Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a central air conditioning system for large venues. Background Technology

[0002] Central air conditioning air conditioning unit refers to a major piece of equipment related to air handling in a central air conditioning system, also known as an air handling unit or air conditioning unit.

[0003] Both air handling units and air conditioning units draw air into the air handling unit through a centralized duct system for filtration, purification, dehumidification, cooling, or heating. The treated air is then delivered to the required locations through various ducts, with the aim of centrally controlling air quality and temperature.

[0004] Existing central air conditioning units are generally straight-in and straight-out type. However, when operating in areas with high air humidity, if the air inlet of the central air conditioning unit is aligned with the outdoor wind direction, outdoor air will enter the unit through the air inlet. When outdoor air enters the unit, it carries a large amount of moisture, increasing the burden on the filter and thus reducing the filtration effect of the outdoor air. Summary of the Invention

[0005] To overcome the drawback that a large amount of moisture can enter a central air conditioning unit when its air inlet is aligned with the outdoor wind direction, a central air conditioning unit for large venues is provided.

The component has a sliding connection with a first sliding frame that is circumferentially equidistantly distributed. The first sliding frame is rotatably engaged with the swing plate. A blower is installed inside the protective shell. An air outlet is provided on the side of the protective shell near the blower. The protective shell is equipped with a filter assembly for purifying outdoor air. The protective shell is equipped with an adjustment assembly for controlling the filter assembly. The protective shell is equipped with a cooling assembly for cooling outdoor air. Outdoor air is blocked by the swing plate to prevent outdoor air from directly entering the air inlet duct. The wind direction and speed measuring instrument, blower, filter assembly, adjustment assembly and cooling assembly are all electrically connected to the control terminal.

[0007] Furthermore, the lower inner wall of the fixed cylinder is truncated cone-shaped to guide the gas inside the fixed cylinder.

[0008] Furthermore, it also includes a windproof component, which is installed in the air inlet duct and is used to block outdoor wind from entering the air inlet duct. The windproof component includes a first rotating member, which is rotatably connected to the air inlet duct. An arc-shaped plate is fixedly connected to the first rotating member. A first drive motor is installed on the side of the air inlet duct near the first rotating member. The power output shaft of the first drive motor is fixedly connected to the first rotating member. The first drive motor is electrically connected to the control terminal.

[0009] Furthermore, a flow guide is fixed to one side of the outer periphery of the arc-shaped plate, which is used to divert the gas.

[0010] Furthermore, the filter assembly includes a second rotating member, which is rotatably connected to the protective shell. The second rotating member is located below the fixed cylinder. The second rotating member is fixedly connected to symmetrically distributed fixed rods. The second sliding frame is fixedly connected to symmetrically distributed first telescopic members. The first telescopic members on the side closer to the second rotating member are fixedly connected to it, and the first telescopic members on the side farther from the second rotating member are fixedly connected to the fixed rods. Adsorption members are fixedly connected between the symmetrically distributed first telescopic members. Each of the symmetrically distributed first telescopic members has a mutually fitting second telescopic member fixedly connected to its center side. Both the first and second telescopic members are provided with air outlets, and the air outlets of both the first and second telescopic members are inclined.

[0011] Furthermore, both the first and second telescopic components are made of thermally conductive material.

[0012] Furthermore, the cross-section of the adsorption element is folded to collect foreign objects and moisture from the outdoor air.

[0013] Furthermore, a collection box is fixedly connected to the protective shell, and the collection box is fixedly connected to and connected to a connecting pipe that is rotatably engaged with the second rotating component. A second drive motor is mounted on the protective shell via a bracket, and the power output shaft of the second drive motor is fixedly connected to the second rotating component via the bracket. The second drive motor is electrically connected to the control terminal.

[0014] Furthermore, the adjustment component includes a drive unit, which is fixedly connected to the protective shell. A fixed frame is fixedly connected to the telescopic end of the drive unit. The fixed frame is rotatably engaged with the second sliding frame. The drive unit is electrically connected to the control terminal.

The protective shell is fixedly connected to a second heat-conducting element, which is rotatably engaged with a first telescopic element on the side closer to the second rotating element. A connecting pipe is fixedly connected between the first and second heat-conducting elements, and coolant is stored in the connecting pipe. The protective shell is fixedly connected to a refrigeration element and a circulation element via a bracket. Both the refrigeration element and the circulation element are connected to the connecting pipe and are electrically connected to the control terminal.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention adjusts the exhaust angle according to the wind direction, so that the air intake of the air inlet duct maintains a certain angle with the wind direction, avoiding the outdoor wind from directly entering the air inlet duct, which would increase the burden on the filter components.

