Benefits of technology

[0016] In this embodiment, in response to the compressor receiving a heating start-up command, the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor are obtained. If the first ambient temperature is lower than a preset operating ambient temperature and the power-on duration is less than a preset power-on duration threshold, the first frequency amplitude of the compressor's frequency increase is determined based on the preset frequency increase relationship between the first ambient temperature, the power-on duration, and the first ambient temperature. The preset frequency increase relationship includes the relationship between the ambient temperature, the power-on duration, and the frequency amplitude at which the compressor can increase its frequency. Based on the first frequency amplitude and the compressor's current operating frequency, the compressor's operating frequency is controlled to increase. Thus, in a low-temperature environment, when the air conditioning unit is turned on for heating, the first frequency amplitude is determined from the preset frequency increase relationship using the first ambient temperature and the power-on duration. Then, based on the first frequency amplitude and the compressor's current operating frequency, the compressor's frequency is controlled to increase. This prevents rapid frequency increase during heating start-up in low-temperature environments, which could lead to a much smaller oil return volume than oil discharge volume, resulting in oil shortage in the air conditioning unit and causing wear on large surface components such as the compressor's internal flanges and rotor.

Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more specifically, to a compressor start-up control method, device, air conditioning unit, and electronic equipment. Background Technology

[0002] As the core of the entire refrigeration system, the reliability of the compressor is a crucial guarantee for the overall reliability of the refrigeration system. If the compressor is placed in a low-temperature environment for a long time, the refrigerant in the system is prone to migrate to the low-temperature side (i.e., the outdoor side). The liquid refrigerant mixes with the refrigeration oil, so that when the air conditioning unit is powered on and started, a large amount of refrigeration oil is discharged from the compressor along with the refrigerant.

[0003] Under normal circumstances, the discharged oil dissolves in the liquid refrigerant in the condenser. However, after entering the evaporator, the refrigerant oil gradually separates from the refrigerant, returning to the compressor along the pipe walls or as oil mist gas, thus completing the cycle in the refrigeration system. However, if the air conditioning unit's frequency increases rapidly, the oil return volume may be much less than the oil discharge volume, leading to oil shortage and causing wear on large surface components such as the compressor's flanges and rotor. Therefore, it is generally recommended that users power on the unit for a period after a long period of inactivity, using the compressor's electric heater to raise the temperature of the compressor lubricating oil above its saturation temperature. This ensures that less lubricating oil is discharged with the refrigerant when the unit starts, avoiding the aforementioned problem. However, if the customer cannot control the preheating time, oil shortage may still occur. Summary of the Invention

[0008] Optionally, after obtaining the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor, the method further includes: If the first ambient temperature is not less than the preset working ambient temperature, or the power-on duration is greater than the preset power-on duration threshold, the operating frequency of the compressor is controlled by the frequency modulation control mode when the temperature regulating device connected to the compressor is started. The frequency modulation control mode includes the preset control mode stored in the temperature regulating device or the control mode selected by the user.

[0009] Optionally, using the first frequency amplitude and the second frequency amplitude as target frequency amplitudes, and based on the target frequency amplitude and the current operating frequency of the compressor, controlling the compressor to increase its operating frequency includes: Determine the target operating frequency at which the compressor needs to increase its operating frequency; Determine the frequency difference between the target operating frequency and the current operating frequency; If the frequency difference is greater than the target frequency amplitude, the compressor is controlled to increase its operating frequency to the level corresponding to the target frequency amplitude.

[0010] Optionally, after determining the frequency difference between the target operating frequency and the current operating frequency, the method further includes: If the frequency difference is less than or equal to the target frequency amplitude, the compressor is controlled to increase the operating frequency corresponding to the frequency difference.

[0011] Optionally, the method further includes: When the compressor reaches a preset state, the response time of the compressor in each preset state is recorded; The interval between the state changes of the compressor between any two preset states is determined by the response time corresponding to each of the two preset states. The preset state includes one or more of the following states: The compressor is powered on; the heating start-up command is received; it is determined that the compressor needs to increase its frequency; the compressor frequency increase is completed.

