Analysis of HVAC System and Building Performance Utilizing IR, Physical Measurements and CFD Modeling

From Flir Systems Incorporated
 

 
Reported problems with recently constructed buildings exposed to severe climatic conditions led to a legal case regarding the performance of the heating systems and the buildings. The buildings were examined using visual methods, infrared imaging, blower door, and flow hood measurements, and modeled using CFD (computational fluid dynamics) software for both air flow and heat transfer. Information from the measurements provided the data that allowed development of a comprehensive CFD model of the air and heat flows in the building, which in turn, gave a visual illustration of the air paths in the structure. These illustrative exhibits aided the writers in developing a method of presentation for the legal proceedings, as well as confirming the owner reported complaints of stratification in the units. The findings will be reviewed and the measurements and simulations compared in this paper.
