FAULT DETECTION IN HVAC-SYSTEMS USING BUILDING INFORMATION MODELS AND HEAT FLOW MODELS

摘要

heat flow model (HFM: Heat Flow Model) graph modeling techniques to provide a system and method for technology . Examples are building information model : the HVAC system automatically converts the formal description of a graph from the HFM and (BIM Building Information Model), and compile the graph to the executable FDD system. During the engineering phase , which are not found in the BIM parameters , conditions , and the user interface is used to enter the switch . During the run-time phase , real-time data from the HVAC control system is input to the fault detection and the generated FDD systems for diagnosis (HFM graph ).
