[0036] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for determining a trajectory line of an air supply jet, comprising:

[0037] S101: The processor obtains steady-state operating parameters of the air conditioner.

[0038] S102: The processor simulates the air outlet state of the air conditioner according to the steady-state operation parameters.

[0039] S103, the processor determines the maximum wind speed point of the air supply jet trajectory of the air conditioner according to the simulated air outlet state.

[0040] S104: The processor determines the trajectory of the air supply jet according to the maximum wind speed point.

[0041] When the air conditioner is running stably, the processor of the air conditioner obtains the steady-state operating parameters of the air conditioner. Among them, the steady-state operating parameters include parameters such as return air temperature, supply air temperature, and supply air speed. Using simulation software, such as CFD (Computational Fluid Dynamics) simulation software, the air outlet state of the air conditioner is simulated according to the steady-state operating parameters such as return air temperature, supply air temperature, and supply air speed when the air conditioner is running stably. According to the simulated air outlet state, the maximum wind speed point of the air supply jet trajectory of the air conditioner is determined, and then the air supply jet trajectory line of the air conditioner is determined. That is, on the air supply jet trajectory line, the air supply speed of the air conditioner is the largest. The air supply jet trajectory line reflects the distribution law of the air supply speed and air supply temperature of the air conditioner.

[0042] According to the method for determining the trajectory of the air supply jet provided by the embodiment of the present disclosure, the steady-state operation parameters of the air conditioner are first obtained, and the steady-state air outlet of the air conditioner is simulated based on the steady-state operation parameters. Then, based on the simulation results, the maximum wind speed point of the air supply jet trajectory of the air conditioner is determined, and then the trajectory of the air supply jet is determined. In this way, the determination of the trajectory of the air supply jet of the air conditioner is realized through the simulation analysis of the steady state of the air conditioner, which is not only applicable to air conditioners with stable jet trajectories and single air outlets, but also applicable to air conditioners with dynamic changes in the air supply jet and complex and diverse air outlet forms. In this way, the maximum wind speed position can be identified for various forms of air conditioners, so as to facilitate the subsequent adjustment of the operation of the air conditioner, optimize the air supply effect of the air conditioner, efficiently exert the heat exchange effect of the air conditioner, reduce energy consumption, and improve the operating efficiency of the air conditioning system. By adjusting the air temperature and wind speed settings of the air conditioner, the trajectory of the air supply jet can better meet the local and overall temperature requirements of the room, thereby improving the comfort of the indoor environment and meeting the thermal comfort requirements of the user.

[0043] Combination Figure 2 As shown, the embodiment of the present disclosure provides another method for determining the trajectory of the air supply jet, including:

[0044] S111, the air conditioner operates according to preset air supply parameters.

[0045] S121, the processor obtains air supply parameters of preset measuring points when the air conditioner is in a stable operating state.

[0046] S131, the processor determines the steady-state air supply parameters of the air conditioner according to the air supply parameters of the preset measuring points.

[0047] S102: The processor simulates the air outlet state of the air conditioner according to the steady-state operation parameters.

[0048] S103, the processor determines the maximum wind speed point of the air supply jet trajectory of the air conditioner according to the simulated air outlet state.

[0049] S104: The processor determines the trajectory of the air supply jet according to the maximum wind speed point.

[0050] Through field tests or simulations, the air conditioner is operated according to the preset air supply parameters, wherein the preset air supply parameters include: preset temperature, preset air supply angle, preset air supply volume, preset air supply mode and other parameters. A first set of preset measuring points is set at the return air outlet of the air conditioner, and a second set of preset measuring points is set at the location where the air supply can reach. The steady-state operating parameters of the air conditioner include: steady-state return air temperature and steady-state supply air parameters. When the air conditioner is in a stable operating state, the steady-state return air temperature of the first set of preset measuring points and the steady-state supply air parameters of the second set of preset measuring points are obtained through the wind speed and temperature measurement system. Among them, the supply air parameters include supply air temperature and supply air speed.

[0051] Optionally, an average value of the return air temperatures of the first group of preset measuring points is used as the steady-state return air temperature.

[0052] The wind speed and temperature measurement system is arranged in the space where the air conditioner is located. Optionally, the wind speed and temperature measurement system includes a plurality of wind speed and temperature measurement rods, and a plurality of measurement points are taken on each measurement rod and along the height direction, and these measurement points form a second group of preset measurement points. A wind temperature and wind speed measurement sensor is arranged at each measurement point.

[0053] Optionally, whether the air conditioner is running stably is determined by the running time of the air conditioner. When the running time of the air conditioner reaches a set time, it is determined that the air conditioner is in a stable running state.

