| Abstract | One of the conditions for rationalisation of geothermal water use is to improve the geothermal system load factor. In order to fulfill this condition it is advised to target predominantly low-temperature heat customers, or a combination of customers having high temperature installations with customers having low-temperature installations. This enables more effective cooling of municipal heating water and increasing the geothermal system load factor. The authors carried out analyses to determine the influence the combining of high-temperature and low-temperature installations had on improving the utilisation of geothermal energy in a geothermal heating plant. The main purpose of this work was to evaluate the level of influence the application of low-temperature heating systems has on the degree of the geothermal energy in the geothermal heating plant, which supplements the heat distribution network supplying two groups of heat customers having the distinct shares in a heat consumption. These studies are very interesting as concerns the possibility of modernising the existing heating systems by the application of the geothermal unit in a conventional heating plant. |
