Abstract
A chair blowing-in and current dispersing device with an average pressure device relates to a dispersing device which is used on the fixing chair for chair blowing-in in the cinema and showplace, the gymnasium and the reading room, etc. The utility model is provided with an average pressure device in the original chair blowing-in and current dispersing device, the average pressure device presents a cylinder-shaped structure with small holes on the surface, and a cavum is positioned between the average pressure device and the current dispersing device, the cavum plays the role of a secondary hydrostatic pressure case. the non-uniformity dynamical pressure can be converted into the uniformity hydrostatic pressure in space after the wind is blown in through the cavum, thus making the wind speed blow out of the current dispersing device uniformity without any changes along the height direction, so as to solve the problems effectively of that, the wind speed of the current dispersing device is non-uniformity along the height direction in the wind blowing-in under the chair, thus enhancing the warm comfort for the seating people.
Description
Technical field
The utility model relates to a kind of ventilation unit, relate in particular to a kind of in the cinema, there is the air diffuser that uses in the seat air supply of fixed seating in gymnasium and reading room etc.
Background technology
Seat down air-supply belongs to a kind of of replacement aeration, be in recent years in the cinema, there is the novel draft type of the place utilization of fixed seating in gymnasium and reading room etc.Seat air-supply down is to send into the fresh air that is lower than room temperature from the below in room, because the heat effect of thermals source such as personnel's equipment, fresh air is heated rising, takes away indoor heat, pollutant simultaneously, discharges from the return air inlet that is positioned at the higher position, room.Send the box-like ventilating ratio of top back-mixing with general top, seat air supply can provide better air quality in the personnel respiratory region, and Temperature Distribution is more energy-conservation up and down because of forming the space simultaneously.The air-supply air diffuser generally combines with seat under the conventional seat, and air diffuser not only serves as the air port but also serve as chair and support.Air diffuser is column type or square, and certain height is arranged.Its air-out speed is along very inhomogeneous on the short transverse, and is low down high.Under certain air output,, usually cause the personnel's of taking a seat blowing feeling because the local air-out speed of air diffuser is excessive.The air-out speed of air diffuser influences personnel's thermal comfort, and same air diffuser air-out speed is determined by air output.For the thermal comfort that guarantees personnel usually reduces air output, might not satisfy the requirement of load.
The utility model content
The purpose of this utility model provides a kind of new seat air supply air diffuser, can solve under the seat in the air-supply air diffuser air-out speed along the uneven problem of short transverse, thereby further improve the personnel's that take one's seat thermal comfort.
The purpose of this utility model is achieved by the following technical solution:
A kind of seat air supply air diffuser that has voltage balancer comprises air diffuser, it is characterized in that: establish a voltage balancer in air diffuser, described voltage balancer has the cylindrical structure of aperture for the surface, and and air diffuser between leave cavity.
Described voltage balancer adopts circular cone type tube or cylinder type tube.
The utility model is owing to be provided with a voltage balancer in the inside of original air-supply air diffuser, and the cavity between voltage balancer and air diffuser has served as the effect of secondary plenum chamber, convert uneven dynamic pressure to compare uniformity on the space static pressure behind this cavity of air-supply process, make and go out the wind speed of stream along the almost not variation of air diffuser short transverse from air diffuser, compare uniformity, air diffuser air-out speed has further improved the personnel's that take one's seat thermal comfort along the uneven problem of short transverse in the air-supply thereby solved effectively under the seat.
Description of drawings
The structural representation of the seat air supply air diffuser of a kind of built-in circular cone type tube voltage balancer that Fig. 1 provides for the utility model.
Fig. 2 is a kind of outside drawing that has the seat air supply air diffuser of pyramid type voltage balancer.
Fig. 3 is air output 50m
3During/h, air diffuser goes out to flow wind speed along the comparison diagram that distributes on the short transverse when adopting circular cone type tube voltage balancer shown in Figure 1 and no voltage balancer.
Fig. 4 is air output 100m
3During/h, air diffuser goes out to flow wind speed along the comparison diagram that distributes on the short transverse when adopting circular cone type tube voltage balancer shown in Figure 1 and no voltage balancer.
The specific embodiment
The seat air supply air diffuser that the utility model provides is that a voltage balancer 1 is set in former air diffuser 4, and this voltage balancer adopts cylindrical structure, is preferably circular cone tube or cylindrical drum, and has a plurality of apertures 2 in its surface.Voltage balancer should and air diffuser between leave certain cavity 3.The air of sending to from seat bottom plenum chamber or air channel arrives voltage balancer 1 earlier, is flowed out by the aperture 2 of voltage balancer 1, enters in the cavity 3 that voltage balancer 1 and air diffuser form, and is flowed out by air diffuser 4 then.Because during fluid flows, static pressure and dynamic pressure can be changed mutually, and the cavity between voltage balancer and air diffuser has served as the effect of secondary plenum chamber, air-supply is through converting uneven dynamic pressure to behind this cavity on the space the relatively static pressure of uniformity, makes that to go out the wind speed of stream from air diffuser almost consistent along the air diffuser short transverse.
Embodiment:
Voltage balancer adopts the circular cone cylindrical structure, under identical air output, has the air diffuser maximum of voltage balancer to go out to flow the air diffuser maximum that wind speed is far smaller than no voltage balancer and goes out to flow wind speed.For example, when air output be 50m
3During/h, it is 2.6m/s that the maximum of the air diffuser of no voltage balancer goes out to flow wind speed, and it is 0.25m/s that minimum goes out to flow wind speed, and wind speed increases along with the increase of height.And the maximum that the air diffuser of voltage balancer is arranged to go out to flow wind speed be 0.46m/s, it is 0.35m/s that minimum goes out to flow wind speed, the wind speed with altitude direction does not almost change, relatively uniformity (seeing accompanying drawing 3).When air output is 100m
3During/h, it is 5.7m/s that the maximum of the air diffuser of no voltage balancer goes out to flow wind speed, and it is 0.5m/s that minimum goes out to flow wind speed, and wind speed increases along with the increase of height.And the maximum that the air diffuser of voltage balancer is arranged to go out to flow wind speed be 1.5m/s, it is 0.4m/s that minimum goes out to flow wind speed, the increase of wind speed with altitude slightly increases, but still little (seeing accompanying drawing 4).Therefore, the seat air supply air diffuser that has a voltage balancer has guaranteed also under the prerequisite of burden requirement that the personnel of taking a seat are to demand for thermal comfort satisfying.
Claims (2)
1. a seat air supply air diffuser that has voltage balancer comprises air diffuser, it is characterized in that: establish a voltage balancer in air diffuser, described voltage balancer has the cylindrical structure of aperture for the surface, and and air diffuser between leave cavity.
2. according to the described seat air supply air diffuser of claim 1, it is characterized in that: described voltage balancer adopts circular cone type tube or cylinder type tube.