[0054] According to the parameters such as the supply air temperature and the supply air speed of the second set of preset measuring points, the supply air temperature and the supply air parameters are stabilized, and then the steady-state supply air parameters of the air conditioner are determined.

[0055] In this way, when the air conditioner is running stably, the return air temperature and supply air parameters of the preset measuring points are obtained to simulate the stable operation state of the air conditioner, which is convenient for the subsequent accurate determination of the supply air jet trajectory.

[0056] Optionally, at S131, the processor determines the steady-state air supply parameters of the air conditioner according to the air supply parameters of the preset measuring points, including:

[0057] The processor uses the average value of the low value section of the air supply temperature in each air supply cycle of the preset measuring point as the corresponding steady-state air supply temperature. The processor uses the average speed value of the fluctuation of the air supply speed in each air supply cycle of the preset measuring point as the corresponding steady-state air supply speed.

[0058] The air supply jet of an air conditioner, such as a split air conditioner, changes dynamically, so the air supply speed and air supply temperature also change dynamically. In order to obtain the air supply parameters of the air conditioner when it is in a steady state, it is necessary to stabilize the dynamically changing air supply speed and air supply temperature.

[0059] When the air conditioner is in steady state, the average air supply temperature and average air supply speed will change periodically and steadily over time. The air supply speed fluctuates around a stable value over time. For the air supply temperature, the temperature valley value of each change cycle is always kept at a stable value, and the average value of the lowest air supply temperature in each air supply cycle of the second group of prediction points is taken as the air supply temperature under steady state operation of the air conditioner, that is, the steady-state air supply temperature. For the air supply speed, the stable average speed value around which the air supply speed fluctuates in each air supply cycle of the second group of prediction points is taken as the air supply speed under steady state operation of the air conditioner, that is, the steady-state air supply speed.

[0060] In this way, by steady-state processing of the supply air temperature and the supply air speed, the steady-state supply air temperature and the steady-state supply air speed are obtained to accurately simulate the steady-state air outlet state of the air conditioner, which is conducive to determining the supply air jet trajectory line matching the air conditioner.

[0061] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for determining the trajectory of the air supply jet, including:

[0062] S101: The processor obtains steady-state operating parameters of the air conditioner.

[0063] S112: The processor obtains indoor environment parameters.

[0064] S122, the processor uses the indoor environmental parameters and the steady-state operating parameters as boundary conditions to simulate the air outlet state of the air conditioner.

[0065] S103, the processor determines the maximum wind speed point of the air supply jet trajectory of the air conditioner according to the simulated air outlet state.

[0066] S104: The processor determines the trajectory of the air supply jet according to the maximum wind speed point.

[0067] Temperature sensors are arranged on the four walls, ceiling, floor, lamps, doors and windows in the space where the air conditioner is located to detect the indoor ambient temperature. Steady-state air supply parameters such as steady-state return air temperature, steady-state supply air temperature, steady-state supply air speed, and indoor environmental parameters such as indoor environmental parameters and wall temperature are input into the simulation software as known boundary conditions to ensure that the simulation conditions are the same as the actual operating conditions, so that the simulation software can accurately simulate the operation of the air conditioner in the steady-state air outlet state.

[0068] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for determining the trajectory of the air supply jet, including:

[0069] S101: The processor obtains steady-state operating parameters of the air conditioner.

[0070] S102: The processor simulates the air outlet state of the air conditioner according to the steady-state operation parameters.

[0071] S113, the processor analyzes the distribution of air supply speed on the preselected air supply section.

[0072] S123, the processor determines the point with the maximum wind speed value on the pre-selected air supply section.

[0073] S104: The processor determines the trajectory of the air supply jet according to the maximum wind speed point.

[0074] When the simulation software simulates the steady-state operation of the air conditioner, the distribution of the air supply speed of the air conditioner is analyzed on the preselected air supply section. Optionally, there are multiple preselected air supply sections. Usually, the air supply outlet of the indoor unit of the split air conditioner is designed to be grille-shaped to send out multiple air flows, so the air supply jet of the air conditioner is generally composed of multiple air supply jets. By analyzing the air supply speed on multiple air supply sections, the point with the maximum wind speed value on the preselected air supply section is obtained.

[0075] In this way, by finding the point on the air supply jet trajectory line with the maximum air supply speed and determining the center point position of the air supply jet trajectory on the preselected section, multiple air supply jet trajectory lines can be converted into one air supply jet trajectory line.

[0076] Optionally, the air supply cross section is selected in the following way:

[0077] The processor uses the plane where the air outlet of the air conditioner is located as a reference plane.

[0078] The processor sequentially selects air supply sections parallel to the reference plane at multiple positions from near to far away from the reference plane.

