Comparing new control concepts for heat pump heating systems on a test bench with the capability of house and earth probe emulation.

Summary

A test bench for dynamical tests on a brine-to-water heat pump is presented. The test bench at the Measurement and Control Laboratory of ETH allows the comparison of heat pump control concepts under real conditions. The thermal behaviours of a fictitious house as well as of a fictitious earth probe are emulated for a real heat pump installed at the test bench. The weather is also emulated using synthetic weather data. Since these conditions are reproducible, the controllers can be compared among each other equitably under the same conditions. A new control concept for heat pumps is also introduced, which makes use of weather forecast data to optimize the heat distribution during the day. The results of the comparison between a conventional relay-type controller and the new model predictive controller show that with the new controller concept the heating costs are reduced by 10%.
