dew point

n. Abbr. DP
The temperature at which air becomes saturated and produces dew.

dew point

or

dewpoint

n
(Physical Geography) the temperature at which water vapour in the air becomes saturated and water droplets begin to form

dew′ point`


n.
the temperature to which air must be cooled, at a given pressure and water-vapor content, for it to reach saturation; temperature at which dew begins to form.
[1825–35]

dew point

The temperature at which air becomes saturated with water vapor and dew forms. The dew point varies depending on how much water vapor is in the air.

dew point

The point at which air saturated with water vapor produces condensation which forms dew.

The vapor pressure of water vapor in air increases with the dew-point temperature of that air.
Looking at Table 2, it is interesting to note that AC 006, the unit that was dehumidifying, ostensibly had the lowest dew-point temperature of all six CRAC units.
3) In the former two applications, the issue is not the conflict between supply air temperature, required air turnover, and sensible load, but rather a lower limit for supply air temperature to the space that is substantially higher than the required supply air dew-point temperature to the space.
Heating the air, or lowering the dew-point temperature, creates a pressure differential (and a resulting concentration gradient); this causes moisture to diffuse from the plastic to the air.
48[degrees]F]), the dew-point temperature was measured on the R-22 system using a chilled mirror hygrometer ([+ or -] 0.
The most important thing to understand about a dehumidifier is that the efficiency and performance is directly related to the difference between the air dew-point temperature and air dry bulb temperature.
The analysis of environmental conditions such as relative humidity, air temperature, surface temperature, dew-point temperature and the difference between surface and dew point temperatures can also be viewed via the Fischer CM.
It doesn't fall, but rather forms on an exposed surface when that surface becomes colder than the dew-point temperature, which depends on the humidity.
All models are designed for a standard 7barg inlet pressure, at 35[degrees]C air inlet temperature (25[degrees]C ambient) and offer a constant 3[degrees]C dew-point temperature delivery at all times.
However, the instruments that are required to measure the dew-point temperature directly are significantly more expensive than an aspirated psychrometer.
PsychroAir uses the following input properties: barometric pressure, dry-bulb temperature, and one of the following: humidity ratio, relative humidity, wet-bulb temperature, or dew-point temperature.
The starting temperature 75[degrees]C was chosen as the dew-point temperature of flue gases of PF oil shale boiler according to investigation [1].
