[0002] With the development of air conditioning technology and the improvement of people's living standards, integrated cabinet air conditioners are widely used in life, work and industrial fields due to their compactness and flexibility. Integrated cabinet air conditioners usually contain internal and external fans, which are the core components of the system's cooling performance.

[0003] However, in the integrated cabinet air conditioners currently on the market, the internal and external fans usually use the same model of motor, and due to the variable placement of the whole machine, the differences in the installation positions (such as side, front, bottom) and installation heights of the internal and external fans, and the different thicknesses of the fan cover, the static pressure difference at the air outlet changes, causing the actual operating speed of the fan to deviate from the theoretical speed. This deviation directly affects the cooling effect of the system and the user experience.

[0004] Existing fan speed measurement mostly relies on air volume and air pressure sensors, or requires manual testing with a stroboscope, which has problems such as response lag and large errors, and cannot effectively adjust the fan speed in real time. Therefore, how to solve the fan speed deviation of air conditioning equipment has become an urgent problem to be solved. Summary of the invention

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] For the convenience of understanding the embodiments of the present invention, the following will further explain with specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation to the embodiments of the present invention.

[0046] Figure 1 The flowchart of a control method for an air conditioning device provided by an embodiment of the present invention is shown as Figure 1 shown, and the method specifically includes:

[0047] S11. Obtain the current first rotation speed of the internal fan and the current second rotation speed of the external fan of the air conditioning device. The first rotation speed is determined by detecting the fluorescent mark of the internal fan, and the second rotation speed is determined by detecting the fluorescent mark of the external fan.

[0048] The control method for the air conditioning device provided by the embodiment of the present invention is applied to an air conditioning device (for example, an integrated cabinet air conditioner). In an integrated cabinet air conditioner, the internal fan and the external fan usually adopt the same type of motor, but their installation positions (such as side placement, front placement, bottom placement) and outlet air pressure will affect their rotation speeds. To achieve accurate fan speed detection and adjustment, this solution accurately obtains the rotation speeds of the internal fan and the external fan by detecting the fluorescent marks, and controls the internal fan and the external fan according to the obtained rotation speeds and the target rotation speed.

[0049] In this embodiment, a section of special fluorescent mark (such as a highly reflective fluorescent tape or paint) is evenly pasted on the edge of the internal fan motor shaft or the motor housing as a detection point (the position of the detection point can be set according to requirements, and this embodiment does not make specific limitations). An optoelectronic sensor (which can adopt a laser sensor, a reflective sensor, etc.) is installed at the corresponding position of the internal fan to irradiate the fluorescent mark and receive its reflected light signal. The optoelectronic sensor emits a light beam. When the motor rotates and drives the fluorescent mark to pass through the sensor irradiation area, the reflected light signal will be received by the sensor. The detection system records the fluorescent reflected light signal received once as "detected 1 time", and two consecutive received reflected light signals indicate that the fan rotates 1 circle. Thus, the first rotation speed of the internal fan can be determined by obtaining the number of rotations of the fan within a period of time.

[0050] Similarly, a fluorescent mark is set on the edge of the external fan motor shaft or the motor housing. An optoelectronic sensor is installed at the corresponding position of the external fan to emit a light beam to irradiate the fluorescent mark. The reflected light of the fluorescent mark is detected, and the steps are similar to those of the internal fan. Within the same time period, the number of times of the received fluorescent signals is counted, and then the number of rotations of the external fan is determined. Thus, the second rotation speed of the external fan can be determined by obtaining the number of rotations of the external fan within a period of time.

[0051] Transmit the first rotation speed of the internal fan and the second rotation speed of the external fan to the main control system (such as a PLC or an embedded controller) in real time.

[0052] S12. Obtain the first target speed of the internal fan and the second target speed of the external fan.

[0053] In this embodiment, the target speed refers to the ideal speed preset by the system for the internal fan and the external fan, which is usually determined based on comprehensive factors such as system load (temperature, humidity), heat dissipation requirements, environmental conditions, and the specific configuration of the cabinet. It is also possible to directly obtain parameters such as the temperature and wind speed of the air conditioning equipment set by the current user, and determine the first target speed and the second target speed corresponding to the set parameters of the current user.