[0018] 2. The first and second telescopic components adsorb moisture and foreign matter in the outdoor air during rotation, thus purifying and filtering the outdoor air. The adsorption components adsorb water droplets and foreign matter on the first and second telescopic components, further enhancing the adsorption effect of the first and second telescopic components on foreign matter and water droplets during rotation.

Detailed Implementation

[0033] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0034] Example 1: A central air conditioning system for large venues, such as... Figures 1-5As shown, the device includes a support frame 101, a protective shell 102, a control terminal, and a wind direction and speed measuring instrument 103 for monitoring outdoor wind direction and speed. A fixed cylinder 104 is fixedly connected to and connected to the left side of the protective shell 102. The lower inner wall of the fixed cylinder 104 is frustum-shaped, allowing outdoor air to impact the frustum shape of the fixed cylinder 104, thus reducing the moisture content of the outdoor air. An air inlet duct 105 is fixedly connected to and connected to the upper side of the fixed cylinder 104. The air inlet duct 105 has circumferentially equidistantly distributed air inlets, and rotatably connected to equidistantly distributed swing plates 106 at the air inlets of the air inlet duct 105. The air inlet duct 105 is slidably connected... A sliding member 107 is provided, which consists of two frustum-shaped parts arranged vertically. When the outdoor wind blows, the sliding member 107 slides up and down, changing the swing angle of the swing plate 106, so that the swing plate 106 maintains a certain angle with the outdoor wind direction. A spring is provided between the sliding member 107 and the air inlet duct 105. The adjacent spring of the sliding member 107 drives it to return to its original position, so that the swing state of the swing plate 106 remains parallel to the ground. The sliding member 107 is slidably connected to a first sliding frame 108 that is circumferentially equidistant. The first sliding frame 108 rotates with the swing plate 106. A blower 109 is provided inside the protective shell 102, and an air outlet is provided on the side of the protective shell 102 near the blower 109.

[0035] like Figure 1 and Figure 3 As shown, the protective shell 102 is equipped with a filter assembly 3, which adsorbs moisture and foreign matter in the outdoor air to purify and filter the outdoor air. The protective shell 102 is equipped with an adjustment assembly 4, which is used to control the filter assembly 3. The protective shell 102 is equipped with a cooling assembly 5, which is used to cool the gas inside the protective shell 102. The wind direction and speed measuring instrument 103, the blower 109, the filter assembly 3, the adjustment assembly 4 and the cooling assembly 5 are all electrically connected to the control terminal.

[0036] When air conditioning is required, the blower 109 and cooling assembly 5 are started via the control terminal. The blower 109 draws outdoor air to the right. The outdoor air enters the fixed cylinder 104 through the air inlet of the air inlet duct 105. As the outdoor air flows through the fixed cylinder 104, it comes into contact with the frustum-shaped groove on the lower side of the fixed cylinder 104. The moisture contained in the outdoor air collides with the frustum-shaped groove in the fixed cylinder 104 and condenses on the frustum-shaped groove on the lower side of the fixed cylinder 104 to reduce some of the moisture contained in the outdoor air. The moisture condensed in the frustum-shaped groove on the lower side of the fixed cylinder 104 eventually forms water droplets that fall downwards. Guided by the frustum-shaped groove on the lower side of the fixed cylinder 104, the water droplets flow into the filter assembly 3, where the filter assembly 3 adsorbs the water droplets in the outdoor air.

[0037] Outdoor air flows downwards under the guidance of the fixed cylinder 104. Under the action of the blower 109 drawing air to the right, the outdoor air flows to the right. During the process of outdoor air flowing to the right, the filter assembly 3 adsorbs moisture and foreign matter in the outdoor air, thus purifying and filtering the outdoor air.

[0038] After being purified and filtered, the outdoor air comes into contact with the cooling component 5 as it flows to the right. The cooling component 5 cools down the outdoor air, thereby reducing its temperature. The cooled outdoor air is then sent into the room through the air outlet on the right side of the protective shell 102, at which point there is no wind outside.

