# Ground Heat Exchanger Design Tool
A package with the novel capability of automatically selecting ground heat
exchanger configurations based on polygonal land constraints. This package
contains advanced methods that are the first of their kind. The results are
validated against the world renowned `GLHEPRO` (Cook 2021).
The Ground Heat Exchanger Design Tool (DT) is a Python package that can
quantify the short- and long-term thermal interaction in a ground heat exchanger
(GHE). The long-term thermal response g-functions are computed live-time with
[pygfunction][#pygfunction]. The DT contains a fast monthly hybrid time step
simulation for prediction of heat pump entering fluid temperatures over a design
life. The DT can vary the size (or borehole height) of a specified borehole field
to ensure the heat pump entering fluid temperature remains within specified
bounds. DT contains a novel borehole configuration selection algorithm.
## Novel Design Algorithms
DT contains a novel design methodology for automated selection of borehole
fields. The advanced methodology performs optimization based on a target
drilling depth. An integer bisection routine is utilized to quickly search
over a unimodal domain of boreholes. DT can consider available drilling and
no-drilling zones defined as polygons.
The selection process shown below is performed in less than half a minute on an
11th Gen Intel Core i9-11900K @ 3.50GHz. Refer to `Cook (2021)` for more
information.
## Requirements
`ghedt` requires at least Python 3.7 and is tested with Python 3.7 and 3.8, and is dependent on the following packages:
- pygfunction (>=2.1)
- numpy (>=1.19.2)
- scipy (>=1.6.2)
- matplotlib (>=3.3.4)
- coolprop (>=6.4.1)
- pandas (>=1.3.2)
- openpyxl (>=3.0.8)
- opencv-python (==4.5.4.58)
## Quick Start
**Users** - Install `ghedt` via the package installer for Python ([pip][#pip]):
```angular2html
pip install ghedt
```
**Developers** - Clone the repository to via git:
```angular2html
git clone https://github.com/j-c-cook/ghedt
```
See [installation](https://github.com/j-c-cook/ghedt/blob/main/INSTALLATION.md)
for more notes on installing. See [ghedt/examples/](https://github.com/j-c-cook/ghedt/tree/main/ghedt/examples)

## Acknowledgements
The initial release of this work (`ghedt-v0.1`) was financially supported by the U.S. Department of Energy contract DE‐AC05‐00OR22725 through research subcontracts from Oak Ridge National Laboratory. Dr. Jeffrey D. Spitler was integral to the successful development, mostly through advice and feedback.
