Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
See Fig. 1, air-supply arrangement provided by the invention, comprise intake stack 1, be arranged on the noise reduction casing 3 of described intake stack 1 one end, and the air diffuser 2 be arranged on described noise reduction casing 3 air outlet, air enters described noise reduction casing through described intake stack, enters room from the air diffuser described air outlet.Air carries out noise reduction process through noise reduction casing 1 before entering room, greatly reduces noise, avoids the noise and the pressure loss that adopt pipeline to produce directly to indoor air-supply.
Continue see Fig. 1, current equalizer 4 is also provided with in noise reduction casing 3, described current equalizer 4 is between described intake stack 1 mouth of pipe and described noise reduction casing 3 air outlet, the air entering noise reduction casing 3 through intake stack 1 enters room from air diffuser 2 after current equalizer 4, due to the water conservancy diversion current balance function of current equalizer 4, noise obtains further reduction, and the air-distribution entering room is also more even.
See Fig. 1, Fig. 3 and Fig. 5, described current equalizer 4 is platy structure, described platy structure offers multiple equal discharge orifice 41.Described current equalizer 4 is arranged between described intake stack 1 mouth of pipe and described noise reduction casing 3 air outlet, the center line of equal discharge orifice 41 and the axis being parallel of intake stack 1.The edge of current equalizer 4 is fixed on the internal face of noise reduction casing 3.Preferably, be fixed on diapire and roof.The first limit that described current equalizer 4 contacts with diapire 31 is provided with support portion 42, the another side relative with described first limit has fixed part 43, fixed part 43 is connected by screw or bolt with described noise reduction box top wall.
Preferably, described noise reduction casing 3 air outlet is positioned on diapire 31, air-out vertically downward, and described intake stack 1 is positioned on the sidewall adjacent with described diapire, and air intake direction is vertical with air-out direction.The bend muffler that air flow channel defines 90 degree is set like this, the noise from intake stack 1 can be reduced.Current equalizer 4 is inclined between described intake stack 1 mouth of pipe and described noise reduction casing 3 air outlet, current equalizer 4 and away from intake stack 1 side diapire 31 between angle theta be acute angle, as shown in Figure 2.
See the air flow schematic diagram that Fig. 2, Fig. 2 are air-supply arrangement provided by the invention.When the air that intake stack 1 enters noise reduction casing 3 flows through current equalizer 4, due to current equalizer 4, angle is set, part air-flow spreads respectively up and down along the inclined plane of current equalizer, thus play better current-sharing effect, disperseed, air-flow after current-sharing entered room from air diffuser, make air-out more even.Through experimental verification and flow field analysis, described angle theta be 30-60 when spending current-sharing effect best.
See Fig. 4, described air diffuser 2 is circular, air diffuser 2 is provided with buckle 21, noise reduction casing air outlet is provided with hole clipping, can certainly be provided with hole clipping on air diffuser 2, noise reduction casing air outlet arranges buckle, air diffuser 2 and the mutual clamping of air outlet.
See Fig. 5, described noise reduction casing 3 wall adopts orifice plate noise elimination structure, and described casing wall inside is filled with sound-absorbing material, and described sound-absorbing material can be glass fibre, sponge or foam etc.
This air-supply arrangement also comprises controller 5 and is positioned at the volume damper (not shown) of intake stack, and controller 5 sends the aperture that signal controls volume damper, thus controls the size of air quantity.
Air-supply arrangement provided by the invention, by arranging noise reduction casing, in noise reduction casing, arrange current equalizer, and the air flow channel in noise reduction casing is arranged to 90 degree, current equalizer is arranged to respective angles according to the direction of air flow channel, thus effectively reduces noise.
Present invention also offers a kind of air-conditioning equipment, this air-conditioning equipment adopts above-mentioned air-supply arrangement, thus reduces air-supply noise, improves the performance of air-conditioning.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
