Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air conditioner operation control method, device, air conditioner system and readable storage medium. Background Art

[0002] With the progress of society and the improvement of people's living standards, the popularity rate of air conditioners is getting higher and higher. In cold winters or hot summers, air conditioners are needed to improve the temperature environment.

[0003] The highest rotational speed of the blower in the existing air conditioner air supply system is often determined in combination with the most severe working conditions and the maximum load of the whole machine during actual operation. After the highest rotational speed is determined, the motor can only operate within the highest rotational speed range and cannot achieve overspeed operation.

[0004] However, the above method is likely to cause the inability of the air conditioner to self-regulate the highest rotational speed of the motor according to its actual load working conditions after leaving the factory. When the load of the motor operating condition is inconsistent with the load of the test condition, the motor speed cannot be further increased to further increase the air volume of the blower, resulting in the inability to fully exert the potential of the motor or the inability to reduce the highest rotational speed of the motor to avoid long-term overload operation of the motor, which affects the service life of the motor. Summary of the Invention

[0005] The present invention provides an air conditioner operation control method, device, air conditioner system and readable storage medium to solve the defect in the prior art that the highest rotational speed of the motor in the existing air supply system cannot achieve overspeed operation after being set, so that the highest rotational speed of the motor cannot be self-regulated according to the actual load working conditions, enabling the blower to dynamically adjust the highest rotational speed of the motor according to the actual load working conditions and quickly meet the user's temperature control requirements.

[0006] The present invention provides an air conditioner operation control method, including: obtaining the temperature of the heat exchanger arranged on the air flow channel of the blower and the ambient temperature of the blower; comparing the temperature of the heat exchanger with the ambient temperature, and determining whether to adjust the highest operating rotational speed of the blower according to the comparison result and the previously obtained air conditioner operation mode; wherein, the blower operates at the previously determined highest operating rotational speed; if it is determined to adjust the highest operating rotational speed of the blower, then adjust the highest operating rotational speed of the blower according to the temperature of the heat exchanger, the ambient temperature and the previously obtained load condition, and control the blower to operate at the adjusted highest operating rotational speed; otherwise, maintain the highest operating rotational speed of the blower and control the blower to continue to operate at the highest operating rotational speed.

[0007] It should be noted that the temperature of the heat exchanger and the ambient temperature of the fan are obtained, and based on this, the two are compared, and combined with the air conditioner operation mode to determine whether to adjust the maximum operating speed of the fan. Considering various actual situations to accurately judge the maximum speed of the fan helps to make the operating state of the fan better adapt to the overall operating requirements of the current air conditioner system. Further, according to the heat exchanger temperature, ambient temperature and load conditions, the maximum operating speed of the fan is jointly adjusted to ensure the maximization of the air conditioner operation efficiency, so as to quickly meet the user's temperature control requirements, rapidly cool or heat the room, and improve the comfort level.

[0008] According to the present invention, an air conditioner operation control method is provided. According to the comparison result and the previously obtained air conditioner operation mode, it is determined whether to adjust the maximum operating speed of the fan, including: based on the air conditioner operation mode being the cooling mode, determining whether the heat exchanger temperature is higher than the ambient temperature. If the heat exchanger temperature is higher than the ambient temperature, it is determined not to adjust the maximum operating speed of the fan; otherwise, it is determined to adjust the maximum operating speed of the fan; based on the air conditioner operation mode being the heating mode, determining whether the heat exchanger temperature is lower than the ambient temperature. If the heat exchanger temperature is lower than the ambient temperature, it is determined not to adjust the maximum operating speed of the fan; otherwise, it is determined to adjust the maximum operating speed of the fan.

[0009] It should be noted that in the cooling mode, by determining whether the temperature of the heat exchanger arranged on the air flow channel of the fan is higher than the corresponding ambient temperature, so that when the heat exchanger temperature is higher than the corresponding ambient temperature, the heat can be effectively transferred from the room or the interior of the air conditioner system to the environment. At this time, continuing to control the fan to operate at the maximum operating speed can ensure the maximum enhancement of air convection, accelerate the heat exchange process, and improve the cooling efficiency. And when the heat exchanger temperature is not higher than the corresponding ambient temperature, by adjusting the maximum operating speed, it is possible to avoid the fan running at a low efficiency or in an overloaded state for a long time, thereby reducing additional energy waste and enabling the air conditioner to achieve energy-saving operation while efficiently cooling.