[0079] Select multiple parallel sections near the plane where the air outlet of the air conditioner is located for analysis. Take the plane where the air outlet of the air conditioner is located as the reference plane, and select multiple air supply sections parallel to the reference plane from near to far away from the reference plane. An appropriate number of air supply sections must be selected to ensure that an accurate air supply jet trajectory can be drawn. If too many air supply sections are selected, the workload of processing data will increase. If too few air supply sections are selected, the accuracy of determining the air supply jet trajectory will decrease.

[0080] Optionally, when the distance from the reference plane is less than or equal to the set distance, a first set number of air supply sections parallel to the reference plane are selected at equal intervals. When the distance from the reference plane is greater than the set distance, the change amplitude of the air supply jet trajectory is reduced, and the number of selected air supply sections can be appropriately reduced, such as selecting a second set number of air supply sections parallel to the reference plane at equal intervals.

[0081] Optionally, the distance is set to 1 meter. The first set number is set to 10, and the second set number is set to 5.

[0082] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for determining the trajectory of the air supply jet, including:

[0083] S101: The processor obtains steady-state operating parameters of the air conditioner.

[0084] S102: The processor simulates the air outlet state of the air conditioner according to the steady-state operation parameters.

[0085] S103, the processor determines the maximum wind speed point of the air supply jet trajectory of the air conditioner according to the simulated air outlet state.

[0086] S114, the processor uses the maximum wind speed point as the position of the center point of the air supply jet trajectory on the corresponding air supply section.

[0087] S124, the processor determines the line connecting the maximum wind speed points on the multiple air supply cross sections as the air supply jet trajectory line.

[0088] The corresponding point with the maximum air supply speed, i.e., the maximum wind speed point, can be obtained on each air supply section. The maximum wind speed point is taken as the position of the center point of the air supply jet trajectory line on the corresponding air supply section. The maximum wind speed points of all air supply sections are connected, and the connection line is the air supply jet trajectory line.

[0089] In this way, by finding the point with the largest air velocity in the air supply jet trajectory and determining the center point position of the air supply jet trajectory on the preselected section, multiple air supply jet trajectory lines can be converted into one air supply jet trajectory line.

[0090] Combination Figure 6 As shown, the embodiment of the present disclosure provides another method for determining the trajectory of the air supply jet, including:

[0091] S101: The processor obtains steady-state operating parameters of the air conditioner.

[0092] S102: The processor simulates the air outlet state of the air conditioner according to the steady-state operation parameters.

[0093] S103, the processor determines the maximum wind speed point of the air supply jet trajectory of the air conditioner according to the simulated air outlet state.

[0094] S104: The processor determines the trajectory of the air supply jet according to the maximum wind speed point.

[0095] S105: The processor determines the temperature corresponding to the maximum wind speed point.

[0096] S106: The processor determines the lowest temperature on the air supply cross section corresponding to the maximum wind speed point.

[0097] S107, the processor compares and verifies the correctness of the air supply jet trajectory line based on the temperature corresponding to the maximum wind speed point and the lowest temperature on the air supply section.

[0098] After determining the maximum wind speed point, determine the temperature corresponding to the maximum wind speed point. Also, determine the lowest temperature on the air supply section corresponding to the maximum wind speed point. According to the temperature corresponding to the maximum wind speed point and the lowest temperature on the air supply section, verify whether the above-determined air supply jet trajectory is correct. As can be seen from the previous text, when simulating the stable operation of the air conditioner, the steady-state supply air temperature of the air conditioner is the average value of the lowest supply air temperature in each air supply cycle. Therefore, in theory, the supply air temperature on the air supply jet trajectory should be the lowest temperature corresponding to the air supply section, that is, the temperature corresponding to the maximum wind speed point is the lowest temperature. Therefore, if the error between the temperature corresponding to the maximum wind speed point and the lowest temperature on the same air supply section is less than or equal to the error threshold, the air supply jet trajectory is judged to be correct. Otherwise, the air supply jet trajectory is judged to be incorrect.

[0099] In this way, the correctness of the air supply jet trajectory can be verified by the temperature corresponding to the maximum wind speed point and the lowest temperature on the same air supply section. In addition, it can be seen that the point on the determined air supply jet trajectory is the point with the maximum air supply speed and the lowest air supply temperature.

[0100] The following takes the split cabinet single-column air conditioner as an example to specifically illustrate the application of this method:

[0101] The steady-state air supply parameters of the air conditioner in the summer cooling state are obtained by field experiments. The dimensions of the laboratory room are: 6.85 meters long, 6.75 meters wide, and 2.85 meters high. The main heat sources in the room are four lamps on the ceiling, each of which is 1.2 meters long and 0.3 meters wide. The indoor unit of the air conditioner is arranged in a corner of the laboratory, forming a diagonal with the laboratory door. The upper air outlet of the air conditioner is 0.525 meters long and 0.16 meters wide, which is a rectangular air outlet; the lower air outlet is 0.405 meters long and 0.16 meters wide, which is a rectangular air outlet; the return air outlet is 0.94 meters long and 0.34 meters wide, which is an arc air outlet.

