ENERGY EXTRACTION FROM ROCK MASS USING VERTICAL HEAT EXCHANGERS

Popis výsledku v původním jazyce

The aim of the verification study was to determine and analyse the temperatures of the rock mass, specific heat capacities and specific energies extracted from the rock mass by two types of vertical heat exchangers namely single U-tube heat exchanger (U1) and double U-tube heat exchanger (U2). The exchangers were used as low-potential energy source for heat pumps. Design and operating parameters influencing the process of heat transfer between the rock mass and the heat-transfer fluid were also evaluated. The results demonstrated the advantages of using double U-tube heat exchanger U2 both in terms of its impact on the performance factor of the heat pump, and in terms of specific heat outputs and specific energies extracted from the rock mass. The average daily temperatures of the heat-transfer fluid in heat exchanger U2, specific heat outputs and specific energies extracted from the rock mass were higher by 4,5%, 26,8% and 25,6%, respectively than in the heat exchanger U1.
