Adaptive Control and Fault Detection of HVAC Equipment in Commercial Buildings

February 27, 2002 - 12:00pm
Bldg. 90
Seminar Host/Point of Contact: 

This presentation reviews a new pattern recognition adaptive controller (PRAC) for heating, ventilating and air-conditioning (HVAC) equipment and recent results on the development of fault detection systems for HVAC equipment. PRAC simplifies the use of adaptive controls and reduces the amount of time required to commission HVAC systems. PRAC eliminates the need to adjust HVAC systems manually between winter and summer seasons. In addition, PRAC controllers improve the efficiency of HVAC systems, which minimizes energy use and improves indoor air quality. As a result, PRAC can lead to lower costs associated with heating and cooling functions as well as maintenance of systems. This presentation will include commercial facility field test results. Fault detection is an automated method for detecting abnormal performance in HVAC and building systems. This presentation reviews field test results for both whole building and component level fault detection systems. Using these fault detection systems will improve comfort and reduce operation and maintenance costs in buildings.
