Apparatus for the dehumidification of a gas flow, with an outer box and an inlet port for the damp air and an outlet port for the dehumidified air, a first pre-cooling heat exchanger, and a second heat exchanger downstream of the first exchanger and also passed by a refrigerating fluid, a dampness collection chamber arranged downstream of the second exchanger; it is provided: a second chamber downstream of the collection chamber and connected to the outside of box by means of an emission mouth; a third chamber not communicating to said second chamber but connected, on one side, to the conduits of the first exchanger, and on the other side connected to the outside of the box by a respective inlet mouth. It is defined a return path from the second to the first exchanger, comprising a first leg which passes through the collection chamber, a second leg which passes through the second chamber and the respective emission mouth, and a third leg which passes through the third chamber; preferably the conduits fed by the gas flow coming from the third chamber are in a counter-flow way in relation with the gas inlet conduits arranged in the first exchanger. |
