Apparatus for dehumidification of an air flow

摘要

Apparatus for dehumidification of a gas flow, with an outer box and inlet port for the damp air and outlet port for dehumidified air, a first pre-cooling heat exchanger, and second heat exchanger downstream of the first exchanger and passes by a refrigerating fluid, a dampness collection chamber arranged downstream of the second exchanger; providing: a second chamber downstream of the collection chamber and connected to the outside box by the emission mouth; a third chamber not communicating to the second chamber but connected, on one side, to the conduits of the first exchanger, and on the other side connected to the outside box by a respective inlet mouth. Defining a return path from the second to the first exchanger, including a first leg passes through the collection chamber, a second leg passes through the second chamber and respective emission mouth, and a third leg passes through the third chamber.

1. An apparatus for dehumidification of an air flow, comprising: an outer box provided with an inlet port for damp air inlet, and with an outlet port for outlet of de-humidified air, a first heat exchanger for pre-cooling and successively heating said air flow, and comprising two distinct and separate conduit assemblies for reciprocal heat exchange, wherein a first conduit assembly is passed by said damp air flow coming from said inlet port, and a second assembly is passed by said de-humidified air flow and is directed to said outlet port, a second heat exchanger arranged downstream of said first heat exchanger and apt of cooling said air flow and of condensing dampness therein contained, and comprising: a third conduit assembly passed by said air flow to be dried and coming from said first conduits, a fourth conduit assembly thermally associated to said third assembly, and able of being supplied with a refrigerating flow and of conveying the refrigerating flow to a refrigerant flow outlet, a collecting chamber able of intercepting and collecting the dampness of said air flow condensed inside said second heat exchanger, and arranged downstream of said second heat exchanger, wherein the apparatus for dehumidification also includes: a second chamber downstream of said collecting chamber, contiguous to said second heat exchanger and connected to the outside by a respective emission mouth, a third chamber: a) not communicating to said second chamber, b) connected to the conduits of said second assembly, c) connected to the outside of said outer box by a respective inlet mouth, able of implementing a return path from said second heat exchanger and said first heat exchanger which also comprises: a first leg which at least partially crosses said collection chamber, a second leg which passes through said second chamber and which then passes through said emission mouth, a third leg branching out from said emission mouth to said inlet mouth across a dehumidifier, a fourth leg passing through said third chamber.
