Description
Technical field
The invention belongs to air-conditioning technical field, more particularly to a kind of coil pipe of air-conditioner blower.
Background technology
Central air conditioning fan coil unit, motor of the generally use between two centrifugal wind wheels, pass through the defeated of motor
Main shaft of the shaft respectively with two centrifugal wind wheels is connected, to drive two centrifugal wind wheel operatings, it is however generally that, we require to blow
Machine is low in energy consumption, and air quantity is big, and noise is low, and these three indexs are the principal elements for weighing pressure fan performance quality；It is traditional from
Noise caused by heart wind wheel spiral case mainly includes air inlet noise, spiral case noise, fan noise, and wherein fan noise includes rotation
Noise and vortex noise, vortex noise refer to that wind wheel blade when rotating, makes ambient gas produce vortex, and these vortex are due to viscous
The effect of stickiness, is divided into a series of discrete small vortex again, and vortex disturbs air with vortex breakdown, formation compress with it is dilute
Thin process, so as to produce noise.For air conditioner centrifugal wind wheel, eddy current crack accounts for major part.
