Definitions
- the present invention relates to a ventilator for a building, and in particular although not exclusively, to a passive and passive assisted ventilation stack.
- Ventiler systems provide a means of regulating the internal temperature of a building where occupants, equipment and solar heat contribute to the internal temperature of the building and if unregulated would lead to overheating.
- Mechanical ventilation is the most commonly used form as it offers on demand and controllable delivery rates.
- mechanical ventilation include convention air conditioning that utilises refrigeration and a fan to drive airflow circulation around the system and the interior of the building.
- Natural ventilation relies on the external wind conditions to deliver the required fresh air supply.
- a natural ventilation stack device sits at the top of the building or room and acts as both an inlet and extract. As warm air rises and exits the room via the stack, a negative pressure is created in the room which acts to draw-in an external fresh air supply. The flow of air through the device is further assisted by the windward and leeward pressures exerted on it by the external wind speed. The rate at which the flow is delivered to the receiving room is controlled by mechanical dampers and a static ceiling diffuser.
- Natural ventilation systems may be further categorised into two groups, namely passive and active.
- a passive stack applies no mechanical force to induce the flow through the device.
- An active stack utilises a mechanical force to create or direct the flow through the system. The active stack ensures the required air supply rates will be achieved. However, this stack does not offer the level of energy consumption savings of the passive system.
- GB 2432207 discloses an active stack ventilation arrangement that utilises a fan positioned at the bottom of the ventilator to draw air into the building interior.
- the present invention provides a natural ventilator configured to supply fresh air into the interior of a building and importantly to allow stale air to exit the building interior without requiring mechanical or electrically driven components.
- a hybrid device which offers the mechanical assistance of an active stack without compromising the energy consumption level of a passive stack is provided and is referred to as a passive-assisted stack.
- This hybrid device utilises a fan positioned within the natural ventilator, the fan being operable only when required to assist the flow of air between the building exterior and interior via the ventilator.
- a building ventilator comprising:
- the inventors have discovered that by altering the angle of inclination of the individual blades of the louver, the velocity and pressure performance and importantly the rate of air flow into and out of the building interior is improved and optimised with regard to the circulation of clean air from the building's exterior to its interior.
- each blade is inclined relative to the horizontal at an angle in the range 32 to 38°. More preferably, this angle of inclination is within the range 34 to 36° and optimally is 35°.
- the ventilator comprises internal walls extending in the longitudinal direction between the external and internal facing ends of the frame to partition the air flow duct and to guide air flow through the ventilator.
- the ventilator frame and louver may comprise any shape and configuration to suit the requirements of the building.
- the cross sectional profile, in the horizontal plane, of the frame and louver sections of the ventilator may define a circle, oval, square or rectangle.
- the frame is cuboid in particular rectangular or square cuboid comprising four walls being open at a top and adj acent bottom face.
- the frame is arranged in the ventilator with the top face being external facing and the bottom face being interior facing.
- the ventilator blades are joined at each end to adjacent blades, in the same plane, to define the edges of a rectangle and/or square.
- This quad blade structure may be formed as a modular arrangement or as a unitary blade arrangement in which the four blades are inclined upwardly towards a central plane within the square or rectangle.
- the quad blade arrangement may be mounted at the exterior facing top face of the cuboidal frame above its four walls to define a louver having four sides comprising a plurality of blades arranged on top of one another extending over each face.
- the ventilator may comprise a cover member to sit above the uppermost blade and block the exterior facing end of the duct defined by the upper region of the louver.
- each blade may comprise a flange positioned at the leading and trailing edge and projecting transverse to the blade. With the blades aligned in position to be inclined at an angle 32 to 38° relative to a horizontal plane, each flange may extend substantially vertically.
- the ventilator comprises a stack of four to six blades arranged on top of one another, the blades comprising a single blade or quadrant of blades having four sides in the same plane.
- the ventilator comprises four blades and in particular four quadrant blade sets.
