GHE Pipe Parameter

- [source code]

Create a PipeParameter object that can be used to customize the pipe properties within a Ground Heat Exchanger (GHE) sizing simulation.

The output of this component can be used with either the "DF GHE Designer" component or the "DF GHE Thermal Loop" component.

Inputs

• inner_diameter

A number in Rhino model units (eg. Meters, Feet, etc.) for the diameter of the inner pipe surface in meters. (Default: 0.0216 meters).

• outer_diameter

A number in Rhino model units (eg. Meters, Feet, etc.) for the diameter of the outer pipe surface in meters. (Default: 0.0266 meters).

• shank_spacing

A number in Rhino model units (eg. Meters, Feet, etc.) for the spacing between the U-tube legs, as referenced from outer surface of the pipes in meters. (NOT referenced from each pipe's respective centerline). (Default: 0.0323 meters).

• conductivity

A number for the conductivity of the pipe material in W/m-K. (Default: 0.4).

• heat_capacity

A number for the volumetric heat capacity of the pipe material in J/m3-K. (Default: 1,542,000).

• arrangement

Text for the specified pipe arrangement. Choose from the following options. (Default: SingleUTube).

* SingleUTube

* DoubleUTubeSeries

* DoubleUTubeParallel

Outputs

• pipe

A PipeParameter object that can be plugged into the "DF GHE Designer" component in order to customize pipe properties of a GHE sizing simulation. It can also be plugged into the "DF GHE Thermal Loop" component to perform a similar role in a District Energy Simulation (DES) of a loop with a ground heat exchanger.
