[0042] With reference to the drawings of the embodiments herein, the technical solutions in the embodiments will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments herein, all the other embodiments obtained by a person of ordinary skill in the art without creative effort are within the protection scope of the present application.

[0043] Reference herein to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment nor are they necessarily mutually exclusive or alternative embodiments. It is explicitly contemplated that embodiments described herein can be combined with other embodiments.

[0044] An air conditioning system generally comprises an outdoor unit system and an indoor unit system, wherein the outdoor unit system is responsible for compression condensation, and the indoor unit system is responsible for heat exchange. The air conditioning system needs to simultaneously open the outdoor unit system and the indoor unit system to normally operate. In the process of operation of the air conditioning system, a certain amount of lubricating oil needs to be ensured in the compressor in the outdoor unit system of the air conditioning system, so as to avoid the wear of the compressor, thereby ensuring the normal operation of the air conditioning system.

[0045] In order to solve the problem that a certain amount of lubricating oil cannot be ensured in the compressor in the related art, the present application provides a control method of an air conditioning outdoor unit system.

In the present application, the outdoor fan gear is controlled by the outdoor environment temperature when the air conditioning outdoor unit system is in the start state. When the outdoor environment temperature is high, the fan gear is reduced, and when the outdoor environment temperature is low, the fan gear is not reduced. A certain amount of lubricating oil can be ensured in the compressor, thereby improving the reliability of the operation of the air conditioning system, and the present application can solve the problem of insufficient oil in the compressor.

[0046] Next, please refer to FIG. 1, which is an architecture schematic diagram of an air conditioning system provided by an embodiment of the present application. The air conditioning outdoor unit system provided by the present application is an important component of the air conditioning system. The air conditioning system generally comprises an air conditioning indoor unit system, an air conditioning outdoor unit system, a refrigerant pipeline system, an electrical control system, an air handling system, and a drainage system, etc. main components, wherein:

[0047] Air conditioner indoor unit system: The air conditioning machine usually installed in the room, responsible for circulating and adjusting the temperature, humidity and cleanliness of indoor air. The indoor unit usually includes fan, evaporator and filter and other components.

[0048] Air conditioner outdoor unit system: The air conditioning machine installed in the outdoor, responsible for heat dissipation and refrigeration, expelling the heat of the indoor, while carrying out the refrigeration cycle.

[0051] Air handling system: Equipment for purifying, circulating, heating or humidifying indoor air, such as air filter, humidifier, etc.

[0052] Drainage system: For discharging water vapor or condensate produced by indoor unit to ensure indoor dryness and cleanliness.

[0053] It should be noted that the above introduction is the main components of the air conditioning system, different types of air conditioning systems may have some changes or additional parts, such as the case of multi-split system, there will be multiple indoor units connected to one outdoor unit.

[0054] In an embodiment, the air conditioner outdoor unit system involved in this application usually includes compressor, condenser, outdoor fan, control components, connecting pipe and shell and bracket and other main components, among which:

[0055] Compressor: One of the most important components in the air conditioning system, responsible for compressing refrigerant gas, increasing the temperature and pressure of the gas, making it into high temperature and high pressure gas.

[0056] Condenser: The condenser is where the high temperature and high pressure gas discharged by the compressor is cooled and condensed into high pressure liquid, releasing heat to the outside air.

[0057] Outdoor fan: The air conditioner outdoor unit usually installs a fan to dissipate heat through the condenser, helping to cool down and speed up the cooling effect.

[0058] Control components: Including sensors, control panels and other components, used to monitor outdoor environmental temperature, pressure and other parameters, and control the operation status of compressor, fan, etc.

[0059] Connecting pipe: The pipe connecting indoor unit and outdoor unit, used for circulating refrigerant flow.

[0060] Casing and bracket: including the external protective shell and bracket of the outdoor unit, used for fixing and protecting the outdoor unit of the air conditioner.

[0061] The above-mentioned parts collectively constitute an air conditioner outdoor unit system, which plays an important role in discharging indoor heat and performing refrigeration cycle. In the air conditioner outdoor unit system, each component cooperates with each other to complete the refrigeration cycle and heat dissipation work together, ensuring the normal operation of the air conditioning system.

