Final Report – Part 2 Annex 32: Economical heating and cooling systems for low energy houses
System solutions Multifunctional heat pump systems for the application in low energy houses The report gives an overview of marketable heat pump system solutions applied in low energy houses in the participating countries of IEA HPP Annex 32. In low energy houses, loads change significantly, in particular the space heating needs are notably reduced, and the share of DHW increases. Moreover, mechanical ventilation may be required to guarantee the necessary air exchange due to the air-tight building construction, and in recent years market development show an increasing integration of a comfort cooling option in the system layouts.
