Description
Technical Field
The invention relates to the field of ventilation, in particular to ventilation of residential sites. Designed specifically for forced supply of purified and possibly heated air from the street to the room.
Background
There is known an air supply and ventilation device (patent document RU2194222, published 12.10.2002) comprising: the device comprises an insulated shell, an adjustable ventilation grid, a protective outer wall grid, a porous insulating material positioned in the shell, and a baffle plate which is in the form of a wind-proof valve formed by a plate hinged in the upper shell or hinged in the side wall of the shell and can move in an equiangular or unequal angle relative to a fixed axis.
The disadvantage of this device is that the direction of flow of the air entering the room cannot be changed, as a result of which the room cannot be supplied with air efficiently.
Known air supply and ventilation devices, provided on the external walls of buildings (patent document RU130050, published 2013, month 07, 10). The apparatus comprises: a housing, an upper surface and a lower surface of which are made of a sealing material; adjustable ventilation grille, facade protection grille and porous insulating layer. At least two laminar partitions made of airtight material are fixed, respectively at an angle with respect to the upper and lower surfaces of the casing, are mounted parallel and opposite to each other and form between them a passage for the passage of air.
The disadvantage of this device is the insufficient filtration (removal of aerosols) of the air coming from the street with porous insulating material.
A known supply and purification ventilation unit (disclosed in patent document RU 176378Ul 2018, 01 month 17) comprises: a fan unit in the housing, a filter, a flow control valve, a control unit electrically connected to the flow control valve, an air outlet grill connecting the housing to the air outlet port at an opening of the air passage, the fan unit being equipped with a fan, wherein an intake grill is additionally provided in the housing and a carbon dioxide sensor is provided thereon, the intake grill being formed on different planes, connecting the intake grill housing with the opening of the passage, the control unit being electrically connected to the fan, and including a control board connected to the carbon dioxide sensor.
A disadvantage of this device is that condensate can form on the outlet grille, thus reducing the efficiency of supplying purified air to the room.
A known patent document RU 80923Ul, published 2.2009, 27 discloses an air supply and ventilation device (prototype) comprising: a fresh air supply channel located on a wall, an electric heater with an overheating protection element, an internal insulated casing forming a channel for the recirculation of indoor air, a filter, a fan and valves installed therein. The device is also equipped with an air temperature sensor at the room outlet, and an automatic control system with an electric drive that controls the valve status according to the current temperature value of the air supplied to the room.
This apparatus has a disadvantage in that the air supply is insufficient due to the internal position of the electric heater and the filter in the ventilation duct, which in turn increases the air resistance and makes it difficult to supply the air through the ventilation duct. In this case, the direct entry of air from the ventilation duct through the central opening in the housing may cause various eddy currents and curved laminar flows inside the device, which may affect the supply efficiency of the air. In addition to the location of the fan at the top of the housing, this can also negatively affect the efficiency of the fan if the top and bottom of the cabinet have openings to communicate between the interior of the equipment housing and the interior of the room. Since the fan sucks air from the ventilation duct and enters the room through the bottom opening of the housing, air can be supplied to the room.

Detailed Description
The intake grill 1 includes: a hollow cylindrical housing 19, an edge ring 20 formed at the edge of the housing 19, inclined sheets 21 located inside the housing, and at least two inclined sheets 22 having an extension in the lower portion of the hollow cylindrical housing 19, a first inclined sheet 23 having a shorter extension in the bottom of the hollow cylindrical housing 19, and a separator 24 having a vertical plate type in the vertical direction provided in the center of the inclined sheets 21 inside the housing 19. Inside the housing 19, in the centre of the first inclined sheet 21, starting from the bottom and the top, a seat 28 for fixing elements is provided. The preferred inlet grille 1 has an inlet opening of 96 mm diameter and a large number (9) of inclined lamellae 21 additionally reduces the effective area of the inlet opening. In addition, when the diameter of the air inlet is 126 mm, the number of the inclined thin plates 21 is 7. The preferred number of inclined sheets 22 with extensions is 4, the first sheet 23, which is arranged at the bottom of the hollow cylindrical housing 19, with shorter extensions. The air intake grille 1 may be made of a composite material of metal and plastic.
