[0044] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the 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 implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0045] In the related art, in a temperature control system, the compressor in a heat pump unit uses a mechanical bearing. Since the mechanical bearing generates frictional losses during use, the energy efficiency ratio of the compressor will be reduced.

[0046] To overcome this technical problem, in an exemplary embodiment of the present disclosure, a magnetic levitation temperature regulation system is provided. In the magnetic levitation temperature regulation system, the compressor in the magnetic levitation heat pump unit 20 uses a magnetic levitation bearing, which can reduce frictional losses and improve the energy efficiency ratio of the compressor.

[0047] In an exemplary embodiment of the present disclosure, a magnetic levitation temperature regulation system is provided, as Figure 1 shown Figure 1 shows a schematic diagram of the magnetic levitation temperature regulation system provided by the exemplary embodiment of the present disclosure. The magnetic levitation temperature regulation system 100 includes a control unit 10 and a magnetic levitation heat pump unit 20.

[0048] The control unit 10 is configured to determine the operating parameters of the magnetic levitation heat pump unit 20 according to the current state parameters of the magnetic levitation heat pump unit 20 in the operating state, so as to dynamically adjust the operating mode of the magnetic levitation heat pump unit 20;

[0049] The magnetic levitation heat pump unit 20 is configured to operate according to the operating mode determined by the control unit 10.

[0050] The control unit 10 communicates with the magnetic levitation heat pump unit 20, determines the operating parameters of the magnetic levitation heat pump unit 20 based on the currently acquired status parameters of the magnetic levitation heat pump unit 20, and dynamically adjusts the operating mode of the magnetic levitation heat pump unit 20 according to the determined operating parameters, so that the magnetic levitation heat pump unit 20 operates according to the determined operating mode. The current status parameters may include any parameters capable of determining the operating parameters of the magnetic levitation heat pump unit 20. For example, it may include the current operating temperature of the magnetic levitation heat pump unit 20, the pressure of the refrigerant in the magnetic levitation heat pump unit 20, the rotational speed of the compressor in the magnetic levitation heat pump unit 20, the suction pressure of the magnetic levitation heat pump unit 20, and the discharge pressure of the magnetic levitation heat pump unit 20, etc.

[0051] In one example, the control unit 10 acquires the current status parameters of the magnetic levitation heat pump unit 20, such as the current operating temperature, the pressure of the refrigerant, the rotational speed of the compressor, the suction pressure, and the discharge pressure. The current operating status of the magnetic levitation heat pump unit 20 is determined based on the acquired current status parameters. For example, the acquired current status parameters are input into a neural network model, and the neural network model outputs the operating parameters suitable for the current operating status of the magnetic levitation heat pump unit 20, so as to dynamically adjust the operating mode of the magnetic levitation heat pump unit 20.

[0052] In an exemplary embodiment of the present disclosure, the control unit 10 monitors the operating status of the magnetic levitation heat pump unit 20 in real time, and dynamically adjusts the operating mode of the magnetic levitation heat pump unit 20 based on the current operating status of the magnetic levitation heat pump unit 20, so as to ensure that the coefficient of performance of the magnetic levitation heat pump unit reaches the optimal value.

[0053] In an exemplary embodiment of the present disclosure, the magnetic levitation heat pump unit 20 includes any one of a magnetic levitation compressor 1 and a refrigerant circulation unit that are communicated with each other. The refrigerant circulation unit can make the refrigerant circulate to complete the energy transfer;

[0054] The control unit 10 includes a controller and sensors (not shown in the figure) provided on the magnetic levitation compressor 1 and the refrigerant circulation unit; the controller is signal-connected to the sensors and is used to acquire the current status parameters of each component in the refrigerant circulation unit and the magnetic levitation compressor 1;

[0055] Reference Figure 2 , Figure 2 shows a schematic diagram of each part included in the magnetic levitation heat pump unit 20. The magnetic levitation heat pump unit 20 includes a magnetic levitation compressor 1 and a refrigerant circulation unit. The refrigerant circulation unit includes a connected evaporator 2, a condenser 3, an economizer 4, and a throttling mechanism; wherein the magnetic levitation compressor 1 is communicated with the evaporator 2 and the condenser 3, so that the refrigerant can form a circulation path between the refrigerant circulation unit and the magnetic levitation compressor 1.

