A combination of thecross-flow duct 100 and thecentrifugal duct 300 forms the cross-flow centrifugal duct configuration of the split-floor-type air conditioner. A portion of the body corresponding thecross-flow duct 100 has a first airinlet frame component 400 used to supply wind to thecross-flow turbine 120 located inside thecross-flow duct 100, and afirst air outlet 500 used to outlet wind passing through thecross-flow turbine 120, the body has a second airinlet frame component 600 which can supply wind to theturbine 310 located inside thecentrifugal duct 300, the body further has asecond air outlet 700 which can outlet wind passing through thecentrifugal volute 320. - The
cross-flow turbine 120 and theturbine 310 can be driven to rotate simultaneously by thefirst motor 110, meanwhile two different kinds of gas flow modes are existed in the body with the action of thecross-flow volute 130 and thecentrifugal volute 320. Air flow coming from the first airinlet frame component 400 flows in along a direction perpendicular to an axis of thecross-flow turbine 120, that is, the air flow coming from the first airinlet frame component 400 flows in along a radial direction of impeller of thecross-flow turbine 120, passes through an inside of the impeller, and is discharged through another end along the radial direction, the air flow can flow crossly or flow transversely, and be discharged through thefirst air outlet 500 finally, a route of the air flow is a straight line.