[0062] Next, in combination with FIGS. 1-2, a control method of an air conditioner outdoor unit system is introduced, the execution subject of the control method of the air conditioner outdoor unit system can be a control device of the air conditioner outdoor unit system provided by the embodiments of the present application, or an electronic device integrated with the control device of the air conditioner outdoor unit system, wherein the control device of the air conditioner outdoor unit system can be realized in the form of hardware or software.

[0063] Please refer to FIG. 3, which is a first flowchart of the control method of the air conditioner outdoor unit system provided by the embodiments of the present application. The specific process of the control method of the air conditioner outdoor unit system provided by the embodiments of the present application can be as follows:

[0064] S110, detecting the power-on signal of the air conditioner outdoor unit system and the outdoor ambient temperature.

[0065] Among them, in the electronic device, the signal usually used to start the device or execute a specific function is called a power-on signal. The power-on signal can be a voltage signal, a pulse signal, a digital signal or other forms of signals, and its purpose is to tell the device to start running or execute certain tasks.

[0066] For the air conditioning system, the power-on signal is usually a voltage signal. For example, when the user presses the power-on button on the air conditioner remote controller, the remote controller will send a specific electrical signal to the air conditioner indoor unit system or the air conditioner outdoor unit system, informing the air conditioning system to start working. The air conditioning system converts the power-on signal into corresponding operation instructions, such as starting the compressor, increasing the wind speed, etc., so that the air conditioning system starts running and provides cooling or heating effect.

[0067] It can be understood that the user can start the air conditioner outdoor unit system by sending a power-on signal to the air conditioner system, so that the air conditioner outdoor unit system is in a working state.

[0068] In the embodiments of the present application, the air conditioner outdoor unit system can determine whether the air conditioner outdoor unit system is in a working state by detecting the voltage signal corresponding to the power-on signal.

[0069] In an embodiment, the working state of the air conditioner outdoor unit system includes an on state, a standby state, an off state, etc., which can be determined by detecting the voltage, current or power of each component of the air conditioner outdoor unit system, or by detecting whether there is a working task in the controller of the air conditioner outdoor unit system. The working task can be refrigeration, heating, defrosting, etc. For example, when the controller is powered on and has no working task, the air conditioner outdoor unit system is in a standby state.

[0070] In addition, in the embodiments of the present application, a temperature sensor for detecting the outdoor environment temperature can be deployed in advance on the air conditioner outdoor unit system, so that the air conditioner outdoor unit system can obtain the outdoor environment temperature through the pre-set temperature sensor.

[0071] S120, if the start-up signal is detected and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan is controlled to reduce from the target gear corresponding to the start-up signal to a preset first gear.

[0072] The target gear is the gear of the outdoor fan corresponding to the start-up of the air conditioner outdoor unit system. The gear can be the gear through the default running logic of the air conditioner outdoor unit system after starting, or a gear set by the user. Here, there is no limitation, which does not affect the overall logic of the control method of the air conditioner outdoor unit system provided by the present application.

[0073] The preset first environment temperature threshold is a temperature threshold set by a person skilled in the art according to the actual situation. For example, in the embodiments of the present application, the value range of the preset first environment temperature threshold can be 5-15 degrees Celsius. The value of the preset first environment temperature threshold can be any value in the value range, for example, the preset first environment temperature threshold is set to 15 degrees Celsius.

[0074] The preset first gear is a gear corresponding to a lower motor speed of the outdoor fan. The preset first gear can be selected by a person skilled in the art according to the gear setting of the outdoor fan of the air conditioner outdoor unit system. For example, if the gears of the outdoor fan are high, medium and low gears, the preset first gear can be set to the low gear.

[0075] It can be understood that when the start-up signal of the air conditioner outdoor unit system is detected, it means that the air conditioner outdoor unit system is in a working state. When the air conditioner outdoor unit system is detected to be in a working state and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan of the air conditioner outdoor unit system is controlled to reduce from the target gear corresponding to the start-up signal to the preset first gear.

[0076] It should be noted that when the outdoor environment temperature is greater than the first preset environment temperature threshold, the outdoor environment temperature is considered to be in a high temperature state, the refrigerant migrates from high temperature to low temperature, and the refrigerant will carry lubricating oil out of the compressor, so that the oil amount in the compressor is low during the starting stage of the air conditioner outdoor unit system.

[0077] In this application, when the outdoor environment temperature is in a high temperature state, the gear of the outdoor fan of the air conditioner outdoor unit system is lowered to reduce the heat exchange performance of the fan, thereby increasing the refrigerant circulation rate and further increasing the refrigerant circulation flow, so as to accelerate the migrated lubricating oil to return to the compressor, thereby ensuring that a certain amount of lubricating oil exists in the compressor.

