RESEARCH POLYGONS IN THE CAMPUS OF VSB - TECHNICAL UNIVERSITY OF OSTRAVA (CZECH REPUBLIC) USED TO MONITORING OF ROCK MASS TEMPERATURE CHANGES DURING APPLICATION OF HEAT PUMPS

Original language description

The largest been realized installations of heat pumps in the Czech Rep., where the primary collector of low-potential heat is formed deep wells, is heating complex building of new Auditorium and CIT in campus of VSB - TUO. This building represents two independent functional units. Currently building heats 10 heat pumps with a total output of 700 kW through 110 wells with a depth of 130 m each. To assess the proportions of individual internal and external sources to the overall heat balance, the verification of systems designed for long-term monitoring of the behaviour of the rock massive around the energy used wells and energy storage options have been proposed and gradually implemented two research measuring polygons. They are located in the area of energy utilized wells. Each of the monitoring wells is instrumented with sensors at a certain depth. This article discusses the implementation of research polygons on experience with the excavation of wells using temperature sensors, a data acquisition system and finally outlines the possibilities of evaluating the measurement data. This system is called Large research Polygon. Another researcher constructed a polygon is a Small Research Polygon which is also located on campus. Polygon has two operating wells and nine monitoring wells with a depth of 140 m each. The operating wells are connected to two heat pumps. All the wells are also fitted with apparatus temperature sensors appropriate depth intervals. In the campus is situated the third polygon (ie. Mini), which is provided with a single borehole for heat pump and it is connected with a system of solar panels. The system is reversible and lets in summer to use the waste heat for heating the rock mass.
