GHE Soil Parameter

- [source code]

Create a SoilParameter object that can be used to customize the soil and grout 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

• conductivity

A number for the soil conductivity in W/m-K. (Default: 2.3).

• heat_capacity

A number for the volumetric heat capacity of the soil in J/m3-K. (Default: 2,343,500).

• temperature

A number for the undisturbed annual average soil temperature in degrees Celsius. If unspecified, this value will automatically be replaced with the average EPW temperature before simulation of a District Energy System (DES). Alternatively, if this component is used with the "DF GHE Designer" component, it will be 18.3C.

• grout_conduct

A number for the grout conductivity in W/m-K. (Default: 1.0).

• grout_capacity

A number for the volumetric heat capacity of the soil in J/m3-K. (Default: 3,901,000).

Outputs

• soil

A SoilParameter object that can be plugged into the "DF GHE Designer" component in order to customize soil 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.