[0056] The refrigerant circulation unit also includes an energy exchange device fixed on the evaporator 2 and the condenser 3 for exchanging energy with the user end. The energy exchange device can be any device that can realize energy exchange with the evaporator 2 and the condenser 3, such as a heat exchanger.

[0057] In one example, heat exchange is used as an example to illustrate Figure 2 The working process of the magnetic suspension heat pump unit 20 is shown in FIG. Figure 2 As shown, the refrigerant circulation unit includes an evaporator 2, a condenser 3, an economizer 4 and a throttling mechanism connected to each other, wherein the low-temperature and low-pressure gaseous refrigerant is sent from the evaporator 2 to the magnetic levitation compressor 1, and after being compressed by the magnetic levitation compressor 1 to form a high-temperature and high-pressure gaseous refrigerant, it is sent to the condenser 3. The high-temperature and high-pressure gaseous refrigerant passes through the condenser 3 and is re-condensed into liquid refrigerant after passing through the heat exchanger to supply heat to the client. The liquid refrigerant flows back to the evaporator 2 through the economizer 4 and the throttling mechanism to complete the cycle.

[0058] The throttling mechanism may be any component that can achieve the throttling function, for example, the throttling mechanism may include an electronic expansion valve. Figure 2 In the exemplary embodiment given, two electronic expansion valves are provided, namely a first electronic expansion valve 5 provided between the condenser 3 and the economizer 4, and a second electronic expansion valve 6 provided between the economizer 4 and the evaporator 2, so as to achieve expansion cooling of the liquid refrigerant, thereby achieving a state in which the refrigerant can continue to be circulated.

[0059] Economizer 4 can be any heat exchange device that absorbs heat through throttling evaporation of the refrigerant itself so that another part of the refrigerant is supercooled. In one example, the condenser 3 and the economizer 4 can be connected through two independent connecting pipelines, and the economizer 4 is also connected to the magnetic levitation compressor 1. The liquid refrigerant will be divided into two parts by two independent connecting pipelines and enter the economizer 4. Before entering the economizer 4, one part of the liquid refrigerant will enter the economizer 4 after expansion and cooling through the first electronic expansion valve 5, and cool the other part of the liquid refrigerant in the economizer 4. After flowing out of the economizer 4, this part of the cooled liquid refrigerant will flow through the second electronic expansion valve 6 to continue to expand and cool, and reach a state of continued recycling, and then enter the evaporator 2 for recirculation. In this cycle, the liquid refrigerant that previously flowed through the first electronic expansion valve 5 is converted into a gaseous state in the process of cooling the other part of the liquid refrigerant flowing into the economizer 4 in the economizer 4. This part of the gaseous refrigerant will enter the compressor to complete the air replenishment and enthalpy increase of the compressor.

[0060] In an exemplary embodiment, the magnetic levitation heat pump unit 20 further includes a refrigeration mechanism. The refrigeration mechanism can be any device capable of providing a cooling medium to cool the equipment. The refrigeration mechanism is connected to the magnetic levitation compressor 1 and is used to cool the magnetic levitation bearing of the magnetic levitation compressor 1. The magnetic levitation bearing of the magnetic levitation compressor 1 can be an active magnetic levitation bearing.

[0061] The refrigerant circulation unit further includes a hot gas bypass valve 7. The hot gas bypass valve 7 is connected in series in the connecting pipeline of the refrigerant circulation unit and is used to prevent the evaporator 2 from frosting.

[0062] In Figure 2 In the given exemplary embodiment, the hot gas bypass valve 7 is arranged between the condenser 3 and the evaporator 2 to send the high-temperature and high-pressure gaseous refrigerant in the condenser 3 into the evaporator 2 to prevent the evaporator 2 from frosting under low-load operation. It should be noted here that when the evaporator 2 is not in a low-load operation condition, the hot gas bypass valve 7 is in a closed state.

