This shows as slightly better fan static pressure
performance for the same airflow.
Figure 2 shows examples of ratios of static pressure
loss per air path compared to energy recovery effectiveness for sensible-only crossflow plate exchangers and total (sensible and latent) recovery wheels.
Variable Experimental Ranges E Ranges Static pressure
[+ or -]0.
Mass averaged total and static pressures
obtained from the probe traverses are higher for configuration with pressure surface squealer
Both of the airflow chambers had assist blowers whose speed could be modified to independently adjust the static pressures
at the primary inlet and discharge to the FPTU to the desired values for each test.
Table 1: Static pressures
for 34 split air conditioners with furnaces.
The pressure-airflow characteristic function for each path relates the airflow rate through each path to differential static pressures
at two connected nodes.
Typically, an operator theorized a problem might be system effect, but looking at the fan curve and the static pressures
, rpm, etc.
2012), the models developed from the prior experimental work allowed a modeler to use the sets of equations to simulate the hourly performance of a particular FPTU in a building if the static pressures
inside the duct system were known.
One must be aware that higher operating static pressures
increases the acoustic signature of the ACBs.