[0054] In a possible implementation manner, when obtaining the target speed according to the system load demand, the main control system (such as an air conditioner controller or a PLC) calculates the required cooling capacity based on the currently collected sensor data such as temperature, humidity, and pressure difference; calculates the required air volume according to the cooling capacity demand, the outlet area of the internal fan, and the designed wind speed curve; and inversely calculates the required first target speed according to the air volume and the performance curve of the internal fan (the speed-air volume characteristic obtained through experimental calibration).

[0055] If the system is connected to the central air conditioning management platform, the target speed can be directly issued by the platform and dynamically adjusted according to the global strategy (such as energy-saving mode, cooling mode, dehumidification mode).

[0056] The second target speed of the external fan can be obtained according to the outdoor environmental conditions. For example, detect the current outdoor temperature, humidity, and wind speed (obtained through an external sensor or a meteorological interface), calculate the required heat dissipation air volume of the external fan according to the heat dissipation requirements; and inversely calculate the required speed in combination with the performance curve of the external fan (the speed-air volume relationship).

[0057] S13. Control the internal fan and the external fan according to the first speed, the second speed, the first target speed, and the second target speed.

[0058] In this embodiment, calculate the speed deviation. The internal fan deviation is equal to the first target speed minus the first speed, and the external fan deviation is equal to the second target speed minus the second speed. Adjust the fan drive signal (such as PWM duty cycle, voltage frequency, etc.) according to the deviation to make the actual speed as close as possible to the target speed.

[0059] When controlling the internal fan, if the first target speed is higher than the first speed, increase the internal fan drive signal (increase the PWM duty cycle / frequency) to accelerate; otherwise, decrease the internal fan drive signal to decelerate; when within the allowable error range, maintain the current state and enter the steady-state regulation.

[0060] When controlling the external fan, if the second target speed is higher than the second speed, increase the external fan drive signal to increase the speed; otherwise, reduce the drive signal to decelerate; when within the allowable error range, maintain the current drive to maintain a steady state. If the internal fan speed reaches the limit, the external fan speed can be appropriately increased to assist in heat dissipation; if the external fan speed reaches the limit, the internal fan speed can be appropriately increased to enhance circulation. At the same time, continuously monitor the speed change, continuously update the control output, and form a closed-loop control system; the target speed can also be dynamically adjusted in combination with the system load change.

[0061] The control method of the air conditioning equipment provided by the embodiment of the present invention includes obtaining the current first speed of the internal fan and the current second speed of the external fan of the air conditioning equipment, where the first speed is determined by detecting the fluorescent marker of the internal fan, and the second speed is determined by detecting the fluorescent marker of the external fan; obtaining the first target speed of the internal fan and the second target speed of the external fan; and controlling the internal fan and the external fan according to the first speed, the second speed, the first target speed, and the second target speed. Thus, the speeds of the internal fan and the external fan can be accurately obtained by detecting the fluorescent marker, and the internal fan and the external fan can be controlled according to the obtained speeds and target speeds, effectively solving the problem of the fan speed deviation of the air conditioning equipment and ensuring the system operation efficiency and refrigeration effect.

[0062] Figure 2 It is a schematic flowchart of another control method of the air conditioning equipment provided by the embodiment of the present invention, as Figure 2 shown, and the method specifically includes:

[0063] S21. Detect the fluorescent marker of the internal fan motor through the photoelectric sensor on the internal fan cover plate, and detect the fluorescent marker of the external fan motor through the photoelectric sensor on the external fan cover plate; determine the first speed according to the number of reflections of the fluorescent marker of the internal fan detected within the first preset time period, and determine the second speed according to the number of reflections of the fluorescent marker of the external fan detected within the first preset time period.