- the ventilator may comprise any number of vent blades to suit the requirements of the building with regard to fresh air delivery rates and wind noise.
- the distance in the vertical direction between adjacent blades in the louver stack, at the their respective leading edge regions is in the range 25 to 35 mm.
- the vertical distance between adjacent blades is 27 to 33 mm and more preferably, the vertical distance between adjacent blades is 30 mm.
- the ventilator comprises a fan mounted within the louver region of the device defined by the stack of blades substantially between a lowermost blade and an uppermost blade in the vertical direction.
- the fan is mounted within the louver region of the device towards the blade positioned furthest from the external facing end of the frame in the vertical direction. More preferably, the fan is mounted within the louver region of the device substantially in the same horizontal plane as the blade positioned furthest from the external facing end of the frame in the vertical direction. The fan may be mounted centrally within the louver region of the device in the horizontal plane.
- the ventilator is devoid of internal partition walls within the duct extending in the vertical direction between the external and internal facing ends.
- the ventilator comprises control means to provide manual and/or automatic control of the fan.
- the ventilator may also comprise an electric motor configured to drive the fan with the control means coupled to the electric motor.
- the control means may be coupled to a suitable wind gauge and is operative in response to the wind speed detected by the wind gauge.
- a natural ventilator provided by the inventors is optimised to supply fresh air into the interior of a building whilst minimising energy consumption.
- the present invention provides both a passive and a passive-active system configured to maintain airflow rates into the building interior in the event of reduced wind speed at the exterior of the building.

- the louver blades 202 extend from the external facing open end 305 of frame 200 positioned external 103 to the building interior 104. Accordingly, frame 200 and louver blades 202 define an internal air flow passageway extending vertically through the ventilator comprising internal louver duct 300 positioned directly above duct 302 defined by frame 200.
- one or a plurality of internal partition walls 301 may be positioned within the frame duct 302 and/or louver duct 300 to guide the airflow through the ventilator and into the building interior 104.

- Each blade region is bordered by upper and lower flanges 401, 402 as illustrated in figure 4a .
- Each of the four blade regions 403, 406, 407, 408 and the associated flanges 401, 402 are connected at their respective ends to form a square or rectangular quadrant, with each side represented by each of the four inclined blade regions.
- each inclined blade region 400 is inclined, relative to a horizontal plane 417 by an angle ⁇ .
- ⁇ is in the region of 30 to 40°, 32 to 38° and 34 to 36° and optimally substantially 35°.
- each louver blade 202 is arranged on top of one another in a vertical direction above frame 200 to form the louver.
- each blade 200 is separated from a neighbouring blade, in a vertical direction by distance d.
- Distance d is defined as the distance between the lowermost edge 409 of flange 402 of an upper blade A and the upper edge 412 of flange 402 of a neighbouring lower blade B.
- Distance d corresponds to the available space, in the vertical direction through which air may flow from exterior 103 into the louver interior 300.
- distance d corresponds to the distance between the lowermost surfaces 413 of an upper blade to the uppermost surface 414 of a lower blade.
- each blade 202 comprises a leading edge 416 being external facing and a trailing edge 415 arranged internally to define louver duct 300.
- each blade comprises four leading edges and four trailing edges.

- the present invention is configured to utilise any number of louver blades positioned intermediate 502 between upper blade 500 and lower blade 501.
- Ventilator 102 comprises four blades and in particular four blade quadrants illustrated in figure 4b stacked on top of one another directly above frame 200.
- the present invention also relates to a hybrid natural and mechanical ventilator referred to a passive-assisted natural ventilator.
- the hybrid ventilator utilises a low energy fan driven by a low voltage battery (not shown).
- the battery may be charged by a solar panel (not shown) positioned at/or on top of cover 204.
- the fan or battery may be coupled to a mains supply.