[0012] According to a second aspect of the embodiments of this application, a compressor start-up control device is provided, the control device comprising: The data acquisition module is used to acquire the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor in response to the received heating start-up command; The first frequency amplitude determination module is used to determine the first frequency amplitude of the compressor frequency increase based on the first ambient temperature, the power-on duration, and the frequency increase preset relationship corresponding to the first ambient temperature if the first ambient temperature is lower than the preset working ambient temperature and the power-on duration is less than the preset power-on duration threshold; wherein the frequency increase preset relationship includes the relationship between the ambient temperature and the power-on duration and the frequency amplitude at which the compressor can increase its frequency. The operating frequency increase module is used to control the compressor to increase its operating frequency based on the first frequency amplitude and the current operating frequency of the compressor.

[0013] According to a third aspect of the embodiments of this application, an air conditioning unit is provided, the air conditioning unit comprising: Compressor and compressor start-up control device; The compressor start-up control device controls the start-up of the compressor using the compressor start-up control method as described in any of the embodiments of this application.

[0016] In this embodiment, in response to the compressor receiving a heating start-up command, the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor are obtained. If the first ambient temperature is lower than a preset operating ambient temperature and the power-on duration is less than a preset power-on duration threshold, the first frequency amplitude of the compressor's frequency increase is determined based on the preset frequency increase relationship between the first ambient temperature, the power-on duration, and the first ambient temperature. The preset frequency increase relationship includes the relationship between the ambient temperature, the power-on duration, and the frequency amplitude at which the compressor can increase its frequency. Based on the first frequency amplitude and the compressor's current operating frequency, the compressor's operating frequency is controlled to increase. Thus, in a low-temperature environment, when the air conditioning unit is turned on for heating, the first frequency amplitude is determined from the preset frequency increase relationship using the first ambient temperature and the power-on duration. Then, based on the first frequency amplitude and the compressor's current operating frequency, the compressor's frequency is controlled to increase. This prevents rapid frequency increase during heating start-up in low-temperature environments, which could lead to a much smaller oil return volume than oil discharge volume, resulting in oil shortage in the air conditioning unit and causing wear on large surface components such as the compressor's internal flanges and rotor.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] According to an embodiment of this application, an embodiment of a compressor start-up control method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0022] The compressor is connected to the air conditioning unit, such as Figure 1 The diagram shows the structure of an air conditioning unit. When the compressor is placed in a low-temperature environment for a long time, the refrigerant tends to migrate to the low-temperature side, mixing with the refrigeration oil. This causes a large amount of refrigeration oil to be discharged from the compressor along with the refrigerant when the air conditioning unit is powered on and started. If the compressor's frequency increases rapidly at this time, the oil return rate will be less than the oil discharge rate, resulting in oil shortage in the unit. However, if the compressor, which has been in a low-temperature environment for a long time, is powered on before operation, the compressor's electric heating element (not shown in the diagram) heats the oil, raising its temperature above the saturation temperature. This reduces the amount of lubricating oil discharged with the refrigerant when the compressor starts and increases its frequency. However, the duration of power-on is often uncertain.

[0023] Therefore, to address the problem of rapid compressor frequency increase and subsequent oil shortage in low-temperature environments with insufficient power-on time, this application proposes a compressor start-up control method, such as... Figure 2 As shown, the control method includes the following steps: Step S110: In response to the received heating start-up command, obtain the first ambient temperature of the environment where the compressor is located, and the power-on duration of the compressor.

[0024] The power-on time refers to the duration from when the air conditioning unit is powered on until it starts operating in heating mode. The heating start-up command refers to the start-up command of the compressor when the air conditioning unit is in heating mode.

