摘要： Provided is an air passage type silencer that can reduce pressure loss even in a case where the flow rate of a gas flowing in the air passage type silencer is high. An air passage type silencer includes an inlet-side ventilation pipe, an expansion portion that communicates with the inlet-side ventilation pipe and of which a cross-sectional area is larger than a cross-sectional area of the inlet-side ventilation pipe, and an outlet-side ventilation pipe that communicates with the expansion portion and of which a cross-sectional area is smaller than the cross-sectional area of the expansion portion. A level difference d satisfies Equation (1): d≥100 μm, satisfies Equation (2): d≤25×Sa+193 μm in a case where an arithmetic average height Sa is equal to or smaller than 50 μm, and satisfies Equation (3): d≤1450 μm in a case where the arithmetic average height Sa exceeds 50 μm, where Sa (μm) is an arithmetic average height of a surface on a central side in the expansion portion and d (μm) is an average value of level differences between a ventilation pipe interior wall and the surface on the central side at at least one of a connection portion between the expansion portion and the inlet-side ventilation pipe or a connection portion between the expansion portion and the outlet-side ventilation pipe.

摘要： A liquid-retainable device includes a device body capable of accommodating a liquid, a first ventilation part, a second ventilation part, a partition part, and a humidification filter. The first ventilation part includes a first hole passing through a wall surface of the device body, and being configured to introduce air. The second ventilation part includes a second hole passing through the wall surface of the device body, and being configured to let out the air. The partition part divides an interior of the device body into a first region, which is a region for accommodating the liquid, and a second region, which is a region for forming an air flow path between the first ventilation part and the second ventilation part. The humidification filter is arranged so as to extend from the first region to the second region.

摘要： The invention relates to a raised ventilation flooring structure (105,106) comprising a first and a second transverse support beam (107,108) extending substantially parallel in a transverse direction T at a predetermined mutual distance W.
The support beams (107, 108) are interconnected via connection profiles (109, 110) to form a grid structure. Carrier profiles with side walls having a number of apertures, are supported with their ends on the support beams (107, 108). A panel with a closed surface is supported on each carrier profile with side edges of adjacent panels being spaced apart to form a ventilation gap (55).
The support beams (107, 108) form elongate collection members that extends along and/or below the side walls of the carrier profiles in the length direction L, below the ventilation gap, to form collection channels (70,100).
An air flow path extends from a space between the side walls of the carrier profiles (50,51), via the apertures (42,44) to the collection channel (70,100) and to the ventilation gap (55) between the adjacent panels (46,48).

摘要： A soffit vent for venting air from an interior of a house having a soffit includes a housing having a front portion and a rear portion. The front portion is coupled to the rear portion and forms an interior volume and a length. The rear portion has an air inlet for coupling to an air source and an outlet for coupling to the front portion. The front portion has a body having an inlet for coupling to the outlet of the rear portion, an outlet port, a length that permits the body to be positioned under a soffit. The outlet port of the front portion is shaped to be positioned adjacent to an outer edge of a soffit, but not under a soffit of a house.

摘要： An acoustically absorptive system for a heating, ventilation, and/or air conditioning (HVAC) system includes a panel assembly. The panel assembly includes at least one acoustic absorptive member and a porous housing disposed about the at least one acoustic absorptive member such that a porous layer of the housing covers the at least one acoustic absorptive member at opposing faces of the panel assembly. A mounting assembly positions the panel assembly in a chamber of the HVAC system such that a gap is defined between a rear surface of the panel assembly and a wall of the chamber, the mounting assembly including one or more channels attached to the chamber.

摘要： A pipe insulation product including a core of insulating material and a laminate surrounding the core and bonded to the core. The core may include an outer surface; an inner surface; and a wall extending between the outer and inner surfaces. The laminate may include a foil or metallized polymeric film sheet, a scrim, a porous media sheet, and a polymeric film sheet bonded together via an adhesive. The laminate may include a closure flap that is configured to adhesively seal opposite ends of the laminate together to form a cylindrical tube with the core enclosed therein. The closure flap may be configured to include a curl that provides a greater closure flap adhesive seal.
