The singular form of the term "one", "this" can also include the plural form.

[0051] At present, the conventional air conditioner needs to carry out intermediate frequency oil return before the compressor operates normally, and then gradually increases the frequency of the compressor. However, the compressor needs a long time of preheating to start in a cold state, which affects the use effect of the air conditioner.

[0052] To this end, the application provides a compressor winding preheating control method, an air conditioner and a storage medium.

[0053] Referring to the accompanying Figure 1 , Figure 1 is a main step flow diagram of the compressor winding preheating control method according to an embodiment of the application.

[0054] As Figure 1 shown, the compressor winding preheating control method in the embodiment of the application mainly includes the following steps S10-S30.

[0055] Step S10: Obtain current environment information, which includes outdoor environment temperature, first indoor temperature and first indoor humidity.

[0056] The current environment information refers to the surrounding environment information related to the operation of the compressor, which can include temperature, humidity and other parameters of the outdoor and indoor environment, and is used to evaluate the environmental conditions of the compressor operation.

[0057] Step S20: Determine the preheating current of the compressor winding based on the current environment information.

[0058] The preheating current refers to the current size used for heating the winding, and the purpose is to make the lubricating oil reach the appropriate fluidity, so as to protect the compressor and ensure the smooth start of the compressor.

[0059] Step S30: Preheat the compressor winding based on the preheating current.

[0060] Based on the above steps S10-S30, first, the current environment information is obtained, which includes outdoor environment temperature, first indoor temperature and first indoor humidity; the preheating current of the compressor winding is determined based on the current environment information; and the compressor winding is preheated based on the preheating current. By obtaining the current environment information (such as outdoor environment temperature, first indoor temperature and first indoor humidity), the working conditions of the compressor at the time of start can be more accurately judged, and the preheating strategy can be adjusted according to the actual situation, so as to avoid mechanical wear or failure caused by cold start, thereby improving the reliability and service life of the compressor. In addition, it can ensure the smooth start of the compressor, speed up the system to reach the set temperature, and improve the user's experience.

[0061] The above steps S10-S30 are further described below.

[0062] For step S10, in one specific embodiment of the application, before obtaining the current environment information, the compressor is in a stopped state.

[0063] Specifically, in the constant temperature and humidity air conditioning control, when the indoor temperature or the indoor humidity reaches a certain threshold value, the air conditioner will stop running and be in a stop state. The accidental start-up during system detection and adjustment can be prevented, thereby protecting the equipment from damage and ensuring the safety of the operators.

[0064] For example, in the refrigeration mode, when the absolute value of the temperature difference between the indoor temperature and the preset temperature threshold is less than or equal to 2 degrees, the compressor stops running; for example, in the heating mode, when the absolute value of the temperature difference between the indoor temperature and the preset temperature threshold is less than or equal to 2 degrees, the compressor stops running; for example, in the dehumidification mode, when the absolute value of the difference between the indoor humidity and the preset humidity threshold is less than or equal to 5, the compressor stops running.

[0065] The above is a further description of S10, and S20 will be described in detail.

[0066] In one specific embodiment of the present application, the determination of the preheating current of the compressor winding based on the current environment information comprises: determining a first temperature difference between the first indoor temperature and a preset temperature threshold; when the absolute value of the first temperature difference is within a first temperature range, obtaining a first preset current; and taking the first preset current as the preheating current of the compressor winding.

[0067] The preset temperature threshold can be a value obtained in advance according to experiments, and can be adaptively adjusted according to different use scenarios. For example, in the refrigeration mode, 22 degrees, 23 degrees, 24 degrees, etc. can be used as examples of the preset temperature threshold.

[0068] The first preset current is a pre-set current value used as a standard for preheating the compressor winding. For example, the first preset current can be a small current provided to the compressor, and the preheating power can be between 5W and 10W.

[0069] The first temperature difference is the difference between the first indoor temperature and the preset temperature threshold.

