange core fins, and multiple layers of films stacked alternately. A section perpendicular to an air flow direction and upstream of the heat exchanger includes first and second regions. In the heat exchanger, the films adjacent to each other have a gap H1 in the first region, and a distance H2 in the second region, with H1

Abstract: A single-package air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, and a plenum. The housing may define an outdoor portion and an indoor portion. The plenum may be attached to the housing and receivable within a wall channel defined by a structure wall. The plenum may define a primary air channel and a make-up air (MUA) inlet in fluid parallel with the primary air channel. The primary air channel may be disposed in fluid communication with the outdoor portion to permit air therebetween. The MUA inlet may be in fluid communication with the indoor portion to permit air thereto.

Abstract: An air conditioner includes a heat exchanger, a fan and a fan case in which the fan is accommodated. The fan case includes an inlet opening through which air sucked by the fan enters the fan and an outlet opening through which the air that entered the fan is blown by the fan to be discharged from the fan case. An air guide is spaced from a lower end portion of the outlet opening to form a gap through which the air flows to guide the air to a down direction. The air guide includes an inclined portion inclined downward toward an outer side in a lateral direction to guide air to the lateral direction.

Abstract: Provided is a duct damper comprising: a hollow housing provided inside the duct so as to enable ventilation; a blocking plate provided in the housing and opening and closing the hollow; a fastener detachably fixing the blocking plate to the housing; and shape maintaining members respectively provided on the sides of the blocking plate so as to respectively maintain half of the shape formed by the blocking plate. According to the present invention, even if both sides of the blocking plate are bent with a center bar as an axis, since the shape maintaining members half and half support the both sides of the blocking plate, respectively, so as to maintain the shape, vibrations are not generated at either side of the blocking plate, thereby preventing noise.

Abstract: Methods and systems to measure a volumetric fluid flow rate through a fluid flow passage, such as an air handler of a HVAC system, are described. The method may include obtaining a flow rate measurement in a measuring section, and calculating a total flow rate based on a correlation between the obtained flow rate measurement and the total flow rate. The method may also include blocking a portion of the fluid flow passage so that when a minimal volumetric fluid flow rate is provided, the flow rate measurement obtained in the measuring section is at about a minimal sensitivity flow rate requirement.
