The goal of deliverable D2.4 is to build a computationally efficient 1D hot water storage tank model that can accurately predict temperature stratification under different configurations and operating conditions. This goal, in turn, provides high-precision input/output energy during the charge/discharge phase. In order to benchmark the developed model with the open-source model, we included the simulation results of the thermal energy storage tank models available in the building library [4] and compared them.
Delivering the D2.4 structure in Chapter 7 explains the following key aspects related to the adaptive mesh model of a hot water storage tank:
Chapter 1 introductory
Chapter 2: Background
Chapter 3: Adaptive Mesh Tank Model
Chapter 4: Model Validation Methods
Chapter 5: Results and Discussion
Chapter 6: Progress in progress
Chapter 7: Conclusion
The rest of this delivery is organized into six chapters. Chapter 2 explains the problems that exist in the modeling of hot water storage tanks, namely numerical diffusion and mixing coefficients. Chapter 3 describes the developed model in terms of general mechanism, mass and energy balance, etc. In Chapter 4, a set of experiments explains their operational characteristics. These tests are carried out to validate the simulation results. Then, in Chapter 5, the simulation results are compared with the experimental data, and then a detailed discussion is given. In the next chapter, we will explain the current development of this model. Finally, the accuracy and performance efficiency of the model are concluded in Chapter 7. Compiled by Chen Jiaoyun
The development of an accurate model of the heat storage tank is necessary for the initial validation of a reduced-order model of the same components for system simulation and the development of management strategies (e.g., model predictive control in the development subtask 2.2.4) to maximize stored energy and reduce heat loss.