[0070] The first temperature range is a pre-set temperature range, which can be adaptively adjusted according to different use scenarios. For example, [1 degree, 1.5 degrees] can be used as an example of the first temperature range.

[0071] Specifically, first, a first temperature difference between the first indoor temperature and a preset temperature threshold is determined, and when an absolute value of the first temperature difference is within a first temperature range, a small current is provided to the compressor, and a preheating power of the small current can be between 5W and 10W. The small current preheating can help the lubricating oil of the compressor to warm up and reduce its viscosity, so that the compressor is easier to start and the pressure and impact during starting are reduced. In addition, by preheating the winding of the compressor, the wear and potential damage risk caused by cold starting can be reduced, which helps to prolong the overall service life of the compressor and reduce the maintenance cost.

[0072] In one specific embodiment of the present application, the determination of the preheating current of the compressor winding based on the current environment information comprises: determining a first humidity difference between the first indoor humidity and a preset humidity threshold; when an absolute value of the first humidity difference is within a first humidity range, a second preset current is obtained; and the second preset current is used as the preheating current of the compressor winding.

[0073] The preset humidity threshold can be a value obtained in advance according to experiments, and can be adaptively adjusted according to different use scenarios.

[0074] The second preset current is a pre-set current value used as a standard for preheating the compressor winding. For example, the second preset current can be a small current provided to the compressor, and the preheating power can be between 5W and 10W.

[0075] The first humidity difference is the difference between the first indoor humidity and the preset humidity threshold.

[0076] The first humidity range is a pre-set humidity range, and can be adaptively adjusted according to different use scenarios. For example, [3.5, 4] can be used as an example of the first humidity range.

[0077] Specifically, first, a first humidity difference between the first indoor humidity and a preset humidity threshold is determined, and when an absolute value of the first humidity difference is within a first humidity range, a small current is provided to the compressor, and a preheating power of the small current is between 5W and 10W. The small current preheating can help the lubricating oil of the compressor to warm up and reduce its viscosity, so that the compressor is easier to start and the pressure and impact during starting are reduced. In addition, by preheating the motor winding of the compressor, the wear and potential damage risk caused by cold starting can be reduced, which helps to prolong the overall service life of the compressor and reduce the maintenance cost.

[0078] In an embodiment of the present application, the determining the preheating current of the compressor winding based on the current environment information comprises: determining a second temperature difference between the first indoor temperature and a preset temperature threshold; starting a first preset working mode when an absolute value of the second temperature difference is within a second temperature range; determining a third temperature difference between the outdoor environment temperature and the first indoor temperature in the first preset working mode; and obtaining the preheating current based on a product of the third temperature difference and a first correction coefficient.

[0079] The second temperature difference is a difference between the first indoor temperature and a preset temperature threshold. In an embodiment, the first temperature difference can be the second temperature difference.

[0080] The second temperature range is a preset temperature range, which can be adaptively adjusted according to different use scenarios. For example, [2 degrees, 2.5 degrees] can be taken as an example of the second temperature range.

[0081] The first preset working mode can be any one of a heating mode or a cooling mode.

[0082] The third temperature difference is a difference between the outdoor environment temperature and the first indoor temperature.

[0083] The first correction coefficient is a value obtained in advance according to experiments. For example, 0.0025, 0.0030, 0.0035, etc. can be taken as examples of the first correction coefficient.

[0084] Specifically, when an absolute value of a difference between the first indoor temperature and a preset temperature threshold is within a second temperature range, a heating or cooling working mode is started, and the compressor is started at this time. In the working mode, a third temperature difference between the outdoor environment temperature and the first indoor temperature is calculated, and a preheating current is determined according to a product of the third temperature difference and a first correction coefficient, that is, the preheating current is a product of an absolute value of a difference between the outdoor environment temperature and the indoor environment temperature and the first correction coefficient. In this way, a more accurate preheating current can be obtained according to the outdoor environment temperature, the indoor environment temperature, and the first correction coefficient, which is beneficial to improving the preheating control efficiency of the air conditioner and improving the user experience.