[0063] In an exemplary embodiment, the refrigeration mechanism can include a power component, a cooling pipeline, and any one kind of refrigerant. The power component can be any device capable of providing a thrust to the refrigerant to enable the refrigerant to circulate. In this embodiment, the power component adopts a circulation pump 9.

[0064] The circulation pump 9 is connected to the condenser 3, the magnetic levitation compressor 1, and the evaporator 2 through the cooling pipeline, and the refrigerant is sealed in the cooling pipeline. The refrigerant flows through the magnetic levitation compressor 1 under the action of the circulation pump 9 to cool it. After absorbing the heat of the magnetic levitation compressor 1, the refrigerant will vaporize and enter the evaporator 2 for heat exchange, so that the refrigerant is completely vaporized and then enters the condenser 3 to be re-condensed into a liquid refrigerant to continue flowing through the magnetic levitation compressor 1 to cool it.

[0065] In an exemplary embodiment, the control unit 20 can also regulate the start-up and shutdown phases of the magnetic levitation heat pump unit 20 to enable the magnetic levitation heat pump unit 20 to start or stop smoothly and prevent the magnetic levitation heat pump unit 20 from being damaged.

[0066] Before startup, the control unit 20 obtains the current state parameters of the magnetic levitation heat pump unit 20 through the sensors set on the refrigerant circulation unit, adjusts the parameters according to the current state parameters, and controls the startup of the magnetic levitation heat pump unit 20 through the controller; when shutting down, the controller controls the magnetic levitation compressor 1 to gradually reduce the frequency or intensity of the stator magnetic field, so that the induced current generated by the rotor cutting the magnetic induction line gradually decreases, realizing a smooth decrease in the rotational speed of the magnetic levitation compressor 1, where the frequency linearly decreases from the current value to 10 Hz; at the same time, the electronic expansion valve closes, and the magnetic levitation compressor 1 pumps the refrigerant into the condenser 3. At this time, the low-pressure side pressure ≥ 0.2 MPa; subsequently, the coil current in the magnetic levitation compressor 1 gradually drops to zero, and the rotor softly lands on the protection bearing. At this time, cutting off the power supply can complete the shutdown.

[0067] In an exemplary embodiment, referring to Figure 2 , the magnetic levitation heat pump unit 20 further includes a frequency conversion mechanism. The frequency conversion mechanism can be any frequency conversion device capable of adjusting the rotational speed of the magnetic levitation compressor 1. In this embodiment, the frequency conversion mechanism adopts a frequency conversion cabinet 8, and the frequency conversion cabinet 8 is signal-connected to the controller and the magnetic levitation compressor 1. The frequency conversion cabinet 8 adjusts the rotational speed of the magnetic levitation compressor 1 according to the load of the magnetic levitation compressor 1. In this embodiment, the magnetic levitation compressor 1 adopts wide-frequency speed regulation, and the frequency range is 20 Hz - 120 Hz.

[0068] It should be added here that the circulation pump 9 is also connected to the frequency conversion cabinet 8 through the refrigeration pipeline to cool the frequency conversion cabinet 8.

[0069] In an exemplary embodiment, the control unit 10 further includes a communication module and an energy-saving optimization module. The communication module enables the magnetic levitation heat pump unit 20 to be networked for real-time monitoring and control, and uploads the operation parameter data of the magnetic levitation heat pump unit 20 to the cloud for storage.

[0070] The energy-saving optimization module can dynamically adjust the operation parameters of the magnetic levitation heat pump unit 20 based on the real-time parameters and historical operation data of the magnetic levitation heat pump unit 20 through machine learning algorithms. For example, the energy-saving module can be a neural network model. The neural network model can be trained through the historical operation data of the magnetic levitation heat pump unit 20, so that the neural network model can output the operation parameters of the magnetic levitation heat pump unit 20 according to the current state parameters of the magnetic levitation heat pump unit 20. By using the neural network model to perform real-time training on the historical data and dynamic learning, the control unit 10 can accurately output the operation parameters of the magnetic levitation heat pump unit 20 according to the current state parameters of the magnetic levitation heat pump unit 20.

