THE EXPERIENCES FROM CONSTRUCTION AND OPERATIONS OF THE EXPERIMENTAL UNDERGROUND HEAT STORAGE RESERVOIR IN THE CAMPUS OF VSB - TECHNICAL UNIVERSITY OF OSTRAVA
Abstract
VSB – Technical University of Ostrava has a possibility to investigate changes in the rock massive during operation of heat pumps. Our new University Hall is heated up by the heat pumps. This object is the biggest building in the Czech Republic and in the Central Europe which uses this type of the system. Monitoring boreholes are situated in the area of heat pumps boreholes. They are equipped with heat sensors which monitor temperature changes in rock massive during the heat pumps operati on. This locality is called Large Research Polygon and the main goal is investigation of changes in the rock massive due to utilization of this heating system. Second locality is called Small Research Polygon. It is situated near The University Hall and consists of two heat pumps boreholes and nine monitoring boreholes in the surroundings. All of these boreholes are equipped with temperature sensors (similar like the Large Research Polygon) used for monitoring of heat changes in the rock massive during heating (accumulation of heat that comes from air conditioning in summer) and during cooling (pumping of heat from the ro ck massive by heat pumps in winter). The main goal is to verify the possibilities of this system. The authors have many experiences during the realization and operation of the Research Polygons placed at VSB – Tec hnical University of Ostrava. These experiences can be used for future constructions of similar research objects. This ar ticle will discuss the possibilities of realization and construction of Polygons and show some results.
