TECHNICAL FIELD

[0001] The present application belongs to the technical field of air conditioners, and particularly relates to an air supply pipeline of an air conditioning device and a temperature control method. BACKGROUND

[0002] The existing air conditioner has a single air outlet direction, and the air outlet angle can only be slightly adjusted in the current air outlet direction by setting a deflector and louvers, the indoor temperature is uneven, and the temperature adjustment speed is slow.

[0003] When it is necessary to adjust the temperature of a larger indoor environment, a lengthened air supply pipeline is usually used, so that the air supply pipeline has a longer air outlet to achieve a more uniform temperature change at each position of the indoor environment.

[0004] Therefore, the present application is proposed. SUMMARY

[0005] The present application aims to overcome the shortcomings of the prior art and provide an air supply pipeline of an air conditioning device and a temperature control method.

[0006] To solve the above technical problems, the basic idea of the technical solution of the present application is as follows: an air supply pipeline of an air conditioning device, comprising:

[0007] The air supply pipeline comprises a plurality of air supply modules arranged in sequence and connected in sequence, and each air supply module is provided with a booster fan at the air inlet.

[0008] The air supply module has an air outlet, and the air outlet position is provided with a temperature detection device.

[0009] According to the above scheme, the air inlet position of each air supply module is provided with a booster fan, and the airflow flow rate flowing into each air supply module is increased by the booster fan, so that the airflow flow rate blown out at the air outlet position close to the air inlet side and the air outlet position away from the air inlet side is relatively balanced, thereby achieving balanced air outlet speed of the multiple air outlets. The temperature detection device is arranged at the air outlet position, and the temperature change of the target area at the air outlet position is detected by the temperature detection device, wherein each booster fan can be adjusted according to the monitoring temperature of each temperature detection device to make the temperature change at each position of the long-distance air outlet as consistent as possible.

[0010] Further, each of the air supply modules is provided with an air pressure sensor for monitoring the air pressure in the air supply module.

[0011] Through the above scheme, the booster fan can be accurately controlled based on the temperature monitoring data and the air pressure change relationship, and the temperatures at the positions of the multiple air outlets are kept as close as possible.

[0012] Further, the air outlet of the air supply module is provided with a flow guide component capable of adjusting the air outlet angle.

[0013] Through the above scheme, when the temperatures at different positions of the indoor environment are greatly different due to other reasons, the air outlet angle can be adjusted by the flow guide component to form a targeted temperature control effect.

[0014] Further, the air supply module is provided with a detachable mesh, and the meshes of the adjacent air supply modules are interconnected.

[0015] Through the above scheme, when an odor or the like occurs, the existing mesh can be detached, and a new mesh can be replaced to clean the air supply pipeline.

[0016] Further, the mesh is provided with multiple air outlet nozzles on the side facing the air outlet.

[0017] The application also provides a temperature control method of an air supply pipeline, including an air supply pipeline, and the control method of the air supply pipeline includes:

[0018] S1: a temperature sensor acquires temperature data at the position of the air outlet of the corresponding air supply module;

[0019] S2: a temperature difference between a set temperature and a measured temperature is calculated;

[0020] S3: air volume demand is calculated based on the amplitude of the temperature difference;

[0021] S4: the air volume of the module is adjusted according to the air volume demand.

[0022] Through the above scheme, the control unit can use the temperature data acquired by the temperature sensor as a basis for judgment and control the booster fan of the corresponding air supply module, so that the temperature at the position of the air outlet of each air supply module is kept relatively close, the change in the temperature difference at each position of the indoor environment is as small as possible, the temperature control efficiency of the air conditioner is improved, and the user's experience is also improved, especially for the structure of the long-distance air supply pipeline, the effect is particularly significant.

[0023] Further, the temperature sensor is installed at a position above the air outlet and is arranged obliquely, so that the temperature sensor can be used to monitor the temperature of the area in front of the air outlet.

[0024] Through the above scheme, the temperature sensor is used to monitor the temperature of the area in front of the air outlet, so that the data actually monitored by the temperature sensor is the temperature in the change of the indoor environment, thereby avoiding a large deviation between the temperature monitored at the position of the air outlet and the actual temperature in the indoor environment, and causing the temperature sensor to display that the set temperature has been reached after the temperature in the indoor environment has not yet reached the temperature set by the user, thereby causing the air conditioner to stop running.

[0025] Further, in the step S2, when the absolute value of the temperature difference is greater than the first threshold value, a step response mode is used to output the limit air volume;

[0026] When the absolute value of the temperature difference is less than the second threshold value, a step-by-step fine adjustment mode is used to adjust the air volume.