[0071] By setting up a communication module, the operation parameter data of the magnetic levitation heat pump unit 20 can be uploaded to the cloud for storage, so as to be used later. While avoiding data loss, relevant data can be stored in real time and used as the historical data of the magnetic levitation heat pump unit 20 for the energy-saving optimization module, such as a neural network model, for dynamic learning to improve the accuracy of the operation parameters output by the magnetic levitation heat pump unit 20.

[0072] In an exemplary embodiment, a control method for a magnetic levitation temperature regulation system is provided, which is applied to the magnetic levitation temperature regulation system, and the magnetic levitation temperature regulation system can be the magnetic levitation temperature regulation system in the above embodiments. Refer to Figure 3 , Figure 3 An exemplary illustration of the control method of the magnetic levitation temperature regulation system is shown, and the control method may include:

[0073] S110. In the operating state, the control unit 10 determines the operation parameters of the magnetic levitation heat pump unit 20 according to the current state parameters of the magnetic levitation heat pump unit 20, so as to dynamically adjust the operation mode of the magnetic levitation heat pump unit 20.

[0074] S120. Control the operation of the magnetic levitation heat pump unit 20 according to the operation mode.

[0075] In step S110, the operating state is the working state of the magnetic levitation heat pump unit 20. In the working state, the current state parameters of the magnetic levitation heat pump unit 20 can be obtained, and the current state parameters are input into the neural network model, and the operation parameters of the magnetic levitation heat pump unit 20 are output after being trained by the neural network model.

[0076] The current state parameters can include any parameters that can determine the operation parameters of the magnetic levitation heat pump unit 20. For example, it can include the current operating temperature of the magnetic levitation heat pump unit 20, the pressure of the refrigerant in the magnetic levitation heat pump unit 20, the rotational speed of the compressor in the magnetic levitation heat pump unit 20, the suction pressure of the magnetic levitation heat pump unit 20, and the discharge pressure of the magnetic levitation heat pump unit 20, etc.

[0077] In an exemplary embodiment, the control method further includes:

[0078] Using the historical parameter data of the magnetic levitation heat pump unit 20 to train the neural network model.

[0079] In one example, the current state parameters of the magnetic levitation heat pump unit 20, such as the current operating temperature, the pressure of the refrigerant, the speed of the compressor, the suction pressure, and the exhaust pressure, are obtained. The current operating state of the magnetic levitation heat pump unit 20 is determined by the obtained current state parameters, for example, the obtained current state parameters are input into the neural network model, and the operating parameters suitable for the current operating state of the magnetic levitation heat pump unit 20 are output through the neural network model, so that the operating mode of the magnetic levitation heat pump unit 20 can be dynamically adjusted.

[0080] When using the historical parameter data of the magnetic levitation heat pump unit 20 for training, the historical parameter data of the magnetic levitation heat pump unit 20 can be processed to eliminate irrelevant parameter data, and the effective parameter data can be input into the neural network model for training. The neural network model can be trained using the historical parameter data to obtain the operating parameters corresponding to the optimal performance coefficient COP under different effective parameters. After the current state parameters of the magnetic levitation heat pump unit 20 are obtained and input into the neural network model, the neural network model can output the corresponding optimal performance coefficient, and then the corresponding operating parameters of the magnetic levitation heat pump unit 20 can be determined.

[0081] The operation mode may also include a high temperature mode, a low temperature mode and a normal mode. When the magnetic levitation heat pump unit 20 is in operation, the temperature of the magnetic bearing of the magnetic levitation heat pump unit 20 can be obtained in real time, compared with a given threshold, and the corresponding operation mode is determined according to the comparison result. For example, the upper limit and lower limit of the ambient temperature of the operation of the magnetic levitation bearing can be preset. When it is detected that the ambient temperature exceeds the upper limit, it is determined to be a high temperature mode; when the ambient temperature is lower than the lower limit, it is determined to be a low temperature mode; when the ambient temperature is between the upper limit and the lower limit, it is determined to be a normal mode.

