[0052] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the application scenario of the disclosed solution is first described below.

[0053] Normally, the air-conditioning compressor lubricant can lubricate the friction surface of the internal moving parts, take away the friction heat to cool the friction surface, reduce the mechanical wear of the parts, ensure the reliability of the compressor, and take away the friction debris generated during the process. However, when the air-conditioning compressor is left in a low-temperature environment for a long time, the compressor's lubricant will freeze and become sticky, causing the compressor's starting resistance to increase, resulting in the compressor's easy start failure in a low-temperature environment.

[0054] At present, in the related technology, when the compressor is in standby state, the external electric heating belt or the compressor stator winding coil is energized to control the heating at a fixed period to alleviate the problem of compressor lubricating oil viscosity and solve the problem of low-temperature startup reliability. However, the equipment characteristics of the electric heating belt or stator winding will cause the problem of high power consumption. In addition, the external heating device will increase the hardware cost, and when the air conditioner is in standby state, the indoor unit needs to attract the power relay of the outdoor unit at intervals to power the outdoor unit, which will make the user feel that the air conditioner is idling in standby state, reducing the user experience.

[0055] In order to solve the above problems, exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0057] Figure 1 is a flow chart of a compressor startup control method according to an exemplary embodiment. Figure 1 As shown, the following steps are included.

[0058] In step S11 , in response to receiving a start-up signal of the air conditioner, the outdoor ambient temperature and the idle time of the air conditioner compressor are acquired.

[0059] like Figure 2 As shown, Figure 2 This is a structural diagram of the connection between the air conditioner indoor unit and the air conditioner outdoor unit. Usually, after the air conditioner indoor unit is powered on, the power supply unit of the air conditioner indoor unit will supply power to the air conditioner outdoor unit, and the air conditioner indoor unit can establish a communication connection with the air conditioner outdoor unit, and the frequency conversion drive unit of the air conditioner outdoor unit can drive the air conditioner compressor to rotate through a PWM (Pulse Width Modulation) signal.

[0060] Generally, in a low temperature environment, the lubricating oil of the compressor will freeze and become viscous, which will affect the startup of the air conditioner compressor. Therefore, after receiving the air conditioner startup signal, the outdoor environment temperature and the static time can be obtained in this embodiment, so as to characterize the state of the lubricating oil of the air conditioner compressor.

[0061] Specifically, when the air conditioner outdoor unit receives the air conditioner start-up signal, the air conditioner outdoor unit can obtain the idle time counted by the indoor unit control unit of the air conditioner indoor unit according to the communication connection established between the air conditioner outdoor unit and the air conditioner indoor unit, wherein the idle time is the time from the last shutdown moment of the air conditioner compressor to the current moment. At the same time, the air conditioner outdoor unit can collect the current outdoor ambient temperature. For example, the outdoor ambient temperature can be collected by a temperature sensor.

[0062] In addition, the air conditioning compressor may be stopped because the air conditioning is turned off or the indoor temperature reaches the target temperature, and the stop time may be recorded when the air conditioning is stopped.

[0063] In step S12, the lubricating oil viscosity parameter corresponding to the air-conditioning compressor is determined according to the outdoor ambient temperature and the static time.

[0064] Specifically, the applicant has found through research that the viscosity of the lubricating oil corresponding to the air-conditioning compressor is related to the outdoor ambient temperature and the static time. Due to the characteristics of the lubricating oil, the viscosity of the lubricating oil is usually negatively correlated with the outdoor temperature environment and positively correlated with the static time. Therefore, the viscosity parameter of the lubricating oil can be determined based on the influence of the outdoor ambient temperature and the static time on the viscosity of the lubricating oil.

[0065] In step S13 , the target startup parameter of the air-conditioning compressor is determined according to the viscosity parameter of the lubricating oil and the preset startup parameter of the air-conditioning compressor.

[0066] Specifically, the larger the lubricating oil viscosity parameter is, the thicker the lubricating oil is, and the lubricating oil viscosity parameter has an impact on the start-up of the air-conditioning compressor. The greater the viscosity of the lubricating oil is, the more difficult it is to start the air-conditioning compressor. In this embodiment, the start-up parameters of the air-conditioning compressor can be adjusted based on the lubricating oil viscosity parameter so that the determined target start-up parameters match the current state of the air-conditioning compressor.

[0067] In step S14 , the air conditioner compressor is controlled to start based on the target start parameter.

[0068] In this embodiment, the lubricating oil of the air-conditioning compressor can be preheated before starting based on the target starting parameters, so that the air-conditioning compressor can reach a better starting state and control the starting of the air-conditioning compressor, while also improving the reliability of the compressor starting.

