5 Geothermie zinvol voor schoolgebouwen?
KA Veurne Effecten van langdurige vakantieperiodes op de bodembalans? Het gebruiksprofiel van een school is immers vrij specifiek Juli-Augustus Daling bron T° Daling COP

6 Geothermie zinvol voor schoolgebouwen?
KA Veurne Geschiktheid van afgiftesystemen? Variërende lokaalbezetting: snel wijzigende vraag & comfort-eis Trage afgifte, laag verwarming-/koelvermogen

16 Overzicht De Wending Turnhout KWO systeem Hoge en lage temperatuur warmtepomp (180 kWth kWth) Zonnecollectoren (63m², vacuümbuis) 2 gasketels (2 x 311 kWth) BKA+ vloerverwarming Radiatoren Luchtgroepen Case zonnecollectoren: overschot van SWW productie gebruiken voor regeneratie bijvoorbeeld. Stijging van COP? Case split BEO: This drycooler operation mode does not attempt to balance the yearly energy injection or extraction as it would be the case in many HGSHP systems with a single bore field/storage, but tries to maximize seasonal energy storage. The system is more dependent on meteorological conditions (warm winter, followed by a hot summer can result in free cooling failure...) The electricity consumption of the drycooler will increase due to larger fans The initial cost of the drycooler will be higher

17 Efficiënt gebruik van geothermische installatie in woonzorgcentra en rusthuizen?
Combinatie hoge en lage temperatuur verwarmingssystemen Warmtepomp vs. gasketel BKA/VVW vs. radiatoren Energiebesparing
