Abstract
The utility model provides a low noise central air conditioning, including the air conditioner shell with set up in fan on the air conditioner shell, still including the current stabilizer who is used for the noise reduction, current stabilizer set up in the fan with in the wind channel of formation between the air conditioner shell. The utility model provides a low noise central air conditioning through forming current stabilizer to the intermediate bottom turn -ups, changes air distribution's runner to solution fan that can be fine blow the fin sound, reduce fan coil's noise, simple structure, convenient to use.
Description
Technical field
The utility model belongs to air-conditioning equipment field, particularly relates to a kind of low noise central air-conditioning.
Background technology
The multiple advantage that fan coil possesses, fan coil is made to become the desirable end of central air-conditioning, in addition along with the development of fan coil technology, its field used also expands gradually, is now mainly used in some relatively large places such as office, hospital, scientific research institution.
For high-static pressure fan coil pipe unit, its noise level becomes key factor, and GB has clear and definite requirement to this.And in its noise is formed, aerodynamic noise accounts for mainly.For high-static pressure fan coil pipe, under fan coil units is in high-speed state, directly blow to heat exchanger fin from the high velocity air of centrifugal blower blowout, because wind speed is higher, fin thickness is general all thinner, high velocity air blows on fin, fin produces vibration, especially for the fan coil units of high static pressure, this phenomenon is more obvious, produce and larger blow fin sound, mouthpiece whistle is even had time serious, although noise level entirety is not high, but for domestic consumer, this obvious different sound allows people be difficult to accept, thus more think that unit total noise of centrifuge is higher.
Utility model content
Therefore, the utility model provides a kind of low noise central air-conditioning that can reduce noise.
A kind of low noise central air-conditioning, comprises air conditioner housing and is arranged at the blower fan in described air conditioner housing, also comprise the constant-current stabilizer for reducing noise, and described constant-current stabilizer is arranged in the air channel that formed between described blower fan and described air conditioner housing.
Described blower fan is fixedly connected with by central dividing plate with described air conditioner housing, and described constant-current stabilizer is arranged on described central dividing plate.
Described constant-current stabilizer is arranged at edge on described central dividing plate.
Described constant-current stabilizer is formed towards described air conditioner housing flange by described central dividing plate.
Described constant-current stabilizer comprises the horizontal segment, wind-guiding section and the flow-disturbing section that connect successively, and described horizontal segment is perpendicular to described central dividing plate, and described wind-guiding section and described horizontal segment have the first angle, and described upset section and described wind-guiding section have the second angle.
The scope of described horizontal section length is 8 to 10mm, and described horizontal segment is arranged in described air conditioner housing.
The scope of described first angle is 160 ° to 170 °, and described wind-guiding section is edge bending under described central dividing plate.
Described wind-guiding segment length scope is 25 to 30mm.
The scope of described second angle is 135 ° to 150 °, described flow-disturbing section and the V-shaped structure of described wind-guiding section.
The length range of described flow-disturbing section is 8 to 10mm.
The low noise central air-conditioning that the utility model provides, by central dividing plate flange is formed constant-current stabilizer, changes the runner of air current composition, thus can well solve blower fan blow fin sound, reduce the noise of fan coil, structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the low noise central air-conditioning that the utility model provides;
Fig. 2 is the structural representation of the constant-current stabilizer of the low noise central air-conditioning that the utility model provides;
Detailed description of the invention
Also the utility model is described in detail by reference to the accompanying drawings below by specific embodiment.
Low noise central air-conditioning as depicted in figs. 1 and 2, the blower fan 1 comprising air conditioner housing 2 and be arranged in described air conditioner housing, also comprise the constant-current stabilizer 3 for reducing noise, described constant-current stabilizer 3 is arranged in the air channel that formed between described blower fan 1 and described air conditioner housing 2.
Described blower fan 1 is fixedly connected with by central dividing plate with described air conditioner housing 2, and described constant-current stabilizer 3 is arranged on described central dividing plate.
Described constant-current stabilizer 3 is arranged at edge on described central dividing plate.
Described constant-current stabilizer 3 is formed towards described air conditioner housing flange by described central dividing plate.
Described constant-current stabilizer 3 comprises the horizontal segment 31, wind-guiding section 32 and the flow-disturbing section 33 that connect successively, described horizontal segment 31 is perpendicular to described central dividing plate, described wind-guiding section 32 has the first angle with described horizontal segment 31, and described upset section 33 has the second angle with described wind-guiding section 32.
The scope of described horizontal segment 31 length L1 is 8 to 10mm, and described horizontal segment 31 is arranged in described air conditioner housing 2.
The scope of described first angle theta 1 is 160 ° to 170 °, and described wind-guiding section 32 is edge bending under described central dividing plate.
Described wind-guiding section 32 length L2 scope is 25 to 30mm.
The scope of described second angle theta 2 is 135 ° to 150 °, described flow-disturbing section 33 and the V-shaped structure of described wind-guiding section 32.
The length L3 scope of described flow-disturbing section 33 is 8 to 10mm.
By the structure of described constant-current stabilizer, due to the effect of centrifugal blower, when air-flow blows out from centrifugal blower, there is break-in in the air-flow that top wind speed is large, and then blows to heat exchanger herein, and blower fan blows fin sound and effectively reduced, total noise of centrifuge is also reduced simultaneously, through repeatedly actual machine test, the fan coil units of high static pressure, under equal air quantity level, can realize noise and can fall 1 ~ 2 decibel on a year-on-year basis.
Only preferred embodiment of the present utility model by the above; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
