Abstract

The air conditioning apparatus, with a refrigerating fluid which is not harmful to at least the ozone layer, includes at least a first safety zone (5) wherein at least part of said electrical and/or electronic members of the apparatus are arranged; the safety zone has selected dimensions for preventing the formation of either minimum or maximum concentration of said coolant within said flammable limits; and at least a first chamber (6) comprising said electrical and/or electronic members adapted to operate the apparatus; the chamber is crossed by an air flow initially produced by the ventilator (4) for removing any minimum or maximum concentration of the coolant falling within said flammable limits, from the chamber. <IMAGE>
