[0047] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Reference Figure 1 , shows a flow chart of steps of a control method based on a compressor provided by an embodiment of the present invention, wherein the compressor is provided with a resonant circuit, wherein the resonant circuit is composed of a coil of the compressor and a target capacitor, and the control method may specifically include the following steps:

[0049] Step 101, obtaining the operating status data of the compressor, and determining the initial resonant frequency according to the operating status data;

[0050] A resonant circuit is a circuit composed of an inductor (L) and a capacitor (C). Figure 2 As shown. The resonant circuit exhibits resonant characteristics at a specific frequency, and its basic principle is the energy exchange between inductance and capacitance.

[0051] Resonant frequency refers to the frequency at which the energy exchange between the inductor and the capacitor reaches the maximum in the resonant circuit. At a certain resonant frequency, the energy exchange between the inductor and the capacitor reaches the maximum, the circuit impedance is the minimum, and the current is the maximum.

[0052] In this embodiment, a resonant circuit is formed by the coil of the compressor and the target capacitor. The compressor can be heated by the resonant circuit to increase the temperature of the oil in the compressor and complete the startup of the compressor.

[0053] In step 101, the operating status data refers to relevant data that affects the operating status of the compressor.

[0054] In a specific implementation, the initial resonant frequency that matches the current operating state of the compressor can be determined by collecting operating status data, performing data analysis, and calculating through a preset algorithm.

[0055] In some embodiments of the present invention, the operating status data includes load data of the compressor and / or environmental data of the environment in which the compressor is located.

[0056] In some examples, the load data of the compressor may be data such as the temperature, current, and voltage of the compressor; and the environmental data of the environment in which the compressor is located may be data such as the ambient temperature and humidity.

[0057] In some embodiments of the present invention, the coils are respectively connected with a plurality of preset capacitors to form a plurality of series circuits, and a switch of each series circuit is in an open state. Before obtaining the data of the compressor and determining the initial resonant frequency according to the data, the method further includes:

[0058] Obtaining model information of the compressor;

[0059] Determining a target capacitance among the plurality of preset capacitances according to the model information;

[0060] The switch of the series circuit corresponding to the coil and the target capacitance is controlled to be closed to obtain the resonant circuit.

[0061] In this embodiment, since the parameters of compressors of different models are different, the duration of their cold start is also different, and different capacitors need to be matched. By matching the corresponding target capacitor for the compressor through the model information of the compressor, the effect of heating the compressor oil can be enhanced and the cold start time can be shortened.

[0062] Specifically, the coils of the compressor respectively form multiple series circuits with multiple preset circuits. When the target capacitance is determined, the switch of the series circuit corresponding to the control coil and the target capacitance is closed, and the series circuit also takes effect. The coil (L) and the target capacitance (C) form an LC resonant circuit.

[0063] In some embodiments of the present invention, a control system based on a compressor is also provided, which is composed of a frequency converter, a plurality of preset capacitors, a switch, a controller, and a compressor, wherein the frequency converter is responsible for converting the fixed frequency current provided by the power supply into a variable frequency output voltage, and transmitting the voltage to the power supply circuit of the compressor. The switch is used to control the connection and disconnection of each preset capacitor in the circuit, and the controller realizes dynamic frequency modulation and matching of the target capacitance by controlling the state of the switch. The controller is the core of the system, and frequency regulation and capacitor matching are realized through software algorithms. The controller can dynamically adjust the resonant frequency according to the operating status and environmental conditions of the compressor, and monitor the safety of the system to prevent overload or detuning.

[0064] For example, Figure 3 As shown, a plurality of preset capacitors (C1, C2, C3, C4) are connected in series between the phase voltage output terminal of the inverter and the port of the compressor. These preset capacitors are used to form an LC resonant circuit with the coil of the compressor, thereby generating heat through electromagnetic induction to heat the compressor.

[0065] Step 102, controlling the resonant circuit to heat the compressor according to the initial resonant frequency;

[0066] In step 102, when the initial resonant frequency is determined, the resonant circuit can be controlled to heat the compressor based on the initial resonant frequency to increase the temperature of the compressor oil, thereby allowing the compressor to be cold-started.

[0067] Step 103, in the process of controlling the resonant circuit to heat the compressor according to the initial resonant frequency, obtaining the inductance value of the coil and the capacitance value of the target capacitor;

[0068] Inductance is a physical quantity that measures the ability of an inductor (such as a coil) to store magnetic field energy. The value of inductance depends on the design and material properties of the inductor.

[0069] Capacitance is a basic parameter of capacitors, which indicates the ability of capacitors to store charge. The unit of capacitance is Farad (symbol F), but in practical applications, smaller units such as microfarad (μF), nanofarad (nF) and picofarad (pF) are often used.

[0070] In a specific implementation, the inductance value of the coil and the capacitance value of the target capacitor may be detected by a sensor.