The inlet grille of the hollow-cylindrical housing 19 has an edge ring 20 at the outer edge, which ensures that the shape of the housing 19 of the inlet grille 1 is maintained and that the housing 19 can be fitted tightly into the inlet air channel 2, as well as that the housing 19 of the inlet grille is maintained in shape and provides a stable area cross section, ensuring that air is supplied to the interior of the housing 19 in windy and inclement weather conditions, without the inlet grille and the air channel 2 being deformed and bent by the housing 19.
The provision of at least two inclined sheets 22 with extensions in the lower part of the hollow-cylindrical housing, which is provided with inclined sheets 21 extending from the outer edge towards the interior of the housing, ensures the uniformity of the laminar flow after entering the housing 19 through the air intake grille, and eliminates the swirling and bending of the air flow in the lower region, which has a positive effect on the efficiency of the air supply.
The housing 19 of the air inlet grille 1 is tightly connected to the air channel 2, and a first inclined sheet 23 is provided at the lower part of the hollow cylindrical housing 19, which inclined sheet 23 acts as a support, which has a positive effect on a reliable fixation and air transport efficiency in bad weather and strong winds.
In the intake grill 1 inside the housing 19, a base 28 for fixing members is provided at the center position of the inclined thin plate 21 at the lower and top portions of the intake grill 1, so that the housing 19 of the intake grill 1 can be more reliably fixed to the air passage 2 against bad weather and strong wind while being easily installed.
For a housing 19 of a large-diameter air inlet grille 1, it is possible to provide the separator 24 in the form of a vertical plate in the center of the inclined lamellae 21 of the housing 19, the particular separator between the inclined lamellae 21 having a positive influence on the efficiency of the air supply in bad weather and strong winds.
The forced air supply device 6 includes: a body made of a decorative panel 7 and a carrier plate 8 with a base 9, a body 10 and a cover 11 of a scroll 26 adjacent to the base 9, while channels are formed in the interior of the cover 11 and the body 10 of the scroll, the channel depth 31 and the channel cross-sectional width 12 increasing gradually in the direction of the air movement, forming an asymmetric diffuser. In an asymmetric diffuser of the channel, the area of smooth diffusion of the gas flow is gradually enlarged, forming a diffuser with a diffusion angle α, which varies between 30 and 60 degrees. In this case, the optimum angle α is chosen to be equal to 45 degrees, and all the angles on the surface of the scroll are rounded in order to avoid the formation of vortices. Also included are a radial fan 13, a damper 14 and an electronic unit 15 fixed within the scroll 26, and the body 10 and base 9 of the scroll are all provided with a central bore coaxial with one another.
In a variant embodiment, the forced air supply means 6 may have an overall size of 260 × 260 × 130 mm, although it is possible to adjust the above-mentioned overall size individually. The weight of the forced air supply device 6 having the above-specified overall dimensions must not exceed 5 kg.
The coaxial central holes formed in the base 9 (carrier plate 8) and the body 10 of the scroll 26 ensure a smooth flow of air from the air passage 2 into the inner space of the scroll 26, i.e. the passage of the scroll. The channel depth 31 and the channel cross-sectional width 12 gradually increase in the direction of air movement in the channel, forming an asymmetric diffuser so that no turbulence occurs, thus providing minimum air resistance and improving air supply efficiency.
The radial fans 13 inside the scroll 26 and the internal channels formed by the body 10 and the cover 11 have channel depths 31 and channel cross-sectional widths 12 that gradually increase with the direction of air movement. The asymmetric diffuser formed within scroll member 26 provides a smooth air circulation flow, i.e., the channel depth 31 and channel width 12 in the channel gradually increase in the direction of air movement, forming an asymmetric diffuser, thereby allowing the free flow of air from air channel 2 through scroll member 26 into the vortex within the channel, which increases the efficiency of the air supply. Furthermore, since the channel depth 31 and the channel cross-sectional width 12 are gradually increased in the direction of air movement due to the air entering the channel from the central hole of the scroll body, thereby forming an asymmetric diffuser, since a part of the air in the scroll 26 enters the room and the rest of the air passes through the channel having the channel depth 31 again, a circular movement can occur in the scroll 26, thereby accelerating the air flow effect. And by forming an asymmetric diffuser the channel cross-sectional width 12 gradually increases in the direction of the air movement, creating an air flow in the direction in which air is gradually sucked out of the air channel 2 and creating a circular movement. An air flow is generated within scroll member 26 which tends to have laminar flow characteristics which ensure a rapid and orderly flow of air while increasing the efficiency of the supply. The circulating air flow also advantageously affects the efficiency of the air supply when the damper 14 is open, since no eddies and stagnant zones are created in the area of the damper 14, which adversely affects the air flow.
