Research project

cpExakt – Measuring of heat capacity of liquid heat carriers

In this project a calorimeter was built for the measurement of the specific heat cp of heat transfer fluids with a measurement uncertainty of ±0.3 %.

The apparatus will be used for quality assurance at the SPF and is available for measuring fluids of third parties as well. This brings significant advantages for manufacturers and suppliers of heat transfer fluids that can deliver physical properties of their fluids with higher accuracy, for facility operators of large systems that can survey the energy balance of their systems with higher accuracy, and for researchers and developers that may determine more accurately the energy balance of prototype systems that use heat transfer media other than water.
