Improving plant-level heat pump performance through process modifications

However, their performance at plant-level can be affected by other changes in the plant. In this work, process changes that can improve the heat pump’s performance have been explored with Process Change Analysis (PCA) and the newly introduced split exergy grand composite curve.

This approach shows the impact of the process changes on the heat pump work requirements by studying the position of the heat pump in relation to the pinch point of the background process. Its application is demonstrated in two case studies. In the first it allowed to identify technologies that enhance heat pump performance and while reducing overall heating requirements.
