Description

A square winter and summer dual-purpose air supply port that is easy to process

technical field

The invention relates to a partial component of ventilation and air conditioning, in particular to an air supply port, in particular to a square dual-purpose air supply port for winter and summer which is easy to process.

Background technique

The function of the air supply port is to send the air treated by the air conditioning system into the room. Taking the lobby of a building to supply air downward from the ceiling (top air supply) as an example, there are two requirements for the air supply port.

One is the air supply distance, also known as the air supply jet range. If the range is too short (for example, the height of the lobby is 9m, and the range of the air outlet is 5m), the jet (cold air or hot air) will not reach the area where the human body is, and the air conditioning effect will not be achieved. If the range is too long (for example, the height of the lobby is 9m, and the range of the air outlet is 15m), the jet (cold wind or hot wind) will blow to the area where the human body is located, and the wind speed will be too high, causing a feeling of blowing and causing discomfort to the human body.

The second is the diffusion range of the air supply, which corresponds to the air supply distance. If the diffusion range of the air supply is too large, the air supply will spread to places that do not need the air supply, resulting in waste of energy. If the diffusion range of the air supply is too small, the air supply will not cover the entire air supply area, and the air conditioning effect will not be achieved.

The two concepts of air supply distance and air supply diffusion range are contradictory concepts. The larger the air supply distance, the smaller the air supply diffusion range, and the smaller the air supply distance, the larger the air supply diffusion range. That is to say, for the air conditioning system, it is particularly important to select the tuyere with the appropriate air supply distance and air supply diffusion range.

In addition, today's air conditioning systems are generally dual-purpose systems in winter and summer, sending warm air in winter and cold air in summer. The air supply in winter is warm air from top to bottom, and the surrounding air is cold. Then, the air supply jet will have an upward movement tendency under the effect of buoyancy. Therefore, it is more difficult for the jet to be sent to the ground, and the single diffusion is better, that is, a larger air supply distance and a smaller air supply diffusion range are required. On the contrary, in summer, the air supply also sends warm air from top to bottom, and the surrounding air is hot. Then, the air supply jet will have a downward movement tendency under the effect of buoyancy. Therefore, the jet is easier to send to the ground, and the single diffusion is poor. That is to say, a smaller air supply distance and a larger air supply diffusion range are required. This requires that the air supply outlets have different air supply ranges in winter and summer.

To sum up, the two most important parameters of the tuyere are the air supply distance and the air supply diffusion range, and a tuyere is required to have two different air supply distances and air supply diffusion ranges. In winter, the long air supply distance and the air supply diffusion range are required. Large range, short air supply distance and large air supply diffusion range are required in summer.

In response to the above problems, dual-purpose air supply outlets in winter and summer with adjustable air supply distance and air supply diffusion range have emerged as the times require. There are several common air supply range adjustable air outlets:

1) The utility model name is the Chinese patent application (application number: 01208882.X) of electric adjustable tuyere, see Figure 1. In this solution, the air outlet adjusts the length of the air jet through an air valve. The air valve is fully open, the air supply volume is the largest, the air supply range is the largest, and the resistance is the smallest. It can be used in winter conditions.

2) The utility model name is adjustable style Chinese patent application (application number: 02248976.2), see Figure 2. In this solution, the tuyere adjusts the length of the air jet by changing the area of the tuyere. If the air outlet area is adjusted smaller, the air supply volume will be smaller, the air supply range will be smaller, and the resistance will be the largest, which can be used in summer working conditions. If the area of the tuyere is increased, the air supply volume will be larger, the air supply range will be larger, and the resistance will be the smallest, so it can be used in winter conditions.

3) The title of the invention is a Chinese patent application (application number 201410315250.4) for a multi-stage push-type adjustable air volume vent, see Figure 3. In this scheme, by adjusting the local resistance coefficient of the air supply port, when the resistance coefficient is large, the air supply volume is small, the air supply range becomes smaller, and the resistance is the largest, which can be used in summer working conditions. When the resistance coefficient is small, the air supply volume is large, the air supply range becomes larger, and the resistance is the smallest, so it can be used in winter conditions.

