Parametric simulation of a solar coupled heat pump system

Increasing studies about climate change and CO 2 emissions levels, as well as international agreements, are leading toward a decarbonization of the overall energy system. Heating and cooling for civil and residential application covers 55% of EU primary energy demand. On this frame the solar coupled technologies offer interesting perspectives in terms of primary energy savings and emissions reduction. The SunHorizon project (H2020 Project GA818329) aims to analyse the performance of building-integrated solar and HPs solutions. Within this project a parametric study showing the performance of a sun-coupled system that integrates solar technology and innovative thermally driven heat pump was carried out. The simulations, performed by commercial software IESVE and TRNSYS, show promising results by achieving a remarkable range of primary energy savings (from 18% to 57%) and greenhouse gas emission reduction (from 24% to 57%).
