Program for Heat and Flow Calculations of Geothermal Heating Plant in Cooperation with Heating Network

Abstract

Authors introduced practical solutions for heat distribution in municipal heating network, supplied from geothermal heat plant operating with geothermal heat exchanger. Heat and flow calculations include: geothermal water extracting system, geothermal heat exchanger and system of geothermal energy utilization consisting of peak load boiler, high and low temperature users. Computer program simulates variability of many parameters, regarding to users requirements and localization. It provides the choice of the most effective solution after taking into consideration following criteria: maximum utilization of temperature difference and minimal number of bypass used in a system. Program can find application for installations in design stage, existing or being modernized. This work illustrates the influence of floor heating on effectiveness of geothermal energy utilization, and the influence of heating network temperature on effectiveness of geothermal energy utilization.
