  • the generated turbulent or diffuse flow causes a longer retention of the air flow within the air-throughflow layer, so that more warm or cold can be absorbed.
  • the heating or cooling power required for heating or cooling the air stream flowing through can be reduced enormously compared with the heating or cooling devices known from the prior art.
  • Another advantage of the structure according to the invention is that the heating and / or cooling device can be considerably reduced in geometric dimensions due to the improved heat or cold discharge to the air stream flowing through.
  • a particularly space-saving arrangement of the sandwich of the heating and / or cooling device is given if it is arranged directly within the ventilation layer. If the thickness of the sandwich is at least approximately matched to that of the ventilation layer, then no separate recess for the sandwich of the heating and / or cooling device needs to be provided within the cushioning layer carrying the ventilation layer, which is often made of a foam.