[0064] In this embodiment, as Figure 3 shown is a schematic structural diagram of a fan provided by the embodiment of the present invention, as Figure 4The following is a schematic structural diagram of a fan cover provided by an embodiment of the present invention. The fluorescent mark is located at the edge of the motor housing of the fan. There is a layer of cover on the fan of the whole cabinet. An optoelectronic sensor is installed on the cover to detect the fluorescent mark. An optoelectronic sensor (including a light source and a receiver) is installed on the inner fan cover. When the inner fan rotates, the fluorescent mark periodically passes through the detection range of the sensor; the optoelectronic sensor emits light to irradiate the motor. When the light encounters the fluorescent mark, the fluorescence will be reflected back to the sensor receiver, which is recorded as 1 detection signal. Within the set first preset time period T1 (for example, 60 seconds), record the number of reflections N1 of the fluorescent mark detected by the sensor; each time the fluorescent mark passes by, it is regarded as the motor rotating one circle. Due to possible errors, (N1 - 1) calculated within 1 minute is the first rotational speed of the inner fan.

[0065] Similarly, a fluorescent mark is also pasted on the shaft (or edge) of the outer fan motor; an optoelectronic sensor is installed on the outer fan cover. When the outer fan rotates, the fluorescent mark periodically passes through the detection range of the sensor; within the set first preset time period T1 (which can be the same as that of the inner fan), record the number of reflections N2 of the fluorescent mark; each time the fluorescent mark passes by, it is regarded as the motor rotating one circle. Due to possible errors, (N2 - 1) calculated within 1 minute is the second rotational speed of the outer fan.

[0066] S22. Obtain the first target rotational speed of the inner fan and the second target rotational speed of the outer fan.

[0067] In this embodiment, similar to step S12, specifically, reference can be made to Figure 1 the relevant content. For the sake of concise description, it will not be elaborated here.

[0068] S23. When the first target rotational speed is greater than or equal to the first rotational speed and the first target rotational speed has not reached the maximum rotational speed, control the rotational speed of the inner fan to increase according to the difference between the first target rotational speed and the first rotational speed; when the first target rotational speed is greater than the first rotational speed and the first target rotational speed has reached the maximum rotational speed, control the rotational speed of the outer fan to increase according to the difference between the first target rotational speed and the first rotational speed.

[0069] In this embodiment, when the target rotational speed of the inner fan is higher than the actual rotational speed and has not reached the maximum rotational speed, the inner fan will accelerate by itself; when the target rotational speed of the inner fan is higher than the actual rotational speed and the target rotational speed has reached the maximum rotational speed, the outer fan will increase its rotational speed to assist in refrigeration.

[0070] Specifically, compare the actually detected first rotational speed of the internal blower with the first target rotational speed. When the first target rotational speed is greater than or equal to the first rotational speed and the target rotational speed has not reached the maximum rotational speed specified by the system, the system calculates the difference between the first target rotational speed and the first rotational speed. Based on this difference, control the internal blower to increase its rotational speed to gradually approach or reach the set target rotational speed. The increased rotational speed is positively correlated with the difference.

[0071] If the first target rotational speed of the internal blower is greater than the actually detected first rotational speed of the internal blower, but the first target rotational speed of the internal blower has reached the maximum rotational speed allowed by the system, this indicates that the internal blower cannot meet the refrigeration demand even when running at full speed. At this time, the system controls the external blower to increase its rotational speed based on the difference between the first target rotational speed and the actually detected first rotational speed of the internal blower. The increased rotational speed is positively correlated with the difference to enhance the heat dissipation efficiency of the outdoor heat exchanger, thereby improving the refrigeration capacity of the entire system. Thus, the stability and refrigeration performance of the entire system can be enhanced, and the user experience can be avoided from being affected due to the limited operation of the blower.

[0072] S24. When the second target rotational speed is greater than or equal to the second rotational speed and the second target rotational speed has not reached the maximum rotational speed, control the rotational speed of the external blower to increase according to the difference between the second target rotational speed and the second rotational speed; when the second target rotational speed is greater than the second rotational speed and the second target rotational speed has reached the maximum rotational speed, control the rotational speed of the internal blower to increase according to the difference between the second target rotational speed and the second rotational speed.

