Description
Technical field
The present invention relates to air-conditioning equipment field, in particular to a kind of perforation air-ducting ring, a kind of air-conditioner outdoor unit and
Plant air-conditioner.
Background technology
At present, adopting top air-out major diameter axial flow blower structure VRF air conditioning system more, minimize peace with outer machine
The development of platform, the high rotating speed of axial flow blower, ever-larger diameterses development trend are obvious.Fan noise is mainly by rotational noise and vortex
Noise forms, and wherein rotational noise, based on the discrete noise of low frequency, is the principal element of impact blower fan tonequality.With rotating speed
Increase, the rotational noise based on low-frequency component becomes apparent from compared to eddy current crack speedup, this low frequency " drone " abnormal sound
Also highlight becomes apparent from.With this paradoxically, with the raising of room rate, building more crypto set, the installation leaving outer machine for is empty
Between and insulating space also less, this sound is easier to cause the dislike of periphery user and complaint.
In the related, for axial flow blower low-frequency noise aspect mostly from change blade quantity, blade pitgh, leaf
The aspects such as plate shape are started with, and such as patent CN201520944895.4 adopts the leafy axial-flow leaf of Unequal distance, and this mode is compared
In equidistant axial-flow leaf, single BPF (blade pass frequency, blade passing frequency) can be become multiple BPF
Noise.This mode is equivalent to the broadband noise single noise of replacement, although tonequality feels there is a little improvement, cannot reduce it
Amplitude.
