The specific embodiment
Fig. 2 shows ventilation (ventilation) system 50 that is provided with along the joint 52 (for example, angle, turning) between back wall 28 and the ceiling 26.This system comprises one or more ventilating openings.Fig. 3 shows a pair of exemplary left ventilating opening 54A and right ventilating opening 54B, near a left side and the right-hand member of back wall, on the left side and right- hand member wall 56A and 56B of inner space.Ventilating opening can directly or through pipeline 60 lead to building outside (Fig. 2).As further going through, in first mode of operation, system can provide the whirlpool of staying that air is transferred out ventilating opening at least.Example system produces a pair of eddy current 62A of the longitudinal direction have identical angle loop direction and outwards to disperse and 62B (Fig. 4) mirror image of the vertical plane between the ventilating opening (for example, median plane) 500 (for example, about).Eddy current 62A and 62B transfer out air left ventilating opening 54A and right ventilating opening 54B respectively.
Deflector apron 70 (Fig. 2) by system 50 produces/catches exemplary eddy current.Exemplary deflector apron 70 cooperates to limit capture space with the top of back wall and the rear section of ceiling, and promptly the minor air cell 72.
In first mode of operation, ventilating opening 54A and 54B be the exemplary outlet of 72 formation from the minor air cell.Equally at least, there is an inlet.Exemplary inlet 74 is single inlet, extends on the length of back wall.The exemplary baffle plate 70 vertical extensions of level then.Exemplary shutter configuration has the L-tee section.The exemplary shank 76 of L roughly vertically extends, and exemplary foot 78 approximate horizontal of L are extended.Exemplary inlet is between the front surface of the foot end 80 of baffle plate and back wall.
In first mode of operation, when air-flow 46 along the length direction of back wall upwards by the time, air-flow enters minor air cell 72 through inlet 74.Minor air cell 72 can have the combination of two effects.At first, the restriction of chamber formation is towards exporting laterally steering current.In exemplary symmetric construction, this relates to this air-flow with respect to median plane 500 with mirror image effectively laterally separately.In addition, the momentum of this air-flow is diverted (, as shown in Figure 2 counterclockwise) when running into ceiling (chamber roof).When this air-flow was run into shank 76, foot 78 and back wall 28 subsequently subsequently, this turned to continuation.Fig. 3 shows relevant to the cold air recirculation 86 at Zhongting center and near the opposite local circulation 88 the joint of front wall and ceiling.
In some cases, may expect that warm air recirculation is by inner space 22.For example, in the winter time, this heating can advantageously replace or additional active heating system.Therefore, this system can be configured to change between first pattern and second pattern, wherein in first pattern, and air of promotion in the whirlpool and hot driving, in second pattern, the effect of staying the whirlpool or staying the whirlpool is reduced in some way.Pattern changes can be alternately or additionally relevant with opening/closing ventilating opening 54A and 54B.Fig. 6 shows a kind of structure, and wherein the shank 76 of L-cross section baffle plate is hinged to open the minor air cell and to allow air-flow along its recirculation flow path process.Exemplary is hinged for folding (for example, being rotated down) in foot 78.But the hinged of other also is fine.
Hinged (for example, shank 76) can be manual or driven by actuator 90 (for example, motor, pneumatic actuator, hydraulic actuator or the like).Can import the control system 100 (Fig. 1) (for example, it can be incorporated into the main HVAC control system of building) of one or more temperature sensor 102A-C of inner space diverse location (for example) through response sensor and control actuator.In the first exemplary pattern (eddy current air vent mode), be passive work (can be optional) basically by the ventilating opening discharged air.But alternately, can come supplemental air flow by for example wind-force, by means of one or more also can be by the electric fan 104A and the 104B of control system 100 control.Exemplary fan 104A and 104B are the air-conditioning unit (AHUs) of traditional (for example, existing) HVAC system of building, and wherein the continuous operation in all air vent modes of HVAC system exchanges with the fresh air that expectation is provided.
In an example, this pattern can be changed seasonally: in summer is eddy current first pattern of ventilating; And be second pattern in other season.Also can use a day moment: be the eddy current air vent mode in the significant insolation period; Other situation is next to be second pattern.As mentioned above, according to sensor and fixed operation also is fine.
Can further divide first and second patterns.For example, second pattern can be divided into: a kind of no eddy current air vent mode with fan promotion; And the another kind of pattern that does not have ventilation.
In exemplary enforcement, heat extraction is more than the heat extraction of (for example, the fan work parameter is a constant, but is not to do like this) under the no eddy current air vent mode of fan promotion in the eddy current air vent mode.Even with respect to mass flow, even and if the mass flow minimizing, the heat transmission that the heat transmission outside the inner space that is provided by system can provide separately above the ventilating opening (and AHUs) by similar setting.For example, only AHUs and ventilating opening, but all air mixtures of drain cooler comprise the more substantial bleed stream of taking out: along ceiling backward; With center from Zhongting.The eddy current air vent mode preferentially makes air discharged be taken out and draw along the back wall from the specific warm current that makes progress.This can allow the eddy current air vent mode with basic or do not have the eddy current pattern and compare, and can utilize air-flow identical or still less to take away more heat.
But, can be higher than basic or do not have an air-flow that discharges under the eddy current pattern at the air-flow (for example, mass flowrate) by ventilating opening discharging under the eddy current air vent mode.With respect to the ventilating opening of more equally distributed similar grid cross section (that is, extending the short ventilating opening of the whole lateral length of back wall), the use of being arranged to accept the discrete local ventilation mouth of eddy current discharging can have also that similar heat is transmitted and the air-flow increase.
Ventilating system can be set to the remodeling of existing building or be arranged in the design again of existing building construction.Alternately, can be in realization system in the blank design.Exemplary building space comprises the high elevator lobby/Zhongting of office building.
Can come the optimization system performance through the combination of experiment and simulation (for example, Fluid Mechanics Computation).Except shown in those, can introduce complicated more shape, part or the like.Exemplary designs/optimizing process can design the size of various parts at first based on the character of estimating.Improvement experiment or simulation is arranged after this.For example, in the basic structure of Fig. 2, baffle plate and chamber have feature height H cVentilating opening all has the feature height H that extends from ceiling downwards vInlet has depths of features D 1Can select or optimize D 1So that it is a bit larger tham the thermal-boundary-leyer thickness T of the wall of inlet 74 BExemplary D 1110-115% for thermal-boundary-leyer thickness.This allows air-flow to enter chamber but restriction is revealed.Favourable chamber depth D cBasically greater than D 1(for example, be approximately the T of thermal-boundary-leyer thickness BFour times).For the exemplary Zhongting height of 150m, exemplary ventilating opening height H vBe approximately one meter.Exemplary chamber height H cModerately greater than ventilating opening height (for example, about 1.4H v).Exemplary Zhongting height is greater than 20m, more particularly greater than 50m.
One or more embodiment of the present invention has been described.Yet, should be appreciated that and can carry out various modifications and without departing from the spirit and scope of the present invention.For example, the details of building design drawing, local climate and building direction can influence any specific enforcement.In addition, relate to the further any specific enforcement of influence of degree of the remodeling of blank design rather than existing building.Therefore, in the scope of other embodiment claim below.