[0078] In an embodiment, the step S120 "if the starting signal is detected, and the outdoor environment temperature is greater than the first preset environment temperature threshold, the outdoor fan is controlled to be lowered from the target gear corresponding to the starting signal to the first preset gear" can include:

[0079] If the starting signal is detected, the starting signal indicates that the air conditioner outdoor unit system is powered on, and the outdoor environment temperature is greater than the first preset environment temperature threshold, the outdoor fan is controlled to be lowered from the target gear corresponding to the starting signal to the first preset gear.

[0080] The starting signal indicating that the air conditioner outdoor unit system is powered on means that the starting of the air conditioner outdoor unit system at this time is the starting after the power supply is disconnected and then connected.

[0081] In the embodiment of the application, if the detected starting signal of the air conditioner outdoor unit system indicates that the air conditioner outdoor unit system is powered on, and the outdoor environment temperature is greater than the first preset environment temperature threshold, the outdoor fan is controlled to be lowered from the target gear to the first preset gear.

[0082] In an embodiment, the step S120 "if the starting signal is detected, and the outdoor environment temperature is greater than the first preset environment temperature threshold, the outdoor fan is controlled to be lowered from the target gear corresponding to the starting signal to the first preset gear" can include:

[0083] If the starting signal is detected, the standby time of the air conditioner outdoor unit system before the starting signal is detected is greater than or equal to the first preset standby time, and the outdoor environment temperature is greater than the first preset environment temperature threshold, the outdoor fan is controlled to be lowered from the target gear corresponding to the starting signal to the first preset gear.

[0084] The preset first standby time length is set by a person skilled in the art according to an actual scene. Generally, when the standby time length of the air conditioner outdoor system in a high-temperature state exceeds a certain standby time length, the oil amount in the compressor is prone to be insufficient, and then the specific value of the standby time length can be used as a parameter corresponding to the preset first standby time length in the embodiment of the application. The specific value of the standby time length can be an empirical value obtained through multiple tests.

[0085] In the embodiment of the application, if the start-up signal of the air conditioner outdoor system is detected, and the standby time length of the air conditioner outdoor system before the start-up is greater than or equal to the preset first standby time length, and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan is reduced from the target gear to the preset first gear after the air conditioner outdoor system starts up in response to the start-up signal.

[0086] In an embodiment, after the step S120 "if the start-up signal is detected, and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan is controlled to be reduced from the target gear corresponding to the start-up signal to the preset first gear", the following steps can also be included:

[0087] detecting a first running time length of the outdoor fan running at the preset first gear;

[0088] If the first running time length is greater than or equal to a preset first running time length, the outdoor fan is controlled to execute a default running logic of the air conditioner outdoor system after start-up, which is pre-configured.

[0089] The first running time length can be set by a person skilled in the art according to an actual scene, which is not specifically limited here.

[0090] In the embodiment of the application, the first running time length of the outdoor fan of the air conditioner outdoor system running at the preset first gear is detected, and if the first running time length is greater than or equal to the preset first running time length, the outdoor fan is controlled to execute a default running logic of the air conditioner outdoor system after start-up, which is pre-configured.

[0091] It should be noted that the default running logic in the embodiment of the application refers to the logic of the air conditioner outdoor system after start-up, which is not specifically limited here.

[0092] For example, the default operation logic of the air conditioner outdoor unit system after starting can be the factory default operation logic, for example, the default operation logic can be an automatic operation mode, that is, the air conditioner outdoor unit system can automatically select the cooling or heating function by detecting the indoor and outdoor temperature. The default operation mode can also be the operation logic set by the user last time, for example, the air conditioner outdoor unit system can work according to the temperature, wind speed and wind direction set by the user last time. In an embodiment, after step S120, the following steps can also be included:

[0093] detecting the condensing temperature in the air conditioner outdoor unit system;

[0094] If the condensing temperature is greater than or equal to the preset condensing temperature high temperature protection threshold, the gear of the outdoor fan is adjusted from the preset first gear to the highest gear corresponding to the outdoor fan, and the outdoor fan is controlled to execute the default operation logic of the air conditioner outdoor unit system after starting.

