1. Analysis Calculation of Borehole Thermal Resistance The Thermal Resistance is calculated at the time of the first fluid exchange in the BHE after the heating power is switched on It is your task to specify this point of time The program suggests a time based on the volume and the flow rate _ Vols Volg aa V with Vols Volume of tube Vol Volume of TRT device V Flow rate if a variable flow rate is given the program uses an averaged value The equitation used to calculate the Thermal Resistance R is with Q Heat flow A logarithmic mean temperature difference at the time of fluid exchange This equitation looks quite simple but we want to explain some details here too Logarithmic mean temperature difference The logarithmic mean temperature difference AS is defined as Uy Ur AU in 5 1 Ur Vy with Sy Temperature in Temperature out y Temperature of undisturbed underground Heat flow The Heat flow Q is defined as Qn gt mit Q Heating Power W H Tube length m Heating Power The Heating Power Q is calculated by using the temperature difference Q pCpV dy Up with 2011 GeoLogik Software GmbH 20 GeoLogik TRT 2 2 2 p Density of fluid kg m Cp Specific heat capacity of fluid kJ kg K V Flow rate of fluid m s When calculating the Thermal resistance R the program uses the flow rate at the time of the
