Description
Technical field
The present invention relates to a kind of central air-conditioning cold air distribution device
Background technology
In the existing central air-conditioning field, ice cold-storage and warm and humid branch control central air conditioner system, all relate to Cryogenic air or new wind air-supply technical problem, the general practice is that Cryogenic air or new wind are from the common air outlet of airduct in being arranged on the room, blinds air outlet for example, grid air outlet, air diffuser etc. are directly sent in the room, theoretical and engineering practice shows that there is following defective in the air supply mode of existing Cryogenic air or new wind:
1, air themperature in the room and water capacity all are higher than described Cryogenic air or new wind, directly blow by air outlet, there is the backflow mixed zone in the deckle board periphery in the air port, air themperature and water capacity are higher than institute's Cryogenic air of sending or new wind in this mixed zone, therefore, on the lower air outlet deckle board of temperature, produce condensate water, not only influence attractive in appearancely, also can influence the normal use in room.
2, no matter be the cold air distribution of ice storage central air-conditioning, or the new wind of low temperature of warm and humid branch control central air-conditioning, all need to regulate the air quantity of sending into the room according to the actual demand of space cooling load and humidity load, the direct air supply mode in existing airduct and air port is because of wind speed height in the airduct, the modulability of each room air quantity is poor in the wind system, interfere with each other greatly, thereby it is uneven each room air-supply usually to occur, not only influence the comfortable of air-conditioned room, also waste air conditioning energy consumption.
Summary of the invention
At the problems referred to above, the invention provides a kind of have all press and induce mixed function, and can regulate the air-supply arrangement of Cryogenic air or new wind air quantity.
For achieving the above object, the present invention by the following technical solutions:
A kind of cold air distribution device of the present invention comprises air intake surge tank structure division, regulates induced draught box structure part and built-in heat insulation layer, and above-mentioned two-part structure is cut apart the mutual flap select of plate by neutrality and connect, and constitutes single unit system of the present invention.Described air intake surge tank structure division comprises flange air intake short tube and is cut apart plate by edge-on box plate, upper box plate, lower box plate, preceding upright box plate, the upright box plate in back and neutrality and connect and compose surge tank through flap mutually, one end flanges of described flange air intake short tube and the open circumferential select of described edge-on box plate connect, and constitute air intake surge tank structure division of the present invention; Described adjusting induced draught box structure partly comprises regulates the jet air channel, the lower shoe structure, last top arc, front vertical plate and back vertical plate, described adjusting jet air channel comprises that neutrality cuts apart plate, air quantity electric control valve and jet convergent air port, one end flanges of described air quantity electric control valve and neutrality are cut apart plate open circumferential select and are connect, the big distolateral flange select in the other end flange of this air quantity electric control valve and jet convergent air port connects, constitute and regulate the jet air channel, described lower shoe structure comprises lower shoe, the return air air port, air-supply air port and Ω shape back pressure plate, described return air inlet and air outlet embed two opening parts of lower shoe respectively, return air inlet, the air outlet periphery flange connects with lower shoe two open circumferential selects respectively, described Ω shape back pressure plate places on the lower shoe of return air inlet and air outlet centre, two flaps of Ω shape back pressure plate and lower shoe select connect, and constitute the lower shoe structure; Described adjusting jet air channel cuts apart the lower flap portion of plate by its neutrality and the return air oral-lateral flap select of lower shoe structure connects, described neutrality is cut apart other three flaps of plate and is connect with a flap select of last top arc, front vertical plate and back vertical plate respectively, the lower flap portion select of the air-supply oral-lateral flap of described lower shoe structure and last top arc connects, former and later two of described lower shoe structure are analysed plate and are connect with the flap select of front vertical plate and back vertical plate respectively, the flap of other plates and plate connects through the counterpart select, constitutes described adjusting induced draught box structure part; Described built-in heat insulation layer be meant gluing in a kind of cold air distribution device of the present invention inside (except that damper blade and return air inlet, air outlet grid leaf) can touch carry insulation material on the air metal surface.Adjusting jet of the present invention air channel, Ω shape back pressure plate, return air inlet and casing constitute jet and induce return air function chamber, and by Ω shape plate, air outlet and casing constitute mixed ventilation function chamber.
Operation principle of the present invention is as follows:
Cryogenic air or new wind enter in the surge tank from air inlet, reduce to low speed (general wind speed is 1m/s) from high speed (being generally 6m/s), the most of static pressure that changes of its dynamic pressure, play the effect of all pressing with voltage stabilizing, be convenient to control valve and regulate the air output of sending into the room, be decelerated all Cryogenic air after pressing or new wind and enter the air port of contracting, jet Zhejiang through control valve, quilt is speedup progressively, to the outlet of jet air port, form high velocity air and inject adjusting induced draught box cavity of the present invention, because high-speed jet enters in the chamber, its speed is anxious to be subtracted, need air in a large amount of hybrid chambers, therefore, casing forms negative pressuren zone between outlet of jet convergent air port and the Ω shape back pressure plate, and room air is drawn onto negative pressuren zone through return air inlet, satisfy jet and mix demand, slow down behind the mixing back air-flow intensification humidification, flow through Ω shape back pressure plate and another part casing and form zone of positive pressure, the air outlet in zone of positive pressure is sent into the room, thus, constituted operation principle of the present invention.
According to technique scheme, more existing Cryogenic air air supply mode, the present invention obtains following technique effect:
1, owing to be provided with surge tank, the end in the pipe network of blowing at a high speed plays all presses pressure stabilization function, has solved each room air-supply and has been difficult for regulating the problem uneven with air-supply.
2, owing to be provided with electric control valve, thereby the size of room air quantity can be sent into, the invalid energy consumption of air-conditioning can be saved according to the refrigeration duty in room and the adjusting of humidity load demand.
3, since in the room air mix in air-supply arrangement with Cryogenic air, and install inner metal surfaces all gluing insulation material, therefore, can not produce condensate water installing inside.Because what return air inlet entered is space air, therefore the mixing air after the intensification that air outlet sent, all can not produce condensate water at these two air port frames, thus, solves the condensate water problem of existing air supply mode.
