As part of its contribution to IEA Annex 60, the Institute for Energy Efficient Buildings and Indoor Climate of RWTH Aachen University will make its Modelica HouseModels library available. The scope of this paper is to provide information about the library. The first part presents the library and its functionality. In the second part a room model is evaluated by using Case 600 from the test suite provided by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) in the standard 140.
the authors introduce a multifunctional control research test bench and its data management and interface system. They implemented a building monitoring, control, and interface system (MCIS) used for evaluation of complex building energy systems, for optimization of such energy systems and for carrying out control research experiments. In this paper they explain the MCIS' architecture and functionality, they present its research potential and three different control research use cases for building energy systems and heating, ventilation, and air conditioning (HVAC) systems; model-assisted control parameter fine tuning, model-based predictive control, and demonstration of adaptive control algorithms. The authors outline prerequisites for implementation, demonstration, and evaluation of new developed control algorithms and strategies. These prerequisites are fulfilled via system expansions providing a flexible demonstration bench.
This paper presents an application of the hardware-inthe-loop-method to a building energy and control system. We focus on investigating the interaction of a real circulating pump with the hydronic network of a virtual building energy and control system. For real-time simulation the building envelope is modelled using the Modelica-based library AixLib. With the presented setup model-based designed control algorithms are tested directly on real hardware. The performance of the presented and implemented setup is evaluated by comparing simulated results with experimental hardware-in-the-loopsimulation data. The main focus of this work is to evaluate the application of the method towards bridging the gap between model-based design and commissioning of energy efficient control for heating ventilation and air conditioning (HVAC) components.Hardware-in-the-loop-(HIL-) simulation is a method to bridge the gap between simulation and real hardware
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