[0085] In an embodiment of the present application, the determining the preheating current of the compressor winding based on the current environment information comprises: determining a second temperature difference between the first indoor temperature and a preset temperature threshold; starting a first preset working mode when an absolute value of the second temperature difference is within a second temperature range; determining a third temperature difference between the outdoor environment temperature and the first indoor temperature in the first preset working mode; and obtaining the preheating current based on a product of the third temperature difference and a first correction coefficient.

[0086] The second humidity difference is a difference between the first indoor humidity and a preset humidity threshold. In an embodiment, the first humidity difference can be the second humidity difference.

[0087] The second humidity range is a preset temperature range, which can be adaptively adjusted according to different use scenarios. For example, [5, 5.5] can be taken as an example of the second humidity range.

[0088] The second preset working mode can be a dehumidification mode.

[0089] The fourth temperature difference is a difference between an outdoor environment temperature and the first indoor temperature.

[0090] The second correction coefficient is a value obtained in advance according to experiments. For example, 0.005, 0.006, etc. can be taken as examples of the second correction coefficient.

[0091] Specifically, when an absolute value of a difference between the first indoor humidity and the preset humidity threshold is within the second humidity range, the dehumidification working mode is started, in which the fourth temperature difference between the outdoor environment temperature and the first indoor temperature is calculated, and the preheating current is determined based on a product of the fourth temperature difference and the second correction coefficient, i.e., the preheating current is a product of an absolute value of a difference between the outdoor environment temperature and the indoor environment temperature and the second correction coefficient. In this way, a more accurate preheating current can be obtained according to the outdoor environment temperature, the indoor environment temperature, and the second correction coefficient, which is conducive to improving the preheating control efficiency of the air conditioner and improving the user experience.

[0092] The above is a further description of step S20, and step S30 is further described below.

[0093] Specifically, for step S30, the preheating current determined based on the foregoing step S20 is used to preheat the compressor winding.

[0094] In an embodiment of the present application, the method further includes: obtaining a second indoor temperature; determining a fifth temperature difference between the second indoor temperature and a preset temperature threshold; and stopping preheating the compressor winding when an absolute value of the fifth temperature difference is within a third temperature range.

[0095] The second indoor temperature is an indoor temperature obtained in real time under the condition that the heating or cooling working mode is started, and the preheating current added to the compressor winding is a product of an absolute value of a difference between the outdoor environment temperature and the indoor environment temperature and the first correction coefficient.

[0096] The fifth temperature difference is a temperature difference between the second indoor temperature and the preset temperature threshold.

[0097] The third temperature range is a pre-set temperature range, which can be adaptively adjusted according to different use scenarios. For example, [1.5 degrees, 2 degrees] can be taken as an example of the third temperature range.

[0098] Specifically, in the case that the heating or cooling mode is started, and the pre-heating current added to the winding of the compressor is the product of the absolute value of the difference between the outdoor environment temperature and the indoor environment temperature and the first correction coefficient, a fifth temperature difference between the second indoor temperature and the pre-set temperature threshold is calculated, and it is further determined whether the fifth difference is within the third temperature range. If yes, it indicates that the compressor has reached a good refrigeration or heating effect, and the pre-heating of the compressor is stopped, and the compressor works normally according to the pre-set mode.

[0099] By monitoring the indoor temperature and comparing it with the pre-set temperature threshold, and stopping the pre-heating when the temperature difference reaches a certain range, unnecessary energy waste can be avoided, thereby achieving energy-saving effect. By setting the third temperature range to determine when to stop pre-heating, the system can more accurately control the pre-heating process, thereby optimizing the pre-heating effect. Through intelligent pre-heating control, the compressor can be started under the most suitable conditions, reducing the start-up delay, thereby improving the user's experience.

