<p>The ventilation system with double air flow has a closed circuit for a medium transferring heat between two heat exchangers, one heating the air and condensing the medium and the other cooling the air and evaporating the medium. It has a cruciform structure with two hollow arms intersecting at right angles at the centre, where the shaft (3) of the shutter (4) is mounted. The first arm incorporates a double air-flow casing, the condensing heat exchanger (6) with air filters (9), and the first half (1) of a central chamber divided in half by the shutter. It also incorporates the second half (2) of the chamber, the evaporating heat exchanger (7) with air filters (9), and a second double air-flow casing.</p> |