The design of scroll 26 avoids the formation of turbulence and unstable flow and at the same time ensures uniformity of air flow along the entire length of the air passage, the impeller of radial fan 13, and the passage formed by the wall of scroll 26, the depth 31 of the passage formed in scroll 26 and the width 12 of the passage cross-section gradually increase in the direction of air movement, forming an asymmetric diffuser, while at the same time, a smooth rounding process is performed on the inner surface of scroll 26.
By providing the damper 14 with a heat insulating material, condensed water can be prevented from being formed on the surface of the damper 14, so that the efficiency of supplying air into the room can be improved, and the reliability of the operation can be improved. This arrangement, and particularly where the ambient temperature is low, reduces wear and damage to the arrangement due to the temperature drop across the face of the damper 14.
The temperature sensor 25 is provided at the outlet of the scroll 26 of the forced air supply device 6, and the supply of the outside air into the room can be optimally adjusted, so that the efficiency of the air supply can be improved. The sensor 25 sends a signal in real time to the electronic unit 15, while also providing instructions from the electronic unit 15 in real time to the radial fan 13 and the damper 14, so that the temperature state of the supply air set by the user can be maintained.
The heater 16 is arranged on the base 9 of the carrier plate 8 and provides heating according to a set temperature condition while maintaining a minimum aerodynamic resistance in the passage of the compact air supply ventilation system, and the base 9 is structured and positioned to provide a high efficiency of air supply by its own support according to the minimum aerodynamic resistance condition in the passage of the system. Meanwhile, since the temperature setting range of the input air is conformed, by knowing the characteristics of the air flow, the operation modes of the radial fan 13 and the damper 14 can be controlled with respect to the characteristics of the air flow according to the program set in the electronic device.
An insert adapter is provided on the base 9 of the carrier plate 8, the insert adapter 17 for the forced air supply device 6 fulfilling the structure required to hold the inlet of the scroll 26 on the forced air supply device 6, ensuring a minimum aerodynamic resistance and thus improving the efficiency of the air supply.
The asymmetric diffuser opening angle of the forced air supply means, which is 30-60 degrees, ensures a smooth flow of air flow from the air channel 2 into the channel, wherein the channel depth 31 and the channel cross-sectional width 12 gradually increase in the air movement direction, forming an asymmetric diffuser ensuring air flow which ensures a non-swirling movement of the air and thus improves the efficiency of the air supply by reducing the aerodynamic resistance in the channel through which the air flow flows.
In one embodiment, there is provided a compact air supply ventilation system comprising: an intake grill 1, the intake grill 1 including: a hollow cylindrical housing 19 is provided with an edge ring 20 from its outer edge, and an inclined web 21 extends from the outer edge towards the interior of the housing. In the lower part of the hollow cylindrical housing there are at least two inclined sheets 22, which sheets 22 have an extension towards the air channel 2, the air channel 2 being connected to a forced air supply 6, and inside the air channel 2 there is provided a corrugated cone filter 5, which corrugated cone filter 5 is mounted by means of an elastic ring 3 and a centering ring 4.
In another embodiment, a compact supplied air ventilation system includes: air intake grille 1, air passageway 2, forced air supply device 6 includes: the housing formed by the decorative panel 7 and the carrier plate 8 with the base 9 comprises the body 10 of the scroll 26 adjacent to the base 9 and the cover 11, while inside the body 10 of the scroll and the cover 11 there is a channel with a channel depth 31 and a channel cross-sectional width 12 increasing gradually in the direction of the air movement, forming an asymmetric diffuser, the corrugated cone filter 5 being mounted in the air channel 2 by means of the elastic ring 3 and the centering ring 4.
