Below in conjunction with embodiment and accompanying drawing, the utility model is elaborated, wherein:
Fig. 1 is side structure schematic diagram of the present utility model.
Fig. 2 is Facad structure schematic diagram of the present utility model.
The partial structurtes schematic diagram of Fig. 3.
Fig. 4 is the structural representation of air intake noise reduction components of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further set forth the specific embodiment of the present utility model:
As shown in Figures 1 to 4, the utility model discloses the outdoor unit noise reduction components of a kind of central air-conditioning, it is characterized in that, comprise air intake noise reduction components and the air-out noise reduction components of being located at respectively central air-conditioning off-premises station air inlet place and air outlet place, described air intake noise reduction components comprises air intake sound insulation template and some air intake anechoic sheets; Described air-out noise reduction components comprises an air outlet silencing device frame and establishes some air outlet silencing sheets 2 of its inside.Between adjacent two air outlet silencing sheets, be provided with a space.
The sound insulation of air intake described in the utility model template 18 comprises one first air intake sound insulation template and the second air intake sound insulation template, the two ends of described air intake silencer element 17 are connected in described the first air intake sound insulation template and the second air intake sound insulation template, the angle that can conveniently regulate air intake silencer element to open by stirring this air intake silencer element, to adjust ventilation.
The sheet of air outlet silencing described in the utility model and described air intake anechoic sheet include two-sided expanded metal and are fixed on the flexibility sound absorption damping material of described two-sided expanded metal both sides.
Described air outlet silencing device frame comprises fixedly all-in-one-piece crown wall plate 1 and 2, framed side wallboard 5 and corner wallboard 6, between described crown wall plate and framed side wallboard, pass through roller 8, screw 9, roller fixture 10,12,14, locking nut, elastic cylindrical pin 13 is fixed into one, is also provided with a location-plate 7 on corner location-plate, is conveniently connected and fixed.
The anechoic sheet of air intake described in the utility model comprises connection, drive mechanism and the assembly thereof that can regulate air intake heat radiation angle, as shown in Figure 4.
Principle of noise reduction of the present utility model is by sound insulation module and silencer element, be air outlet silencing sheet and air intake anechoic sheet, assembling combination forms the class sealing noise elimination isolation booth to air-conditioner outdoor unit group, the machine operation of fan and electromechanics running noise are enclosed in noise elimination isolation booth, when the sound wave sending when noise source evokes air molecule vibration, its vibrational energy is passed to rapidly flexible sound absorption damping material in sound insulation sound absorbing module, this material is selected the sound-absorbing material of suitable unit weight according to noise source spectral characteristic, cause sound absorption damping material internal friction and the changing of the relative positions mutually, and make vibrational energy be converted into thermal energy consumption, fall, make unofficial biography acoustic noise reducing, thereby reach the object of noise reduction.Fan exhaust noise carries out sqouynd absorption lowering noise by being installed at specially the anechoic sheet on top, air port, and principle is the same.Anechoic sheet is designed to the composite construction of two-sided porous metal plate and flexible sound absorption damping material, and between anechoic sheet and anechoic sheet, reserved air exhaust passage is connected with outside atmosphere, does not affect air discharging and radiating when can reach noise reduction object according to noise reduction Demand Design.Normal ventilation and heat requirement when meeting air-conditioning unit operation, at the adjustable louvered air intake heat radiation of air-conditioning unit metal fin partial design angle anechoic sheet, anechoic sheet structure is with fan exhaust anechoic sheet, possessing can manual adjustments air intake fin angle of inclination function, can adapt to the asynchronous heat radiation requirement of outdoor temperature.
The utility model can improve the outdoor unit of central air-conditioning of the prior art because scattered distributing installation, the shortcoming of impacting to view aesthetic feeling, use this noise reducing apparatus, can realize the unified of outdoor unit of different sizes coordinates, also the design of external appearance spray finishing colored drawing can be carried out as requested, good vision landscaping effect can be formed.
The utility model can have been realized sound insulation gobo modularization, can realize " building block system " and split combination, and " PULL-IN-OUT " bolt-type plate connection mode of original creation, has save a large amount of metal connecting pieces, has also guaranteed the intensity of equipment.Owing to having realized modular assembling combination pattern, make installment work compare common mode and become very convenient, flexible, can assembledly realize, utilize unique assembling combination mode, realized the outdoor unit equipment of different central air-conditioning, standardized equipment provides, as long as provide the size of air-conditioner outdoor unit group, can automatically generate special-purpose modular size noise reducing apparatus.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