[0025] Specifically, in response to the compressor's heating start-up command, the system acquires the first ambient temperature and power-on duration of the compressor's environment. The first ambient temperature determines whether the compressor is in a low-temperature environment, and the power-on duration determines whether the power-on duration requirement is met. Therefore, acquiring the first ambient temperature and power-on duration in response to the compressor's heating start-up command prepares the system for subsequent determinations of the ambient temperature and power-on duration.

[0026] Step S120: If the first ambient temperature is less than the preset working ambient temperature and the power-on duration is less than the preset power-on duration threshold, the first frequency amplitude of the compressor frequency increase is determined based on the first ambient temperature, the power-on duration and the preset frequency increase relationship corresponding to the first ambient temperature.

[0027] The frequency ramp-up preset relationship includes the relationship between ambient temperature, power-on duration, and the frequency range at which the compressor can ramp up. This preset relationship can be presented as a data table. It can be obtained from three experimental data sets: different ambient temperatures, different power-on durations, and the frequency range at which the compressor can ramp up. Different ambient temperatures and different compressor models are pre-obtained, and the preset relationship between ambient temperature, power-on duration, and frequency range is then derived from these experimental data sets. Alternatively, the preset relationship can be manually set based on expert experience. The preset operating ambient temperature refers to the temperature at which the compressor can rapidly ramp up its frequency while the unit continues to operate normally; for example, a preset operating ambient temperature of 3°C. In low-temperature environments, if the power-on duration reaches a preset power-on duration threshold, even if the compressor ramps up too quickly in low-temperature environments, it will not cause oil shortage problems. For example, the preset power-on duration threshold could be 2 hours. The first frequency ramp-up amplitude refers to the maximum frequency ramp-up that the compressor can achieve during its initial startup.

[0028] Specifically, if the first ambient temperature is lower than the preset operating ambient temperature and the power-on duration is less than the preset power-on duration threshold, the first frequency amplitude of the compressor's current frequency increase is determined based on the first ambient temperature, the power-on duration, and the preset frequency increase relationship corresponding to the first ambient temperature. This step realizes the judgment of the first ambient temperature and the power-on duration of the compressor. When it is determined that the compressor is in a low-temperature environment and the power-on duration is insufficient, the first frequency amplitude of the compressor's current frequency increase is determined, which is used to prepare for the subsequent steps of controlling the compressor's frequency increase.

[0029] Step S130: Based on the first frequency amplitude and the current operating frequency of the compressor, control the compressor to increase its operating frequency.

[0030] Here, operating frequency refers to the actual frequency value of the compressor, and frequency amplitude refers to the difference between the two operating frequencies before and after the increase. For example, if the compressor's operating frequency is 100Hz and the operating frequency is increased to 110Hz after the increase, the frequency amplitude is 10Hz. This example is only to illustrate the difference between operating frequency and frequency amplitude.

[0031] Specifically, based on the first frequency amplitude and the compressor's current operating frequency, the compressor's operating frequency is controlled to increase, so that the increase in the compressor's operating frequency is limited by the first frequency amplitude. This avoids the problem of the unit running out of oil due to the compressor increasing its frequency too quickly.

[0032] In this embodiment, in response to the compressor receiving a heating start-up command, the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor are obtained. If the first ambient temperature is lower than a preset operating ambient temperature and the power-on duration is less than a preset power-on duration threshold, the first frequency amplitude of the compressor's frequency increase is determined based on the preset frequency increase relationship between the first ambient temperature, the power-on duration, and the first ambient temperature. The preset frequency increase relationship includes the relationship between the ambient temperature, the power-on duration, and the frequency amplitude at which the compressor can increase its frequency. Based on the first frequency amplitude and the compressor's current operating frequency, the compressor's operating frequency is controlled to increase. Thus, in a low-temperature environment, when the air conditioning unit is turned on for heating, the first frequency amplitude is determined from the preset frequency increase relationship using the first ambient temperature and the power-on duration. Then, based on the first frequency amplitude and the compressor's current operating frequency, the compressor's frequency is controlled to increase. This prevents rapid frequency increase during heating start-up in low-temperature environments, which could lead to a much smaller oil return volume than oil discharge volume, resulting in oil shortage in the air conditioning unit and causing wear on large surface components such as the compressor's internal flanges and rotor.

