Summary

The energy and efficiency performance of 16 large heat pump systems was assessed in detail based on multi-annual measurement campaigns. For the heat pump systems, seasonal performance factors from 2.3 to 6.1 kWhtherm/kWhel have been achieved. The use of ground-coupled reversible heat pumps for cooling is also an efficient and sustainable approach to cooling building. Here, the relativity high supply water temperatures of 16 to 20°C allow for cooling with good energy efficiencies.
