Air in the organic setting consists of a specific quantity of moisture as is needed for plants and animals to exist. In automobile storage the aim is to management the quantity to a manageable degree. The ratio of the quantity of moisture in the air in contrast to the highest that the air can hold at a offered temperature is named Relative Humidity or RH. It is expressed as a percentage. For any offered quantity of moisture, the increased the air temperature the decrease the RH%. Equally the decrease the air temperature is the increased the RH%. In winter the air seems to be noticeably wetter than in summer season.
It is the cooling of air that brings about the difficulties. As air cools it can hold much less moisture till a stage is reached exactly where the air is entirely saturated (one hundred% RH) – recognized as the dew stage. If the automobile, equipment, or something else in this setting, is at a temperature under the dew stage of this air, moisture is then offered up by the air as condensation. This manifests itself as moist automobile surfaces, rust on equipment, damp paperwork and so on. Due to the fact the moisture condensed out from the air is pure distilled water it is also the excellent setting to inspire the development of moulds and fungal spores, one thing you surely really do not want to have to fear about with lengthy phrase automobile storage.
The remedy to the dilemma is to lessen the dew stage to a degree under the temperature of any element of the garage and its contents AND to maintain the RH% inside managed ranges.