To sum up, the above methods or devices have certain innovation and applicability, but there are generally two problems in the actual implementation: (1) When adjusting the air supply range, the air supply volume will change, resulting in insufficient air supply volume Or too large, resulting in overcooling or overheating of the indoor air environment. (2) When adjusting the range of the air supply, the pressure of the air supply will change, resulting in a change in the working state of the fan, which will cause the fan to waste energy in vain and even cause the fan to burn out due to overload.

A sealing device is provided at the junction of the first embeddable square ring mouth gradual expansion 4 and the shell 10 .

The shell 10 is a hollow rectangular shell with one end open, its open end is used to install the fan, and its closed end is used to install the air outlet; The axes are parallel and the direction of the reduction and expansion of the two is opposite; the larger end of the first embeddable square ring mouth gradually expands out of the side wall of the closed end of the shell 10, and is fixedly connected with the side wall of the shell 10; the first S-shaped square The mouth elbow is installed vertically and its lower end is connected with the smaller end of the first embeddable square ring mouth; the second S-shaped square mouth elbow is installed vertically and its lower end is gradually expanded with the second embeddable square ring mouth The smaller end of the expansion is connected, and its upper end extends into the gradual expansion of the first embeddable square ring mouth and its upper end port is located at the port center of the larger end of the first embeddable square ring mouth gradual expansion, and the two form a ring The square air outlet and the square air outlet embedded in the center of the square annular air outlet, that is, the lower end port of the second S-shaped square mouth elbow; The connection is provided with a sealing device.

The gradual expansion of the first embeddable square ring mouth and the gradual expansion of the second embeddable square ring mouth of the present invention refer to a square passage and a bell mouth-shaped passage connected as one. The cross section of the trumpet-shaped channel is square, and the longitudinal section is trapezoidal. The first S-shaped square mouth elbow is embedded in the trumpet-shaped channel.

Design idea of the present invention is as follows:

(1) Inner square air outlet, outer ring air outlet

The reason why the inner square air outlet and the outer annular air outlet are chosen is because the square air outlet is easy to manufacture and process, and can better meet the economical requirements.

(1) Range adjustment:

The present invention designs a sandwich tuyere, that is, a combined tuyere formed by a square annular air outlet and an embedded square air outlet, as shown in FIG. 4 . The air outlet area of the square annular air outlet is larger than the square air outlet embedded in it. Under the same air volume, air supply speed = air volume ÷ air outlet area. That is to say, under the same volume, the larger the area of the air supply port, the smaller the air supply speed. The air supply range is related to the air supply speed, the greater the air supply speed, the shorter the air supply range. That is to say, under the same air supply volume, the range of the wind emitted from the small-area square air outlet is longer, while the range of the wind emitted from the large-area square annular air outlet is shorter.

Therefore, the present invention creates different combinations of air volumes (for example, 40% of the air volume enters the large-area square annular air outlet, and 60% of the air volume enters the small-area square air outlet) through the joint wrench, the chute, and the flexible partition. Through the combination of different air volumes, the air supply speed changes in the large-area square circular air outlet and the small-area square air outlet. This ultimately leads to finishing the range length of the combined supply air jet.

That is the air-supply jet of the present invention has two aspects to form, and the one, the jet that small-area square air outlet sends, the 2nd, the air-supply jet that large-area annular tuyere sends. The two jets merge together and are sent into the architectural space. If the proportion of air volume sent into the small-area square air outlet is large (100% in the extreme case is injected from the small-area square air outlet). Then, under the same air volume, the air supply speed is high, and the air supply jet is long. If the proportion of air volume sent into the large-area square annular air outlet is large (100% is completely injected from the large-area square annular air outlet in the extreme case). Then, under the same air volume, the air supply speed is small, and the air supply jet is short.

That is to say, the wind speed, that is, the range adjustment can be carried out by this method.

