Abstract: In future highly energy-efficient buildings, heat pumps will play a key role. Hence, annual efficiency calculation and optimization by means of simulating heat pump heating and cooling systems are very valuable, especially if building and building technology are coupled. This paper gives an overview on existing models and a categorization with pros and cons in terms of generic approach, validation and quality of documentation. Most common are simple performance map based models for seasonal performance factor calculations, sometimes improved by adding PT1 inertia for heating up and cooling down. Especially for heat pump design, refrigerant cycle based physical graybox models can encourage new developments.