[0027] When the absolute value of the temperature difference is in an intermediate range, a compensation air volume is provided by the booster fan, and the compensation air volume tends to approach an upper limit value as the temperature difference increases.

[0028] Through the above scheme, according to the set first threshold value and the second threshold value, different air volume changes are selected, so that the temperature change of the indoor environment can be quickly controlled, and since the temperature data monitored by the temperature sensor is the actual temperature of the indoor environment, the temperature control efficiency is improved, and the air conditioner is prevented from running excessively, thereby avoiding energy waste.

[0029] Further, in the step response mode, the air volume is adjusted instantaneously to a maximum or minimum value.

[0030] Further, in the step-by-step fine adjustment mode, the air volume is increased or decreased.

[0031] After adopting the above technical scheme, the present application has the following beneficial effects compared with the prior art.

[0032] The booster fan is arranged at the air inlet position of each air supply module, and the flow rate of the airflow flowing into each air supply module is increased by the booster fan, so that the flow rates of the airflows blown out at the air outlets near the air inlet side and away from the air inlet side are relatively balanced, thereby achieving balanced air outlet speeds of the multiple air outlets. The temperature detection device is arranged at the air outlet position, and the temperature change of the target area at the air outlet position is detected by the temperature detection device. Each booster fan can be adaptively adjusted according to the monitored temperature of each temperature detection device, so as to keep the temperature changes at different positions of the long-distance air outlet as consistent as possible.

[0033] The control unit can take the temperature data obtained by the temperature sensor as a basis for judgment, and control the booster fan of the corresponding air supply module, so that the temperature at the air outlet position of each air supply module is kept relatively close, and the temperature difference at each position of the indoor environment is as small as possible, which can improve the temperature control efficiency of the air conditioner and improve the user experience, especially for the structure of the long-distance air supply pipeline.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0043] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0044] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] As Figures 1 to 3 shown, the air supply pipeline of the air conditioning equipment comprises an air supply duct 1, the air supply duct 1 comprises a plurality of air supply modules 100 arranged in sequence and communicated in sequence, and each air supply module 100 is provided with a booster fan 3 at an air inlet 101.

[0046] The air supply module 100 has an air outlet 102, and a temperature detection device is arranged at the position of the air outlet 102.

[0047] In the prior art, in the case of long-distance air supply, the length of the air supply pipeline needs to be increased, that is, the length of the air outlet 102 is increased, so that the air supply flow can be uniformly diffused in the indoor environment, so that the temperature change at each position in the indoor environment is relatively uniform, and the temperature difference between multiple positions is avoided. Large, thereby reducing the temperature control efficiency of the air conditioner and reducing the user's use experience.

[0048] In order to solve the above technical problems, in the embodiments of the present application, the booster fan 3 is arranged at the position of the air inlet 101 of each air supply module 100, and the airflow velocity flowing into each air supply module 100 is increased through the booster fan 3, so that the airflow velocity blown at the positions of the air outlet 102 close to the air inlet 101 side and the air outlet 102 away from the air inlet 101 side is kept relatively uniform, thereby realizing the uniformity of the air outlet speed of the multiple air outlets 102.

[0049] Further, in order to ensure that the temperature change at each position in the indoor environment is kept relatively uniform, a temperature detection device can be arranged at the position of the air outlet 102, as shown in Figure 1 and Figure 2The temperature change of the target area at the position of the air outlet 102 is detected by the temperature detection device, and each booster fan 3 can be adjusted adaptively according to the monitored temperature of each temperature detection device to keep the temperature change at each position of the long-distance air outlet 102 as consistent as possible, thereby improving the temperature control effect on the whole indoor environment and improving the user experience.

[0050] To further improve the precise control of the booster fan 3 on the air supply amount, a wind pressure sensor is arranged in each air supply module 100 to detect the wind pressure in the air supply module 100, so that the booster fan 3 can be precisely regulated and controlled based on the temperature monitoring data and the wind pressure change relationship, and the temperatures at the positions of the multiple air outlets 102 are kept as close as possible.

[0051] Optionally, referring to Figure 3 The air outlet 102 of the air supply module 100 can be provided with a flow guide assembly capable of adjusting the air outlet angle. When the temperatures at different positions of the indoor environment differ greatly due to other reasons, the air outlet angle can be adjusted by the flow guide assembly to form a targeted temperature control effect, so that the temperature difference at different positions of the indoor environment remains similar. The above-mentioned reason for the temperature change can be that the mechanical equipment or other heat sources cause a large temperature difference between the partial area and the other area of the indoor environment. By using the above-mentioned flow guide assembly, the airflow blown out of the air outlet 102 can be targeted to the position of the heat source for targeted cooling, thereby avoiding the heat radiation of the heat source to the surrounding environment, which causes a large temperature difference between different positions of the indoor environment. The heat source is not limited in the present application, and therefore will not be described here.

