Abstract:
With the recent development of new controllers for heat pump systems, there is a need to test and compare these controllers in a realistic and reproducible environment. This can be done using a semi-virtual test-bench with a simulation environment that is calibrated with in-situ measurements. A real ground source heat pump (GSHP) is connected to the test bench that emulates the building and the boreholes. The test can thus be carried out under dynamic conditions: dynamic weather conditions are used as well as simulated building, floor heating and boreholes. In this study, the developed neural network-based predictive controller is compared to a conventional controller during a one-week semi-virtual test. Test results showed that the predictive controller can provide up to 40% energy savings in comparison with a conventional controller.
