<p>A layer of permeable material (3) is placed between a ventilator (2) and heat exchanger (5), near the ventilator. The rotation of the current of air coming from the ventilator and passing through the permeable material is neutralised. In the same gap, but near the exchanger (5) is an empty space (4), where different air speeds are equalised by side movements of the air flow. The antirotation bed can be made of a large number of parallel channels or it can be an air filter, while the space can be wholly or partially filled with granules or twisted or spiral articles that allow sde movement of the air flow.</p> |
