ASSESSMENT OF THE INFLUENCE OF BOREHOLE HEAT EXCHANGER DESIGN ON A GROUND COUPLED HEAT PUMP SYSTEM

Abstract

The paper presents the general concept of a ground coupled heat pump system that could be installed in a building belonging to University of Oradea. A short description of the consumer, together with base load and peak load energy consumption around the year, are also shown in the first part of the paper. Then, all design elements for the borehole heat exchanger (BHE) are presented and several scenarios are set. For each of them a simulation of mean fluid temperature is made for a time period of 20 years. Finally, results are analysed, and each case is discussed showing its advantages or disadvantages. At the end, conclusions are set.