[0102] The experiment sets up three working conditions: the air conditioner temperature is set to 21°C at high wind speed, medium wind speed and low wind speed. The plane where the air outlet of the air conditioner is located is taken as the reference plane, and four sections parallel to the reference plane are selected at 0.1m, 0.5m, 1m and 2m away from the reference plane. With the center line of the plane where the air outlet of the air conditioner is located perpendicular to the ground as a reference, a measuring line is arranged at each of the above four sections. On each measuring line, the midpoint of the lower air outlet 0.94m above the ground is selected as the bottom measuring point, the midpoint of the boundary between the upper and lower air outlets 1.11m above the ground is selected as the middle measuring point, and the midpoint of the upper air outlet 1.38m above the ground is selected as the high measuring point. The air supply temperature and air supply speed of these measuring points are measured.

[0103] Three measuring points at different heights are set at the air return outlet behind the air conditioner to measure the return air temperature. Temperature sensors are placed on the four walls, ceiling, floor, lamps, doors and windows of the laboratory to measure the indoor ambient temperature parameters.

[0104] The supply air temperature obtained from the experiment changes dynamically and periodically, such as Figure 7 As shown in the figure, the lowest average temperature of each cycle on the air supply section at 0.1 meters is taken as the air supply temperature of the air conditioner under steady-state operation. Figure 8 As shown, the average value of the fluctuating stable speed of the air supply speed on the air supply section at 0.1 m is taken as the air supply speed value under steady-state operation of the air conditioner.

[0105] The operating parameters such as the supply air temperature, supply air speed, return air temperature during steady-state air supply obtained from the experiment, as well as the measured indoor environmental parameters such as indoor temperature and wall temperature, are input into the CFD simulation software as known boundary conditions to simulate the steady-state operation of the air conditioner.

[0106] According to the CFD simulation results, the plane where the air outlet of the air conditioner is located is taken as the reference plane, and 10 air supply sections parallel to the reference plane are selected at equal intervals within 1 meter from the reference plane. In the range beyond 1 meter from the plane where the air outlet is located, an air supply section parallel to it is selected every 0.5 meters. Fig. 9 As shown in the figure, the point with the largest wind speed on each air supply section in the simulation data is identified, which represents the position of the center point of the air supply jet trajectory on each air supply section. Fig.10 As shown in the figure, the air supply temperature values ​​corresponding to the maximum air supply velocity points on the selected multiple air supply sections are verified and compared with the minimum air supply temperature on the same air supply section. If the air supply jet trajectory is correct, then in theory, the connecting line of the air supply temperature values ​​corresponding to the maximum air supply velocity points on each air supply section and the connecting line of the minimum air supply temperature on each air supply section should approach the same straight line. In this way, we can get the following: Fig.11 The air supply jet trajectory of the air conditioner shown has the highest air supply speed and the lowest air supply temperature.

[0107] Combination Fig.12 As shown, an embodiment of the present disclosure provides a device 120 for determining the trajectory of an air supply jet, comprising: an acquisition module 121, a simulation module 122, a first determination module 123, and a second determination module 124.

[0108] The device 120 for determining the trajectory of the air supply jet provided by the embodiment of the present disclosure is used to first obtain the steady-state operating parameters of the air conditioner, and simulate the steady-state air outlet of the air conditioner based on the steady-state operating parameters. Then, based on the simulation results, the maximum wind speed point of the air supply jet trajectory of the air conditioner is determined, and then the air supply jet trajectory is determined. In this way, the determination of the air supply jet trajectory of the air conditioner is achieved through the simulation analysis of the steady state of the air conditioner, which is not only applicable to air conditioners with stable jet trajectories and single air outlets, but also applicable to air conditioners with dynamic changes in air supply jets and complex and diverse air outlet forms. In this way, the maximum wind speed position can be identified for various forms of air conditioners, so as to facilitate the subsequent adjustment of the operation of the air conditioner, optimize the air supply effect of the air conditioner, efficiently exert the heat exchange effect of the air conditioner, reduce energy consumption, and improve the operating efficiency of the air conditioning system. By adjusting the air temperature and wind speed settings of the air conditioner, the air supply jet trajectory can better meet the local and overall temperature requirements of the room, thereby improving the comfort of the indoor environment and meeting the thermal comfort requirements of the user.
