Cascaded Uses of the Geothermal Water at the University of Oradea, Romania

Abstract

The Oradea reservoir and the geothermal water well inside the University campus, as well as the current utilization of the geothermal water at the University of Oradea are briefly discussed in the first part of the paper. A new building is at present under at the University campus and future developments are already planned and approved by the University Senate. The possibility to supply the total heat demand with the available geothermal water is considered and a new system is proposed for this purpose. The methodology used for the heat supply calculation is briefly presented, together with the results. The paper shows the need for cascaded uses in order to increase the utilization efficiency and to improve the economics. It also shows the environmental advantages of geothermal energy utilization, as compared to the classic heating schemes currently used in Romania.