[0010] In addition, in the heating mode, by determining whether the temperature of the heat exchanger arranged on the corresponding air flow channel of the fan is lower than the corresponding ambient temperature, so that when the heat exchanger temperature is lower than the corresponding ambient temperature, the heat can be effectively transferred from the environment to the heat exchanger. At this time, keeping the fan running at the maximum operating speed can accelerate the heat exchange process between the air and the heat exchanger, increase the rising speed of the indoor temperature. And when the heat exchanger temperature is not lower than the corresponding ambient temperature, by adjusting the fan speed, to keep the fan running at a high speed when the heat exchanger temperature is lower than the ambient temperature, ensuring a better heating effect under the same energy consumption, avoiding energy waste, and making the air conditioner more energy-saving and efficient during the heating process.

[0011] An air conditioner operation control method provided by the present invention adjusts the maximum operating speed of a blower according to the heat exchanger temperature, the ambient temperature, and the previously obtained load condition, and includes: obtaining a recommended speed according to the heat exchanger temperature, the ambient temperature, and the previously obtained blower load condition; and adjusting the maximum operating speed of the blower according to the recommended speed.

[0012] It should be noted that by comprehensively considering various factors such as the load condition, the heat exchanger temperature, and the ambient temperature to determine the recommended speed, the speed of the blower can be accurately matched with the actual operating requirements of the current air conditioner equipment, so as to ensure that the air conditioner equipment can operate at the most suitable blower speed under various different working conditions, improve the overall operating efficiency of the air conditioner equipment, make the refrigeration or heating effect reach the best state, and at the same time reduce energy waste.

[0013] An air conditioner operation control method provided by the present invention adjusts the maximum operating speed of a blower according to the recommended speed, and includes: determining whether the recommended speed exceeds the target speed, and if it exceeds, adjusting the corresponding maximum operating speed according to the target speed; wherein, the target speed is determined based on the limit current, and the limit current is determined based on the rated current of the blower motor; otherwise, adjusting the corresponding maximum operating speed according to the recommended speed.

[0014] It should be noted that by controlling the blower speed not to exceed the target speed, it is ensured that the blower operates within a safe speed range, avoiding problems such as blade deformation and fracture caused by too high a speed of the blower, and at the same time avoiding increasing the load on the motor, avoiding overheating and even burning of the motor, prolonging the service life of the blower, reducing the cost of equipment maintenance and replacement, and ensuring the stable operation of the air conditioning system.

[0015] An air conditioner operation control method provided by the present invention, the fan includes an outdoor fan. After controlling the fan to operate at the highest operating speed or the adjusted highest operating speed, it includes: monitoring the air conditioner operation mode, and based on the air conditioner operation mode being the strong operation mode, adjusting the speed of the outdoor fan according to the target speed and recording the operation time; wherein, the strong operation mode is used to represent the air conditioner working mode that operates with the maximum cooling or heating capacity, the target speed is determined based on the limit current, and the limit current is determined based on the rated current of the fan motor; based on the operation time reaching the preset time threshold, according to the strong operation mode, combined with the preset cooling control strategy, controlling the heat exchanger arranged on the air flow channel of the outdoor fan to refrigerate to cool down the motor and the electronic control system of the outdoor fan; or, monitoring the air conditioner operation mode, and based on the air conditioner operation mode being the strong operation mode, monitoring the temperature of the motor winding of the outdoor fan; wherein, the strong operation mode is used to represent the air conditioner working mode that operates with the maximum cooling or heating capacity; based on the motor winding temperature exceeding the first preset temperature threshold, according to the strong operation mode, combined with the preset cooling control strategy, controlling the heat exchanger arranged on the air flow channel of the outdoor fan to refrigerate to cool down the motor and the electronic control system of the outdoor fan; or, monitoring the air conditioner operation mode, and based on the air conditioner operation mode being the strong operation mode, monitoring the temperature of the electronic control system of the outdoor unit; wherein, the strong operation mode is used to represent the air conditioner working mode that operates with the maximum cooling or heating capacity; based on the temperature of the electronic control system exceeding the second preset temperature threshold, according to the strong operation mode, combined with the preset cooling control strategy, controlling the heat exchanger arranged on the air flow channel of the outdoor fan to refrigerate to cool down the motor and the electronic control system of the outdoor fan.