[0033] In another embodiment of the application, the first frequency amplitude of the compressor frequency increase is determined based on the first ambient temperature, the power-on duration, and the frequency increase preset relationship corresponding to the first ambient temperature, including: traversing the frequency increase preset relationship corresponding to the first environment to find the first frequency amplitude corresponding to the first ambient temperature and the power-on duration.

[0034] Among them, the frequency upsampling preset relationship can be a mapping table. The first frequency amplitude corresponding to multiple power-on durations for each first ambient temperature is obtained in advance through experimental data, and then a mapping table is established between the first ambient temperature, power-on duration and first frequency amplitude.

[0035] Specifically, from the preset frequency increase relationship corresponding to the first ambient temperature, the first frequency amplitude corresponding to the first ambient temperature and power-on time is traversed to improve the efficiency of obtaining the first frequency amplitude. Furthermore, since the first frequency amplitude is obtained through experimental data, it is real and effective, thus improving the accuracy and effectiveness of compressor frequency increase control as a whole.

[0036] In another embodiment of the application, after controlling the compressor to increase its operating frequency based on the first frequency amplitude and the current operating frequency of the compressor, the method further includes: when it is detected that the compressor meets the preset conditions for another frequency increase, obtaining the actual frequency increase amplitude of the compressor's last frequency increase and the frequency increase interval duration between the last frequency increase; determining a second frequency amplitude for the compressor to increase its frequency again based on the first ambient temperature, the power-on duration, the actual frequency increase amplitude, the frequency increase interval duration, and the frequency increase preset relationship; wherein the frequency increase preset relationship includes the relationship between the actual frequency increase amplitude and the frequency increase interval duration and the frequency amplitude at which the compressor can increase its frequency again; and controlling the compressor to increase its operating frequency based on the second frequency amplitude and the current operating frequency of the compressor.

[0037] The actual frequency increase amplitude refers to the actual frequency increase amplitude of the compressor during the previous frequency increase. For example, if the operating frequency was 100Hz before the previous frequency increase amplitude and 120Hz after the previous frequency increase amplitude, then the actual frequency increase amplitude of the previous frequency increase amplitude was 20Hz.

[0038] Specifically, when the compressor meets the preset conditions for another frequency increase, the actual frequency increase amplitude of the compressor's previous frequency increase and the frequency increase interval between the current moment and the previous frequency increase are obtained. Based on the first ambient temperature, power-on duration, actual frequency increase amplitude, frequency increase interval duration, and the preset frequency increase relationship, the second frequency amplitude for the compressor's next frequency increase is determined, that is, the upper limit of the frequency amplitude that the compressor can increase in the current time is obtained. Then, based on the second frequency amplitude and the compressor's current operating frequency, the compressor's operating frequency is controlled to increase. This application adds a step of another frequency increase based on the aforementioned embodiments. When the frequency is increased again, the second frequency amplitude is determined from the preset frequency increase relationship based on the actual frequency increase amplitude, frequency increase interval duration, power-on duration, and the first ambient temperature, so that the upper limit of the frequency increase for the next frequency increase is limited, thereby controlling the compressor's frequency increase amplitude and avoiding the problem of oil shortage in the air conditioning unit due to the compressor's excessively fast frequency increase speed.

[0039] In another embodiment of the application, based on the first ambient temperature, the power-on duration, the actual frequency increase amplitude, the frequency increase interval duration, and the frequency increase preset relationship, the second frequency amplitude for the compressor to increase its frequency again is determined, including: traversing from the frequency increase preset relationship corresponding to the first ambient temperature to find the second frequency amplitude corresponding to the power-on duration, the actual frequency increase amplitude, and the frequency increase interval duration, wherein in the frequency increase preset relationship, the second frequency amplitude at which the compressor can increase its frequency is different for different frequency increase interval durations and different actual frequency increase amplitudes.

