The complex system for the rock massif measurement of temperature parameters

Abstract

This paper brings information about research activities of temperature measurement in boreholes. The described research is focused on unique geothermal boreholes system used for heat pumps applications. The first part of the contribution deals with long time measurement of the temperatures in boreholes used in heat pump installation. A system for monitoring and evaluation of temperatures in measurement polygon is presented. The second part is focused on measurement of thermal profile of the borehole. The paper does not evaluate geothermal properties of the boreholes but it describes the measurement issues and methods.