[0016] It should be noted that after entering the strong operation mode, the speed of the outdoor fan is adjusted to the target speed determined based on the limit current, and the operation time is recorded to trigger the cooling mechanism when the recorded operation time reaches the preset time threshold, or, by monitoring the temperature of the motor winding in real time to trigger the cooling mechanism when the temperature exceeds the first preset temperature threshold and taking timely cooling measures, or, by monitoring the temperature of the electronic control system in real time to trigger the cooling mechanism when the temperature exceeds the second preset temperature threshold and taking timely cooling measures. By fully considering the tendency to trigger cooling based on the operation time, the temperature of the motor winding or the temperature of the electronic control system, it ensures that the outdoor fan and its associated motor and electronic control system are always in a relatively safe temperature range; in addition, according to the strong operation mode, combined with the preset cooling control strategy, to accurately control the heat exchanger on the air flow channel of the outdoor fan to refrigerate and absorb the heat generated by the motor and the electronic control system, effectively preventing equipment failures caused by overheating, ensuring the stable operation of the equipment during strong operation, reducing the number of shutdown and maintenance times caused by equipment failures, extending the service life of the equipment, and providing continuous and reliable air conditioner services for users.

[0017] An air conditioner operation control method provided by the present invention, the blower further includes an indoor blower. According to the strong operation mode and in combination with a preset cooling control strategy, the heat exchanger disposed on the air flow channel of the outdoor blower is controlled to refrigerate, so as to cool the motor and the electronic control system of the outdoor blower, including: based on the strong operation mode being the strong cooling mode, determining that the preset cooling control strategy is to control the indoor blower to stop running, control the outdoor blower to run at a reduced speed according to the previously determined optimal heat dissipation speed, and control the state switching of the outdoor unit four-way valve; based on the strong operation mode being the strong heating mode, determining that the preset cooling control strategy is to control the outdoor blower to run at a reduced speed according to the previously determined optimal heat dissipation speed; executing corresponding control according to the determined preset cooling control strategy to control the heat exchanger disposed on the air flow channel of the outdoor blower to refrigerate and cool the motor and the electronic control system of the outdoor blower.

[0018] It should be noted that when the strong operation mode is the strong cooling mode, controlling the indoor blower to stop running to reduce unnecessary energy consumption, controlling the outdoor blower to run at a reduced speed according to the optimal heat dissipation speed to avoid excessive energy consumption caused by the high-speed operation of the blower, and at the same time ensuring that sufficient air flow passes through the heat exchanger to achieve effective refrigeration and cooling, so that the refrigeration resources are concentrated on the cooling requirements of key outdoor equipment, improving the energy utilization efficiency of the entire air conditioner system in the strong cooling mode, and controlling the state switching of the outdoor unit four-way valve to change the flow direction of the refrigerant, so that the heat exchanger of the outdoor unit acts as an evaporator. When the refrigerant flows through the heat exchanger of the outdoor unit, it will absorb heat from the surrounding environment (including the motor and the electronic control system), thereby reducing the temperature of the motor and the electronic control system.

[0019] According to an air conditioner operation control method provided by the present invention, after cooling the heat exchanger disposed on the air flow channel of the outdoor fan according to the strong operation mode and in combination with a preset cooling control strategy to cool the motor and the electronic control system of the outdoor fan, it includes: determining whether the temperature of the motor of the outdoor fan reaches a first preset temperature, and determining whether the temperature of the electronic control system reaches a second preset temperature; based on the temperature of the motor of the outdoor fan reaching the first preset temperature and the temperature of the electronic control system reaching the second preset temperature, determining whether the air conditioner usage requirement is completed, and based on the completion situation of the requirement, determining whether to exit the strong operation mode; if the air conditioner usage requirement is completed, determining to exit the strong operation mode; otherwise, readjusting the rotation speed of the outdoor fan to a target speed determined based on the limit current, and updating the operation time, so that based on the updated operation time reaching a preset time threshold, cooling the heat exchanger disposed on the air flow channel of the outdoor fan according to the corresponding strong operation mode and in combination with the preset cooling control strategy to cool the motor and the electronic control system of the outdoor fan; based on the temperature of the motor of the outdoor fan not reaching the first preset temperature, and / or based on the temperature of the electronic control system not reaching the second preset temperature, continuing to cool the heat exchanger disposed on the air flow channel of the outdoor fan according to the corresponding strong operation mode and in combination with the preset cooling control strategy to cool the motor and the electronic control system of the outdoor fan until the temperature of the motor of the outdoor fan reaches the first preset temperature and the temperature of the electronic control system reaches the second preset temperature.

[0020] It should be noted that by real-time monitoring the temperature of the outdoor fan motor and the temperature of the electronic control system and comparing them with the corresponding preset temperatures respectively to determine whether the motor temperature and the electronic control system temperature are reduced to the corresponding preset temperatures, thereby dynamically adjusting the cooling strategy according to the real-time feedback of the motor temperature and the electronic control system temperature to ensure that the motor and the electronic control system are cooled to the corresponding preset temperatures and maintain the stable output of the overall performance of the air conditioner system; in addition, after the motor temperature and the electronic control system temperature are reduced to the corresponding preset temperatures, further determine whether to exit the strong operation mode, so as to accurately adjust the operation mode according to the actual temperature state on the premise of ensuring the safe operation of the equipment, avoid excessive energy consumption when the strong operation mode is not required, and achieve the perfect coordination of intelligent energy saving and operation mode.

