Description

Ventilation plant

The ventilation plant that the present invention relates to promote the ventilation of underground parking field boundary or improve extensive space heating effect.

Be arranged in the underground underground parking field boundary of building, be full of the waste gas of automobile easily, legal strict ventilation volume requirement is arranged.Therefore, must pay special attention to ventilation.In addition, in the indoor swimming pool of high ceiling board, gymnasium, hall, lobby, restaurant etc. were arranged, the warm air frequent during heating must take some ways that this warm air is scattered up, to improve heating effect.

In the prior art, this kind taken a breath or the method for improving heating effect has following several.

(1) at indoor large-scale steam line and the exhaust duct of being provided with dispersedly as far as possible.

(2) not only adopt air supply fan, ventilating fan, the ventilation fan that has adopted small-bore pipeline also is set.This small-bore pipeline for example is configured in the smallpox board, on this pipeline,, make from ventilation to promote the air of fan in pipeline, to circulate, penetrate jet flow from above-mentioned nozzle with appropriate intervals setting and the nozzle that stream in the pipeline communicates, in indoor formation forced convection, to promote ventilation.

(3) a plurality of small-size shaft flow fans are set to promote ventilation.

But, in the method for above-mentioned (1), on big card, wall, large-sized supply and exhaust pipeline must be arranged.Especially under the situation of underground parking field boundary ventilation, because the ventilation air quantity is big, low ceiling surface is occupied by large-scale supply and exhaust pipeline, the setting of miscellaneous equipments such as influence illumination, automatic water sprayer.In addition, must cross over the position of beam at pipeline, it constructs complicated.

The method of above-mentioned (2) is compared with method (1), though construction is simple, through beam is also easy, but still need carry out the construction of pipeline.

The method of above-mentioned (3) though do not need to carry out the construction of pipeline, in order air not to be assembled and to be formed air stream indoor, needs considerable fan.And axial fan itself is identical with airflow direction, under the situation that will form predetermined air stream, owing to other machine has been installed, so it is provided with the suffered restriction of field boundary.And because the installation direction of fan not all is same direction, irregular in the configuration, outward appearance is also plain.

In order to solve above-mentioned the problems of the prior art, the applicant had before opened in flat 7-31824 number the Japanese patent gazette spy and disclosed a kind of ventilation plant.In this ventilation plant, the hollow pliability supporting mass of supporting nozzle is set on a side plate of chamber, passing through the pliability supporting mass, sprays from nozzle from the suction port inhaled air by blower.Like this, do not need pipeline construction, and, the jet direction that from nozzle, sprays can freely be changed.An available device is to a plurality of direction ejection jet flows.Therefore, can improve greatly degrees of freedom is set.

But in the parking field boundary, vehicle is perpendicular to out all generally that Inbound (vehicle lane) stops.Therefore, when the ventilation plant that adopts above-mentioned spy to open flat 7-31824 communique announcement was taken a breath, ventilation plant was provided at predetermined intervals on vehicle lane, formed the main air-flow that transports on vehicle lane.

In addition,, take a breath in order to make the air diffusion of 2 direction parking areas that are positioned at vertical vehicle lane, preferably with respect to device direction is set, from the plane, 90 ° of directions ground sprays other jet flow to foreign side towards both sides respectively,

In order to realize this point, in the above-mentioned existing ventilation plant, though as long as the pliability supporting mass of the two ends nozzle among three nozzles from the plane 90 ° of outside lateral bendings respectively, according to the difference of the material of pliability supporting mass, can not bend to 90 ° sometimes.In addition, even can be bent to 90 °, the length of pliability supporting mass own also must be longer.Like this, cause device to maximize, gain in weight.Therefore, still need and do some improvement.

The present invention makes in view of the above problems, and its purpose is to provide a kind of new ventilation plant.This ventilation plant has kept above-mentioned spy to open the advantage of flat 7-31824 ventilation plant that communique discloses, and the jet flow of the 90 ° of direction ejections in both sides to the left and right, and apparatus structure compactness is easily carried facility.
