Most regression models use outdoor dry-bulb temperature and sometimes the
dew-point temperature as the most important regressors.
In case of
dew-point temperature as shown in Figure 9, the average was at 4.19[degrees]C, standard deviation was at 12.6[degrees]C, and minimum and maximum were at -28.8[degrees]C and 26.9[degrees]C, respectively.
(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.
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.
After minutes or hours, the glass cools to below the
dew-point temperature and moisture begins to form.
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. All of the thermodynamic properties can be calculated in American traditional and metric units.
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].
In humid climates, the conventional paradigm is to determine the supply air temperature from the cooling coils that will result in the desired
dew-point temperature in the space, and then determine the chilled water supply temperature that can deliver that temperature, based on the approach temperatures achievable with conventional equipment.