[0021] The present invention also provides an air conditioner operation control device, including: a temperature acquisition module for acquiring the temperature of a heat exchanger disposed on an air flow passage of a blower and the ambient temperature of the blower; a rotation speed judgment module for comparing the temperature of the heat exchanger and the ambient temperature, and determining whether to adjust the maximum operating rotation speed of the blower according to the comparison result and the previously acquired air conditioner operation mode; wherein, the blower operates at the previously determined maximum operating rotation speed; a rotation speed adjustment module for, if it is determined to adjust the maximum operating rotation speed of the blower, adjusting the maximum operating rotation speed of the blower according to the temperature of the heat exchanger, the ambient temperature and the previously acquired load condition, and controlling the blower to operate at the adjusted maximum operating rotation speed; otherwise, maintaining the maximum operating rotation speed of the blower and controlling the blower to continue to operate at the maximum operating rotation speed.

[0022] It should be noted that the temperature acquisition module acquires the temperature of the heat exchanger and the ambient temperature of the blower, so as to use the rotation speed judgment module to compare the two on this basis, and combine the air conditioner operation mode to determine whether to adjust the maximum operating rotation speed of the blower, so as to accurately judge whether it is the maximum rotation speed of the blower by integrating various actual situations, which helps to make the operating state of the blower better adapt to the overall operation requirements of the current air conditioner system, and further adjusts the maximum operating rotation speed of the blower jointly by the rotation speed adjustment module according to the temperature of the heat exchanger, the ambient temperature and the load condition, so that the blower dynamically adjusts the maximum rotation speed of the motor operation according to the actual load condition, ensuring the maximization of the air conditioner operation efficiency, thereby quickly meeting the user's temperature control requirements, quickly cooling or heating the room, and improving the comfort level.

[0027] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in 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 in the present invention without making creative efforts fall within the scope of protection of the present invention.

[0028] The following combines Figure 1 Describe the flow schematic diagram of an air-conditioning operation control method of the present invention. The method includes: S11. Obtain the temperature of the heat exchanger provided on the air flow channel of the fan and the ambient temperature of the fan; S12. Compare the temperature of the heat exchanger and the ambient temperature, and determine whether to adjust the maximum operating speed of the fan according to the comparison result and the previously obtained air-conditioning operation mode; wherein, the fan operates at the previously determined maximum operating speed; S13. If it is determined to adjust the maximum operating speed of the fan, then adjust the maximum operating speed of the fan according to the temperature of the heat exchanger, the ambient temperature and the previously obtained load condition, and control the fan to operate at the adjusted maximum operating speed; otherwise, maintain the maximum operating speed of the fan and control the fan to continue to operate at the maximum operating speed.

[0029] It should be noted that the step numbers "S1N" in this specification do not represent the sequence of the air-conditioning operation control method. The following specifically combines Figure 2 Describe the air-conditioning operation control method of the present invention.

[0030] Step S11. Obtain the temperature of the heat exchanger provided on the air flow channel of the fan and the ambient temperature of the fan.

[0031] It should be added that the fan includes all indoor fans and outdoor fans involved in the air-conditioning equipment. For example, if the air-conditioning equipment includes an indoor unit and at least one indoor unit, then the fan includes an outdoor fan and at least one indoor fan. By respectively executing steps S11-step S13 for the indoor fan and the outdoor unit fan, the maximum operating speed of the corresponding fan is adjusted to avoid problems such as long-term overloading operation of the motor caused by the situation that the maximum operating speed of the motor cannot be self-adjusted according to the actual load condition.

[0032] In addition, whether it is an indoor fan or an outdoor fan, the fan includes a fan and a motor. The heat exchanger is disposed on the air flow channel of the fan and can be disposed on one side or around the fan so that the air supply volume first passes through the heat exchanger and then through the motor. Correspondingly, the ambient temperature can be obtained based on detecting the ambient temperature around the motor.

[0033] Step S12: Compare the heat exchanger temperature with the ambient temperature, and determine whether to adjust the maximum operating speed of the fan according to the comparison result and the previously obtained air conditioner operating mode; wherein, the fan operates at the previously determined maximum operating speed.

