It includes the following recommendations: (1) measure all possible interior airflow directions and create a multi-zone model, (2) measure all bulk air handling unit (AHU) airflows, (3) identify all flow paths for which the simulation has incorrectly predicted flow direction, (4) identify the lowest unmeasured branch levels of HVAC flows associated with the incorrect airflow directions, (5) measure the associated HVAC airflows in those areas, (6) revise the model based on these measurements (this becomes the new "best guess" model), (7) evaluate model quality and repeat starting at step (2) if unsatisfactory, and (8) perform a regression analysis to estimate the difficult or impossible to measure factors (e.
Total supply, return, and outdoor airflows of AHUs were measured by fan inlet or duct-mounted flow stations using thermal dispersion sensor probes ([+ or -]2% reading) if feasible.
The blow and vacuum airflows are provided by the central blow, vacuum and filtration unit.
This will result in reheating of the room, hotter systems, unhealthy airflows, and a substantial reduction in the efficiency of the cooling system.
Generally, a smoke generator, light source, and digital camera are used to visualize the airflows qualitatively around the model on the turntable.
