Solar Hybrid PVT Coupled Heat Pump Systems Towards Cost-Competitive NZEB
Abstract
The high energy consuming building sector needs to meet both electricity and heat demands. In a nearly zero energy building scenario most of the consumed energy would be generated locally by means of renewable solutions that nowadays seem not to provide an attractive cost-competitiveness. Solar based technologies tend to be the most promising ones, but for high densely populated and restricted areas the common photovoltaic or thermal single approaches are not efficient enough. The current work is focused on the analysis of a dual use of solar resource by means of hybrid collectors and their smart combination with heat pumps through predictive control strategies towards entire-lifetime feasible solutions for zero energy buildings. A techno-economic comparative analysis of the proposed system versus market standard solutions and different solar coupled heat pumps has been carried out for different case studies. The results show that the PVT dually coupled HP solution could be feasible and cost-competitive in different European climates.
