Multi-source/sink Energy Sub-system

MES will be designed according the functionality of an invertible heat pump group able to exploit different thermal source/sink: PV/T-PCMs, air (outdoor and waste heat) and ground. The heat pump will be assumed as a standard water-to-water technology, electrically driven to exploit the PV power, reversible to satisfy both heating and cooling requirements, and integrated with PCM thermal storage foreseen by user-side (heating/cooling floor/wall, UTES, PV/T-PCM). Compact air heat exchanger (fin & tube), Flat-Panel ground heat exchangers and biomimetic PV/T-PCM heat discharge system will provide a multi-source thermal harvesting opportunity, whose tailored exploitation will have to be controlled in real-time by a control unit (WP4) to optimise and match energy supply and demand, also considering the weather conditions. This will be completed under task 3.2.
