Abstract
The utility model discloses a displacement ventilation system which comprises a fan case, an air pipe and an exhaust fan in sequence along the air flow direction, the displacement ventilation system also comprises an air guiding structure connected at the outlet of the air pipe, and the air guiding structure is arranged on the floor of a room. As the air guiding structure is arranged on the floor of the room, air is supplied from the lower part of the room, thus reducing the sense of draught; and air eddies are formed inside the air guiding structure and at an air supply outlet, thus enabling air supplied out of the air supply outlet to be more uniform. Therefore, the displacement ventilation system controls the discomfort of human body caused by air speed more effectively.
Description
Technical field
The present invention relates to a kind of ventilation system, relate in particular to a kind of ventilation system of substitute mode.
Background technology
Ventilation is one of method of air cleaning in a kind of effective holding chamber, such as public arenas such as industrial and mineral workshop, business offices, supermarket, market, cinema, theaters, air quality is quite muddy, and common purification style is exactly ventilation, and air supply mode promptly circulates.
Its cardinal principle is to utilize high-power blower that room air is taken away, simultaneously mends outdoor fresh air again, and indoor-outdoor air is ceaselessly alternately changed, and by the cyclical breathing to designated space 20-30 time/hour, the maintenance room air is fresh.
Its shortcoming be mainly reflected in following some:
1, energy consumption is big
Such as one 100 meters long 100 meters wide 15 meters high (150000m
3) factory building, if purify air, just need exhausting 15000m with the mode of ventilation
320 of the blower fans of/h, air-supply needs 15000m equally
320 of the blower fans of/h, 20 times the rate of ventilation that per hour could guarantee designated environment.
2, investment cost height
3, operating cost height
4, difficulty of construction is big
5, wind speed is fast, comfort level is low
Replacement aeration is a kind of new draft type.This air supply mode is compared with traditional mixed ventilation mode, can make the office work district obtain higher air quality, higher thermal comfort and has higher drafting efficiency.
But, existing displacement ventilation system with outdoor air pump to indoor after, be delivered directly to the workspace by the wind tube outlet that is fixed on the workbench, therefore blowing feeling is arranged, make human body sensory uncomfortable.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of more comfortable displacement ventilation system of human body sensory that makes.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of displacement ventilation system comprises air box, is connected the airduct and the independent ventilating fan that is provided with in this air box exit, and this system also comprises the air guide structure that is connected this wind tube outlet place, and this air guide structure lands installation in the room.
For above-mentioned displacement ventilation system, this air guide structure is the jar shape structure of hollow.
For above-mentioned displacement ventilation system, the sidewall of this air guide structure has air outlet.
For above-mentioned displacement ventilation system, this air outlet is the numerous circular holes that are evenly distributed on this air guide structure sidewall.
Advantage and characteristics that technical solutions of the utility model are main are:
1, by the installation of landing of air guide structure, reduces blowing feeling from the air-supply of bottom, room;
2, form eddy current by air at air guide structure inner formation eddy current and at the air outlet place, the wind that air outlet is sent is more even.
3, therefore, controlled wind speed sense of discomfort that human body is produced more effectively.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model displacement ventilation system;
Fig. 2 a, 2b and 2c are respectively front view, top view and the rearviews of an embodiment of air guide structure in the displacement ventilation system of Fig. 1.
The specific embodiment
As shown in Figure 1, displacement ventilation system of the present utility model comprises air box 11, is connected the airduct 12 in air box 11 exits, the air guide structure 13 that is connected airduct 12 exits and the independent ventilating fan 14 that is provided with.Ventilating fan 14 is installed in the top in room.
The main improvement of this displacement ventilation system is to have increased air guide structure 13.Air guide structure 13 is a kind of jar shape structure of hollow and console mode installation in the room.
Displacement ventilation system of the present utility model is drawn into airduct 12 inlets by air box with outdoor air, is transported to through airduct 12 and also forms very big eddy current in the air guide structure 13 therein.Air outlet 131 by air guide structure 13 sidewalls is blown in the bottom, room with low speed, and air outlet 131 is the numerous circular apertures that are evenly distributed on air guide structure 13 sidewalls, forms eddy current at the circular hole place.Therefore, from air outlet 131 balanced ventilations.Air-flow slowly moves up with the state of the piston flow of similar laminar flow, arrives the influence that certain altitude is subjected to thermal source and top board, and turbulent phenomenon takes place, and produces the turbulent region.Produce the heating power lamination at about 1.8～2.0 meters height place air-flows, two zones occur: bottom one-way flow district and mixed zone, top.Air themperature field and concentration field have very significantly different qualities in these two zones, one-way flow district, bottom exists tangible vertical temperature gradient and concentration gradient, temperature field, turbulent mixture district, top and concentration field are then relatively more even, near the temperature and the pollutant levels of air draft.Momentum that this ventilation form is blown no longer fully control and mainly be subjected to the hot buoyancy lift effect of thermal source, the plume that thermal pollution source forms rises because of density is lower than surrounding air.Constantly entrainment surrounding air in the plume uphill process and flow to the top.If the plume flow,, will some hot foul smell flows down to fall and returns according to the principle of continuity greater than air output at nearly ceiling place.Therefore form the turbid air layer of heat at the top, last, these hot turbid air are discharged to outdoor by ventilating fan 14.
Therefore, theoretically, displacement ventilation system will guarantee that layer height is more than the workspace.Displacement ventilation system of the present utility model is owing to increased air guide structure 13, thereby air supply velocity is minimum and the air-supply turbulence level is low, can guarantee that most of regional wind speed is lower than 0.15m/s in the workspace, does not produce blowing feeling; Secondly, fresh clean air is directly sent into the workspace, earlier through human body, so just can guarantee that human body is in the air ambient that cleans relatively, thereby improve the air quality of workspace effectively.
