Abstract
The utility model discloses an air-return fireproof silence chamber and relates to equipment which is used matching with an air conditioner. The provided air-return fireproof silence chamber aims at solving the problem that the air returning effect of the air conditioner equipment is poor due to the equipment such as a fireproof valve, an air volume adjustment valve, a silencer and the like of a present large-volume air supply and return air-conditioning system have narrow installation space. The silence chamber comprises a silencing shell body which adopts the structure of a rectangular solid. One surface of the silencing shell body is an air inlet, the other two surfaces in the direction vertical to the surface where the air inlet is located are air outlets, and fireproof adjustment valves are arranged at the positions of the air outlets. The silence chamber integrates the fireproof valve, the silencer and the air return volume adjustment in an air-conditioning air return system into one, and changes direct one-face air return into indirect two-face air return, so as to greatly save the equipment space of the air return system. As air return flow is not directly led to an air return opening of the air conditioner, but is carried out silencing processing, the silence chamber can effectively stop noise transmission at the same time as adjusting the air return volume. The air-return fireproof silence chamber has the characteristics of novel structure, convenient utilization as well as maintenance and beautiful appearance, and is beneficial for being popularized and applied.
Description
Technical field
The utility model relates to a kind of and the matching used equipment of air conditioner.
Background technology
Many large-scale big air quantity air blow and return air-conditioning systems civilian and industrial building (as conference centre, large-scale showroom, hospital, the large-scale master-control room in cinema and factory etc.) have very strict requirement to fire-fighting and noise, the system that has directly with air conditioning equipment room as the return air plenum chamber.But the big air quantity air blow and return air-conditioning system of these large-scale civilian and industrial buildings is because job site and device space position are limited, the ceiling void is little, the equipment room is crowded, to equipment such as fire resisting damper, volume damper and silencer will be installed between the air conditioner equipment simultaneously very big difficulty is arranged at return air duct, the equipment that has is forced to save, and makes these Air-conditioning Engineerings exist that return air weak effect, the bad adjusting of air quantity, noise are big, the problem of the difficult installation of fire resisting damper.
The utility model content
At now big air quantity air blow and return air-conditioning system when mounted, installation space such as its fire resisting damper, volume damper and silencer are narrow and small, make the problem of air conditioner equipment return air weak effect, the utility model that a kind of return air fire prevention silencer box is provided, can address the above problem preferably.
Described purpose is achieved by the following scheme:
Return air fire prevention silencer box described in the utility model is installed in the air conditioner air return system between the air conditioner equipment.It comprises the noise elimination housing of being made by quieter material of rectangular structure, surface of noise elimination housing is provided with the aluminium alloy air inlet, the air inlet place is provided with blade, and described blade can be arranged to individual layer fixed blade or double-deck fixed blade or direction adjustable vane as required; With two surfaces in addition of air inlet place surface vertical direction be air outlet, described air outlet place is provided with the fire prevention control valve.Adopt screw to be connected between aluminium alloy air inlet and the noise elimination housing, adopt between the air inlet of fire prevention control valve and the noise elimination housing and weld or rivet.
During the utility model has been avoided in the past effectively, all drawbacks of existing in the return air stage of large-size air conditioning system, it is as follows to have advantage:
1, fire resisting damper, silencer and the return air blast regulator in its collection air-conditioning air return system is one, and changing the direct return air of one side is the indirect return air in two sides, the device space of having saved air return system greatly.
2. the design aspect airflow noise-elimination meets the needs of environment fully; The processing of eliminating the noise earlier makes this product can effectively stop the transmission of noise when regulating the return air amount because the return air air-flow does not directly lead to the return air inlet of air conditioner.
3. guaranteed that air return system also can install fire resisting damper in worst locus, prevented that to reach zone isolation the intensity of a fire and flue gas from spreading expansion; Novel structure, working service is convenient, and is specious, is beneficial to and applies.

The specific embodiment
Elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.
The utility model is installed in the air conditioner air return system to (generally being installed on the wall between air conditioner equipment room and the air-conditioned room) between the air conditioner equipment.Referring to figs. 1 through Fig. 4, it is the noise elimination housing of a rectangular structure, and the noise elimination housing is to be made by known quieter materials such as galvanized sheet, perforated plate, noise elimination cotton, imperial framves.Surface of noise elimination housing is an air inlet, air inlet (being the return air inlet of air-conditioning system) is made for aluminum alloy materials, the air inlet place is provided with blade, described blade can be arranged to individual layer fixed blade or double-deck fixed blade as required, also the direction adjustable vane can be arranged to, the angle to air intake, the adjusting of air quantity can be realized like this; Air-conditioning return air enters in the housing by the air inlet of noise elimination housing, and air-flow begins noise reduction.
Be provided with air outlet with two surfaces in addition of surface, air inlet place vertical direction, be provided with the fire prevention control valve at the air outlet place.Return air after the process noise reduction is depressed into the both sides of noise elimination housing respectively, goes out behind the fire prevention control valve on both sides, enters the return air inlet of air-conditioning equipment again.The structure of fire prevention control valve is known, forms by valve body, blade and electric device, by electric device can control valve switch and adjust air quantity and the air intake direction of blade with the adjusting air intake.Therefore can regulate or close the fire prevention control valve easily according to the needs of whole air-conditioning system in use, enter air conditioner to stop return air.Adopt screw to be connected between aluminium alloy air inlet and the noise elimination housing, adopt between the air inlet of fire prevention control valve and the noise elimination housing and weld or rivet.The production of described fire prevention control valve meets GB15930-1995 " fire resisting damper experimental method ", and silencing apparatus production meets GB/T4760-95 " acoustic muffler measuring method ", and aluminum alloy material meets standard GB/T5237-93g and GB/T8013.
The utility model course of work is as follows: after air-conditioning return air enters this equipment, and the processing of at first in the noise elimination housing, effectively eliminating the noise, air-flow is depressed into both sides respectively then, enters the air conditioner return air inlet indirectly after the fire prevention control valve is gone out.When spring, autumn or arts demand air-conditioning send big portion or all outdoor new wind, can regulate or close the fire prevention control valve easily, enter air conditioner to stop return air.
Present embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can also carry out the part to it and change; so long as do not exceed the spiritual essence of this patent, all be considered as the replacement that is equal to, therefore all within the protection domain of this patent to this patent.
