GEODIM, Version 2.1: Users manual (English units version).

摘要

The GEODIM computer program has been developed as a joint project of the University of Lund, Lund, Sweden and the Washington State Energy Office (WSEO). The development of GEODIM was originally begun in response to the need to optimize the Lund, Sweden geothermal system. This system is the world's largest heat pump geothermal system having an output of 50MW thermal. The 50MW of output provides a significant percentage of the base load thermal demand of the Lund district heating system. When approached by WSEO, the University of Lund agreed to expand the capability of the program and make it equally usable for the optimization of direct use system's which do not employ heat pumps. In addition, the university prepared examples of how the program can be used. The program has been extensively tested against data from the Lund system which now has five years of operating data. The program has proved itself to be a valuable tool for optimizing piping systems and system operation. Although the program was originally designed for the optimization of geothermal systems employing both production and injection wells, it can be just as successfully used for any system using a water source, be it surface water or waste water from industry or effluent from a sewage treatment plant.
