Abstract
The utility model discloses an air return channel of an air conditioner. According to the air return channel, a plurality of noise reduction measures are taken, for instance, the flow direction of air is changed and sound absorbing material adheres to the inner surface are adopted, and therefore the noise of the air return channel of the air conditioner can be effectively reduced. The air return channel of the air conditioner comprises an upper sound absorbing chamber connected with an air return opening of an air conditioner unit and a lower sound absorbing chamber connected with the upper sound absorbing chamber, the lower sound absorbing chamber comprises a lower sound absorbing frame and a multihole plate located at the bottom of the lower sound absorbing frame. Four flow guide sound absorbing plates which form a certain angle with the direction perpendicular to air flow and are symmetrically arranged are installed in the lower sound absorbing chamber, and therefore on the one hand, by continuously changing the spreading direction of the noise, the noise of an air blower of the air conditioner is prevented from being directly spread into a room, and on the other hand, the sound absorbing materials on the inner wall of the lower sound absorbing chamber and the sound absorbing plates can have the sound absorbing effect. The air return channel of the air conditioner is not only suitable for noise reduction of air return channels of air conditioners in passenger rooms of rail trains but also suitable for noise reduction of air return channels of air conditioners in other places.

According to the optimal way of embodiment, insert in upper absorption chamber the upper part of described lower absorption chamber, and be provided with vibration isolation sealing gasket between described upper absorption chamber and lower absorption chamber.
In order to guide air-flow to enter smoothly the return air inlet for air-conditioner of top by air air-return duct, described lower water conservancy diversion acoustic board and upper water conservancy diversion acoustic board are all obliquely installed to circulation of air direction, can avoid air-conditioning ventilating noise directly to propagate on the one hand indoor, can guide on the other hand the air-flow flowing into from return air entrance to pass through smoothly air-return duct.
Described upper absorption chamber comprises absorption chamber framework and the upper junction plate being attached thereto respectively and lower connecting plate, and described upper absorption chamber framework is arranged on body of wall by upper junction plate and lower connecting plate.Described lower absorption chamber is suspended on body of wall by suspension assembly.
According to the optimal way of embodiment, described suspension assembly comprises and the C type mounting groove of wall connecting and support gusset for being connected with lower absorption chamber framework, described C type mounting groove by bolt assembly with support gusset and be connected; And for the transmission of further vibrating between isolation body of wall and lower absorption chamber, between described C type mounting groove and support gusset, vibration isolator is set.
In order further to absorb the partial noise in air-conditioning duct, the framework inwall of described upper absorption chamber and lower absorption chamber is all pasted with sound-absorbing material.The upper surface of described upper water conservancy diversion acoustic board and lower water conservancy diversion acoustic board is provided with sound-absorbing material.
The operation principle in the air-conditioning return air road based on said structure is, when operation of air conditioner, in the porous plate of air by lower absorption chamber bottom, disperses to suck, under stable entering in absorption chamber.Framework inwall in described lower absorption chamber is due to four angled with air-flow vertical direction and be arranged symmetrically with water conservancy diversion acoustic boards being installed, air is carried out to water conservancy diversion, can avoid air-conditioning ventilating noise directly to propagate on the one hand indoor, the air-flow that can lead back to smoothly on the other hand air port inflow passes through air-return duct smoothly.Simultaneously, described lower absorption chamber and wall connecting position have adopted vibration isolation processing, by vibration isolator and upper absorption chamber and the middle vibration isolation sealing gasket of installing of lower absorption chamber of suspension assembly, isolated the transmission of vibrating between body of wall and lower absorption chamber, strengthened sealing between the two.
In order better to increase noise reduction, on the inwall of absorption chamber up and down in air-conditioning return air road and water conservancy diversion acoustic board, all pasted sound-absorbing material, can further absorb like this noise in air-return duct.
In sum, the air-conditioning return air road utilization that the utility model provides changes air flow and at multiple noise reduction measures such as inner surface sticking sound-absorbing materials, effectively reduces the noise in region, air-conditioning return air road.Described air-conditioning return air road had both been applicable to the noise reduction of the air-return duct of track train guest room air-conditioning, was also applicable to the air-return duct noise reduction process of other occasion air-conditionings.
