Relative Humidity of air (RH)
Air Relative Humidity (RH) is the amount of vapour in the air relative to the amount that it would hold if saturated, that is 100%RH at a given temperature.
Relative humidity and temperatureThe amount of water vapour the air can hold when saturated increases with its temperature.
Heated airIf the air is heated up while the real amount of water remains constant, the relative humidity content (%RH) decreases.
Cooled airSimilarly, if air is cooled down, the amount of water vapour that it can hold decreases and the relative humidity content (%RH) increases.
Condensation and indoor air quality
Cold surface or thermal bridgeExcess of water in saturated air causes condensation. Thus moisture vapour is deposited on the first cold surface, such as windows, the air contacts.
Relative humidity measurementWithin the monitoring of indoor air quality, a stand-alone logger allows to monitor CO2 as well as comfort parameters -relative humidity and temperature- in time.
