CONDENSING HOT AIR GENERATOR

摘要

The hot air generator (10) comprises a primary heat exchanger (14) and a secondary heat exchanger or condenser (15). The primary heat exchanger (14) and the secondary heat exchanger (15) are placed in parallel to each other with respect to the direction of flow of the air to be heated. A damper (18) is arranged at the inlet of a duct leading the flow of air to be heated to the secondary heat exchanger (15), in order to control the rate of air flow towards said secondary heat exchanger (15).