[0034] In this embodiment, determining whether to adjust the maximum operating speed of the fan according to the comparison result and the previously obtained air conditioner operating mode includes: based on the air conditioner operating mode being the cooling mode, determining whether the heat exchanger temperature is higher than the ambient temperature. If the heat exchanger temperature is higher than the ambient temperature, it is determined not to adjust the maximum operating speed of the fan; otherwise, it is determined to adjust the maximum operating speed of the fan; based on the air conditioner operating mode being the heating mode, determining whether the heat exchanger temperature is lower than the ambient temperature. If the heat exchanger temperature is lower than the ambient temperature, it is determined not to adjust the maximum operating speed of the fan; otherwise, it is determined to adjust the maximum operating speed of the fan.

[0035] It should be noted that in the cooling mode, by determining whether the temperature of the heat exchanger disposed on the air flow channel of the fan is higher than the corresponding ambient temperature, when the temperature of the heat exchanger is higher than the corresponding ambient temperature, the heat can be effectively transferred from the indoor or the interior of the air conditioner system to the environment. At this time, continuing to control the fan to operate at the maximum operating speed can ensure the maximum enhancement of air convection, accelerate the heat exchange process, improve the cooling efficiency, and when the temperature of the heat exchanger is not higher than the corresponding ambient temperature, by adjusting the maximum operating speed, it is possible to avoid the fan from operating in an inefficient or overloaded state for a long time, thereby reducing additional energy waste and enabling the air conditioner to achieve energy-saving operation while efficiently cooling.

[0036] In addition, in the heating mode, by determining whether the temperature of the heat exchanger disposed on the corresponding air flow channel of the fan is lower than the corresponding ambient temperature, when the temperature of the heat exchanger is lower than the corresponding ambient temperature, the heat can be effectively transferred from the environment to the heat exchanger. At this time, keeping the fan running at the maximum operating speed can accelerate the heat exchange process between the air and the heat exchanger, increase the speed of the indoor temperature rise, and when the temperature of the heat exchanger is not lower than the corresponding ambient temperature, by adjusting the fan speed, to keep the fan running at a high speed when the temperature of the heat exchanger is lower than the ambient temperature, ensuring a better heating effect under the same energy consumption, avoiding energy waste, and making the air conditioner more energy-efficient and efficient during the heating process.

[0037] It should be added that the maximum operating speed corresponding to the fan is previously determined based on the most severe working conditions and the maximum load during the actual operation of the air conditioner equipment.

[0038] In step S13, if it is determined to adjust the maximum operating speed of the blower, then adjust the maximum operating speed of the blower according to the heat exchanger temperature, the ambient temperature, and the previously obtained load condition, and control the blower to operate at the adjusted maximum operating speed; otherwise, maintain the maximum operating speed of the blower and control the blower to continue operating at the maximum operating speed.

[0039] In this embodiment, adjusting the maximum operating speed of the blower according to the heat exchanger temperature, the ambient temperature, and the previously obtained load condition includes: obtaining a recommended speed according to the heat exchanger temperature, the ambient temperature, and the previously obtained blower load condition; and adjusting the maximum operating speed of the blower according to the recommended speed.

[0040] It should be noted that by comprehensively considering various factors such as the load condition, the heat exchanger temperature, and the ambient temperature to determine the recommended speed, the speed of the blower can be accurately matched with the actual operating requirements of the current air conditioning equipment, thereby ensuring that the air conditioning equipment can operate at the most appropriate blower speed under various different conditions, improving the overall operating efficiency of the air conditioning equipment, making the refrigeration or heating effect reach the best state, and at the same time reducing energy waste.

[0041] Specifically, the load condition includes the load current. Obtaining a recommended speed according to the heat exchanger temperature, the ambient temperature, and the previously obtained blower load condition includes: determining the winding temperature according to the load current and the motor winding resistance of the blower obtained previously; obtaining the actual ambient temperature according to the heat exchange temperature and the ambient temperature; and obtaining the recommended speed according to the motor winding temperature and the actual ambient temperature.

[0042] It should be added that in the blower motor, when the load current flows through the motor winding, since the motor winding itself has resistance, heat will be generated to increase the winding temperature. Therefore, the winding temperature can be determined by equating the heat generated by the motor winding to the heat absorbed by the motor winding plus the heat dissipated to the surrounding environment.

[0043] In addition, the heat exchanger temperature reflects the state of the heat exchanger after absorbing or releasing heat. Since the heat exchanger is arranged on the air flow channel of the blower so that the air supply volume first passes through the heat exchanger and then through the motor, correspondingly, the heat exchanger temperature will affect the heat of the environment around the blower and reduce the ambient temperature. Therefore, the actual ambient temperature needs to be deduced by using the heat exchange principle based on the heat exchanger temperature and the currently measured ambient temperature.

