Nov. 26, 2007 – The present development of the heat pump market is extremely interesting: in regions such as Japan and the US, where the market is dominated by air-to-air units, ground-coupled systems are obtaining an increasing share, while in regions such as Central and Northern Europe, which are dominated by groundsource systems, air-source systems have an increasing market share.
Additionally, due to improved thermal insulation, cooling, which is common in Japan and the US, is becoming more interesting in Central and Northern Europe too. This requires an increase in efficiency of units and systems, not only in full-load operation, but also in part-load operation, which is more important for a high SPF than the full-load data alone.