[0040] In this embodiment, a second frequency amplitude corresponding to the power-on duration, actual frequency increase amplitude, and frequency increase interval duration is obtained by traversing the preset frequency increase relationship corresponding to the first ambient temperature. Since the preset frequency increase relationship is established in advance and is based on experimental data, the efficiency and accuracy of obtaining the second frequency amplitude are improved when traversing the preset frequency increase relationship, thereby making the control of compressor frequency increase faster and more accurate.

[0041] In another embodiment of the application, the compressor is determined to meet the preset conditions for re-increasing frequency by the following steps: detecting the second ambient temperature of the environment in which the temperature regulating device connected to the compressor is located; if the second ambient temperature is less than the set temperature of the temperature regulating device, it is determined that the compressor meets the preset conditions.

[0042] Temperature control devices refer to devices used to regulate ambient temperature, such as air conditioning units. The second ambient temperature refers to the temperature of the environment in which the temperature control device is located. The set temperature can refer to the temperature set by the user in the temperature control device. For example, the set temperature is 26℃.

[0043] Specifically, the system detects the second ambient temperature of the environment in which the temperature control device connected to the compressor is located. If this second ambient temperature is lower than the set temperature of the temperature control device, it indicates that the ambient temperature in which the temperature control device is located is lower than the set temperature. This confirms that the compressor meets the preset conditions and needs to be frequency-increased again. This solution achieves the determination of the preset conditions for frequency re-increase.

[0044] In another embodiment of the application, after controlling the compressor to increase its operating frequency, the method further includes: if the second ambient temperature of the environment in which the temperature regulating device connected to the compressor is located is not less than the set temperature of the temperature regulating device, controlling the operating frequency of the compressor by means of the frequency modulation control mode when the temperature regulating device is started, wherein the frequency modulation control mode includes a preset control mode stored in the temperature regulating device or a control mode selected by the user.

[0045] The preset control mode stored in the temperature control device can be the control mode set at the factory that corresponds to the current set temperature. The control mode selected by the user can be any one of the multiple control modes set at the factory that the user chooses.

[0046] Specifically, when the ambient temperature of the environment where the temperature regulator is located is not lower than the set temperature of the temperature regulator, the operating frequency of the compressor is controlled by the frequency modulation control method used when the temperature regulator is started. For example, when the user sets a set temperature and a target control method when the air conditioning unit is turned on for heating, after controlling the compressor to increase its operating frequency, if it is determined that the ambient temperature of the environment where the temperature regulator is located is not lower than the set temperature of the temperature regulator, the compressor frequency is controlled to increase again through the target control method, thereby bringing the ambient temperature to the set temperature. This solution enables control of the compressor's operating frequency through frequency modulation control when the ambient temperature is not lower than the set temperature. This makes the control more flexible, no longer limited by the amplitude of the first or second frequency, reduces the time required to control the compressor's operating frequency, and improves the user experience.

[0047] In another embodiment of the application, after obtaining the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor, the method further includes: if the first ambient temperature is not less than the preset working ambient temperature, or the power-on duration is greater than the preset power-on duration threshold, controlling the operating frequency of the compressor through the frequency modulation control mode when the temperature regulating device connected to the compressor is started, wherein the frequency modulation control mode includes a preset control mode stored in the temperature regulating device or a control mode selected by the user.

[0048] The preset operating ambient temperature can be 3℃, and the preset power-on time threshold can be 2 hours. Of course, the preset operating ambient temperature and preset power-on time threshold need to be set according to the actual situation, such as the model and performance of the air conditioning unit, the model or performance of the compressor, etc.

