After numerous tests, it became clear that the measurement procedure was critical in order to obtain accurate and repeatable wet-bulb temperature
relative humidity, specific volume, dry-bulb temperature, and wet-bulb temperature
Options include display of water quality--pH and dissolved solids--as well as wet-bulb temperature
In LCAM 1E, the dew-point temperature at the peak dry-bulb temperature and mean coincident wet-bulb temperature
was assumed to prevail through the day unless the dry-bulb temperature fell below the dew point.
25 in summer, depending on the ambient wet-bulb temperature
wb,i] = wet-bulb temperature
of the air entering the cooling coil in zone i ([degrees]C); [T.
Thus, scaling EWMA forecasts based on external wet-bulb temperature
forecast extremes is generally not recommended, even with perfect prediction.
The unsorted lumber (L + M + H) was dried with a time-basis schedule consisting of an initial 6 hours warm-up ramp, seven successive steps in which dry-bulb and wet-bulb gradually increased every 24 hours, and a final step at a constant 78[degrees]C dry-bulb and 65[degrees]C wet-bulb temperature
that ended when the average lumber MC was approximately 15 percent.
This results in a fictitious inlet wet-bulb temperature
that is used to re-evaluate capacity and EIR with Equations 1 and 2.
We therefore determined that in order to minimize the impact of secondary climate variables, we would only use NARCCAP data pertaining to dry-bulb temperature, wet-bulb temperature
, atmospheric pressure and corresponding atmospheric variables that could be calculated directly from these primary variables (e.
When air flows over a surface wetted with water, evaporation from the film of water will lower the temperature of the water-air interface toward the wet-bulb temperature
of the air.
Water-side free cooling, which uses cooling tower water to cool the load without operating the compressor of the chillers when the ambient wet-bulb temperature
is sufficiently low, does not have these limitations but does require special considerations to avoid the tower freezing during winter operation.
