CLGS
is ground heat exchanger design program for residential applications. Written
by IGSHPA executive director Dr. Jim Bose, CLGS calculates the proper sizing
of the ground heat exchanger, heating, cooling and water heating costs,
peak heat and cooling demands, loop pipe lengths, and pressure drops. The
user must input the building loads, design area, heat exchanger configuration,
pipe size and type, and heat pump capacities. CLGS also provides a comparison
of operating costs of gas, LPG, electric heating / cooling systems and GHP
systems.
CLGS is menu-driven and produces concise, comprehensive print-outs. It handles both horizontal and vertical systems, and provides initial values for entering minimum and maximum water temperatures. The program requires an IBM or compatible computer, and comes with a comprehensive user's guide. A demonstration disk is available; should you decide to buy the full program, the price of the demonstration disk will be applied to the cost of the program.
GLHEPRO is now available in three different versions:

- Capability to model rectangular borefields up to 900 boreholes.
- Sizing of ground loop heat exchanger and supplemental heat source/sink as part of a hybrid ground source heat pump system.
- More accurate calculation of borehole thermal resistance, including thermal mass effects.
- Revamped fluid property routines. The working fluid can now be specified in terms of composition and concentration.
- Addition of double U-tube and concentric tube heat exchangers.
- Marked improvement of output reporting. Users can specify what information is reported, and have the option of creating a Microsoft Excel-compatible .CSV file.
- International ground temperatures are available for several locations, and users may enter additional locations.
- Heat pump database has been greatly expanded.

GLD's flexible "Geothermal Design Studio" concept employs a modular format that offers tremendous benefits. For example, multiple projects can be studied and/or compared simultaneously. Both detailed and concise reports are available from all Modules. The straightforward reports not only provide a system for neat and accurate internal record keeping but they also can be used to present a professional image to clients. Beyond the practical concerns of system optimization, GLD offers designers a user friendly tool to complete complex designs,
The unique Design Studio™ workspace offers exceptional access to all the project-specific data, design and reference tools (a variety are included in program) necessary to create, modify, and optimize projects. Multiple projects can be compared simultaneously! User-defined customization and the following interconnected modules provide flexibility throughout the designing process:
Heat exchangers, loads, heat pumps, reports, help files, and additional tools have never been this accessible, interactive, or easy to use. Vertical borehole, horizontal, and surface water (pond, lake, etc.) models employed in Ground Loop Design's modules have undergone extensive research and verification establishing their validity for hassle-free long-term operation. In addition, the software includes specialized loads models to handle both rapid "average block" estimates, as well as a more complete zone analysis. In the latter, any type of heat pump, including water-to-water, may be matched automatically to zones in a fully customized manner. An advanced heat pump module and other design tools complete the Design Studio package. Ground Loop Design also facilitates communication with its expansive project and loads reporting capabilities.
Edition Capabilities and International Features
Ground Loop Design also includes a variety of international features, such as metric/English unit conversion and international language versions that all use the same file type. This is vital for any designer wishing to get involved in the rapidly growing international market. Currently, Ground Loop Design is available in two English language versions: Premier and Express. Ground Loop Design Professional includes all program features, while the Limited Editions offer a partial selection of functionalities. Foreign language versions are available, also.
English, Korean and Chinese language versions are immediately available. Specific languages are available upon request. A Demo version of Ground Loop Design Professional is available free of charge. Windows 95/98/NT/ME/2000/XP required with 50MB of disk space. Visit www.groundloopdesign.com for more details. The built-in Studio Link™ system automatically recognizes and updates all relevant modules when a design change is made in either a loads or design module. Design optimization and parameter comparisons have never been easier. Metric/English units and a variety of professional reports complete the package.
PC Programs for Dimensioning of Heat Extraction Boreholes:
| PC Programs for Dimensioning of Heat Extraction Boreholes ( #33010) | $300.00 |
This set includes eight different programs for commercial applications, all written by Per Eskilson and Johan Claesson of Sweden’s Lund University. Brief descriptions of the programs follow below:
- TFSING: Calculates the lowest or highest fluid temperature (mean value of the inlet and outlet temperatures) for a single borehole.
- TFMULT: Calculates the lowest or highest fluid temperature for a multiple borehole system (or a single borehole).
- TFSTEP: Calculates the fluid temperatures for a single or multiple borehole system at an arbitrary time. The heat extraction rate is given by 12 steps or less with arbitrary lengths. The 12 steps are repeated cyclically after the period of time, normally one year.
- DIM: Calculates by iteration the required active borehole length for a single borehole or a multiple borehole system when the outlet fluid temperature is prescribed at a certain time, or when the lowest or highest temperature during the year (or any other period) is prescribed.
- INOUT: Calculates simply the inlet and outlet temperatures when the mean fluid temperature is given.
- QSURF: Calculates the heat flow through the surface at the radius from the center of a single borehole.
- QTOTSURF: Calculates total heat flow through the ground surface for a single borehole.
- GRWATER: Calculates the steady-state temperature at the borehole wall for a single borehole, when the heat extraction is influenced by groundwater filtration.
Knowledge of annual building energy requirements and building loads is required for these programs, and conversion sheets are supplied. These programs are compatible with thermal units found in EPRI’s Soil and Rock Classification for the Design of Ground-Coupled Heat Pump Systems. The programs will run under MS-DOS on IBM and compatible computers, and come complete with a user’s manual.
