Overview

EED is a PC-program for vertical borehole heat exchanger design. Its easy of use, short learning curve, quick calculation times and inherent databases make EED a useful tool in everyday engineering work for design of ground source heat pump system (GSHP) and borehole thermal storage. In very large and complex tasks EED allows for retrieving the approximate required borehole size and layout before initiating more detailed analyses. Even for very small plants it is worthwhile using EED instead of rules of thumb. EED handles configurations from one borehole to large systems with up to 1200 boreholes. Annual base loads may vary between a few MWh up to several TWh!

Features

In ground source heat pump system, heat is extracted from the fluid in the ground connection by a geothermal heat pump and distributed to the building. The fluid is then re-warmed as it flows through the ground. In cooling mode, the process is reversed. This is a renewable, environmentally friendly energy source. This sustainable technique can be used for cooling and heating of houses, cooling of telecommunication switchboards, etc.

EED is based on parameter studies with a numerical simulation model (SBM) resulting in analytical solutions of the heat flow with several combinations for the borehole pattern and geometry (g-functions). Those g-functions depend on the spacing between the boreholes at the ground surface and the borehole depth. In case of graded boreholes there is also a dependency on the tilt angle. The g-function values obtained from the numerical simulations have been stored in a data file, which is accessed for rapid retrieval of data by EED.

Calculation of brine temperatures is done for monthly heat/cool loads. Databases provide the key ground parameters (thermal conductivity and specific heat) as well as properties of pipe materials and heat carrier fluids. The monthly average heating and cooling loads are the input data. different methods of establishing a monthly load profile. A printed output report and output graphical processing are provided.

The program has an easy-to-use interface. The borehole thermal resistance is calculated in the program, using the borehole geometry, grouting material, pipe material and geometry. The borehole pattern may be chosen at will from a database of 800 basic configurations.

The main new features of EED 4: 

  • EED now calculates the response due to any hourly load variation. This means that it handles any loads for cooling, heating, and DHW (Domestic Hot Water), with a resolution of one hour.
    It is quite easy to open an old v3 project and assign any hourly data for any load to investigate the effect of base or peak loads.
  • EED v4 uses fast multi-core cpu computation. EED can even use the GPU (graphics processing unit) to speed up calculations, e.g. it is possible to solve for 100 years of hourly data in just 4
    seconds on a $300 graphics card (Radeon RX 480).
  • EED v4 is more than 50 times faster than EED v3. An optimization that took a few minutes on EED v3 only takes a few seconds using EED v4 for monthly load values.
  • EED v4 will also find more solutions (especially for cases with cooling loads) compared to v3 for the optimization
  • A lot of smaller improvements.
  • The user interface now supports 34 languages: English, Arabic, Basque, Bulgarian, Catalan, Chinese (simple), Czech, Danish, Dutch, Estonian, Farsi, Finnish, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean, Latvian, Lithuanian, Polish, Portuguese, Romanian, Russian, Serbian (Serbian Latin), Cyrillic (Serbian Cyrillic), Slovene, Slovak, Spanish, Swedish, Turkish, Vietnamese

EED_Languages.zip
Download this zip-file and extract the files to the directory where the language folder is located (e.g. C:Program FilesBloconEED_3Languages) and replace the old files. Choose language in EED (menu item Settings/Language).

Help needed for translation into other languages

We offer a free license of EED Multi-lingual  if you make a valid translation into a new language (add a column in EED_Languages_xls.zip). If you wish to contribute, please contact us first in case of that no other is currently working on it.

At the moment, we need translations made for the following languages:
Indonesian, Hindi, Urdu.
(we do not need other languages at the moment)

(There are about 1100 words to translate.)

How to create files for a new language

New language files can easily be created and edited. There are three files for the menu text, the input dialogue text, and the output text:
Menu text: Lang_menu_***.txt
Input text: Lang_in_***.txt
Output text: Lang_out_***.txt

The “***” should be replaced by the ISO 639-2 Code, see
http://www.loc.gov/standards/iso639-2/php/code_list.php

E.g. the Swedish files are named
Lang_menu_swe.txt
Lang_in_swe.txt
Lang_out_swe.txt

If you create new language files please consider to email these to info@blocon.se and we will make these available to others.

Create/Add/Edit languages in menu item Settings/Options, see below.

”EED on the web”

Apart from the standard desktop version, EED v4 is also available as an add-on (“EED on the web”) which runs on our dedicated server from any operating system and/or device with an HTML5-compliant web browser, such as IE10/11, Chrome, Safari, Firefox, Opera, etc. It supports PC, Mac, iPad, iPhone, Chromebook, Android and many other popular devices. You can even run it from any smart-TV connected to the Internet.

=> For more info, see manual: EED on the web

There are many advantages running EED on a dedicated server:

  • Extreme calculation performance. We use very powerful cpu:s and gpu:s allowing quick simulations and optimizations for both monthly and hourly values for loads.
  • You dont have to install/update EED. It has always the latest version.
  • Access it from anywhere via a web browser on your PC, Mac, IPad, IPhone, smartphones, tablets, TV:s, etc.
  • Share your project files on the server with colleagues. There can even be simultaneous concurrent users accessing the server.
Training
  • Geotrainet uses EED in their courses ”Training for designers” on several locations in Europe. Please see their course calender.
  • Holymoor Consultancy Ltd (UK) offers courses and training in EED. Please see their course calendar for “open” courses, or contact Holymoor Consultancy directly for bespoke internal training.
  • Courses (usually in Swedish) given by www.geoenergicentrum.se and www.emtf.se.
