Abstract

Air exchanger and conditioning device comprising a device for introducing fresh air and a device for extracting air contained in a given area, and a motor connected to both of said devices for driving the same at the same speed.

Claims

1. An air exchanger comprising, a driven exhaust blower for exhausting a given volume of exhaust air from a given space, a driven intake blower for introducing a volume of intake air into said space equal to said given volume, drive means common to said exhaust blower and said intake blower driving both blowers at equal speeds simultaneously, means defining an exhaust duct for exhausting said exhaust air, means defining an intake duct coaxial with the exhaust duct for introducing intake air in a volume equal to the volume of air exhausted, said intake duct comprising an annular portion disposed circumferentially of the exhaust duct, and said exhaust duct and said intake duct having an equal volume, whereby the air pressure is maintained constant in said space.

2. An air exchanger according to claim 1, in which said exhaust blower comprises a centrifugal blower and in which said intake blower comprises an axial blower.

3. An air exchanger according to claim 2, in which said means defining said intake duct comprises stationary, hollow vanes disposed circumferentially spaced around said centrifugal blower, and said stationary vanes being disposed in position for airflow from said axial blower to pass therethrough and exhaust air discharged from said centrifugal blower to flow therebetween, anD said annular portion of said intake duct being disposed downstream of said hollow vanes and in communication therewith.

4. An air exchanger according to claim 3, in which said axial blower is disposed upstream of said hollow vanes.
