The system has an external air collector (3), air feed (5) and used air (9) channels, heat exchanger pipes (6), a collector (8), a deflector (11) and a flap(2). The cold channel is enclosed on five sides by hot channels, which are connected together, in order to intensify the heat exchange effect. Ribbed heat transfer pipes (18) and a diagonal fan (15) are used to prevent fire and achieve a better air condition. |
