Technical term :

Speciality :

A/C > States

Absolute humidity :


Absolute humidity humidity

Fr : humidité (f)
All : Feuchtigkeit (f)
An : humidity
It :
indicates the actual amount of steam in the air.


- A/C > States

Dictionary :

Anglais : absolute humidity
Franais : humidité absolue (f)
Allemand : absolute Feuchte (f)
Italien :


Vapour pressure :


If dry air strokes a liquid it takes up humidity humidity

Fr : humidité (f)
All : Feuchtigkeit (f)
An : humidity
It :
in the form of vapour. The vapour pressure depends on the temperature of the water at the time.


- A/C > States

Dictionary :

Anglais : vapour pressure
Franais : pression de la vapeur (f)
Allemand : Dampfdruck (m)
Italien :


Wet bulb temperature :


Using the humid thermometer according to Assman, the wet bulb temperature can be measured. To do this, the mercury in the thermometer is wrapped in webbing, soaked in distilled water and moved around in the air. The evaporation of the water takes heat out of the air and out of the water. The thermometer cools down until it reaches a state state

Fr : état (m)
All : Aggregatszustand (m)
An : state
It :
of equilibrium. The resulting temperature is the wet bulb temperature. This has a practical application when water is cooled in a cooling cooling

Fr : refroidissement (m)
All : Kühlung (f)
An : cooling
It :
tower.


- A/C > States

Dictionary :

Anglais : Wet bulb temperature
Franais : température de bulbe humide (f)
Allemand : Feuchtkugeltemperatur (f)
Italien :


Psychrometric difference :


Dry and wet bulb temperatures as well as the dew point temperature are the same in the case of saturated saturated

Fr : saturé
All : gesättigt
An : saturated
It :
air. The difference between dry and wet bulb temperature is called the psychrometric difference.


- A/C > States

Dictionary :

Anglais : psychrometric difference
Franais : différence psychrométrique (f)
Allemand : psychrometrische Differenz (f)
Italien :


Relative humidity :


As it is not usual to measure absolute humidity humidity

Fr : humidité (f)
All : Feuchtigkeit (f)
An : humidity
It :
in the air, air conditioning engineering expresses steam content in relative humidity. This amount can be by measured in a hygrometer, for example. Relative humidity humidity

Fr : humidité (f)
All : Feuchtigkeit (f)
An : humidity
It :
is the ratio of the partial pressure to thesaturated pressure of the steam at the same temperature (at dew point).

Dictionary :

Anglais : relative humidity
Franais : humidité relative (f)
Allemand : relative Feuchte (f)