[0039] When there is wind outdoors and the wind direction is upward, the outdoor wind direction will blow the slider 107 upward, causing the slider 107 and its parts to move upward. During the upward movement of the slider 107, the adjacent springs are gradually stretched. Under the action of the frustum shape at the bottom of the slider 107, the outdoor wind makes it easier to blow the slider 107 upward. During the upward movement of the slider 107, the first sliding frame 108 drives the adjacent swing plate 106 to swing upward. The circumferentially distributed first sliding frames 108 all slide inward and converge. During the upward swing of the swing plate 106, it gradually avoids direct contact with the wind direction, so that the air intake of the air inlet duct 105 maintains a certain angle with the wind direction.

[0040] When there is wind outdoors and the wind direction is downward, the sliding member 107 is blown downward by the direction of the outdoor wind, causing the sliding member 107 and its parts to move upward. During the upward movement of the sliding member 107, the adjacent springs are gradually compressed. Under the action of the frustum shape at the top of the sliding member 107, the outdoor wind makes it easier to blow the sliding member 107 downward. During the downward movement of the sliding member 107, the first sliding frame 108 drives the adjacent swing plate 106 to swing downward. The circumferentially distributed first sliding frames 108 all slide inward and converge. During the downward swing of the swing plate 106, it gradually avoids direct contact with the wind direction, so that the air intake of the air inlet duct 105 is kept at an angle to the wind direction.

[0041] When there is no wind outdoors, the sliding member 107 is driven to slide and reset by the spring adjacent to the sliding member 107. During the reset process, the sliding member 107 drives the adjacent swing plate 106 to reset through the first sliding frame 108. The state of the reset swing plate 106 is that the swing plate 106 remains parallel to the ground.

[0042] When air conditioning is no longer required, the blower 109 and cooling assembly 5 can be turned off via the control terminal.

[0043] Example 2: Based on Example 1, such as Figures 3-12As shown, the filter assembly 3 includes a second rotating member 301, which is rotatably connected to the protective shell 102. The second rotating member 301 is located below the fixed cylinder 104. The second rotating member 301 is fixedly connected to symmetrically distributed fixed rods 302. The second sliding frame 303 is fixedly connected to symmetrically distributed first telescopic members 304. The lower side of the lower first telescopic member 304 is fixedly connected to the second rotating member 301, and the upper side of the lower second rotating member 301 is fixedly connected to the lower side of the second sliding frame 303. The upper side of the first telescopic member 304 on one side is fixedly connected to the upper end of the fixed rod 302, and the lower side of the upper first telescopic member 304 is fixedly connected to the second sliding frame 303. An adsorption member 305 is fixedly connected between the two first telescopic members 304. The adsorption member 305 has a folded cross-section and is used to collect foreign objects and moisture from the outdoor air. A second telescopic member 306 that fits snugly is fixedly connected to the side of the two first telescopic members 304 near the center. Both the first telescopic members 304 and the second telescopic member 306 are made of metal and are used for... The system reduces the amount of moisture in the outdoor air by adsorbing moisture from the outdoor air through the first telescopic member 304 and the second telescopic member 306. It also reduces the amount of moisture contained within the first telescopic member 304 and the second telescopic member 306 by adsorption member 305. Both the first telescopic member 304 and the second telescopic member 306 are provided with air vents, and the air vents of the two vertically distributed members 304 and 306 face opposite sides. A collection box 3011 is fixedly connected to the protective shell 102. The collection box 3011 is fixedly connected to and connected to a connecting pipe 3012. The connecting pipe 3012 is connected to and rotatably engaged with the second rotating member 301. A second drive motor 3013 is mounted on the protective shell 102 via a bracket. The power output shaft of the second drive motor 3013 is fixedly connected to the second rotating member 301 via the bracket. The second drive motor 3013 is electrically connected to a control terminal.

[0044] like Figure 7 and Figure 8 As shown, the adjustment component 4 includes a drive member 401, which is fixed to the left side of the protective shell 102. The drive member 401 is an electric push rod. The telescopic end of the drive member 401 is fixed to a fixed frame 402 that rotates with the second sliding frame 303. The drive member 401 is electrically connected to the control terminal. Through the reciprocating movement of the second sliding frame 303, the first telescopic member 304 and the second telescopic member 306 on the upper and lower sides squeeze the adsorption member 305, thereby reducing the content of water droplets and foreign objects in the adsorption member 305.

