Kind Code:
A1
Abstract:
Provided is a package-type compressor that is capable of improving cooling performance for cooling a body unit and a control panel. This package-type compressor is provided with: a cooling fan 30 that induces a flow of cooling air taken in at cooling air inlets 8A and 8B and discharged at cooling air outlets 9 and that is housed in a fan duct 27; a machine chamber 10 through which the cooling air taken in at the cooling air inlet 8A flows along the body unit 11; and a cooling duct 35 through which the cooling air taken in at the cooling air inlet 8B flows along the control panel 34. The center position O1 of the suction port 28 of the fan duct 27 is set to be offset, so as to be closer to the cooling air inlet 8B and farther from the cooling air inlet 8A, with respect to the center position O2 of the drive shaft 16 of the motor 14 of the body unit 11.
