Note(s)

  1. In this sub-class, the following terms are used with the meanings indicated:
    1. "Air-conditioning" means the supply of air to rooms or spaces by means which provide for the treatment of the air in at least two of the following ways:
      1. heating,
      2. cooling,
      3. any other kind of treatment, e.g. humidification.
    2. "Ventilation" means the supply of air to, or its extraction from, rooms or spaces, and systems for circulating air within rooms or spaces, but does not cover the mere heating of rooms or spaces by the supply of heated air. The supply or circulation systems may include means for cooling the air or for treating the air in any other way than cooling or heating.
