National Project:


SP, the Swedish National Testing and Research Institute is the national team leader of Sweden. Chalmers University of Technology as well as the manufacturers Thermia Värme AB, NIBE AB and
IVT AB are members of the national team.

Ground-source (B/W) heat pumps is the most common heat pump type in Sweden. Therefore, the Swedish project was concentrated on this heat pump type in the beginning. After defining the boundary of the system that should be included in the proposed test and calculation method, a first draft of test method was outlined. Thereafter, an alternate operating ground-source heat pump system depicted in Fig. 12 was measured extensively according to the different European standards EN 14511, EN 255-2, EN 255-3 and M/324. The draft test method was also evaluated experimentally.

Due to the Swedish building regulations exhaust-air heat pumps are also popular in Sweden. Systems with combined space and domestic hot water heating are common for this market segment. In Sweden, a national testing method has already been developed in the end of the Eighties. However, this method was limited to Swedish circumstances regarding climate and regulations, and also to a certain range of house size. In the later part of the Swedish project, the integration of test procedures and calculation methods for exhaust air systems was performed as well. To start with, this was based on the analysis of existing measurements.

Conclusion of the experience from the measurements have been introduced in the proposal of a test procedure described which is outlined for ground-source, outside air-source and exhaust air-source heat pumps and further developed to an adequate calculation method based on the definitions of the Annex 28. Finally, parts of the proposed test method were evaluated experimentally with an exhaust-air heat pump in simultaneous combined operation.
