Of the climate parameters, only absolute humidity was positively [[Beta] = 0.5 (EU/[m.sup.3])/(10g [H.sub.2]O/kg air)] and significantly (p = 0.01) associated with airborne endotoxin levels.
The absolute humidity at the living wall exit is 0.0019 [lb.sub.w]/[lb.sub.a] + 0.00012924 [lb.sub.w]/[ft.sup.3] x 13.392 [ft.sup.3]/[lb.sub.a] = 0.0036308 [lb.sub.w]/[lb.sub.a] (3.6308 g/kg).
For both experiments, the average of the absolute humidity was [bar.W] = 0.0075 [+ or -] 0.0004 [kg.sub.w]/[kg.sub.a] (0.0075 [+ or -] 0.0004 [lb.sub.w]/[lb.sub.a]), and the absolute humidity difference between the cavity and the surroundings was [DELTA]W = 0.015 [+ or -] 0.0008 [kg.sub.w]/[kg.sub.a] (0.015 [+ or -] 0.0008 [lb.sub.w]/[lb.sub.a]).
Water layers are more likely in high relative humidity, Thus, the relative humidity is assumed more important than the absolute humidity.
During the winter, air significantly below freezing will have very low absolute humidity levels.
The mass of condensed water vapor is calculated by taking the difference between the absolute humidity of incoming air and the outgoing air to the evaporator.
* Reducing the absolute humidity (dew-point temperature) does not always lead to an increase in voltages, but the threshold at which a reversal may occur is low--in the range of -10[degrees]C to 0[degrees]C (14[degrees]F to 32[degrees]F).
These include total sky cover, dry-bulb temperature, dew-point temperature, relative humidity, absolute humidity, pressure, and wind speed.
That is, the absolute humidity of the RO stream increases and the absolute humidity of the PO stream decreases with increasing RI stream temperature.
To avoid condensation (on the surface or inside the structure), the surface temperature and the absolute humidity must be controlled.
