Abstract
En bygning med netto-nul-energi producerer over et år lige så meget energi, som den bruger. For at nå dette kræves energisystemer, der er korrekt dimensioneret og spiller godt sammen. Dette projekt undersøger et system, der kombinerer en varmepumpe (en el-drevet enhed, der flytter varme), solceller og en vindmølle. Vi udvikler et program, som for forskellige situationer anbefaler, hvor meget energi der bør komme fra hver kilde, og hvordan komponenterne bør dimensioneres, så behovene dækkes til lavest mulig omkostning inden for givne begrænsninger. Værktøjet afvejer driften af varmepumpen i forhold til lokal sol- og vindproduktion for at finde den mest omkostningseffektive kombination, samtidig med at varme- og elbehov opfyldes. Efter udviklingen tester vi det med gennemsnitsforhold for Danmark for at kontrollere, at tilgangen fungerer efter hensigten.
A net-zero building produces as much energy over a year as it uses. Achieving this goal requires energy systems that are sized and coordinated to work well together. This project examines a setup that combines a heat pump (an electric device that moves heat), photovoltaic solar panels, and a wind turbine. We develop a software tool that, for different situations, recommends how much energy should come from each source and how the components should be sized so the system meets demand at the lowest possible cost under given constraints. The tool balances the operation of the heat pump with on-site solar and wind generation to find the most cost-effective mix while still meeting heating and electricity needs. After building the tool, we test it using average Danish conditions to check that the approach works as intended.
