Summary
Researchers at Germany's Fraunhofer Research Institution for Energy Infrastructures and Geothermal Systems (IEG) investigated how solar thermal-assisted heat pumps or air sourced heat pumps powered by ground-mounted photovoltaics (PV-ASHP) may be combined with pit thermal energy storage systems (PTESs) in a district heating network (DHN) under different scenarios and found that PV-ASHP systems may offer more advantages in densely populated areas.
Using open-source Python software, the group conducted a series of simulations on eastern Germany assuming different charging options for the PTESs. They also considered total system cost including Opex and Capex, as well as system designs and the network’s storage capacity during the operation. “The model separates the hydraulic and thermal calculation and builds up a multi-stage process to consider temperatures inside the network and the PTES,” it specified.
