1. Fluid mechanics, especially in the context of air<\/h3>\n

Warm air is lighter than cold air. So in a closed and unventilated room or space, warm air will tend to rise to the ceiling and stay at a high level, while the cold air will remain at floor level.<\/p>\n

In high spaces (mezzanine levels, offices, large industrial spaces, etc.), the temperature gradient<\/strong> (difference) between floor and ceiling can be very significant (up to 10\u00b0C), and is proportional to the ceiling height.<\/p>\n

The general assumption is that above the height of 4 metres<\/strong> in a closed and unventilated room, the spontaneous rising of hot air to the ceiling or roof results in an increase in air temperature of around 1.5\u00b0C per metre<\/strong>.<\/p>\n

The result of this physical effect is thermal stratification of the ambient air<\/strong>, which is to say that the air is divided into layers of different temperatures; lower at floor level and rising towards ceiling or roof level.<\/p>\n

This spontaneous stratification of the ambient air in closed and unventilated spaces, whether domestic (mezzanine floor<\/em>) or commercial (large industrial spaces, etc.<\/em>), will have the following outcomes:<\/p>\n

    \n
  • A significant energy loss<\/strong> between floor level (at which the room is heated and its occupants live, work and move around) and ceiling or roof level. This loss will effectively result in the space being overheated<\/strong> in an attempt to maintain comfortable conditions at floor level.<\/li>\n
  • A waste of money<\/strong> as a result of heating the ceiling or roof unnecessarily, and overheating the space as a whole.<\/li>\n
  • Ecological mismanagement<\/strong>.\/li><\/li>\n<\/ul>\n

    To counter this level of inconvenience and waste as a result of fluid mechanics, the construction industry has developed mechanical room air destratification<\/strong> techniques that continuously circulate<\/strong> the air, bringing hot air downwards and sending cold air upwards.<\/p>\n

    The new environnemental standards RE2020 aim to reduce the impact of new buildings on the climate and lower their energy consumption.
    \nExhale fans are an economical and proven way to help achieve these ambitious climate goals.
    \nWith Exhale bladeless ceiling fans, you will improve winter comfort and summer comfort while reducing energy costs.<\/p>\n
