Specific embodiment

Reach the technical means and efficacy that predetermined purpose is taken for the utility model is further described, below in conjunction with attached drawing And embodiment, to specific embodiment of the present utility model, structure feature and its effect, detailed description are as follows.

Referring to shown in attached drawing 1-5, the indoor displacement air supply device of one of the utility model, including it is set to ground 19 Supporting element 14, offer return air inlet 11 and air inlet 15 respectively in the top and bottom of supporting element 14, wherein return air inlet 11 is used for 14 surrounding air of supporting element is absorbed, as return air, especially supporting element 14 nearby close to the indoor return air in personnel activity region；Into Air port 15 derives from damping air conditioner for absorbing the fresh air being sent into below ground 19 or processing wind, the fresh air or processing wind Group；Wherein, the preferred solution air-conditioning damping unit of damping air-conditioner set.

It is convenient for air-supply to realize, in the present embodiment, return air inlet 11 and air inlet 115 is respectively arranged on to the top of supporting element 14 Portion and bottom realize lower part air inlet, top return air, the purpose of centre mixing, and then realize the air-flow ratio in air inlet and mixing Smoothly, high-efficient feature, and return air inlet 11 is set to top, convenient for absorbing more indoor return airs.

In the present embodiment, in order to which by fresh air or processing wind, indoor return air reaches is sufficiently mixed effect with treated, also exist Mixing chamber is equipped between return air inlet 11 and air inlet 15, specifically, mixing chamber is to be set between return air inlet 11 and air inlet 5 Virtual cavity after necessarily being mixed by mixing chamber, then is sent from the air outlet 12 of 14 side of supporting element when fresh air or return air enter Out, it enters the room.In the present embodiment, air-supply is by side, and return air enters through top, and the entrance of fresh air or processing wind is logical Bottom is crossed, mainly considers the arrangement in various pipelines and air port；For supporting element 14, it is only plane frame Frame structure or space frame structure, no matter which kind of structure, side can open up air outlet position and choice it is bigger, and Air supply device in the utility model, emphasis are air-supplies, therefore air outlet needs to select to be convenient for open up and the biggish position of area, Therefore selection side；And fresh air or processing wind, then it is the wind supplied by air-conditioner set, needs to be distributed at air supply device, and lead to Beneath pipeline is crossed, space is saved；For indoor return air, since another feature of the present embodiment is carried out to indoor return air Temperature Treatment, therefore it necessarily derives from interior, and the top or side of supporting element 14 may be selected, and side has been used to blow, therefore It is set to top, and return air amount is larger, can handle more indoor return airs.

In the present embodiment, the outermost of supporting element 14 is equipped with the first air outlet 1 and the second air outlet 2, wherein the first air-supply Mouthful 1 and second air outlet 2 be symmetrical arranged, the air absorbed from the return air inlet 11 and air inlet 15 by after mixing chamber mixing from First air outlet 1 and the second air outlet 2 are sent into interior, realize the effect of multipath submitting after return air and fresh air mixing.

In order to better meet the demand of occupied zone, in the present embodiment, the height of supporting element 14 is set as 2 ± 0.5 meter.Most of zone of action of indoor people is 2 meters or so, and supporting element 14 is 2 meters, and the indoor return air of processing is also 2 meters of left sides Right, meet the temperature and humidity requirement of occupied zone.

In the present embodiment, the supply air temperature sent out from air outlet is 20 ± 2 DEG C, this temperature is indoor preferable temperature, It can satisfy the temperature requirements of occupied zone, temperature is too high, then is easy to cause indoor seasoning, causes discomfort；And temperature is too low, It is excessively cold, it is unsuitable for human body.

In the utility model, the mode that 14 bottom of supporting element takes foundation bolt fixed is fixed on ground 19.

In the present embodiment, supporting element 14 can be the frame of tetragonal body, specially metal framework, and effect is support and consolidates Fixed internal some devices, specific structure can be skeleton construction.It is because its intensity is high using metal framework, stress is good.

In the present embodiment, supporting element 14 is set to ground 19, i.e., entirely displacement air supply device is set on ground 19, right When indoor return air carries out temperature adjusting, treatment in situ, without the air-supply of long distance delivery air-conditioning system, operation energy consumption is lower, and And system initial cost is smaller.The device is in use, can according to actual needs, in different spaces send coiled displacement The quantity of wind apparatus, distribution are adjusted.

Embodiment 1

Referring to shown in attached drawing 1-5, in the present embodiment, including supporting element 14, the mixing chamber of 14 bosom position of supporting element, And the return air inlet 11 and air inlet 15 of 14 top and bottom of supporting element, and it is set to the blower 10 above mixing chamber；Its Cross flow fan, centrifugal blower or axial flow blower etc. can be selected in middle blower 10.

When blower operating, forced convertion, and the size by adjusting rotation speed of fan are formed, can be good at adjusting back Air quantity.The two strands of wind come in from return air inlet 11 and air inlet 15, send out after being mixed by mixing chamber.

If the speed that indoor return air flows into the device is slow without blower 10, that is, the return air entered is few, low efficiency.

Further, in this embodiment blower selects frequency conversion fan, frequency conversion fan, can be certainly by adjusting working frequency The dynamic air quantity for adjusting blower, and then realize increasing or decreasing for processing return air amount.

When the indoor displacement air supply device in the present embodiment is built for exhibitions, it is arranged on each layer of ground 19 several A displacement air supply device；Since the construction personnels such as conference and exhibition center are more, load is larger, if setting air-conditioner set carries out Wind Volume Return air processing, then need in each layer of several backwind tubes of setting, and occupied space is very big, while also needing that treated is empty For gas by transmission & distribution such as blower, air hoses to replaceable ventilating opening, the pipeline needed is more, and the energy consumption in system conveying is higher, initial cost It is larger；And the displacement air supply device in the present embodiment is used, return air needed for each layer directly is absorbed from return air inlet 11, then By the temperature-adjusting device in device, after being carried out in situ Temperature Treatment, is sent out from air outlet 12, realize room temperature very well Adjusting, and save space, initial cost is lower.Fresh air or processing wind are delivered to supporting element 14 by air supply tube, by bottom It is sent into, then indoor return air mixes with treated, is sent out, is reached to room air from air outlet 12 by the effect of blower 10 Carry out the purpose of Temperature and Humidity Control.Because fresh air volume is relatively small, therefore air hose the space occupied and initial cost also can be much smaller.