[0095] It should be noted that the condensing temperature high temperature protection threshold is a key parameter in the air conditioner system, which is used to avoid overheating of the condenser and protect the normal operation of the air conditioner system. When the condensing temperature exceeds the set high temperature protection threshold, the air conditioner outdoor unit system will automatically stop running to avoid overheating.

[0096] In the embodiment of the present application, in order to avoid the air conditioner outdoor unit system from stopping due to the condensing temperature being too high during operation at the preset first gear, the outdoor fan gear is adjusted to the highest gear when the condensing temperature is greater than or equal to the preset condensing temperature high temperature protection threshold, and the outdoor fan is controlled to execute the default operation logic of the air conditioner outdoor unit system after starting.

[0097] S130, if the starting signal is detected and the outdoor environment temperature is less than or equal to the preset first environment temperature threshold, the outdoor fan gear of the air conditioner outdoor unit system is controlled to be greater than or equal to the target gear corresponding to the starting signal.

[0098] It should be noted that when the outdoor environment temperature is less than or equal to the preset first environment temperature threshold, the outdoor environment temperature is considered to be in a low temperature state, and the refrigerant migrates from high temperature to low temperature, at this time, there is more liquid refrigerant, more oil compatible with it, resulting in higher oil discharge, and then causing the oil in the compressor to be emptied during the starting stage, so that the oil in the compressor is insufficient.

[0099] In the embodiment of the present application, when the start signal is detected, it indicates that the air conditioner outdoor system is in a working state. When the air conditioner outdoor system is detected to be in a working state and the outdoor environment temperature is less than or equal to the preset first environment temperature threshold, the gear of the outdoor fan is controlled to be greater than or equal to the target gear.

[0100] In the present application, when the outdoor environment temperature is in a low temperature state, the gear of the outdoor fan system of the air conditioner outdoor system is maintained from being reduced, the heat exchange performance of the fan is improved, thereby reducing the flow of the system refrigerant, and further reducing the oil discharge rate, so as to ensure that a certain amount of lubricating oil exists in the compressor.

[0101] In an embodiment, after the step S130 "if the start signal is detected, and the outdoor environment temperature is less than or equal to the preset first environment temperature threshold, the gear of the outdoor fan of the air conditioner outdoor system is controlled to be greater than or equal to the target gear corresponding to the start signal", it can further include:

[0102] detecting a second running time length during which the gear of the outdoor fan of the air conditioner outdoor system runs at greater than or equal to the target gear corresponding to the start signal;

[0103] if the second running time length is greater than or equal to a preset second running time length, controlling the outdoor fan to execute a default running logic of the air conditioner outdoor system after starting.

[0104] The preset second running time length can be set by a person skilled in the art according to the amount of lubricating oil in the compressor in the actual scene, which is not limited here. For example, the change of the amount of lubricating oil in the compressor when the outdoor fan runs at greater than or equal to the target gear can be recorded, and the preset second running time length can be determined according to the change of the amount of lubricating oil. The amount of lubricating oil in the compressor at the preset second running time length reaches a reliable range, and the oil amount in the reliable range can make the compressor work normally.

[0105] In the embodiment of the present application, if the second running time length during which the gear of the outdoor fan of the air conditioner outdoor system runs at greater than or equal to the target gear corresponding to the start signal is greater than or equal to the preset second running time length, the outdoor fan is controlled to execute the default running logic.

[0106] In the implementation, the present application is not limited by the execution order of the various steps, and certain steps can also be performed in other orders or simultaneously without conflict.

[0107] It can be understood that the user can start the air conditioner outdoor unit system by sending a start signal to the air conditioner system, so that the air conditioner outdoor unit system is in a working state.

[0108] Next, in order to more clearly illustrate the control method of the air conditioner outdoor unit system provided by the present application, please refer to FIG. 4, which is a second flowchart of the control method of the air conditioner outdoor unit system provided by the present application, which specifically includes the following steps:

[0109] S210, detecting a start signal for the outdoor fan system and detecting an outdoor environment temperature.

[0110] It can be understood that the user can start the air conditioner outdoor unit system by sending a start signal to the air conditioner system, so that the air conditioner outdoor unit system is in a working state.

[0111] In the present application, the air conditioner outdoor unit system can determine whether the air conditioner outdoor unit system is in a working state by detecting the voltage signal corresponding to the start signal.

[0112] In addition, in the present application, a temperature sensor for detecting the outdoor environment temperature can be deployed in advance on the air conditioner outdoor unit system, so that the air conditioner outdoor unit system can obtain the outdoor environment temperature through the pre-set temperature sensor.

