Description
Technical field
Aeration device field is sent the present invention relates to classroom, more particularly to a kind of low noise classroom air jet system.
Background technology
Central air-conditioning system is installed in domestic classroom mostly, although installing air-conditioning can solve the humiture of interior
Control, but the air quality of interior cannot control, classroom densely populated place, be to ensure indoor air quality, major measure
It is ventilation, i.e., replaces the indoor air containing pollutant with treated outdoor air.Therefore for kindergarten and a medium and small scholar
The intensive occasion of member is very necessary to indoor offer fresh air.Most of occasions supply fresh air by door and window gap, but only lean on door and window
The faint fresh air of gap convection current, resh air requirement is general to be far not by far up to the mark less than 1%, and user often changes empty by door and window
Gas, causes temperature change big, uncomfortable, and fresh air is discontinuous and increases operating cost, therefore to ensure ventilation effect, should be in classroom
Middle installation VMC.
China's haze weather is increasingly severe in recent years, and conventional air conditioner fresh air processing system only has thick, intermediate air mistake
Filter, effective control can not be carried out to PM2.5.The fresh air that school is processed using conventional air conditioning system will the health of child make
Into harm, influence student's is healthy, therefore it is required that having to pass through purified treatment to the fresh air provided in classroom.
Conventional VMC needs to lay fresh wind tube, ajutage, backwind tube indoors, in order to ensure that air current composition is imitated
Really, it usually needs set multiple air outlets and carry out diagonal return air, it is this for classroom such that airduct pipeline is long
Building, then can take more space, and construction volume is larger, and the bright dress of airduct lays extremely unsightly.
Classroom is the quiet environment of comparing, and noise will certainly be produced when air flows in airduct, and Students ' Learning is produced
Interference.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of low noise classroom air jet system, easily with building
Thing is combined, and the device can eject the fresh air after purified treatment, and indoor each position can be reached after air circulation jet diffusion,
And reduce the generation of noise.
The technical solution adopted for the present invention to solve the technical problems is：A kind of low noise classroom air injection dress is provided
Put, including casing and duct collar, several adjustable Ball shape nozzles, described airduct are installed on the side wall of described casing
Interface is arranged in one end of duct collar, and quieter material layer is equipped with described box inside wall.
Preferably, the described casing keel frame being made including angle steel and the stainless steel being laid on the outside of keel frame
Plate or ABS plastic plate.
Include noise reduction mineral wool as another preferred, described quieter material layer, be laid on noise reduction mineral wool surface
Glass cloth and the microwell plate for fixing noise reduction mineral wool.
Further, described adjustable Ball shape nozzle is connected by the bead flange on the outside of it with casing.
Further, spout wind deflector is installed at the middle part air outlet of described adjustable Ball shape nozzle.
Further, one end that duct collar is disposed with described casing is disposed with reserved screw hole, described airduct
Pneumatic hose is socketed with the outside of interface.
Beneficial effect：The present invention relates to a kind of low noise classroom air jet system, its advantage is used for (1) plenum chamber
Stainless steel plate is made ABS plastic plate, can effective humidity, corrosion-resistant, and the impact resistance of ABS plastic plate, heat resistance,
Lower temperature resistance, chemical proofing and excellent electrical properties, electrical insulating property are preferable, and with excellent mechanical property.(2) static pressure
Set noise reduction mineral wool, glass cloth and microwell plate in case, generally one impedance composite muffler, can effectively absorption air in wind
The vibration produced during Bottomhole pressure and noise；(3) part dynamic pressure effectively can be changed into static pressure to obtain wind farther by plenum chamber；
(4) nozzle outlet air supply range is long, because air circulation jet is in course of injection, is constantly mixed into surrounding air, flow path is increased 3-5
Times, air supplying distance is long, and effect is good；(5) adjustable Ball shape nozzle is used, by manually adjusting air-supply airflow direction can be made to exist
Manual adjustment is carried out in the range of maximum 30 °；(6) by tight design calculating and emulation experiment, it is ensured that air-flow feeding room is each
While individual corner, it is to avoid the discomfort that air-supply air-flow blow-through student's head then causes.

Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As Figure 1-4, embodiments of the present invention are related to a kind of low noise classroom air jet system, including casing
1 and duct collar 2, several adjustable Ball shape nozzles 4, the described cloth of duct collar 2 are installed on the side wall of described casing 1
Put in one end of duct collar 2, quieter material layer is equipped with the described madial wall of casing 1.
Preferably, the keel frame that is made including angle steel of described casing 1 and being laid on stainless on the outside of keel frame
Steel plate or ABS plastic plate, two kinds of sheet materials respectively have advantage, can be selected according to actual conditions.
Include noise reduction mineral wool as another preferred, described quieter material layer, be laid on noise reduction mineral wool surface
Glass cloth and the microwell plate for fixing noise reduction mineral wool, this structure are more stable, in addition to reducing noise, it is possible to decrease air-flow exists
Flow resistance in airduct, it is ensured that air-flow uniformly sprays from two spouts.
Further, described adjustable Ball shape nozzle 4 is connected by the bead flange 3 on the outside of it with casing 1, installation side