[0071] Step 104: Update the initial resonant frequency according to the inductance value and the capacitance value to obtain a first target resonant frequency, and control the resonant circuit to heat the compressor according to the first target resonant frequency.

[0072] In step 104, the initial resonant frequency is updated by the inductance value and the capacitance value to obtain the first target resonant frequency, and the resonant circuit is controlled to heat the compressor according to the first target resonant frequency. This can achieve dynamic adjustment of the resonant frequency during heating of the compressor, so that the resonant circuit can obtain the best heating performance and the lowest energy efficiency.

[0073] In some examples, the resonant frequency fopt is calculated by the following equation (1):

[0074] fopt = 1 / 2πL×C (1)

[0075] Wherein, L is the inductance of the coil, which is determined by the properties of the coil and is generally not easy to change. C is the capacitance value. By adjusting C, the resonant frequency can be adjusted to obtain the first target resonant frequency, so that the resonant circuit heats the compressor at the optimal first target resonant frequency.

[0076] In some embodiments of the present invention, updating the initial resonant frequency according to the inductance value and the capacitance value to obtain a first target resonant frequency includes:

[0077] Obtaining the operating frequency of the compressor;

[0078] updating the capacitance value according to the inductance value and the operating frequency;

[0079] The initial resonant frequency is updated according to the inductance value and the updated capacitance value to obtain the first target resonant frequency.

[0080] The operating frequency of a compressor refers to the number of working cycles completed by the compressor per unit time, usually measured in Hertz (Hz).

[0081] In a specific implementation, assuming that the inductance value is L and the operating frequency of the compressor is fopf, the capacitance value Cmatch that needs to be updated can be obtained by the following formula (2):

[0082]

[0083] After obtaining the updated capacitance value, substitute it into formula (1) to obtain the first target resonant frequency, so as to dynamically adjust the resonant frequency according to different operating frequencies and maintain the optimal energy efficiency and heating effect of the system.

[0084] In practical applications, the dynamic frequency modulation function of the software can also be combined to further fine-tune Cmatch during actual operation to cope with instantaneous load changes and environmental changes.

[0085] In some examples, the resonant frequency can also be dynamically adjusted by monitoring the operating status of the compressor (such as temperature, load changes, etc.), as follows:

[0086] Real-time collection of compressor temperature, load (such as current, voltage, etc.) and other data. For example, the temperature sensor can continuously monitor the temperature changes of the compressor, while the current sensor is used to track the load current changes in real time to determine the actual working load of the compressor.

[0087] Further, the sensor data is transmitted to the controller, which has an embedded analysis algorithm to process the data and generate specific control signals. For example, when the temperature gradually rises or the load increases, the controller will calculate and update the operating requirements of the compressor and decide whether the frequency needs to be adjusted.

[0088] Furthermore, the controller automatically adjusts the resonant frequency based on feedback from the operating status to ensure that the frequency of the resonant circuit matches the current needs of the compressor. For example, when a high temperature or increased load is detected, the controller will increase the resonant frequency to increase the response of the resonant circuit, reduce internal resistance, and thus reduce the burden on the compressor.

[0089] Furthermore, the controller continuously monitors the effect of the adjusted resonant frequency and further adjusts parameters to maintain the compressor within the optimal operating range. For example, after the frequency is adjusted, the controller observes whether the temperature drops to the appropriate range; if the load is too high, the frequency is reduced to make the compressor run more stably.

[0090] In some examples of the present invention, a method for adjusting the resonant frequency when multiple compressors work in coordination is also provided, which is specifically as follows:

[0091] For n compressors running in parallel, the resonant frequency of each compressor satisfies the following formula (3):

[0092]

[0093] Among them, fopti is the resonant frequency of the i-th compressor, Li is the inductance value of the coil of the i-th compressor, and Cmatchi is the capacitance value corresponding to the target capacitance after matching the model information of each compressor.

[0094] The controller then dynamically adjusts fopti and Cmatchi according to the operating status of each compressor to ensure that all compressors can achieve the optimal resonance state under different operating conditions.

[0095] In some embodiments of the present invention, in the process of controlling the resonant circuit to heat the compressor according to the first target resonant frequency, a noise index value is detected in response to a control signal of a silent mode;

[0096] Obtaining a preset noise index threshold, and determining a second target resonant frequency according to the noise index threshold, the noise index value, and the first target resonant frequency;

[0097] In this embodiment, since there are some application scenarios with high requirements for noise control (such as nighttime, libraries, schools, home air conditioning, etc.), in addition to taking into account the heating effect and energy efficiency of the resonant circuit, the impact on noise also needs to be considered. The higher the resonant frequency, the greater the noise generated, so the resonant frequency needs to be further adjusted.

[0098] Silent mode is the control mode in which the compressor enters silent heating. In silent mode, the resonant circuit can maintain a better heating effect, lower energy efficiency and lower noise level. The control signal of silent mode is the control signal for entering silent mode. The control signal can be issued by the system automatically or manually by the user.

