An integrated heat pump energy recovery ventilator system is provided for installing in a chase of a wall, the integrated heat pump energy recovery ventilator system comprising an air intake duct; an air outlet duct; a pump in fluid communication with the air intake duct; and in order: a heat pump compressor plate; an outer insulation panel; an outer energy recovery ventilator core; a heat pump evaporator plate and an inner energy recovery ventilator core, wherein the heat pump condenser plate, the outer heat pump energy recovery ventilator core, the evaporator plate and the inner heat pump energy recovery ventilator core all include at least a first series of channels and a second series of channels, the second series of channels disposed normal to the first series of channels, each series of channels.

A ventilation unit is for ventilating an indoor space, and incorporates an air cleaning device and mechanical restrictor for controlling a restriction to a flow resulting from a pressure differential across the unit. There is determination of the inside and outside air pressures in the vicinity of the unit and of air quality parameters inside and outside. The air cleaning device and the mechanical restrictor are controlled in dependence on the determined air pressures and air quality parameters. This provides a fan-less, and hence low-power ventilation unit, which relies on throttling the natural air flow across the unit to provide flow control, and hence enable control of air quality. The air cleaning device may be operated only when the flow is into the inside space, saving power.

The present disclosure relates to an air-diffusion system, a computer-implemented method of designing an air-diffusion system, an apparatus for additive manufacturing an air-diffusion system, and a method of additive manufacturing an air-diffusion system.

A connector configured to couple plural wall elements defining rooms or to couple insulating panels that are formed by filling a cavity with a fluid foam material wherein the connector is encased by the foam material, the connector including a housing that forms a base wall arranged in a base plane and a front wall arranged opposite to the base wall in a front wall plane; a pass-through opening formed in the front wall and configured to receive a locking hook; a receiving cavity configured in the housing for at least one locking element, wherein the housing forms an air duct, wherein the air duct extends from the front plane towards the base plane, and wherein the air duct includes an air inlet opening in the base plane and an air outlet opening in the front plane.

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.

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.

The present application provides a sealing plate assembly and an air conditioner having thereof. The sealing plate assembly includes a first sealing plate and a second sealing plate mounted on one side of the first sealing plate. The two sealing plates can slide relative to each other. There is a sealing plate joint provided with a vent hole mounted on the first sealing plate and located at the end opposite to the end where the second sealing plate slides out of the first sealing plate. A connector is used for connecting the first sealing plate to the sealing plate joint, such that the first sealing plate and the sealing plate joint can rotate relatively by using the connector as the axis. A telescopic sealing plate assembly is formed through a relative sliding of the two sealing plates to adapt to the sizes of different windows.

A ventilation system for ventilating a room, comprising: a lowered ceiling, defining a ceiling space between the lowered ceiling and a ceiling of the room and having an air permeable ceiling surface area; a raised flooring, supported by a support frame and defining a floor space between the raised flooring and a floor of the room, the raised flooring being air permeable over a floor surface area opposite to the air permeable ceiling surface area; an air supply inlet connected to the floor space; and an air outlet, connected to the ceiling space, wherein the air permeability of the raised flooring varies in dependence on distance from the air supply inlet for forming a substantial vertical air flow in which air entering the room through the floor surface area displaces air in the room in the vertical direction and forces air out through the ceiling surface area.

An exhaust fan includes a generally square housing, adjustable-height supports, and attachments for a variety of air ducts. The air ducts are each designed to provide a sufficient air seal to effectively enable the exhaust fan to evacuate dust and debris from a wide variety of standard doors or windows, either on the ground floor or an elevated floor.

To provide a structure that can improve air permeability from a first space to a second space and can prevent a building structure from increasing in size. A wall 11 has: a body section 35 separating an outside A1 from a living space B1 of a building; a ventilation device 30 provided in the body section 35; and a first ventilation channel 24 and a second ventilation channel 25 provided in the ventilation device 30, the first ventilation channel 24 and the second ventilation channel 25 sending air in the outside A1 to the living space B1, wherein arrangement ranges L1 and L2 of the ventilation device 30 in a thickness direction of the body section 35 are within an arrangement range L3 of the body section 35, and a cross-sectional area of the first ventilation channel 24 in a plane perpendicular to a virtual line E1 indicating a center of the second ventilation channel 24 narrows as it approaches the living space B1 along the virtual line E1.
