A first ventilation duct line has a first portion having a first sectional area, a second portion having a second sectional area larger than the first sectional area, and a third portion having an inclined inner face connecting the first portion and the second portion to each other. Further, there is a second ventilation duct line having an opening portion positioned on an inner side of the first portion of the first ventilation duct line.

A vibration damper for a fuel conduit of a gas turbine combustor includes a mounting portion and a damping portion. The mounting portion is secured to the fuel conduit, and the damping portion includes a stack of damping washers, a bushing on top of the stack of damping washers, a spring clip secured around the stack of damping washers and the bushing, and a shoulder bolt disposed through the bushing and the stack of damping washers and engaged to the mounting portion.

A method of fabricating a conduit comprises steps of attaching a first tubular-outboard-ply end of a tubular outboard ply to a first inner collar portion of a first collar with a third weld and attaching a second tubular-outboard-ply end to a second inner collar portion of a second collar with a fifth weld. The method additionally comprises steps of interconnecting the first inner collar portion and a first outer collar portion of the first collar with a first weld and interconnecting the second inner collar portion and a second outer collar portion of the second collar with a sixth weld. The method also comprises attaching a trimmed first corrugated-inboard-ply end to the first outer collar portion with a second weld, attaching a trimmed second corrugated-inboard-ply end to the second outer collar portion with a fourth weld, and communicatively coupling a first sensor with an interstitial space.

A heating, ventilation, and air conditioning (“HVAC”) system includes an evaporator coil and a compressor fluidly coupled to the evaporator coil via a suction line. A condenser coil is fluidly coupled to the compressor via a discharge line and fluidly coupled to a metering device via a liquid line. A charge compensator is fluidly coupled to the liquid line via a connection line. A charge compensator re-heat valve is disposed in the connection line.

The present inventive concept includes a duct system and method for using same to map and locate ducts. A preferred embodiment of the duct system includes a duct, a plurality of electronic information modules and an oversheath at least partially covering the plurality of information modules and fixing the information modules to the duct. The plurality of information modules are configured to emit a positional signal to enable location of the information modules and associated duct(s) and/or mapping of the duct system.
