Abstract
The invention discloses an air supply system below a seat and relates to an air conveying system, for purpose of solving the technical problem of uneven speed and temperature of airflow sent out by the prior air supply systems below seats. The air supply system below the seat comprises at least one seat and a plenum box arranged below the seat. The plenum box is communicated with an air supply device, an air opening is arranged below the seat, and a flow guide device is arranged in the plenum box and at the front clearance of the air outlet of an air supply device. The guide device is an opening baffle with multiple through holes. The diameter of the opening baffle is larger than that of the air outlet of the air supply device. The invention is mainly applicable to large places such as theatres or stadiums in which a great number of seats are arranged.
Description
Technical field
The present invention relates to a kind of air delivery system, be specifically related to the supply air system under the seat in a kind of large space environment.
Background technology
Supply air system under the seat is mainly used in the large space environment, as seats such as cinema or stadiums many occasions is set.Supply air system is transported to air-flow in cinema or the stadiums under the seat, guarantees that cinema or stadiums temperature are suitable, with fresh air, make spectators more comfortable view and admire program or match.
As shown in Figure 1 and Figure 2, the supply air system under the existing seat comprises seat, auditorium and the plenum chamber that is located under the seat, and plenum chamber is communicated with air-supply arrangement, and the seat has the air port, and the air port is provided with air diffuser or swirl diffuser.The air-flow of air-supply arrangement output is through plenum chamber, and following air port enters the purpose that reaches adjusting cinema or stadiums air in cinema or the stadiums from the seat at last.
Supply air system under the existing seat, though reached the purpose of regulating cinema or stadiums temperature and air to a certain extent, but have following several problem at least: air-supply arrangement is communicated with plenum chamber, very big near tuyere air volume under the seat, auditorium of air-supply arrangement, and it is very little apart from tuyere air volume under the air-supply arrangement seat, auditorium far away, even there is not wind, so air-flow wind speed and temperature that supply air system is sent are uneven, this causes in cinema or the stadiums uneven in temperature, and the energy consumption of air-conditioning system is big but regulating effect is not remarkable.
Summary of the invention
The invention provides the supply air system under a kind of seat, solved air-flow wind speed and non-uniform temperature that the supply air system under the existing seat is sent, the technical problem uneven in temperature that produces when causing regulating the air in cinema or the stadiums.For achieving the above object, the present invention has adopted following technical scheme:
Supply air system under this seat, comprise at least one seat and the plenum chamber that is located under the seat, described plenum chamber is communicated with air-supply arrangement, described seat has the air port, in plenum chamber, the preceding splaying of air outlet of air-supply arrangement is provided with guiding device, described guiding device is the perforated baffle that is provided with a plurality of through holes, and described perforated baffle is greater than the bore of the air outlet of air-supply arrangement.
Be provided with guiding device between air-supply arrangement and the air port in the supply air system under the seat compared with prior art of the present invention, this guiding device can stop that mass air flow directly enters the air port near air-supply arrangement, force air-flow to enter other spaces of plenum chamber, also guarantee that an amount of air-flow passes guiding device and discharges from the air port near air-supply arrangement simultaneously.The air-flow that forms wind speed and non-uniform temperature state after guiding device just outputs to air-supply arrangement in the plenum chamber like this is converted to the air-flow of uniform state, make the air-flow wind speed in input cinema or the stadiums and temperature is more even and temperature suits, thereby air-flow wind speed and non-uniform temperature that the supply air system under the existing seat is sent have been solved, the technical problem uneven in temperature that produces when causing regulating the air in cinema or the stadiums.

Description of drawings
Structural representation when Fig. 2 is provided with air diffuser or swirl diffuser for the air port of the supply air system under the seat in the prior art shown in Figure 1;
Fig. 3 is the cross-sectional configuration schematic diagram of the supply air system under the seat of the present invention;
Fig. 4 is an air port cross-sectional configuration schematic diagram in the supply air system under the seat of the present invention shown in Figure 3.
The invention provides the supply air system under a kind of seat, air-flow wind speed and temperature that this supply air system is sent are even, and effect is remarkable when regulating the cinema be provided with the air-conditioning system or the air in the stadiums.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further elaborated:
As shown in Figure 3, supply air system under this seat, comprise five arrange seatses 1, the position height of five arrange seatses 1 is step-like and successively decreases, seat 1 has air port 2, and the seat also is provided with plenum chamber 51 time, and plenum chamber 5 is communicated with airduct 41, the air inlet of airduct 41 is that air-conditioner air supply device is connected with air-supply arrangement 4, and the air-out direction of air-conditioner air supply device parallels with the direction in air port 2.In plenum chamber 5, the air outlet 42 preceding splayings of air-conditioner air supply device are provided with the perforated baffle that guiding device 3 promptly is provided with a plurality of through holes, perforated baffle is greater than the air outlet 42 of air-conditioner air supply device and the bore of airduct 41, the direction that is provided with of perforated baffle parallels with the increasing or decreasing direction at seat, perpendicular with the air-out direction of airduct 41, the percent opening of perforated baffle (percent opening is the ratio that the area of finger-hole accounts for the gross area of plate) is 30%～50%, is preferably 40%.The direction that is provided with of the through hole of perforated baffle parallels with the air-out direction of airduct.
As shown in Figure 4,22 swirl diffuser is taken over for being provided with the rear portion in air port 2, its rear portion is provided with the rear portion and takes over 22, air port 2 is run through and is arranged in the concrete wall 24, the rear portion is taken over 22 and is provided with the orifice plate that fairing 21 promptly is provided with a plurality of through holes, orifice plate can form less than 20 handkerchief resistance air pressure differences, and the direction that is provided with of through hole parallels with the direction that is provided with in air port 2.Seat 1 downstairs formula swirl diffuser is adopted in air port 2, and air port 2 is arranged on the vertical plane of the ladder that seat 1 is installed in the present embodiment.Obviously, also can be arranged on the level ground of the ladder that seat 1 is installed.
After air-conditioner air supply device is transported to plenum chamber 5 by airduct 41 with air-flow, this perforated baffle stops that mass air flow directly enters the air port 2 near air-conditioner air supply device, force air-flow to enter other spaces of plenum chamber 5, also guarantee that an amount of air-flow passes perforated baffle and discharges from the air port 2 near air-conditioner air supply device simultaneously.After 2 rear portions, air port adapter 22 receives air-flow, again by the through hole on the orifice plate, orifice plate with resistance has guaranteed 1 time air port, each seat, 2 air quantity basically identicals, swirl diffuser under the seat 1 is more even with the air-flow conversion, wind speed and temperature uniform airflow are input in cinema or the stadiums, guarantee that cinema or stadiums temperature are suitable, with fresh air, make spectators more comfortable view and admire program or match.