[0069] In the above technical solution, when the air conditioner is turned on, the viscosity parameter of the lubricating oil corresponding to the air conditioner compressor is determined according to the outdoor ambient temperature and the standing time of the air conditioner compressor, so that the target starting parameter of the air conditioner compressor can be determined according to the viscosity parameter of the lubricating oil and the preset starting parameter of the air conditioner compressor. The start of the air conditioner compressor is controlled based on the target starting parameter. Since the viscosity of the lubricating oil will affect the starting process of the compressor, and the viscosity of the compressor lubricating oil is related to the outdoor ambient temperature and the standing time. In this way, the target starting parameter of the air conditioner compressor determined by the viscosity parameter of the lubricating oil makes the determined target starting parameter match the current state of the air conditioner compressor, alleviating the difficulty of starting the compressor caused by the freezing and viscosity of the lubricating oil of the compressor in a low temperature environment, and ensuring the safe starting and operation of the air conditioner compressor. In addition, there is no need to set up additional equipment for heating the compressor, which can reduce the power consumption of the air conditioner.

[0070] In a possible embodiment, an exemplary implementation method of determining the lubricating oil viscosity parameter corresponding to the air-conditioning compressor according to the outdoor ambient temperature and the static time may include:

[0071] The standard temperature and standard time for starting the air conditioner compressor, as well as the limit temperature and limit time are obtained, wherein the standard temperature is greater than the limit temperature, and the standard time is less than the limit time.

[0072] Specifically, the standard temperature, standard time, limit temperature and limit time for starting the air-conditioning compressor are determined based on the type of lubricating oil selected for the air-conditioning compressor and the performance parameters of the air-conditioning. They can be pre-set in the outdoor unit control unit of the air-conditioning outdoor unit so that they can be obtained and used when determining the viscosity parameters of the lubricating oil.

[0073] For example, the standard temperature is used to indicate the highest temperature that affects the viscosity of the lubricating oil of the air-conditioning compressor, and the standard duration is used to indicate the minimum standstill duration that affects the viscosity of the lubricating oil of the air-conditioning compressor. The limit temperature is used to indicate the lowest temperature that can be adjusted by the air-conditioning compressor and affects the viscosity of the lubricating oil of the air-conditioning compressor, and the limit duration is used to indicate the maximum standstill duration that can be adjusted by the air-conditioning compressor and affects the viscosity of the lubricating oil of the air-conditioning compressor.

[0074] Among them, setting the standard temperature, standard duration, limit temperature and limit duration can also ensure the adjustable range of parameters when determining the target startup parameters based on the viscosity parameters of the lubricating oil in the future, avoiding the risk caused by adjustments beyond the reliability range of the air conditioner operation. As an example, according to the actual application scenario, the standard temperature can be set to 0°C, the standard duration can be set to 1h, the limit temperature can be set to -30°C, and the limit duration can be set to 48h.

[0075] In addition, in this embodiment, the lubricating oil in the air-conditioning compressor will usually freeze and become viscous in a low-temperature environment. Accordingly, in this embodiment, the standard temperature needs to be greater than the limit temperature.

[0076] Then, the lubricating oil viscosity parameters corresponding to the air-conditioning compressor are determined based on the outdoor ambient temperature, static time, standard temperature, standard time, as well as extreme temperature and extreme time.

[0077] Furthermore, when the outdoor ambient temperature is lower than the standard temperature and the standing time is longer than the standard time, the lubricating oil viscosity parameter corresponding to the air-conditioning compressor is determined according to the outdoor ambient temperature and the standing time.

[0078] Specifically, as mentioned above, the main factors that affect the viscosity of the lubricating oil include the outdoor temperature environment and the standing time. The standard temperature is used to indicate the highest temperature that affects the viscosity of the lubricating oil of the air-conditioning compressor, and the standard time is used to indicate the minimum standing time that affects the viscosity of the lubricating oil of the air-conditioning compressor. If the current outdoor ambient temperature collected is lower than the standard temperature, it can be considered that the air-conditioning compressor is in a low temperature environment at this time, and there may be a risk of the lubricating oil freezing. At the same time, if the acquired standing time is longer than the standard time, it can be considered that the air-conditioning compressor has not been used for a long time in a low temperature environment, and the lubricating oil therein will become more viscous over time. Accordingly, in this scenario, the lubricating oil viscosity parameters corresponding to the air-conditioning compressor can be determined based on the outdoor ambient temperature and the standing time, so as to determine the target startup parameters of the air-conditioning compressor.