(2) Equal resistance, equal air volume adjustment:

The present invention designs two air-supply passages with completely equal resistance, and only adjusts the air-supply range by the ratio of the air-supply volumes sent into different air-supply passages, as shown in FIG. 5 . The maximum resistance components in the two channels are respectively the first S-shaped square elbow and the first embeddable square ring gradually expanding, and the second S-shaped square elbow and the second embeddable square ring gradually expanding. The shape of the first S-shaped square elbow is similar to that of the second S-shaped elbow, and the resistance coefficient is the same. same. Therefore, the resistance caused by the first S-shaped square mouth elbow + the resistance caused by the gradual expansion of the first embeddable square ring mouth = the resistance caused by the second S-shaped square mouth elbow + the gradual expansion of the second embeddable square ring mouth resistance to expansion. That is to say, the air resistance in the two channels is exactly the same. Either the upward adjustment of the air volume adjustment wrench drives the flexible partition to move upward, resulting in smaller upper space and smaller air intake, or downward adjustment of the air volume adjustment wrench to drive the flexible partition to move downward, resulting in smaller lower space and smaller air intake. Its resistance does not change during the conditioning process, only the air volume ratio changes with the upward and downward movement of the air volume adjustment wrench.

The shell in the present invention is directly connected to the air duct, and the position change of the air volume adjustment wrench directly causes the flexible partition to cut and divert the air in the air duct. If the position of the air volume adjustment wrench is higher, the air volume in the upper air supply channel will be larger, and vice versa, the air volume in the lower air supply channel will be larger, as shown in Figure 6.

Also, since the resistance in the upper and lower channels is the same, it is adjusted regardless. There is no change in the resistance caused by the upper and lower channels. That is to say, no matter how it is adjusted, the resistance of the entire tuyere does not change, that is, the pressure loss does not change.

That is to say, the adjustment of the air supply range under the condition of constant resistance and constant air volume can be realized through the above process.

(3) The integrity and necessity of the interconnection of the air volume adjustment device, the air duct diversion device, and the combined air outlet

The air volume adjustment device includes an air volume adjustment wrench, a chute, and a flexible partition. The air duct diversion device includes a first S-shaped square mouth elbow, a first embeddable square ring mouth gradually expanding, a second S-shaped square mouth elbow, and a second S-shaped square mouth elbow. Two, the built-in square ring mouth gradually expands. Combined air outlets include square ring air outlets and square air outlets. Because the purpose of the present invention is not to change air volume, adjust tuyere range under the condition of resistance. The present invention supplies air to combined tuyeres with different areas through two independent channels with the same resistance, and realizes changes in wind speed through the inverse proportional relationship between the area and wind speed, thereby finally leading to a change in the range of the combined tuyeres. Therefore, the first condition is to divide the air sent by the air duct into two independent air parts, which requires an air volume adjustment device; secondly, to send the divided air into two separate air parts with the same resistance A duct system is required to prepare for the air supply from the tuyere, which requires an air duct splitter. Finally, the diverted air is sent into the room, which requires combined air outlets.

In order to realize the above-mentioned process, the present invention innovatively designed the first S-shaped square mouth elbow, the first embeddable square ring mouth gradual expansion, the second S-shaped square mouth elbow, and the second embeddable square ring mouth gradual expansion. The combination of these four components forms two air passages with completely equal resistance and effectively divided air. Finally, through two independent air passages, it is sent into the combined air outlet, and the air supply speed changes in the square and square ring air outlets in the combined air outlet, resulting in the change of the range of the combined air supply without changing the resistance and air volume. .

The working principle of the present invention is as follows:

When the present invention works, at first the air is sent into the casing 10 by the air duct, and the air sent in is divided into upper and lower parts by the flexible partition 9, and the upper part of the air flows into the upper air supply channel, and the upper air supply channel is formed by the upper part of the casing 10. , the first S-shaped square mouth elbow, the first embeddable square ring mouth gradually expanding and the square air outlet; Two S-shaped square mouth elbows and the second embeddable square ring gradually expand; the resistance in the upper air supply channel and the lower air supply channel are exactly the same, that is, the first S-shaped square mouth elbow and the first embeddable The resistance sum of the gradual expansion of the square ring mouth is equal to the resistance sum of the gradual expansion of the second S-shaped square mouth elbow and the second embeddable square ring mouth. The amount of air flowing into the upper air supply channel and the lower air supply channel is adjusted by the air volume adjustment wrench 1 and the chute 2 connected with the flexible partition. After the air flows into the upper air duct, it passes through the first S-shaped square mouth elbow and the first embeddable square ring mouth and gradually expands, and then is sent into the square ring air outlet and then sent out from the square ring air outlet. After the air flows into the down-supply duct, it passes through the second S-shaped square mouth bend and the second embeddable square ring mouth and gradually expands, and then is sent into the square air outlet and then sent out from the square air outlet. Due to the different areas of the square air outlet and the square ring air outlet, the air outlet speed is different under the same air volume. If long-jet range air supply is required, the air volume adjustment wrench 1 is adjusted upwards so that the proportion of the air volume entering the lower passage is larger. And if the air supply with a shorter jet range is needed, the air volume adjustment wrench 1 is adjusted downwards, so that the proportion of the air volume entering the upper channel is larger.