- Figure 6 illustrates a passive-assisted ventilator arrangement comprising a fan 600 having fan blades 605, the fan and blades being mounted internally within ventilator 102.
- Frame 200 may be divided into three regions in the vertical direction, an uppermost region 602 positioned directly below lowermost fan blade 501; a lowermost region 604 and an intermediate region 603 positioned between upper and lower regions 602, 604 respectively, in the vertical direction.
- control dampers (not shown) may be housed within lowermost frame region 604 to provide control of the airflow velocity and direction through the ventilator and into the building interior 104.
- Figure 7 illustrates the various regions through the ventilator for which statistical airflow behaviour was investigated.
- regions 700 to 704 representing pressure and velocity in the horizontal plane at various regions spaced apart in a vertical direction through the ventilator.
- the pressure and velocity was also determined in the vertical plane 705 extending through the louver duct 300 and frame duct 302 referring to figure 3 .
- Plane 700 is positioned at the top of the vent in close proximity to the uppermost fan blade 500.
- Plane 701 is positioned at the top of the frame in close proximity to its uppermost open face 305.
- Plane 701 is positioned at the top of a vertex build up in the ventilator referred to as the trailing edge stall with plane 702 positioned at the bottom of this vertex.
- Planes 703 and 704 are positioned at the either side of the dampener region 604 in a vertical direction with plane 704 positioned in close proximity to the bottom open face 304 of frame 200.
- the results of the pressure and velocity investigation, illustrated in figures 8 to 11 correspond to the various regions through the ventilator in which data was analysed as detailed in figure 7 .
- the present invention is designed to provide optimum 'comfort levels' within building interior 104. This is achieved via an investigation into the variation of air velocity, pressure and density through various regions of the ventilator in response to variation of the angle ⁇ , distance d and position of fan 600 in a vertical direction through ventilator 102.
- Figures 8 to 11 detail the effects of blade angle variation; figures 12 to 15 illustrate the effect of fan position within the ventilator and figure 16 illustrates the effects of louver spacing.
- the effect of varying the blade angle on the pressure and velocity through the ventilator was determined to achieve the optimum blade angle for maximum comfort levels and in particular fresh air delivery rates into the building interior 104.
- air pressure data 800 was obtained at region 703; air pressure data 801 was obtained at region 704; air pressure data 802 corresponds to the pressure drop across the dampener region 604; air pressure data 803 corresponds to pressures at region 700.
- air velocity data 900 was obtained at region 703; air velocity data 901 was obtained at region 704; air velocity data 902 corresponds to the 'comfort level' representing the average airflow movement velocity within room interior 104; air velocity data 903 was obtained at region 700.
- data 1000 correspond to the air pressure verses blade angle in the vertical plane 705 with data 1001 corresponding to the air velocity in the vertical plane 705.
- Figure 11 illustrates the overall performance of the ventilator with data 1001 corresponding to the 'comfort level' and data 1000 and 1001 corresponding to that of figures 8 and 9 .
- Figure 10 illustrates the average velocity and pressure across the vent against the attack angle of the blade. As the pressure inside the ventilator decreases the velocity will increase, as effectively any flow restriction is reduced. From figure 10 it is evident that at the points of intersection, the flow and pressure is at the optimum for the ventilator's performance. The two points of intersection of data 1000 and 1001 are 28° and 35° respectively.
- Figure 11 illustrates the scaled comfort level, pressure and velocity against the blade angle.
- the comfort level is scaled by a factor of ten in order for it to fit the velocity and pressure profiles for comparison, this does not affect the results in any way.
- the plots show clearly that at the second point of intersection, 35°, the comfort level within the occupied area is at its peak.
- Figure 12 illustrates the ventilator 102 with fan 600 positioned at an upper region of the ventilator in close proximity to uppermost fan blades 500.
- Fan 600 is operative to assist the airflow current in a downward direction 1200 though the internal duct of the ventilator 300, 302.