[0099] The noise index value is the noise index value of the environment where the compressor is located, which can reflect the noise level of the current environment, for example, can be expressed in decibels (db).

[0100] The noise index threshold, that is, the noise threshold value, when the noise index value is greater than or equal to the noise index threshold value, it means that the noise level of the current environment may affect people's normal life and work.

[0101] In a specific implementation, assuming that the first target frequency is fopt, the noise index threshold is Noisethreshold, and the noise index value is Noisecurrent, the second target frequency fsilent can be calculated by the following formula (4):

[0102]

[0103] Combined with further adjustment of the resonant frequency in silent mode, the noise generated by the compressor is reduced, which not only maintains the best heating effect and lower energy efficiency of the resonant circuit, but also maintains a lower noise level to avoid affecting people's normal life and work.

[0104] In practical applications, the noise index threshold can be set to 60db.

[0105] In some embodiments of the present invention, the method further comprises:

[0106] In the process of controlling the resonant circuit to heat the compressor, detecting a temperature value of the compressor;

[0107] If the temperature value of the compressor is greater than or equal to a preset temperature value, heating the compressor is stopped.

[0108] In this embodiment, the preset temperature value is the target temperature value for heating. When the temperature value of the compressor is greater than or equal to the preset temperature value, it is considered that the refrigeration oil of the compressor has been heated, the compressor can be started normally, and then the heating of the compressor is stopped.

[0109] In a specific implementation, the capacitor can be disconnected from the compressor circuit by disconnecting the switch of the compressor coil and the circuit corresponding to the target capacitor, and then the compressor enters a normal working mode.

[0110] In some examples, such as Figure 4 As shown, when the control system is started, the parameters are initialized to obtain the initial resonant frequency, the compressor is heated by the LC resonant circuit, and the oil temperature of the compressor is detected; before the oil temperature of the compressor reaches the starting temperature, the resonant frequency is dynamically adjusted by detecting the state of the compressor (such as the operating frequency, etc.); when the oil temperature of the compressor reaches the starting temperature, the resonance is stopped and the compressor enters the normal working mode.

[0111] In actual applications, since the operating temperature of the compressor oil is usually maintained between 40°C and 65°C, this temperature range can ensure that the viscosity of the oil is moderate, which can provide good lubrication effect without causing the oil performance to deteriorate due to excessively high temperature or affecting its fluidity due to excessively low temperature. Therefore, the preset temperature value can be set to 45°C, or it can be set according to actual needs.

[0112] In some embodiments of the present invention, the method further comprises:

[0113] In the process of controlling the resonant circuit to heat the compressor, detecting the current value of the compressor;

[0114] If the current value of the compressor is greater than or equal to a preset current protection value, the compressor is controlled to stop running.

[0115] In this embodiment, the preset current protection value is the current value for safe operation of the compressor. In the process of controlling the resonant circuit to heat the compressor, if it is detected that the current value of the compressor is greater than or equal to the preset current protection value, it means that the current value at this time is too large and may cause damage to the compressor. In this case, the compressor is controlled to stop running.

[0116] In actual applications, since the demagnetization values ​​(i.e., the maximum current value without damaging the compressor) of different compressor models are different, exceeding the demagnetization value may cause demagnetization and damage to the compressor. The preset current protection value is to ensure that the compressor does not enter the demagnetization state, so the preset current protection value can be set to 80% to 90% of the demagnetization value.

[0117] In practical applications, the current value of the compressor can be detected in real time, and the resonant frequency can be dynamically adjusted according to the current value to shorten the time of heating the compressor. Figure 5 As shown:

[0118] First, set a preset value and a protection value, where the protection value is greater than the preset value; if the current value is less than the preset value, it means that the current current is too low, and the resonant frequency can be increased to shorten the heating time of the compressor; if the current value is greater than the preset value but less than the protection value, the resonant frequency can be reduced to avoid further increase in current; if the current value is greater than or equal to the protection value, it is necessary to control the compressor to stop temporarily to avoid damage to the compressor.

[0119] When the system returns to normal, the compressor and the resonant circuit are restarted, and the compressor is gradually restored to normal operation through dynamic frequency modulation and capacitor matching.

[0120] The embodiments of the present invention have the following advantages: by acquiring the operating status data of the compressor and determining the initial resonant frequency according to the operating status data, the resonant circuit is controlled according to the initial resonant frequency to heat the compressor. In the process of controlling the resonant circuit to heat the compressor according to the initial resonant frequency, the inductance value of the coil and the capacitance value of the target capacitor are acquired, the initial resonant frequency is updated according to the inductance value and the capacitance value to obtain the first target resonant frequency, and the resonant circuit is controlled according to the first target resonant frequency to heat the compressor, thereby heating the compressor, thereby heating the engine oil, and accelerating the starting speed of the compressor. Moreover, by dynamically adjusting the resonant frequency, the heating effect and energy efficiency of the resonant circuit are also taken into account.
