The beam has nozzles for discharging fresh air flow supply outside an air supply chamber, where the fresh air flow discharges an air flow circulation outside a room by a heat exchanger (10). The heat exchanger is used for cooling and heating the air flow circulation. The heat exchanger has different heat exchanger modules connected to each other to form a heat exchanger structure and a beam structure of desired length. The modules constitute a tube module (14a1), intermediate modules (14a2, 14a3) and a terminal module (14a4). |