- the airflow stream 1201 continues out of the bottom face 304 and into building interior 104 and then circulates 1202 through interior 104 and exits this interior 1203 as the airflow current circulates between exterior 103 and interior 104.
- stale air 1203 from interior 104 is capable of exiting the ventilator via flow path 1205 between louver blades 202.
- Figure 13 illustrates the ventilator of figure 12 with fan 600 positioned at a more central region corresponding to region 602 illustrated in figure 6 .
- fan 600 creates a strong airflow stream 1300 and 1301 in a substantially vertically direction into interior 104.
- Stale air 1302 re-enters the ventilator via open face 304.
- this stale air 1302 is then directed 1303 into the airflow suction path created by fan 600 to be reintroduced into interior 104 via airflow path 1300. This diversion of the airflow path 1303 is caused by the airflow currents created within the louver region due to this mid fan position.
- Figures 14 illustrates a similar arrangement to figures 12 and 13 albeit with fan 600 positioned at a lowermost part of ventilator 102 corresponding to region 604 of figure 6 .
- a strong airflow current is created 1400, 1401 in a vertical direction within interior 104.
- Stale air 1402 then re-enters the ventilator via open face 304 and is redirected at 1405 into the suction airflow path created by fan 600.
- stale air 1303, 1405 is presented from escaping from the ventilator 1205 (referring to figure 12 ) due to the turbulence created within the louver region 201 by the relative fan position.
- the fan position also has an affect upon the airflow at environment 103 into louver duct 300.
- Referring to figure 12 with fan 600 at an uppermost position, clean air is capable of flowing into the ventilator 1204 over the entire height of the blade stack.
- the fresh air supply 1304, 1403 into the ventilator is perturbed by the eddy currents created within ventilated duct 300.
- fan 600 positioned at its lowest most orientation of figure 14 the fresh air supply is prevented from entering the ventilator 1404 due to the turbulence within louver duct 300.
- Figure 15 illustrates the total fresh air delivery rates supplied by ventilator 102 for the three fan positions of figures 12, 13 and 14 .
- Data 1500, 1501 and 1502 correspond to fan 600 positioned at the top ( figure 12 ), middle ( figure 13 ) and bottom ( figure 14 ), of ventilator 102, respectively.
- the British Standard (BS) minimum fresh air delivery rates are specified as 0.8 L/sec per m 2 and 5 L/sec per occupant.
- the occupancy level for this investigation was 20 occupants which is the recommended level for a small classroom. According to the present investigation, when the external wind velocity is 1m/s ventilator 102 does not meet the criteria for the amount of fresh air per occupants and therefore the passive ventilator 102 requires assistance.
- the fan in the top position of figure 12 creates the smallest increase in fresh air supply from 4.5 to 18.5 L/sec per occupant at a fan pressure of 20 Pa.
- the flow visualisation of these results shows that the fan draws in fresh air whilst allowing the receiving room's exhaust air to exit via two channels 1205 either side of the fan.
- a low voltage fan would need to produce a minimum pressure of 20 Pa to achieve the BS required minimum ventilation rates.
- the fan should be located in the top position to ensure fresh air is drawn in at low external wind speeds (1 m/s) and delivered to the receiving room without restricting the exhaust air flow path.
- louver blade spacing By changing the external distance of separation between the closest regions of adjacent louver blades 202 (distance d) illustrated in figures 4c and 5 , the rate at which fresh air is delivered into the building interior is affected.
- the undesirable affects of increasing the louver blade spacing are twofold:
- FIG. 16 illustrates experimental results with data 1600 corresponding to the velocity of air through the ventilator, data 1602 corresponds to the pressure of air through the ventilator and data 1601 corresponds to the 'comfort level' being the air movement rate within the building interior 104.
- louver spacing (d) of 30 mm.
- reducing the louver spacing has therefore been found to match the observed air movement rate within interior 104 in addition to reducing breakthrough noise and the likelihood of rain ingress into ventilator 102.