[0073] In this embodiment, if the second target rotational speed of the external blower is greater than or equal to the currently actually detected second rotational speed and the second target rotational speed has not reached the maximum rotational speed allowed by the system, it means that there is still room for the external blower to increase. The system calculates the difference between the second target rotational speed and the second rotational speed. Based on this difference, control the external blower to increase its rotational speed to gradually approach or reach the set target rotational speed. The increased rotational speed is positively correlated with the difference.

[0074] If the second target rotational speed is greater than the second rotational speed, but the second target rotational speed has reached the maximum rotational speed allowed by the system, this indicates that the external blower cannot meet the refrigeration demand even when running at full speed. At this time, the system controls the internal blower to increase its rotational speed based on the difference between the second target rotational speed and the second rotational speed. The increased rotational speed is positively correlated with the difference to enhance the heat dissipation efficiency of the outdoor heat exchanger, thereby improving the refrigeration capacity of the entire system. Thus, the stability and refrigeration performance of the entire system can be enhanced, and the user experience can be avoided from being affected due to the limited operation of the blower.

[0075] In a possible implementation manner, when the rotational speeds of both the internal blower and the external blower reach the maximum rotational speed, control the running duration of the internal blower and the external blower to increase; when the running duration reaches the second preset duration, generate a prompt message for display.

[0076] Specifically, when both the internal and external fans of the system have reached their maximum allowable speeds (i.e., it is no longer possible to further increase the air volume or heat exchange capacity), and the cooling demand is still not fully met, it is necessary to increase the operating duration of the internal and external fans (to make up for the insufficient heat exchange by extending the operating time); generate a prompt message (to inform the maintenance personnel or user that the system has reached its limit operation and may require adjusting the environment or maintaining the equipment). When increasing the operating duration, define a current operating duration (T0) that starts counting after both the internal and external fans reach their maximum values, and a second preset duration (T2) for triggering the prompt; when it is detected that both the internal and external fans have reached their maximum speeds, detect whether the current operating duration has reached the second preset duration. If so, generate a prompt message, such as: "The internal and external fans have been running at their maximum speeds continuously for more than the preset duration. Please check the system environment, filter, or heat dissipation conditions." This prompt can be sent in text form to the control system display screen, user mobile APP, background management system, etc. If the internal and external fans do not reach their maximum speeds simultaneously, no judgment is made; to avoid false triggering, it can be defined that the operating duration is considered to meet the standard only when multiple consecutive detections all meet the conditions, improving the system stability. The system can additionally record logs for the convenience of later maintenance personnel to view.

[0077] In this embodiment, when the difference between the indoor temperature and the target temperature is less than the first threshold, and the indoor humidity is greater than the second threshold, control the internal fan to increase its speed; when the outdoor humidity is greater than the third threshold, control the external fan to decrease its speed; when the outdoor humidity is less than the fourth threshold, control the external fan to increase its speed, and the fourth threshold is less than the third threshold.

[0078] Specifically, the indoor temperature is already close to the set target temperature, indicating that the temperature adjustment demand is weakening; however, the indoor humidity is relatively high, which may cause discomfort or the risk of mildew; increase the speed of the internal fan to increase air circulation and dehumidification efficiency, and accelerate the discharge of moisture; at the same time, avoid excessive cooling to improve comfort.

[0079] If the outdoor humidity is too high, it means that introducing outdoor air will increase the humidity burden; at this time, reduce the speed of the external fan to reduce the entry of high-humidity outdoor air and relieve the system's dehumidification pressure. When the outdoor humidity is relatively low, introducing external air helps to reduce the indoor humidity; increase the speed of the external fan to increase the fresh air volume, helping to adjust the indoor humidity and improve the air quality.

[0080] In a possible implementation, obtain the humidity information of multiple indoor areas; determine the air outlet angle, air outlet duration, and fan speed of the corresponding air conditioning equipment for each area according to the multiple humidity information; control the air conditioning equipment according to the air outlet angle, and control the internal fan according to the air outlet duration and fan speed.

