4) The result of this strategy is a supply airstream with a supply dry-bulb temperature
significantly higher than the supply dew-point temperature and a latent cooling capacity greater than the sensible cooling capacity.
The relationship between the wet-bulb temperature, the dry-bulb temperature
, and the dewpoint temperature is nonlinear.
The methodology for calculating the return periods for extreme wet-bulb temperature, both minimum and maximum, was identical to that used for dry-bulb temperature
, representing return periods of 5, 10, 20, and 50 years.
Meteorological data of dry-bulb temperature
, wet-bulb temperature, relative humidity, and temperature humidity index (THI) were significantly different by time (p < 0.
It's called that because it can be measured with a thermometer wrapped in a wet cloth, distinguishing it from the commonly reported dry-bulb temperature
, measured in open air.
variable, in this case, averaged outdoor air dry-bulb temperature
, [degrees]F, [[beta].
It was assumed that the gas was saturated for the first part of the cycle while the evaporation rate was high and that after a selected dry-bulb temperature
was reached, the air was no longer saturated.
The lowest temperature that can be achieved by air-blast cooling is related to the dry-bulb temperature
and is therefore higher than the temperatures that can be achieved by a cooling tower.
a] is the air dry-bulb temperature
of the space, [[?
(expressed in [degrees]C) and relative humidity (expressed in %) was collected at 1-h intervals from the weather station in the city, near the abattoir (22[degrees]01'03"S, 47[degrees]53'27"W; 856 m above sea level), from January to December of 2006.
relative humidity, specific volume, dry-bulb temperature
, and wet-bulb temperature.
The floating head pressure controller controls head pressure to a constant degree of approach to the dry-bulb temperature
for air-cooled condensers and to the wet-bulb temperature for evaporative condensers.