[0082] When the operation mode is high temperature mode, the speed of the magnetic suspension compressor 1 can be increased, and the auxiliary cooling fan can be turned on to reduce the temperature of the magnetic suspension bearing. When the operation mode is low temperature mode, the hot gas bypass valve 7 can be enabled to prevent frost on the evaporator 2. It should be added here that when the frequency conversion cabinet 8 and the operation mode generate a command conflict on the speed adjustment of the magnetic suspension compressor 1, the command adjustment of the operation mode is executed first.

[0083] In an exemplary embodiment, reference Figure 4 , Figure 4 The control method of the magnetic suspension temperature adjustment system is shown as an example, and the control method may include:

[0084] S210, obtaining the current temperature of the magnetic bearing of the magnetic suspension compressor 1;

[0085] S220: In response to the current temperature being within a preset range, determining that the magnetic suspension temperature adjustment system is in operation.

[0086] In step S210, in order to determine the operating state of the magnetic levitation heat pump unit 20, the current temperature of the magnetic levitation bearing can be obtained, and according to the current temperature situation, it can be determined whether the magnetic levitation unit 20 is in an operating state.

[0087] In step S220, the preset range includes a first preset threshold and a second preset threshold. The first preset threshold and the second preset threshold can be set according to actual needs. For example, the first preset threshold can be 40°C, and the second preset threshold can be 20°C. When the temperature of the magnetic levitation bearing is within the preset range, it indicates that the magnetic levitation heat pump unit 20 is in a normal temperature state, and this state can be defined as an operating state. Furthermore, the magnetic levitation heat pump unit 20 can be monitored in real time and the operating mode can be adjusted according to the normal operating state.

[0088] When the temperature of the magnetic levitation bearing is not within the preset range, the operating environment of the magnetic levitation heat pump unit 20 is in a low-temperature or high-temperature state, then the corresponding operating mode needs to be started to adjust the temperature of the magnetic levitation bearing. A control method of the magnetic levitation temperature regulation system is shown in an exemplary embodiment, and the control method may include:

[0089] In response to the current temperature being greater than the first preset threshold, start the precooling mode to control the cooling valve to open and cool the active magnetic levitation bearing; or,

[0090] In response to the current temperature being less than the second preset threshold, start the preheating mode to heat the active magnetic levitation bearing by the temperature generated by the operation of the magnetic levitation compressor.

[0091] When the current temperature is greater than the first preset threshold, it indicates that the temperature of the magnetic levitation bearing is relatively high and in a high-temperature state, then the precooling mode needs to be turned on. In the precooling mode, control the cooling valve to open and cool the magnetic levitation bearing.

[0092] When the current temperature is less than the second preset threshold, it indicates that the temperature of the magnetic levitation bearing is relatively low and in a low-temperature state, then the preheating mode needs to be turned on. In the preheating mode, control the magnetic levitation compressor 1 to turn on. In the current on state, the magnetic levitation compressor 1 is not energized with the magnetic levitation bearing, and the temperature generated by the operation of the magnetic levitation compressor 1 is used to heat the magnetic levitation bearing. When the magnetic levitation bearing reaches the preset range, it can operate normally, that is, it is in an operating state.

[0093] In an exemplary embodiment, the control method further includes:

[0094] According to the climate prediction data and the user usage inertia data, determine the load demand of the magnetic levitation heat pump unit 20 to determine the start-up and shutdown times of the magnetic levitation heat pump unit 20.

[0095] Based on climate prediction data and user usage habit data, the load demand of the magnetic levitation heat pump unit 20 can be determined, and then the start and stop times of the magnetic levitation heat pump unit 20 can be determined. The climate prediction data can be obtained according to weather forecasts, and the user usage habit data can be determined based on relevant data under the user's historical usage habits. For example, during the low electricity consumption period and at night when the temperature is relatively low, cold storage can be started in advance to reduce electricity costs and the user's waiting time, and improve the user experience.

[0096] Each module in the above-mentioned magnetic levitation heat pump unit 20 can be implemented in whole or in part by software, hardware, and their combination. Each of the above modules can be embedded in or independent of the processor in the computer device in the form of hardware, or stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to each of the above modules.