[0079] When it is determined that the outdoor ambient temperature and the static time meet the corresponding conditions, the target startup parameters are determined by determining the viscosity parameters of the lubricating oil. This is conducive to the subsequently determined target startup parameters being more suitable for the current state of the air-conditioning compressor, so that the lubricating oil can be better preheated. At the same time, it can also avoid the waste of control startup resources and protect the reliability of the air-conditioning compressor.

[0080] For example, according to the outdoor ambient temperature, the static time, the standard temperature, the standard time, and the limit temperature and the limit time, the implementation method of determining the viscosity parameter of the lubricating oil corresponding to the air-conditioning compressor may include:

[0081] Determine the temperature parameters based on the outdoor ambient temperature, standard temperature and extreme temperature.

[0082] Among them, according to the outdoor environment temperature, the standard temperature and the limit temperature, an exemplary implementation manner of determining the temperature parameter may include:

[0083] The ratio of the difference between the target ambient temperature and the standard temperature to the difference between the limit temperature and the standard temperature is determined as the temperature parameter, wherein if the outdoor ambient temperature is greater than or equal to the limit temperature, the outdoor ambient temperature is used as the target ambient temperature, and if the outdoor ambient temperature is less than the limit temperature, the limit temperature is used as the target ambient temperature.

[0084] Specifically, by performing a linear transformation on the target ambient temperature, the temperature parameter corresponding to the target ambient temperature can be mapped to the interval [0, 1] to facilitate the determination of the lubricating oil viscosity parameter. In addition, by performing interval restrictions on the obtained outdoor ambient temperature, it is possible to prevent the reliable range of the air-conditioning compressor from being exceeded when determining the lubricating oil viscosity parameter. For example, if the outdoor ambient temperature is -31°C, the outdoor ambient temperature at this time is lower than the limit temperature. If the lubricating oil viscosity parameter is determined using -31°C, the subsequent target startup parameter will exceed the reliability range of the air-conditioning compressor startup, which will bring risks to the air-conditioning compressor startup. The limit temperature of -30°C needs to be used as the target ambient temperature.

[0085] Determine the duration parameters based on the static time, standard time and extreme time.

[0086] Among them, the duration parameters are determined according to the static duration, standard duration and limit duration, including:

[0087] The ratio of the difference between the target static time and the standard time to the difference between the limit time and the standard time is determined as the time parameter, wherein, if the static time is greater than the standard time and less than the limit time, the static time is used as the target static time; if the static time is less than or equal to the standard time, the standard time is used as the static time; if the static time is greater than the limit time, the limit time is used as the static time.

[0088] Specifically, by performing a linear transformation on the target standstill time, the time parameter corresponding to the target standstill time can be mapped to the interval [0, 1], so as to facilitate the determination of the lubricating oil viscosity parameter. In addition, by performing interval restriction on the obtained standstill time, it is possible to prevent the reliable range of the air-conditioning compressor startup from being exceeded when determining the lubricating oil viscosity parameter. For example, if the standstill time is 49h, the standstill time at this time is greater than the limit time. If the lubricating oil viscosity parameter is determined using 49h, the subsequent target startup parameter will exceed the reliability range of the air-conditioning compressor startup, which will bring risks to the air-conditioning compressor startup. The limit time of 48h needs to be used as the target standstill time; if the standstill time is 30min, the standstill time at this time is less than the standard time, which will also cause the subsequent target startup parameter to exceed the reliability range of the air-conditioning compressor startup, which will bring risks to the air-conditioning compressor startup. The standard time of 1h needs to be used as the target standstill time.

[0089] The viscosity parameter of the lubricating oil is obtained by performing weighted processing according to the weights corresponding to the temperature parameter and the time parameter.

[0090] The weight of the temperature parameter and the weight of the duration parameter can be set based on the actual application scenario, such as the sum of the weights of the two being equal to 1. For example, the weight of the temperature parameter can be set to 0.5, and the weight of the duration parameter can be set to 0.5.

[0091] Specifically, the impact of temperature parameters and duration parameters on lubricating oil will also be affected by other external factors. For example, lubricating oils from different manufacturers, different types or different batches will be affected by temperature parameters and duration parameters to different degrees. By weighting the temperature parameters and duration parameters, different weights can be set for different lubricating oil types or compressor parameters. For example, the viscosity of the lubricating oil produced by manufacturer A is more obviously affected by temperature parameters, so the weight of the temperature parameter can be set to 0.7 and the weight of the duration parameter can be set to 0.3.