[0044] In addition, the rotational speed of the fan is closely related to the performance of the motor, and the motor performance is affected by the temperature of the motor winding and the ambient temperature. An increase in the winding temperature will cause an increase in the resistance of the motor winding. At the same time, the ambient temperature will also affect the performance of the motor. Therefore, based on the motor winding temperature and the actual ambient temperature, the recommended rotational speed is determined to adjust the operating state of the fan in real time, enabling the input energy of the motor to be more effectively converted into the mechanical energy of the fan, improving the output air volume and pressure of the fan, and thus enhancing the refrigeration or heating effect of the air conditioning system.

[0045] In addition, according to the recommended rotational speed, the maximum operating rotational speed of the fan is adjusted, including: determining whether the recommended rotational speed exceeds the target rotational speed. If it exceeds, the corresponding maximum operating rotational speed is adjusted according to the target rotational speed; where the target rotational speed is determined based on the limit current, and the limit current is determined based on the rated current of the fan motor; otherwise, the corresponding maximum operating rotational speed is adjusted according to the recommended rotational speed.

[0046] It should be noted that the rated current is determined based on the rated power, rated voltage, and rated efficiency of the fan motor. The limit current can generally be several times the rated current, which can be specifically set according to actual design requirements and will not be further limited here. In addition, by controlling the fan rotational speed not to exceed the target rotational speed, it is ensured that the fan operates within a safe rotational speed range, avoiding problems such as blade deformation and fracture caused by too high a rotational speed of the fan, and at the same time avoiding increasing the load on the motor, avoiding overheating and even burning out of the motor, prolonging the service life of the fan, reducing the cost of equipment maintenance and replacement, and ensuring the stable operation of the air conditioning system.

[0047] Furthermore, before determining whether the recommended rotational speed exceeds the target rotational speed, it includes: determining the fan load type, and according to the fan load type, obtaining the corresponding load parameters; according to the load parameters, looking up the previously obtained motor characteristic curve, determining the corresponding rotational speed range, and combining with the limit current, determining the target rotational speed.

[0048] Even further, according to the fan load type, obtaining the corresponding load parameters includes: if the fan load type is a constant torque load, the resistance torque of the load is directly measured by a torque sensor or calculated according to parameters such as the mechanical structure and friction coefficient of the load to obtain the load parameters; if the fan load type is a square torque load, according to factors such as the impeller diameter, blade shape, and air density of the fan, the load coefficient is calculated through fluid mechanics formulas or experimentally determined to obtain the load parameters; if the fan load type is a constant power load, according to the corresponding rated power requirements, the torque requirements corresponding to different rotational speeds are converted to obtain the load parameters.

[0049] In an alternative embodiment, reference Figure 2, after controlling the blower to operate at the highest operating speed or the adjusted highest operating speed, it includes: monitoring the air conditioner operating mode, and based on the air conditioner operating mode being the strong operation mode, adjusting the speed of the outdoor blower according to the target speed, and recording the operating time; wherein, the strong operation mode is used to represent the air conditioner working mode of operating with the maximum cooling or heating capacity, the target speed is determined based on the limit current, and the limit current is determined based on the rated current of the blower motor; based on the operating time reaching the preset time threshold, according to the strong operation mode, combined with the preset cooling control strategy, controlling the heat exchanger arranged on the air flow channel of the outdoor blower to cool down, so as to cool down the motor and the electronic control system of the outdoor blower.

[0050] It should be noted that after entering the strong operation mode, the speed of the outdoor blower is adjusted to the target speed determined based on the limit current, and the operating time is recorded. Subsequently, according to the preset cooling control strategy, the heat exchanger is controlled to cool down to cool down the motor and the electronic control system of the outdoor blower, so as to fully consider the high-load operation situation of the equipment in the strong operation mode, avoid damage to the motor due to overload through reasonable highest speed setting, and at the same time, combined with the preset cooling control strategy, accurately control the heat exchanger on the air flow channel of the outdoor blower to make it cool down to absorb the heat generated by the motor and the electronic control system, effectively prevent equipment failures caused by overheating, ensure the stable operation of the equipment during strong operation, reduce the number of shutdown and maintenance times caused by equipment failures, extend the service life of the equipment, and provide continuous and reliable air conditioner services for users. In addition, the target speed can be determined based on the above method for determining the target speed, and no repeated elaboration is made here.

[0051] Furthermore, before adjusting the speed of the outdoor blower according to the target speed and recording the operating time based on the air conditioner operating mode being the strong operation mode, it includes: determining whether the air conditioner usage requirement can be completed within the target time according to the previously obtained air conditioner usage requirement and the overall machine operating conditions, and based on the inability to complete the air conditioner usage requirement within the target time, determining that the air conditioner operating mode enters the strong operation mode.