[0081] Specifically, humidity data of different areas in the room are collected in real time through humidity sensors arranged in different areas of the room; the collected data is transmitted to the central control unit for processing. According to the humidity values of different areas, the corresponding air outlet angle (the angle for adjusting the wind direction) and wind direction adjustment angle are calculated or obtained by looking up a table to ensure that the air flow is accurately delivered to the area with abnormal humidity; the air outlet duration (the continuous blowing time) is adjusted, and the blowing duration is extended for the area with relatively high humidity; the fan speed (the air volume) is adjusted, and the fan speed in the area with high humidity is correspondingly increased to promote the discharge of moisture. The wind direction adjustment mechanism (such as an adjustable air outlet or a guiding vane) in the control device is controlled to adjust the air outlet angle and accurately send the air to the specified area. According to the calculated air outlet duration and fan speed, the start and stop times of the internal fan and the fan speed are controlled; the operating parameters of the fan are dynamically adjusted to strengthen ventilation in the area with relatively high humidity and reduce the humidity. The partition differential air supply control based on multi-area humidity data is realized, and by adjusting the air outlet angle, air outlet duration and fan speed, the accuracy of humidity adjustment and the energy efficiency performance of the air conditioning equipment are effectively improved.

[0082] The control method of the air conditioning equipment provided by the embodiment of the present invention uses a fluorescent mark as the starting point of the motor, and the actual speed of the fan is measured by irradiating the fluorescent mark with a photoelectric sensor. According to the speed difference between the actual speed and the target speed and the influence of the maximum speed on the refrigerating capacity, the speeds of the internal fan and the external fan are adjusted to ensure that the refrigeration system is always in the best working state and improve the user experience.

[0083] As an example, Figure 5 is a schematic flow chart of another control method of the air conditioning equipment provided by the embodiment of the present invention. As shown in Figure 5 it, the method specifically includes:

[0084] Step 1: Under ideal environmental conditions, the rotation speed table Vs of the fan under standard atmospheric pressure is obtained through experiments, and the range is 0 - Vsmax (revolutions per minute);

[0085] Step 2: A fluorescent mark is marked on the edge of the motor of each fan. When the fan starts, the photoelectric sensor irradiates the fluorescent mark on the motor, and the light reflected back by the fluorescent mark is recorded as 1 time. The two times of light reflected back by the fluorescent mark are recorded as 1 circle. The (N - 1) calculated within 1 minute is the fan speed, and the actual speeds Vin and Vout of the internal fan and the external fan are respectively obtained;

[0086] Step 3: Set the target speed Vsin of the internal fan, and set the speed difference △Vin = |Vsin - Vin| between the set speed and the actual speed. If Vsin ≥ Vin, the internal fan increases the speed by △Vin. If Vsin < Vin, the internal fan decreases the speed by △Vin;

[0087] Step 4: Set the target speed Vsout of the external fan. Set the difference between the set speed and the actual speed ΔVout = |Vsout - Vout|. If Vsout ≥ Vout, the external fan increases the speed by ΔVout. If Vsout < Vout, the external fan decreases the speed by ΔVout;

[0088] Step 5: If the target speed Vsin of the internal fan is the maximum speed Vsmax and Vsin > Vin, and the internal fan cannot reach the maximum speed under standard conditions, increasing the speed of the external fan can improve the heat dissipation efficiency of the outdoor heat exchanger, thereby enhancing the refrigeration capacity of the entire system;

[0089] Step 6: If the target speed Vsout of the external fan is the maximum speed Vsmax and Vsout > Vout, and the external fan cannot reach the maximum speed under standard conditions, increasing the speed of the internal fan can accelerate the circulation of indoor air, thereby enhancing the refrigeration capacity of the entire system;

[0090] Step 7: If neither the internal fan nor the external fan can reach the maximum speed under standard conditions, Vsin > Vin and Vsout > Vout, then it is necessary to extend the operation time of the actual maximum speeds of the internal fan and the external fan until the refrigeration system stabilizes;

[0091] Step 8: If neither the internal fan nor the external fan can reach the maximum speed under standard conditions, and situations such as too high indoor temperature and the refrigeration system not meeting the standards for a long time occur, an alarm is sent to remind the debugging personnel.