[0092] For example, in this embodiment, the range is normalized in a way of range scaling, and the viscosity parameter of the lubricating oil can be determined by the following formula:

[0093]

[0094] Among them, γ is the viscosity parameter of the lubricating oil, T is the target ambient temperature, T0 is the standard temperature, T lim is the limit temperature, α is the weight of the temperature parameter, s is the target static time, s0 is the standard time, s lim is the limit duration, and β is the weight of the duration parameter.

[0095] In a possible embodiment, the preset starting parameters include a standard open-loop starting time and a standard open-loop starting current for starting the air-conditioning compressor, and a limit open-loop starting time and a limit open-loop starting current for starting the air-conditioning compressor, wherein the standard open-loop starting time is less than the limit open-loop starting time, and the standard open-loop starting current is less than the limit open-loop starting current; an exemplary implementation method of determining the target starting parameters of the air-conditioning compressor according to the lubricating oil viscosity parameter and the preset starting parameters of the air-conditioning compressor may include:

[0096] The target open-loop startup time is determined according to the lubricating oil viscosity parameters and the standard open-loop startup time and the limit open-loop startup time corresponding to the air-conditioning compressor.

[0097] Among them, the open-loop start time can determine the time required to preheat the lubricating oil to start the air-conditioning compressor. Preheating the lubricating oil can reduce the viscosity of the lubricating oil and better start the air-conditioning compressor.

[0098] Specifically, the standard open-loop start-up time can be the shortest open-loop start-up time required for the air-conditioning compressor to start, and the extreme open-loop start-up time can be the longest open-loop start-up time corresponding to the start-up of the air-conditioning compressor; it can be set based on a preliminary test of the compressor and combined with the actual application scenario to protect the reliability of the operation of the air-conditioning compressor. Through the influence of the lubricating oil viscosity parameter on the open-loop start-up time, the target open-loop start-up time suitable for the current outdoor temperature environment and the static time can be determined. For example, the standard open-loop start-up time can be set to 10s, and the extreme open-loop start-up time can be set to 300s.

[0099] For example, the target open-loop startup time may be determined by the following formula according to the lubricating oil viscosity parameter and the standard open-loop startup time and the limit open-loop startup time corresponding to the air-conditioning compressor:

[0100] t=t0+(t lim -t0)*γ, t0≤t≤t lim

[0101] Among them, t is used to represent the target startup time, t0 is used to represent the standard open-loop startup time, and t lim Used to indicate the limit open-loop startup duration.

[0102] In this embodiment, the range of the open-loop startup time is scaled according to the lubricating oil viscosity parameter so that the determined target open-loop startup time can be maintained at [t0, t lim ] range, ensuring the reliability of starting the air-conditioning compressor.

[0103] The target open-loop starting current is determined according to the viscosity parameters of the lubricating oil and the standard open-loop starting current and the limit open-loop starting current corresponding to the air-conditioning compressor.

[0104] Among them, the open-loop starting current can determine the output torque for starting the air-conditioning compressor. The appropriate output torque can better realize the starting of the air-conditioning compressor and protect the reliability of the air-conditioning compressor.

[0105] Specifically, the standard open-loop starting current can be the minimum open-loop starting current required for the air-conditioning compressor to start, and the limit open-loop starting current is the maximum open-loop starting current corresponding to the start of the air-conditioning compressor. It can be set based on the preliminary test of the compressor and combined with the actual application scenario to protect the reliability of the operation of the air-conditioning compressor. Through the influence of the lubricating oil viscosity parameters on the open-loop starting current, the target open-loop starting current suitable for the current outdoor temperature environment and the static time can be determined. For example, the standard open-loop starting current can be set to 5A, and the limit open-loop starting current can be set to 10A.

[0106] For example, the target open-loop starting current may be determined by the following formula according to the viscosity parameter of the lubricating oil and the standard open-loop starting current and the limit open-loop starting current corresponding to the air-conditioning compressor, including:

[0107] I=I0+(I lim -I0)*γ, I0≤I≤I lim

[0108] Among them, I is used to represent the target starting current, I0 is used to represent the standard open-loop starting current, and I lim It is used to indicate the limit open-loop starting current, and γ is used to indicate the viscosity parameter of the lubricating oil.

[0109] In this embodiment, the range of the open-loop starting current is scaled according to the lubricating oil viscosity parameter so that the determined target open-loop starting current can be maintained within [I0, I lim ] range, ensuring the reliability of starting the air-conditioning compressor.