[0052] Optionally, a sleeve net 2 can be arranged in the air supply module 100, the sleeve net 2 and the air supply module 100 are detachably connected, and a plurality of air outlet nozzles are arranged on the side of the sleeve net 2 facing the air outlet 102. The temperature of the airflow in the air supply module 100 changes frequently under the control of the user, and condensate water is generated in the air supply module 100 during the process of frequent change of the temperature of the airflow. If the condensate water in the air supply module 100 cannot be discharged in time, it will cause mold or odor in the air supply module 100. In order to facilitate cleaning of the air supply module 100, a detachable sleeve net 2 can be arranged in each air supply module 100, and the sleeve nets 2 arranged adjacent to each other are connected to each other, so that the sleeve net 2 can satisfy the mutual connection between the multiple air supply modules 100, and the air outlet nozzles arranged on the sleeve net 2 facing the air outlet 102 can ensure good air outlet effect. The user can periodically or when odor is found to detach the existing sleeve net 2 and replace a new sleeve net 2 to clean the air supply module 100. This cleaning method not only improves the cleaning efficiency, but also is particularly prominent in the characteristics of easy cleaning for long-distance air supply pipelines.

[0053] It should be noted that the detachable connection mode is also adopted between the plurality of air supply modules 100, and the user can disassemble the plurality of air supply modules 100 according to the actual situation, and then take out the sleeve net 2 from the air supply module 100. Alternatively, the user can replace the sleeve net 2 of part of the air supply module 100.

[0054] Optionally, the inner diameter of the sleeve net 2 gradually decreases along the airflow direction of the air supply module 100, so that the air flow is pressurized, and the air supply effect of different positions of the air outlet 102 of the corresponding air supply module 100 can also be kept relatively balanced. In the case of maintaining the above air supply effect for each air supply module 100, the air supply effect of each position of each air outlet 102 of the long-distance air supply pipeline can be kept balanced, thereby improving the overall air supply and temperature control effect on the indoor environment.

[0055] Reference Figure 4 The embodiment of the present application also provides a temperature control method of an air supply pipeline, comprising:

[0056] S1: The temperature sensor 4 acquires temperature data at the position of the air outlet 102 of the corresponding air supply module 100;

[0057] S2: Calculate the temperature difference between the set temperature and the measured temperature;

[0058] S3: Segmentally calculate the air volume demand based on the amplitude of the temperature difference;

[0059] S4: Adjust the air volume of the air supply module 100 according to the air volume demand.

[0060] Optionally, the temperature sensor 4 in step S1 is arranged at a position above the air outlet 102 and points downward to the target area at an inclination angle of 45°, so that the temperature sensor 4 can be used to monitor the temperature of the area in front of the air outlet 102. Specifically, the temperature sensor 4 can cover an area of about 1.5 meters in radius in front of the air outlet 102, so as to accurately collect the temperature of the target area. When the temperature sensor 4 can monitor the temperature of the target area in front of the air outlet 102, the temperature at each position in the target area can be judged, and when the monitoring result is that the temperature difference change in the target area is relatively small, it indicates that the temperature adjustment change of the indoor environment can also be in a relatively balanced control state.

[0061] In step S2, the air volume demand is calculated based on the amplitude of the temperature difference, and the specific calculation method is:

[0062] ΔT = T set -T local

[0063] The autonomous air volume demand Qi is calculated by using the air volume decision function.

[0064]

[0065] wherein Q base = module base air flow (default setting value);

[0066] K = module maximum compensation air flow (determined by fan performance curve);

[0067] σ = temperature sensitivity coefficient (value range 0.5-1.0, default 0.8);

[0068] ΔT = set temperature and measured temperature deviation;

[0069] The execution logic is:

[0070] When |ΔT|>2℃, trigger step response mode: air flow is instantaneously adjusted to the limit value Q max or Q min ;

[0071] When |ΔT|≤0.5℃, enter fine adjustment mode: air flow changes in steps of ±5%.

[0072] Preferably, the air supply module 100 can also be provided with an air pressure sensor, which is arranged at a position 10 cm away from the air outlet, and real-time feedback of the air pressure change in the air supply module 100 provides a basis for air flow adjustment.

