Summary

In this work, a model to analyse a CO2 water/water heat pump for the generation of hot water is described. Once the heat pump has been presented, the models employed to characterise the different components of the system will be introduced paying special attention to the heat exchangers modelling. Its originality resides in that the model is a cell-by-cell method which relies in the iterative calculation of the heat transfer area of each cell. The model is validated with experimental data. These models are included in several TRNSYS components which allow dynamically simulating the heat pump and obtaining its seasonal performance. After presenting these results, some conclusions are finally drawn.