[0100] In one specific embodiment of the present application, the method further comprises: obtaining a second indoor humidity; obtaining a third humidity difference between the second indoor humidity and a pre-set humidity threshold; and stopping the pre-heating of the winding of the compressor when the absolute value of the third humidity difference is within a third humidity range.

[0101] The second indoor humidity is the indoor humidity detected in real time in the case that the heating or cooling mode is started, and the pre-heating current added to the winding of the compressor is the product of the absolute value of the difference between the outdoor environment temperature and the indoor environment temperature and the second correction coefficient.

[0102] The third humidity difference is the humidity difference between the second indoor humidity and the pre-set humidity threshold.

[0103] The third humidity range is a pre-set humidity range, which can be adaptively adjusted according to different use scenarios. For example, [4, 4.5] can be taken as an example of the third humidity range.

[0104] Specifically, in the case of starting the dehumidification mode and adding a preheating current to the winding of the compressor, which is the product of the absolute value of the difference between the outdoor and indoor ambient temperatures and the second correction coefficient, a third humidity difference between the second indoor humidity and the preset humidity threshold is calculated, and it is further determined whether the third humidity difference is within a third humidity range. If yes, it means that the compressor has achieved good dehumidification effect, and the preheating of the compressor is stopped, and the compressor works normally according to the preset mode.

[0105] By monitoring the indoor humidity and comparing it with the preset humidity threshold, the preheating is stopped when the humidity reaches a certain range, which can avoid unnecessary energy waste and achieve energy-saving effect. By setting the third humidity range to determine when to stop preheating, the system can more accurately control the preheating process, thereby optimizing the preheating effect. Through intelligent preheating control, the compressor can be started under the most suitable conditions, reducing the start-up delay, thereby improving the user's experience.

[0106] Figure 2 is the complete flowchart of the compressor winding preheating control method of the present application. As shown in Figure 2 , the compressor winding preheating control method can be realized by the following steps S1-S7.

[0107] S1, when the indoor temperature or humidity reaches the preset threshold, the compressor is stopped, and the current environmental information is obtained, including the outdoor ambient temperature T 外 , the first indoor temperature T 内1 and the first indoor humidity H 内1 , and further determining to execute step S2 or step S3 according to the current environmental information and the preset threshold.

[0108] S2, when |T 内1 -T1|≤1.5 degrees, the first preset current is used to preheat the winding of the compressor; or when |H 内1 -H1|≤4, the second preset current is used to preheat the winding of the compressor.

[0109] S3, when |T 内1 -T1|≥2 degrees, the refrigeration or heating mode is started, and the winding current is determined = (T 外 -T 内 )×K1, and the winding of the compressor is preheated according to the winding current to quickly warm up the compressor. At this time, the indoor temperature T 内2 (second indoor temperature) is detected, and when |T 内1 -T1|≥1.5 degrees, the following step S4 is executed.

[0110] When |H 内1When -H1|≥5, the dehumidification mode is activated, and the winding current is determined to be (T). 外 -T 内 The current is calculated as )×K2, and the compressor windings are preheated according to this winding current to allow the compressor to heat up quickly. At this time, the indoor humidity H is measured. 内2 (Second indoor temperature), when |H 内2 When -H1|≥4, then proceed to step S5 below.

[0111] S4, when |T is satisfied 内1 When -T1|≥1.5 degrees, stop preheating the compressor windings and the compressor will operate normally.

[0112] S5, when |H 内2 When -H1|≥4, preheating of the compressor windings is stopped, and the compressor operates normally.

[0113] S6, when |T 内2 When -T1|≤2 degrees, the compressor stops.

[0114] S7, when |H 内2 When -H1|≤5, the compressor stops.

[0115] By improving the cold and hot start capability of the compressor winding current, parameters such as indoor and outdoor temperature and indoor humidity are monitored in real time. When a certain threshold is reached, a preheating function is activated in advance, and a certain current is supplied to the compressor winding to preheat the compressor winding, which can improve the compressor efficiency and achieve a rapid temperature control effect.