The corrugated conical filter 5 was pleated with filter material to form 3 to 8 mm corrugation spaces 30 (fig. 8), and the filter 5 had an outer diameter of 67 mm at one end. As the diameter of the filter 5 increases, the cross-sectional area of the channels decreases and the pressure drop across the filter increases (solid line in fig. 3), while the pressure drop varies as the corrugation pitch 30 decreases (dashed line in fig. 3) as the filter material approaches the centering ring 4. The centering ring 4 and the elastic ring 3 are made of plastic.
The pressure drop over the filter 5 is minimal when the centering ring 4 (central guide element) has a diameter of 67 mm.
The compact air supply and ventilation system operates on the principle that, due to the operation of the radial fan 13, air from the street is drawn into the air passage 2, passing through the air intake grill 1 to prevent foreign matter from entering the system and the air passage 2. At the same time, the air flow flows flush and orderly over the inclined sheets 21 through the intake grill 1. Furthermore, the ordered air flow flows through the air channels 2, floating first on the smaller diameter end of the corrugated conical filter 5 of the centering ring 4. The ordered gas stream is then gradually filtered through the filter material of the corrugated conical filter 5. Due to the conical shape of the corrugated conical filter 5 the cleaning process takes place evenly without swirling and due to the provision of the elastic ring 3 unpurified air cannot penetrate behind the corrugated conical filter 5 either, which elastic ring 3 separates and seals the area of cleaned air and contaminated air. The cleaned air flow then reaches the end of the air channel 2 and flows into the area of the base 9 on the carrier plate 8 of the forced air supply 6, where the heater 16 and the adapter insert 17 are arranged, on which heater 16 and adapter insert 17 the cleaned air flow passes after which the cleaned air flow enters the scroll 26, i.e. the blades and the channel of the radial fan 13, the channel depth 31 and the channel cross-sectional width 12 of which gradually increase in the direction of the air movement, forming an asymmetric diffuser for the scroll 26. Furthermore, the air flow passes through the passages of the scroll and finally through the outlet grill 27, after which the air is discharged, and because of the operation of the forced air supply 6, the air flow can freely be discharged and will enter the existing air circulation in the room.
The corrugated conical filter 5 is a filter material provided with a corrugated spacing 30 of 3 to 8 mm. With such a parameter setting, an optimum throughput of the filtration of the corrugated conical filter 5 can be ensured with a minimum of aerodynamic resistance, which has a positive effect on the air supply efficiency.
The corrugated conical filter 5 placed in the air channel 2 ensures a minimum air resistance on the surface of the filter 5 and in the air channel 2. The conventional mesh or bag filter blocks the air passage 2 and has a high air resistance, and the corrugated cone filter 5 significantly reduces the resistance to air flow because: the corrugated conical filter does not clog up at a certain position in the cavity of the air channel 2, but only limitedly (in cross-section) in a part of the air channel 2. Since the corrugated conical filter 5 gradually closes the cavity of the air passage 2 in the lengthwise direction, and since the air is filtered in the corrugations of the filter 5, and the air flow flowing in the air passage 2 is gradually, smoothly and turbulently filtered on the corrugated conical filter 5 and then flows into the scroll member 26 of the forced air-supply device 6, an effective air supply is provided. In this case, the corrugated conical filter 5 increases the area of the filtering surface.
The forced air supply 6 of the compact air supply ventilation system can be rotated with respect to the axis of the air passage so that the output air flow can be directed in any direction, and the optimum circulating air can achieve a complicated air circulation in a room having a complicated geometry or in consideration of the existing air flow in the room, thereby improving the efficiency of supplying air to the room.
The technical solution provided by the present invention thus improves the air supply efficiency by reducing the aerodynamic resistance inside the air channel and ensuring a smooth and without significant turbulence of the air flow entering from the street through the air intake grille through the air channel. The channel depth and the channel cross-sectional width of the air supply means further gradually increase in the flow direction of the air, and an asymmetric diffuser is formed inside.
