Abstract
The utility model relates to a ventilator structure with function of reducing noise from air flow from indoor cabinet of air conditioner. The utility model consists of a centrifuge volute with a ventilation outlet, a centrifuge fan, a driving electric machine and a driving system. The utility model designs the volute at proper position and adopts the air current pressure formed by the centrifuge fan reasonably, thereby remarkably reducing the noise caused by ventilation air collecting opening at the back of fan on the condition of no reduction of recirculation air and heat exchanging efficiency and saving driving power of the fan.
Description
The utility model relates to a kind of fan structure that reduces cabinet-type air conditioner draft noise in the air conditioner chamber, particularly cabinet-type air conditioner ventilation outlet in the air conditioner chamber is arranged on anticentripetal spiral casing along the fan direction of rotation apart from the snail tongue air-exchanging structure in 0 to 180 ° of scope.
Fig. 1 is the common installation position of cabinet-type air conditioner ventilation gas collection mouth in the existing air conditioner chamber, and the obstruction of runner has been caused in the downstream that the gas collection mouth of taking a breath is placed in centrifugal fan, forms strong separated flow.This structure has increased the resistance of air-flow, in order to guarantee the air circulation of air, must increase the rotating speed and the driving power of fan, thereby increase air-conditioner noise in the running.
And the high pressure draught in the segment distance that begins from the snail tongue in the spiral case of centrifugal fan is difficult to discharge outlet through turning to of big half-turn.So it is suitable that this part high pressure gas is used to take a breath.
The purpose of this utility model is achieved in that
Fig. 2 is the utility model scheme: the outlet (1) of will taking a breath is arranged in the scope of (2) 0 to 180 ° along the fan direction of rotation apart from the snail tongue of anticentripetal spiral casings (3).
This method can make cabinet-type air conditioner draft noise attenuating 2-4 decibel in the air conditioner chamber.
Claims (2)
1, a kind of air-exchanging structure that reduces cabinet-type air conditioner draft noise in the air conditioner chamber is characterized in that: be made up of an anticentripetal spiral casing that has a ventilation outlet, centrifugal fan, drive motors and transmission system.
2, a kind of air-exchanging structure that reduces cabinet-type air conditioner draft noise in the air conditioner chamber according to claim 1 is characterized in that: the outlet of will taking a breath is arranged in the scope of 0 to 180 ° along the fan direction of rotation apart from the snail tongue of anticentripetal spiral casing.
