Testing of large-scale heat pumps Fraunhofer IEG

One of the key problems regarding the roll-out of large-scale heat pumps is limited high-quality testing capacity. Setting up accredited test beds for applications beyond the 400 kW limit of the KEYAMRK certificate is complex and costly, putting manufacturers off establishing such labs themselves.

Yet high quality testing for large-scale heat pumps is necessary since potential customers might not have enough faith in devices or will not get aware of the eligibility of devices for grants. In Germany heat pumps in this class will only be publicly listed for BAFA funding with efficiency being measured according to the standards of ISO 17025.

Therefor the Fraunhofer Research Institution for Energy Infrastructures and Geothermal Systems (IEG) has developed a brand-new lab that allows high-quality testing of large-scale heat pumps up to the MW class. Temperature-wise the test environment can emulate any common heat sources and heat sinks of heating, district heating and industrial applications. We can offer bespoke measuring services for our customers for product certification or any research and development projects. These can be linked up with our own research activities along the entire value chain of energy system transformation including analysis, operation, and planning of sector-coupled electricity, gas and heating grids, drilling and geotechnologies, energy and process engineering, energy economics, georesources, and geosciences, storage systems, and hydrogen infrastructures.
