External environment humidity and outside atmosphere pressure value etc., to improve the Outdoor Air Parameters precision of acquisition.
Current outdoor environment is calculated according to the outdoor environment temperature of acquisition, outdoor environment humidity and outside atmosphere pressure value
Dew-point temperature, for example, at 23 degree, under the humidity environment of RH45%, corresponding algorithm of dew point are as follows: first by tabling look-up,
23 degree of corresponding saturation vapour pressures, i.e. 21.07 millimetress of mercury are searched on the corresponding saturation vapour pressure of temperature, then use 21.07*
45% (humidity needed)=9.4815, then find 9.4815 corresponding saturation vapour pressures by tabling look-up, when not fitting like a glove
Value, just lower change point takes a temperature value in proportion on it, which is dew-point temperature, therefore, at 23 degree, RH45%'s
Under humidity environment, corresponding dew-point temperature is 10.5 degree.Dew-point temperature refers to that air is all immovable in moisture content and air pressure
Under the conditions of, it is cooled to temperature when saturation.When steam has reached saturation in air, temperature is identical as dew-point temperature；Work as steam
When being not up to saturated, temperature is centainly higher than dew-point temperature.So the difference of dew point and temperature can indicate the steam in air away from
Degree from saturation.Temperature drops to the necessary condition that dew point or less is condensation vapor.