[0045] like Figure 3 and Figure 13As shown, the cooling assembly 5 includes a first heat-conducting element 501, which is fixedly connected to the protective shell 102. The first heat-conducting element 501 is rotatably engaged with the upper first telescopic member 304. A second heat-conducting element 502 is fixedly connected to the protective shell 102, which is rotatably engaged with the lower first telescopic member 304. A connecting pipe 503 is fixedly connected between the first heat-conducting element 501 and the second heat-conducting element 502. Coolant is stored in the connecting pipe 503. A cooling component 504 and a circulation component 505 are fixedly connected to the protective shell 102 via a bracket. The cooling component 504 circulates coolant through the circulation component 505. The coolant in the connecting pipe 503 is cooled to the required operating temperature. Both the cooling component 504 and the circulation component 505 are connected to the connecting pipe 503. The connecting pipe 503 cools the first heat-conducting component 501 and the second heat-conducting component 502, so that when the outdoor air flows through the first heat-conducting component 501 and the second heat-conducting component 502, the moisture in the outdoor air is adsorbed by the first heat-conducting component 501 and the second heat-conducting component 502, thereby reducing the moisture contained in the outdoor air. Both the cooling component 504 and the circulation component 505 are electrically connected to the control terminal.

[0046] When air conditioning is required, the cooling component 504 and the circulation component 505 are activated via the control terminal. The cooling component 504 cools the coolant in the connecting pipe 503. During the cooling process, the circulation component 505 circulates the coolant in the connecting pipe 503, thereby cooling the outdoor air flowing through the connecting pipe 503 until the outdoor air temperature reaches the required operating temperature.

[0047] During the cooling process, the coolant in the connecting pipe 503 cools the first heat-conducting element 501 and the second heat-conducting element 502 on both the upper and lower sides. This lowers the temperature of the first heat-conducting element 501 and the second heat-conducting element 502, and then transfers the cooling energy to the two first expansion joints 304 on the left side. The two outer first expansion joints 304 then transfer the cooling energy to the two inner second expansion joints 306, thus keeping the temperature of both the two first expansion joints 304 and the two second expansion joints 306 at a low level.

[0048] During the air conditioning process, the outdoor air flows downward under the guidance of the fixed cylinder 104. Under the action of the blower 109 drawing air to the right, the outdoor air flows to the right. During the process of the outdoor air flowing to the right, it first comes into contact with the two inner second expansion joints 306. When the moisture in the outdoor air passes through the relatively cool second expansion joints 306, the moisture in the outdoor air is adsorbed by the second expansion joints 306, thereby reducing the moisture contained in the outdoor air.

[0049] The moisture on the inner wall of the second telescopic member 306 adheres to foreign objects in the outdoor air, thus filtering the foreign objects contained in the outdoor air. The moisture on the inner wall of the second telescopic member 306 gradually condenses into water droplets, which are then adsorbed by the adsorption member 305. After being purified and filtered by the second telescopic member 306, the outdoor air flows to the right through the air outlet of the second telescopic member 306. During the process of the outdoor air flowing to the right through the air outlet of the second telescopic member 306, the moisture in the outdoor air is adsorbed again by the two outer first telescopic members 304, thereby repeatedly filtering the foreign objects and moisture contained in the indoor air, greatly reducing the foreign objects and moisture contained in the indoor air.

[0050] After being filtered and purified, the outdoor air flows to the right from the air outlet on the right side of the first telescopic component 304. During the flow of the outdoor air, it comes into contact with the connecting pipe 503 on the right side. The connecting pipe 503 cools down the filtered and purified outdoor air, so that the temperature of the outdoor air reaches the temperature required for operation.

[0051] During the filtration and purification of outdoor air, the second drive motor 3013 is activated via the control terminal. As the second drive motor 3013 rotates, it drives the second rotating component 301 and its components to rotate. The second telescopic component 306, the first telescopic component 304, and the adsorption component 305 filter and purify the outdoor air during rotation, ensuring that the second telescopic component 306 and the first telescopic component 304 are in uniform contact with the outdoor air. This prevents the right side of the second telescopic component 306 and the first telescopic component 304 from being in constant contact with the outdoor air, which would cause excessive moisture accumulation in the second telescopic component 306 and the first telescopic component 304, thus affecting their filtration effect.

[0052] During rotation, the adsorption member 305 adsorbs water droplets inside the second telescopic member 306 and the first telescopic member 304 to reduce the water droplet content on the second telescopic member 306 and the first telescopic member 304.

