Abstract
The growing market penetration of heat pumps indicates the need for a performance test
method that better reflects the dynamic behavior of heat pumps. In this contribution, we developed
and implemented a dynamic test method for the evaluation of the seasonal performance of heat
pumps by means of laboratory testing. Current standards force the heat pump control inactive by
fixing the compressor speed. In contrast, during dynamic testing, the compressor runs unfixed while
the heat pump is subjected to a temperature profile. The profile consists of the different outdoor
temperatures of a typical heating season based on the average European climate and also includes
temperature changes to reflect the dynamic behavior of the heat pump. The seasonal performance
can be directly obtained from the measured heating energy and electricity consumption making
subsequent data interpolation and recalculation with correction factors obsolete. The method delivers
results with high precision and high reproducibility and could be an appropriate method for a fair
rating of heat pumps.
