FOUR INNOVATIVE SOLAR COUPLED HEAT PUMP SOLUTIONS FOR BUILDING HEATING AND COOLING

摘要

Despite the huge primary energy consumption associated with heating and cooling (H&C) demand in EU building stock, the share of installed renewable H&C solutions is still marginal (i.e. 5%). In order to speed up a transition towards the widespread application of renewable H&C in buildings, innovative solutions are designed to compete against traditional solutions. SunHorizon project aims to demonstrate the potential for a user-friendly and cost-effective solution based on an optimized design and combination of commercial innovative solar technologies (thermal or/and PV) and Heat Pumps (HP). This paper presents how different technologies (two solar panels, three HPs and thermal storage) have been coupled in four different Technology Packages (TPs) to satisfy H&C demand of both residential and tertiary buildings. Preliminary thermo-economic TRNSYS simulation results are presented about four demo sites in Latvia, Germany and Spain, to demonstrate such innovative solutions able to cover up to 80% of H&C demand with a reduction of greenhouse gas (GHG) emissions up to 70%.
