Abstrakt

The dominant source of energy in the hot water boiler house Stred I. in Velky Meder is geothermal energy, which is drawn from the VM -1 well, which was drilled in its courtyard in 2015. Based on documents and personal inspections of this boiler room, I created a geothermal circuit scheme of this hot water boiler room, where the experimental measurements took place. Part of this paper is a diagram of the geothermal circuit, a comparison of measured values within a selected characteristic day for summer and winter operation in 2020. Finally, the operation of the usage of geothermal energy in the hot water boiler room Stred I. is evaluated on all these indicators.
