VARIABLE AIR VOLUME MODELING FOR AN HVAC SYSTEM

A method for analytics in heating, ventilation, and air conditioning (HVAC) is described. Operation of an air-handling unit in an HVAC system is measured, including fan speed, pressure, power input, and flow. The measurements are transmitted to a processor, which analyzes the operation of the air-ha...

Zusammenfassung:A method for analytics in heating, ventilation, and air conditioning (HVAC) is described. Operation of an air-handling unit in an HVAC system is measured, including fan speed, pressure, power input, and flow. The measurements are transmitted to a processor, which analyzes the operation of the air-handling unit. The analysis includes optimizing a heuristic model of air handling in the HVAC system based on a combination of two or more of the fan speed, pressure, power input, or flow, and determining, based on the optimized heuristic model, a diversity from a fan flow set point and a fan designed maximum flow. A display presents an indication of a mismatch of a fan with a space based on the diversity.