[0049] In this application, the first ambient temperature is not lower than the preset operating ambient temperature, or the power-on time is greater than the preset power-on time threshold. That is, the compressor operates in a suitable environment or has sufficient power-on time. When the compressor operates in a suitable environment, the discharged oil dissolves in the liquid refrigerant in the condenser. However, after entering the evaporator, the refrigerant oil gradually separates from the refrigerant, returning to the compressor along the pipe wall or as oil mist gas, thus completing the cycle in the refrigeration system. With sufficient power-on time, the compressor's electric heating element heats the lubricating oil above its saturation temperature during this period, ensuring that less lubricating oil is discharged with the refrigerant when the unit starts, avoiding oil shortage problems. The compressor's frequency increase rate at this time does not affect the return flow of the lubricating oil. Therefore, the compressor's operating frequency can be controlled by the frequency adjustment control method during startup using a temperature regulation device connected to the compressor, eliminating the limitation on the compressor's frequency increase range, making the entire control process faster and improving the user experience.

[0050] In another embodiment of the application, the first frequency amplitude and the second frequency amplitude are used as target frequency amplitudes. Based on the target frequency amplitude and the current operating frequency of the compressor, the compressor is controlled to increase its operating frequency, including: determining a target operating frequency at which the compressor needs to increase its operating frequency; determining a frequency difference between the target operating frequency and the current operating frequency; and if the frequency difference is greater than the target frequency amplitude, controlling the compressor to increase its operating frequency corresponding to the target frequency amplitude.

[0051] The target operating frequency can refer to the operating frequency corresponding to the set temperature. The set temperature refers to the ambient temperature of the area to be regulated. For example, if the unit is an air conditioning unit, and the user sets the ambient temperature of the area to be regulated by the air conditioning unit, such as 20°C and the set temperature is 25°C, then the target operating frequency of the compressor corresponding to 25°C needs to be determined.

[0052] Specifically, the target operating frequency for the compressor needs to be determined, and the frequency difference between the target operating frequency and the current operating frequency is determined. For example, when the air conditioning unit starts up in heating mode, i.e., when the compressor first needs to increase its operating frequency, the current operating frequency of the compressor is zero; therefore, the frequency difference is the target operating frequency. If the frequency difference is greater than a first frequency amplitude, the compressor is controlled to increase its operating frequency to the level corresponding to the first frequency amplitude. This application achieves the limitation of the compressor's increased operating frequency amplitude, enabling the unit to operate normally in low-temperature environments and under conditions of insufficient power-on time, thereby avoiding the problem of oil shortage caused by excessively high compressor operating frequency increases.

[0053] In another embodiment of the application, after determining the frequency difference between the target operating frequency and the current operating frequency, the method further includes: if the frequency difference is less than or equal to the target frequency amplitude, controlling the compressor to increase the operating frequency corresponding to the frequency difference.

[0054] Specifically, if the frequency difference is less than or equal to the first frequency amplitude, it means that the frequency difference is less than or equal to the upper limit of the frequency amplitude that can be increased at present. Controlling the compressor to increase the operating frequency corresponding to the frequency difference will not cause the unit to run out of oil.

[0055] In another embodiment of the application, the method further includes: when the compressor reaches a preset state, recording the response time of the compressor in each preset state; determining the interval duration of the state change of the compressor between two preset states by using the response time corresponding to each of any two preset states; wherein, the preset state includes one or more of the following states: the compressor is powered on; the heating start-up command is received; it is determined that the compressor needs to increase its frequency; the compressor frequency increase ends.

[0056] Specifically, the response time of the compressor in each preset state is recorded. By measuring the duration between the response times of any two preset states, the interval duration between the two preset states can be determined. In this way, the power-on duration or frequency increase interval duration can also be determined.

[0057] In another embodiment of the application, such as Figure 3 As shown, an embodiment in a specific scenario is proposed. Technical terms that are the same as or similar to those in the foregoing embodiments will not be repeated.

