Requirements for a new calculation model

Requirements for a new calculation model to evaluate SPF from lab measurements
The requirements on a new calculation model differs defpending on the aim of the model. In general, three different uses can be identified: Based on lab data understand the consequences of technology choice in comparison with competing heating technologies To understand the consequences of correct sizing of the heat pump To make a correct dimensioning of the heat pump in a specific house
It should also be possible to study three modes of operation, DHW production, heating or combined DHW production and heating.
Based on the models, it should be possible to make comparisons of e.g. LCC and environmental performance of different systems