[0053] During the process of filtering and purifying outdoor air, the control terminal controls the drive component 401 to pull the fixed frame 402 and the second sliding frame 303 and their components upward. As the second sliding frame 303 moves upward, it squeezes the adsorption component 305 through the first telescopic component 304 and the second telescopic component 306 on the upper side, causing the adsorption component 305 to deform and squeezing out the water droplets and foreign objects inside the adsorption component 305. After the water droplets and foreign objects in the upper side of the adsorption component 305 are squeezed out, they flow downward, so that the water droplets and foreign objects on the upper side of the adsorption component 305 are transferred to the lower side.

[0054] During the process of the first telescopic member 304 and the second telescopic member 306 squeezing the adsorption member 305, the surrounding gas is squeezed by the first telescopic member 304 and the second telescopic member 306, causing the gas around the first telescopic member 304 and the second telescopic member 306 to flow. The generated gas is blown to all sides through the air outlet of the first telescopic member 304 and the second telescopic member 306, accelerating the downward flow speed of foreign objects and water droplets on the first telescopic member 304 and the second telescopic member 306.

[0055] During the process of squeezing the upper first telescopic member 304, the second telescopic member 306, and the adsorption member 305, the second sliding frame 303 moves upward to stretch the lower first telescopic member 304, the second telescopic member 306, and the adsorption member 305, causing the lower first telescopic member 304, the second telescopic member 306, and the adsorption member 305 to extend, and causing water droplets and foreign objects on the lower first telescopic member 304, the second telescopic member 306, and the adsorption member 305 to flow downward and into the collection box 3011 through the connecting pipe 3012.

[0056] After the first telescopic member 304, the second telescopic member 306, and the adsorption member 305 on the upper side are processed, the driving member 401 is controlled by the control terminal to push the fixed frame 402 and the second sliding frame 303 and their parts downward. During the downward movement, the fixed frame 402 squeezes the adsorption member 305 through the first telescopic member 304 and the second telescopic member 306 on the lower side, so that the water droplets and foreign objects in the adsorption member 305 are squeezed out and flow downward. The downward flowing water droplets and foreign objects flow into the collection box 3011 through the connecting pipe 3012, and the collection box 3011 collects the water droplets and foreign objects.

[0057] The control terminal controls the drive unit 401 to cause the fixed frame 402 and the second sliding frame 303 and their parts to move back and forth indirectly. This causes the first telescopic member 304 and the second telescopic member 306 on the upper and lower sides to squeeze the adsorption member 305, thereby reducing the content of water droplets and foreign objects in the adsorption member 305. This enhances the filtration effect of the first telescopic member 304, the second telescopic member 306 and the adsorption member 305 on outdoor air. Under the action of the reciprocating movement of the first telescopic member 304 and the second telescopic member 306 on the upper and lower sides, the conduction of cold energy is accelerated, and the cold energy transfer effect of the first telescopic member 304 and the second telescopic member 306 on the upper and lower sides is enhanced.

[0058] When the air conditioning is no longer needed, the cooling component 504, the circulation component 505, and the second drive motor 3013 can be turned off via the control terminal.

[0059] Example 3: Based on Example 2, such as Figure 3 and Figure 6As shown, it also includes a windproof component 2, which is disposed in the air inlet duct 105. The windproof component 2 is used to block outdoor wind from entering the air inlet duct 105. The windproof component 2 includes a first rotating member 201, which is rotatably connected to the air inlet duct 105. An arc-shaped plate 202 is fixedly connected to the first rotating member 201. A guide member 204 is fixedly connected to the outer periphery of the arc-shaped plate 202. The guide member 204 is used to divert the gas. A first drive motor 203 is disposed on the lower side of the air inlet duct 105. The power output shaft of the first drive motor 203 is fixedly connected to the first rotating member 201. By rotating the arc-shaped plate 202 and the guide member 204 to the windward side, the outdoor wind on the windward side is blocked. The first drive motor 203 is electrically connected to the control terminal.

[0060] The wind direction and speed are monitored by the wind direction and speed measuring instrument 103. When there is wind outdoors, the wind direction and speed measuring instrument 103 transmits the signal to the control terminal. The control terminal controls the first drive motor 203 to drive the first rotating part 201, the arc plate 202 and the guide part 204 to rotate, so that the first rotating part 201, the arc plate 202 and the guide part 204 rotate to the same direction as the outdoor wind direction, so that one side of the arc plate 202 and the guide part 204 on the first rotating part 201 contacts the windward side. The arc plate 202 blocks the outdoor wind on the windward side, and the guide part 204 diverts the outdoor wind to reduce the load on the arc plate 202 when it is facing the wind.

[0061] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