[0081] Furthermore, in this embodiment of the application, the apparatus further includes: The first operating frequency control module is used to, when detecting that the compressor meets the preset conditions for another frequency increase, obtain the actual frequency increase amplitude of the compressor's last frequency increase and the frequency increase interval duration between the last frequency increase; based on the first ambient temperature, the power-on duration, the actual frequency increase amplitude, the frequency increase interval duration, and the frequency increase preset relationship, determine the second frequency amplitude for the compressor to increase its frequency again; wherein, the frequency increase preset relationship includes the relationship between the actual frequency increase amplitude and the frequency increase interval duration and the frequency amplitude at which the compressor can increase its frequency again; and based on the second frequency amplitude and the compressor's current operating frequency, control the compressor to increase its operating frequency.

[0082] Furthermore, in this embodiment of the application, the apparatus further includes: The re-frequency increase condition determination module is used to determine whether the compressor meets the preset conditions for re-frequency increase through the following steps: detecting the second ambient temperature of the environment in which the temperature regulation device connected to the compressor is located; if the second ambient temperature is less than the set temperature of the temperature regulation device, determining that the compressor meets the preset conditions.

[0083] Furthermore, in this embodiment of the application, the apparatus further includes: The second operating frequency control module is used to control the operating frequency of the compressor if the second ambient temperature of the environment where the temperature regulating device connected to the compressor is located is not less than the set temperature of the temperature regulating device, by means of the frequency modulation control mode when the temperature regulating device is started. The frequency modulation control mode includes the preset control mode stored in the temperature regulating device or the control mode selected by the user.

[0084] Furthermore, in this embodiment of the application, the apparatus further includes: The third operating frequency control module is used to control the operating frequency of the compressor by means of a frequency modulation control mode when the temperature regulating device connected to the compressor starts if the first ambient temperature is not less than the preset operating ambient temperature, or the power-on duration is greater than the preset power-on duration threshold. The frequency modulation control mode includes a preset control mode stored in the temperature regulating device or a control mode selected by the user.

[0085] Furthermore, in this embodiment of the application, the first frequency amplitude and the second frequency amplitude are used as the target frequency amplitude, and the device further includes: The third operating frequency control module is used to control the compressor to increase its operating frequency based on the target frequency amplitude and the compressor's current operating frequency. The third operating frequency control module is also used to determine the target operating frequency at which the compressor needs to increase its operating frequency; determine the frequency difference between the target operating frequency and the current operating frequency; and if the frequency difference is greater than the target frequency amplitude, control the compressor to increase its operating frequency to the level corresponding to the target frequency amplitude.

[0086] Furthermore, in this embodiment of the application, the apparatus further includes: The operating frequency determination module is used to control the compressor to increase the operating frequency corresponding to the frequency difference if the frequency difference is less than or equal to the target frequency amplitude.

[0088] In this embodiment, in response to the compressor receiving a heating start-up command, the first ambient temperature of the environment where the compressor is located and the power-on duration of the compressor are obtained. If the first ambient temperature is lower than a preset operating ambient temperature and the power-on duration is less than a preset power-on duration threshold, the first frequency amplitude of the compressor's frequency increase is determined based on the preset frequency increase relationship between the first ambient temperature, the power-on duration, and the first ambient temperature. The preset frequency increase relationship includes the relationship between the ambient temperature, the power-on duration, and the frequency amplitude at which the compressor can increase its frequency. Based on the first frequency amplitude and the compressor's current operating frequency, the compressor's operating frequency is controlled to increase. Thus, in a low-temperature environment, when the air conditioning unit is turned on for heating, the first frequency amplitude is determined from the preset frequency increase relationship using the first ambient temperature and the power-on duration. Then, based on the first frequency amplitude and the compressor's current operating frequency, the compressor's frequency is controlled to increase. This prevents rapid frequency increase during heating start-up in low-temperature environments, which could lead to a much smaller oil return volume than oil discharge volume, resulting in oil shortage in the air conditioning unit and causing wear on large surface components such as the compressor's internal flanges and rotor.
