The function of the air conditioning systems is to ensure proper air circulation and maintaining the optimum temperature for enabling the physical and mental health of man in a comfortable indoor climate. 

The distribution takes place via root canal treatment and has to cover the insulation to prevent miss to cold and less energy consumption and a street light.

In addition to minimize of the miss of the energy consumption and a street light, it has to avoid condensation on the air ducts and reducing the noise during the ventilation  

Condensation on the channels must be absolutely avoided because, in addition to compromising the efficiency of the system, it creates an environment conducive to proliferation of mold and bacteria and damage the countertops with the constant dripping of water.

A good designer have the scope of define the minimum thickness of the insulation for an environment to avoiding condensation and reduce the energy loss, taking into account the technical performance of the insulation according to the terms of use.