[0052] It should be noted that by pre-obtaining the air conditioner usage requirement and the overall machine operating conditions, accurately judging whether the air conditioner usage requirement can be completed within the target time, and based on this, determining whether to enter the strong operation mode, so as to avoid unnecessary strong operation, ensure that the air conditioner enters this mode only when it truly needs the maximum cooling or heating capacity, maximize the air conditioner operation efficiency, quickly meet the user's comfort requirements, reduce energy consumption, and lower the user's usage cost.

[0053] Further, according to the previously obtained air conditioner usage requirements and the operating conditions of the whole machine, it is determined whether the air conditioner usage requirements can be met within the target time, including: according to the previously obtained operating conditions of the whole machine, determining the time required to reach the target temperature to obtain the estimated time; determining whether the estimated time exceeds the target time, if it exceeds, it is determined that the air conditioner usage requirements cannot be met within the target time; otherwise, it is determined that the air conditioner usage requirements can be met within the target time.

[0054] It should be added that the air conditioner usage requirements are used to represent the user's requirements for reaching the target temperature within the target time, which can be determined based on the user's usage requirements. By judging whether the air conditioner usage requirements can be met within the target time through the host computer, it is determined whether to enter the strong operation mode, so that the energy consumption of the air conditioner is more matched with the actual requirements, providing a personalized and precise comfortable environment solution for users and meeting the diverse life scenario requirements of users. In addition, the operating conditions of the whole machine are used to represent the performance of the air conditioner itself and the current working state, generally covering the air conditioner's cooling / heating capacity, the air volume and wind speed range of the fan, the operating frequency range of the compressor, the heat exchange efficiency of the heat exchanger, and the energy efficiency ratio of the air conditioner, etc. The air conditioner's cooling / heating capacity can be expressed by the rated cooling capacity / heating capacity, with the unit of watt, which is used to represent the amount of heat that the air conditioner can remove or add from the indoor environment per unit time. The heat exchange efficiency of the heat exchanger can be determined according to factors such as the type, area, and material of the heat exchanger. The energy efficiency ratio of the air conditioner is used to represent the cooling capacity or heating capacity that can be generated per unit of electrical energy consumed under different operating conditions.

[0055] In addition, the strong operation mode includes a strong heating mode and a strong cooling mode. The strong heating mode is mainly used in the heating mode for scenarios where the room temperature needs to be increased within the target time, and the strong cooling mode is mainly used in the cooling mode for scenarios where the room temperature needs to be decreased within the target time.

[0056] In another alternative embodiment, after controlling the fan to operate at the highest operating speed or the adjusted highest operating speed, it further includes: monitoring the air conditioner operation mode, and based on the air conditioner operation mode being the strong operation mode, monitoring the motor winding temperature of the outdoor fan; wherein, the strong operation mode is used to represent the air conditioner working mode that operates with the maximum cooling or heating capacity; based on the motor winding temperature exceeding the first preset temperature threshold, according to the strong operation mode, combined with the preset cooling control strategy, controlling the heat exchanger arranged on the air flow channel of the outdoor fan to cool, so as to cool the motor and the electric control system of the outdoor fan.

[0057] It should be noted that after entering the strong operation mode, by continuously monitoring the temperature of the motor winding, when the temperature exceeds the first preset temperature threshold, cooling measures are taken in a timely manner, combined with the preset cooling control strategy, to precisely control the heat exchanger on the air flow channel of the outdoor fan, so that it cools down to absorb the heat generated by the motor and the electric control system, effectively preventing equipment failures caused by overheating, ensuring the stable operation of the equipment during strong operation, reducing the number of shutdown and maintenance times due to equipment failures, extending the service life of the equipment, and providing continuous and reliable air conditioning services for users.

[0058] In another alternative embodiment, after controlling the fan to operate at the highest operating speed or the adjusted highest operating speed, it further includes: monitoring the air conditioning operation mode, and based on the air conditioning operation mode being the strong operation mode, monitoring the temperature of the electric control system of the outdoor unit; wherein, the strong operation mode is used to represent the air conditioning working mode that operates with the maximum cooling or heating capacity; based on the temperature of the electric control system exceeding the second preset temperature threshold, according to the strong operation mode, combined with the preset cooling control strategy, control the heat exchanger arranged on the air flow channel of the outdoor fan to cool down, so as to cool down the motor and the electric control system of the outdoor fan.

