VERTICAL GROUND HEAT EXCHANGERS - LOW-TEMPERATURE ENERGY SOURCES

Popis výsledku v původním jazyce

The most widely used types of ground exchangers in Europe, single (A) and double (B) U-tube exchangers, installed in 113 meters deep boreholes were verified during our research. The monitored parameters included the temperatures of heat carrier fluids, thermal resistances, specific outputs and extracted energies of vertical rock exchangers used as low-temperature energy sources for heat pumps. It is apparent from the results of the verification that the single U-tube exchanger was more effective than the double U-tube exchanger in terms of the monitored parameters. Temperatures of the fluids were higher for exchanger B and their distribution was more favourable. However, differences in average temperatures were only 0,35 K The specific heat outputs per 1 m(2) of heat exchange surface area and specific energies extracted from the mass were higher at exchanger A than at B by 11,17 W and 370 kI/m(2).day, respectively.
