Analysis and optimization of a heat pump system coupled to an installation of PVT panels and a seasonal storage tank on an educational building 2020 Access copy available to the general public Unrestricted A water-water solar-assisted heat pump (SAHP) is projected on an under construction academic building at the University of Zaragoza (Spain). It integrates a heat pump heating system with photovoltaic/thermal collectors and seasonal storage. Because of its innovative design, considerably higher performances than a conventional type air-source heat pump are expected. This paper shows the simulation of the system performed in TRNSYS, a graphically based software used to simulate the behavior of transient systems. In addition, starting from the current design of the energy system, different sensibility analysis are simulated in order to study alternative configurations of the heating system. The solar coverage of the current installation design is about 60% and the expected savings yield to a payback period of 15, 4 years. Three alternative configurations are proposed in this work, reaching up to around 98% of solar coverage. The study results show the technical and economic feasibility of the heating installation based on a solar assisted heat pump with implementation of seasonal storage in an educational building located in a middle latitude. info:eu-repo/grantAgreement/ES/UZ/OTRI-2019-0566 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.879 2020 CONSTRUCTION & BUILDING TECHNOLOGY 9 / 66 = 0.136 2020 Q1 T1 ENGINEERING, CIVIL 9 / 136 = 0.066 2020 Q1 T1 ENERGY & FUELS 36 / 114 = 0.316 2020 Q2 T1 1.737 2020 Building and Construction 2020 Q1 Mechanical Engineering 2020 Q1 Electrical and Electronic Engineering 2020 Q1 Civil and Structural Engineering 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Martínez-Gracia, A.