[0073] Further, when the temperature sensor 4 and the air pressure sensor continuously sample deviation for three times exceeding the threshold value (for example, temperature sensor 4 monitoring data |ΔT|>5℃; and air pressure sensor reading fluctuation >20%), the control unit can determine that the air supply module 100 has a fault, and the control unit can send a fault reminder to the user, so that the user can quickly judge the air supply module 100 that has a fault and take corresponding measures as soon as possible.

[0074] Preferably, based on the data of the temperature sensor 4 and the air pressure sensor, when it is determined that one of the air supply modules 100 has a fault, the control unit can adjust another air supply module 100 located upstream of the air supply module 100 that has a fault, and can increase or decrease the air supply air flow of the upstream air supply module 100, so as to ensure the air supply air flow of the air supply module 100 that has a fault. In addition, when the air pressure of the air supply module 100 located upstream increases, the control unit can control the operation efficiency of the booster fan 3 of the air supply module 100 located downstream, so that the air pressure in the upstream air supply module 100 tends to be normal.

[0075] Preferably, the control unit can also adjust the angle of the air deflector, the air deflector can be a plurality of air deflectors arranged at the position of the air outlet 102, and the plurality of air deflectors can be connected with the control unit through the driving device, and the control unit controls the driving device to adjust the angle of the plurality of air deflectors, so as to achieve the targeted air supply effect on the local area of the indoor environment.

[0076] In the scheme of the present application, a plurality of booster fans 3 are used, the control unit can reduce the fan speed of the booster fan 3, and set the angle of the plurality of air deflectors to be the same as the orientation of the air outlet 102, through the above-mentioned way, the noise problem caused by the plurality of booster fans 3 can be reduced, and the way of setting the plurality of air deflectors in the same direction as the orientation of the air outlet 102 can also reduce the noise and reduce the loss of air volume. In the embodiment of the present application, the air supply pipeline is connected by a plurality of air supply modules 100 in sequence, so that the air supply pipeline can have a long-distance air outlet 102, wherein the air inlet 101 of the air supply pipeline is located at one end of the extension direction of the plurality of air supply modules 100, in order to avoid the problem of uneven air outlet speed of the air outlet 102 away from the air inlet 101 and the air outlet 102 close to the air inlet 101, a booster fan 3 is arranged at the air inlet position of each air supply module 100, and the booster fan 3 can be individually connected with the control unit, so that the control unit can individually control each booster fan 3, so that the air speed at the position of the air outlet 102 of each air supply module 100 is as uniform as possible, and the temperature control effect at different positions in the indoor environment is balanced. In order to further improve the temperature control effect of the above-mentioned air supply pipeline, a temperature sensor 4 is arranged at the position of the air outlet 102 of the air supply module 100, and a wind pressure sensor is arranged near the position of the air outlet 102 in the air supply module 100, and each temperature sensor 4 and wind pressure sensor is signal-connected with the control unit, and the control unit can adjust the running state of the booster fan 3 according to the monitoring data of the corresponding temperature sensor 4 and wind pressure sensor, so as to balance the air supply effect of the plurality of air supply modules 100.

[0077] In the specific implementation process, the air supply pipeline includes 4 air supply modules, and the set temperature is 24 DEG C. When the temperature sensor 4 of the third air supply module 100 monitors that the temperature difference of the target area is ΔT = + 2.5 DEG C due to the gathering of people, the temperature difference between the set temperature, at this time, the module 3 can improve the air volume by calculation, and at the same time, adjust the air deflector at the air outlet 102 position of the second air supply module 100 and the fourth air supply module 100, and the booster fan 3 of the fourth air supply module 100 is adjusted synchronously according to the air volume of the third air supply module 100, so as to avoid the influence of the air volume adjustment of the third air supply module 100 on the air supply effect of the fourth air supply module 100, and further, when the temperature sensor 4 monitors that the temperature of the target area is restored, the automatic return balance mode is restored. In this way, the long-distance air supply pipeline can realize rapid adjustment in the process of temperature change, and the operation mode of each air supply module 100 can be adjusted according to the specific situation, so as to ensure that the temperature control effect of the air supply pipeline reaches the best state.

[0078] The above only describes the preferred embodiments of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above-mentioned technical content without departing from the scope of the technical solution of the present application, and equivalent embodiments with equivalent changes are equivalent. The embodiments in the above examples can be further combined or replaced, but as long as it does not deviate from the technical solution of the present application, any simple modification, equivalent change and modification of the above examples according to the technical essence of the present application are still within the scope of the present application.