[0059] It should be noted that after entering the strong operation mode, by continuously monitoring the temperature of the electric control system, when the temperature exceeds the second preset temperature threshold, cooling measures are taken in a timely manner, combined with the preset cooling control strategy, to precisely control the heat exchanger on the air flow channel of the outdoor fan, so that it cools down to absorb the heat generated by the motor and the electric control system, effectively preventing equipment failures caused by overheating, ensuring the stable operation of the equipment during strong operation, reducing the number of shutdown and maintenance times due to equipment failures, extending the service life of the equipment, and providing continuous and reliable air conditioning services for users.

[0060] In an alternative embodiment, according to the strong operation mode, combined with the preset cooling control strategy, controlling the heat exchanger arranged on the air flow channel of the outdoor fan to cool down, so as to cool down the motor and the electric control system of the outdoor fan, includes: based on the strong operation mode being the strong cooling mode, determining that the preset cooling control strategy is to control the indoor fan to stop operating, control the outdoor fan to decelerate and operate at the previously determined optimal heat dissipation speed, and control the state switching of the outdoor unit four-way valve; based on the strong operation mode being the strong heating mode, determining that the preset cooling control strategy is to control the outdoor fan to decelerate and operate at the previously determined optimal heat dissipation speed; execute corresponding control according to the determined preset cooling control strategy, so as to control the heat exchanger arranged on the air flow channel of the outdoor fan to cool down, and cool down the motor and the electric control system of the outdoor fan.

[0061] It should be noted that when the strong operation mode is the strong cooling mode, the indoor fan is controlled to stop running to reduce unnecessary energy consumption. The outdoor fan is controlled to operate at a reduced speed according to the optimal heat dissipation speed to avoid excessive energy consumption caused by the high-speed operation of the fan. At the same time, sufficient air flow can pass through the heat exchanger to achieve effective refrigeration and cooling, concentrating the refrigeration resources on the cooling requirements of key outdoor equipment, improving the energy utilization efficiency of the entire air conditioning system in the strong cooling mode, and controlling the switching of the state of the outdoor unit four-way valve to change the flow direction of the refrigerant, so that the heat exchanger of the outdoor unit acts as an evaporator. When the refrigerant flows through the heat exchanger of the outdoor unit, it will absorb heat from the surrounding environment (including the motor and the electric control system), thereby reducing the temperature of the motor and the electric control system.

[0062] In addition, in the strong heating mode, since heating needs to be maintained, the four-way valve of the outdoor unit and the indoor unit continue to maintain their original operating states to ensure that the indoor heat output does not fluctuate violently, accurately maintaining the heating effect indoors, so that users can continuously enjoy a comfortable and stable warm environment. And, since the outdoor heat exchanger is originally in the state of absorbing heat and evaporating during heating, by controlling the outdoor fan to operate at a reduced speed, on the basis of cooling the corresponding motor and electric control, the stable operation of the outdoor motor and electric control system is ensured.

[0063] It should be added that the electric control system includes an outdoor control board, sensors, relays, contactors, and power modules, etc. Electric control refers to the electrical control system in the air conditioning system, which is responsible for controlling and managing each component of the air conditioner to ensure that the air conditioning system can operate stably and efficiently according to the preset mode, parameters, and user requirements.

[0065] It should be noted that by real-time monitoring the temperature of the outdoor fan motor and the electronic control system temperature and comparing them with the corresponding preset temperatures respectively to determine whether the motor temperature and the electronic control system temperature are reduced to the corresponding preset temperatures, thereby dynamically adjusting the cooling strategy according to the real-time feedback of the motor temperature and the electronic control system temperature to ensure that the motor and the electronic control system are cooled to the corresponding preset temperatures and maintain the stable output of the overall performance of the air conditioning system; in addition, after the motor temperature and the electronic control system temperature are reduced to the corresponding preset temperatures, further determine whether to exit the forced operation mode, so as to accurately adjust the operation mode according to the actual temperature state on the premise of ensuring the safe operation of the equipment, avoid excessive energy consumption when the forced operation mode is not required, and achieve the perfect coordination of intelligent energy saving and operation mode.

[0066] Further, determining whether the air conditioner usage requirement is completed includes: judging whether the current air conditioner temperature reaches the target temperature required by the air conditioner usage requirement, and if so, determining that the air conditioner usage requirement is completed.

[0067] Further, after determining to exit the forced operation mode, it includes: judging whether to shut down, and if so, ending the process; otherwise, repeating the above method in a loop.

[0068] In summary, in the embodiment of the present invention, by obtaining the temperature of the heat exchanger and the ambient temperature of the blower, comparing the two on this basis, and combining the air conditioner operation mode to determine whether to adjust the maximum operating speed of the blower, it is helpful to accurately judge the maximum speed of the blower by considering various actual situations, so that the operating state of the blower can better adapt to the overall operation requirements of the current air conditioner system.