[0113] S220, if the start signal is detected, the start signal indicates that the air conditioner outdoor unit system is powered on, and the outdoor environment temperature is greater than the preset first environment temperature threshold, then the outdoor fan is controlled to reduce from the target gear corresponding to the start signal to the preset first gear, and turn to S6.

[0114] Wherein, the start signal indicating that the air conditioner outdoor unit system is powered on means that the start of the air conditioner outdoor unit system at this time is through the start after disconnecting the power supply to connecting the power supply.

[0115] In the embodiment of the present application, if the detected power-on signal of the air conditioner outdoor system indicates that the air conditioner outdoor system is powered on, and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan is controlled to be reduced from the target gear to the preset first gear.

[0116] S230, if the power-on signal is detected, the standby time of the air conditioner outdoor system before the power-on signal is detected is greater than or equal to the preset first standby time, and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan is controlled to be reduced from the target gear corresponding to the power-on signal to the preset first gear, and goes to S6.

[0117] The preset first standby time is set by those skilled in the art according to the actual scene. Generally, when the standby time of the air conditioner outdoor system in the high temperature state exceeds a certain standby time, it is easy to cause insufficient oil in the compressor, so the specific value of this standby time can be used as the parameter corresponding to the preset first standby time in the embodiment of the present application.

[0118] In the embodiment of the present application, if the power-on signal of the air conditioner outdoor system is detected, the air conditioner outdoor system is powered on in response to the power-on signal, the standby time of the air conditioner outdoor system before the power-on is greater than or equal to the preset first standby time, and the outdoor environment temperature is greater than the preset first environment temperature threshold, the outdoor fan is reduced from the target gear to the preset first gear.

[0119] S240, if the power-on signal is detected, and the outdoor environment temperature is less than or equal to the preset first environment temperature threshold, the outdoor fan gear of the air conditioner outdoor system is controlled to be greater than or equal to the target gear corresponding to the power-on signal, and goes to S8.

[0120] In the embodiment of the present application, when the power-on signal is detected, it indicates that the air conditioner outdoor system is in working state. When the air conditioner outdoor system is detected in working state, and the outdoor environment temperature is less than or equal to the preset first environment temperature threshold, the gear of the outdoor fan is controlled to be greater than or equal to the target gear.

[0123] It should be noted that when the environment temperature is greater than the preset second environment temperature threshold, the compressor does not have an oil return problem, and therefore, in the embodiment of the present application, if the start signal is detected and the outdoor environment temperature is greater than the preset second environment temperature threshold, the outdoor fan is controlled to execute the preconfigured default operation logic of the air conditioner outdoor unit system after starting. The preset second environment temperature threshold is greater than the preset first environment temperature threshold.

[0124] In the embodiment of the present application, the default operation logic refers to the logic of the air conditioner outdoor unit after starting. The default operation logic is not limited here.

For example, the default operation logic can be an automatic operation mode, that is, the air conditioner outdoor unit system can automatically detect indoor and outdoor temperatures to perform corresponding work, such as automatically selecting a cooling or heating function. The default operation mode can also be the operation logic set by the user last time, for example, the air conditioner outdoor unit system can perform work according to the temperature, air speed, and air direction set by the user last time.

[0129] In the embodiment of the present application, in order to avoid that the condensing temperature is too high to trigger the shutdown of the air conditioner outdoor unit system during the process of running through the preset first gear, the present application sets that if the condensing temperature is greater than or equal to the preset condensing temperature high temperature protection threshold, the gear of the outdoor fan is adjusted to the highest gear, which is the gear corresponding to the highest motor speed of the outdoor fan, and then the outdoor fan is controlled to execute the default running logic of the air conditioner outdoor unit system after starting.

[0130] S280, detecting a second running time length of the outdoor fan gear of the air conditioner outdoor unit system running at a gear greater than or equal to the target gear corresponding to the starting signal; if the second running time length is greater than or equal to a preset second running time length, the outdoor fan is controlled to execute the default running logic of the air conditioner outdoor unit system after starting.

[0131] In the embodiment of the present application, if it is detected that the second running time length of the outdoor fan gear of the air conditioner outdoor unit system running at a gear greater than or equal to the target gear corresponding to the starting signal is greater than or equal to the preset second running time length, the outdoor fan is controlled to execute the default running logic.