The area ratio of the square annular air outlet 6 and the square air outlet 5 is determined by the maximum and minimum distances of the air outlet range. If all the air volume is sent from the up-supply air duct, the range is the shortest, which meets the summer operating conditions for short range requirements. If all the air volume is sent from the downflow duct, the range is the longest, which meets the winter working conditions with long range requirements.

Resistance and equal mechanism characteristics guarantee:

According to the well-known in the field of HVAC, the local resistance of the pipeline can be calculated by the following formula.

The local resistance formula of the pipe fitting is:

The local components in the upper air duct include the first S-shaped square elbow (3), the first embeddable square ring gradually expanding (4)

The sum of its local resistance is

The local components in the downflow channel include the second S-shaped square elbow (7), the second embeddable square ring gradually expanding (8)

The sum of its local resistance is

Because the second S-shaped square mouth elbow (7) has the same structure as the first S-shaped square mouth elbow (3), the first embeddable square ring mouth gradually expands (4) and the second embeddable square ring mouth Gradual expansion (8) has the same structure. Therefore, under the conditions of winter working conditions and summer working conditions respectively,,,,. Therefore, that is to say, the resistance under winter conditions and summer conditions is exactly the same.

The area ratio of the square annular air outlet and the square air outlet is determined:

The longest and shortest range of the jet can be determined according to the following calculation formula.

In the formula, a is the degree of turbulence, which is determined according to the square or square annular tuyere, and the value is 0.1 to 0.2, which is the wind speed of the square or square annular tuyere. The diameter is the range.

Also, according to the calculation formula of air volume:

, that is, the calculation formula of the input range is

Since it is known, it is 0.5m/s, and a is known, and it is 0.1 to 0.2. It is known that there are well-known calculation methods in the field of HVAC, so the air supply range x is actually a function of the hydraulic diameter of the tuyere, ie. Therefore, according to the maximum range of the square nozzle in winter conditions (determined by the building space, known in the field of HVAC), the square nozzle can be solved. Similarly, according to the maximum range of the annular nozzle in summer conditions (determined by the building space, known in the field of HVAC), the solution of the annular nozzle is obtained. This results in the area ratio between the square spout and the annular spout.

Example:

Specific embodiments of the present invention are provided below, and it should be noted that the present invention is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the technical solutions of the present application all fall within the scope of protection of the present invention.

According to the above technical scheme, the size of the wrench 1 for adjusting the air volume is 100mm×20mm×20mm; the size of the chute 2 is 1000mm×10mm×20mm; mm, height 370 mm, width 190 mm; the first inlaid square ring gradually expands and the second inlaid square ring gradually expands. The front diameter is 100 mm, the rear diameter is 300 mm, and the length is 230 mm. The diameter of the square air outlet is 100mm, the inner diameter of the square ring air outlet is 100mm, and the outer diameter is 300mm. The area of the flexible partition is 700mm×500mm, and the size of the housing 10 is 750mm×500mm×1000mm.

When the present invention starts to be used, through adjustment, the lengths of different air supply jets formed are shown in FIG. 9 . It can be seen that under the conditions of constant air volume and constant resistance, the present invention can effectively realize the change of jet length.

At the same time, sort out the air supply range values under the different air supply ratios of the upper air duct and the lower air duct. It can be seen that the relationship between the up and down movement distance of the air volume adjustment wrench and the range is shown in the following formula:

In the formula, y is the range, d is the diameter of the square air outlet, which is 100mm in this example, x is the height of the air volume adjustment wrench from the bottom surface, and D is the size of the air duct at the interface, which is 1000mm in this example. It can be seen that under the condition of the diameter of the square air outlet and the size of the interface air pipe, the range and the height of the air volume adjustment wrench from the bottom surface are linearly related, and it can be adjusted conveniently.

What has been described above is only the preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, some changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the present invention. scope of protection.
