Optionally, the method can be implemented by a compressor frequency limiting control device, which can be integrated in the compressor, or a local server or a cloud server or the like for processing a compressor frequency limiting control flow of the temperature control device, and embodiments of the present application are not limited thereto. As shown in Figure 2 The compressor frequency limiting control method of the temperature control device can include the following operations:

[0084] 201. During operation of the compressor, a target parameter of the temperature control device is acquired.

[0085] 202. When the target parameter of the temperature control device includes a device electrical parameter, it is determined whether the device electrical parameter is greater than or equal to a preset electrical parameter threshold value according to the device electrical parameter.

[0086] In embodiments of the present application, when the determination result is yes, step 203 and steps 206-207 are performed; when the determination result is no, steps 204-207 are performed.

[0087] 203. When it is determined that the device electrical parameter is greater than or equal to the electrical parameter threshold value, it is determined that the target parameter satisfies a frequency limiting control condition.

[0089] 204. When it is determined that the device electrical parameter is less than the electrical parameter threshold value, an operating temperature change parameter of the temperature control device is predicted according to the device electrical parameter, and it is determined whether the operating temperature change parameter is greater than or equal to a preset operating temperature change threshold value.

[0090] In embodiments of the present application, optionally, the operating temperature change threshold value can be determined according to device characteristic information (such as device type, device usage information, and the like) of the temperature control device, working environment information, load change information, and the like.

[0091] 205. When it is determined that the operating temperature change parameter is greater than or equal to the operating temperature change threshold value, it is determined that the target parameter satisfies a preset frequency limiting control condition.

[0092] 206. When it is determined that the frequency limiting control condition is satisfied, a frequency limiting control parameter of the compressor is determined.

[0093] 207. The compressor is subjected to frequency limiting control according to the frequency limiting control parameter of the compressor.

[0094] In the embodiments of the present application, for other descriptions of steps 201, 206 and 207, please refer to the detailed descriptions of steps 101-103 in Embodiment 1, and the embodiments of the present application will not be repeated here.

[0095] It can be seen that, by implementing the embodiments of the present application, whether the compressor is in the working condition requiring the frequency limiting control can be determined according to the equipment electrical parameter and the operating temperature change parameter of the temperature control equipment, so that the damage of the equipment caused by the overload or overheating of the compressor can be effectively reduced, and the reliability and accuracy of the frequency limiting control of the compressor can be improved, thereby the stability and service life of the equipment can be improved.

[0096] In an optional embodiment, the method further comprises:

[0097] When the target parameter of the temperature control equipment comprises an equipment exhaust parameter, the target influence situation corresponding to the temperature control equipment is determined according to the equipment exhaust parameter;

[0098] According to the target influence situation, whether the temperature control equipment meets the preset normal operating condition is determined;

[0099] When it is determined that the normal operating condition is not met, it is determined that the target parameter meets the frequency limiting control condition.

[0100] In the optional embodiment, optionally, the target influence situation comprises at least one of an influence situation of a condenser of the temperature control equipment, an influence situation of the compressor, an influence situation of a condensing agent of the temperature control equipment, and an influence situation of a lubricant of the temperature control equipment.

[0101] For example, the influence situation of the condenser can be understood as the specific performance of the condenser when the condenser is affected by the exhaust, such as a decrease in condensing efficiency, frosting or icing on the surface of the condenser, abnormal condensing pressure, etc.; the influence situation of the compressor can be understood as the specific influence of the exhaust on the performance of the compressor, such as overheating, abnormal vibration, noise, etc. of the compressor caused by the exhaust temperature being too high; the influence situation of the condensing agent can be understood as the change of the condensing agent in the use process caused by the exhaust, such as an increase in water content, a decrease in dosage, deterioration, etc.; the influence situation of the lubricant can be understood as the change of the lubricant in the use process caused by the exhaust, such as an increase in water content, a decrease in dosage, deterioration, etc.

[0102] It can be seen that the optional embodiment can determine the specific influence of the exhaust on the condenser, the compressor, the condensing agent and the lubricant according to the exhaust condition of the temperature control device, and then determine whether the temperature control device meets the normal operation condition according to the specific influence, so that the determination reliability and accuracy of the frequency limiting control condition of the temperature control device can be comprehensively improved, and the failure of the device and the quality change of the agent can be reduced, thereby the use stability and service life of the device and the agent can be improved, and the maintenance cost is reduced.

[0103] In another optional embodiment, the step of determining the target influence situation of the temperature control device according to the device exhaust parameter comprises:

[0104] Obtaining a first device parameter of the condenser of the temperature control device;

Further optionally, the first influence situation comprises a first device temperature influence situation and / or a first device blockage influence situation.

[0107] It should be noted that the abnormal temperature situation of the condenser may indicate that there is a problem of blockage, leakage or wear in the device, and the abnormal blockage situation of the condenser may be caused by impurities, moisture or oil in the exhaust, which reduces the condensing efficiency, so that the compressor can be accurately frequency limited or even stopped based on the above abnormal situation.

[0108] It can be seen that the optional embodiment can determine the first influence situation of the exhaust condition of the temperature control device on the condenser according to the device exhaust parameter of the temperature control device and the first device parameter of the condenser, so that the determination reliability and accuracy of the specific influence of the exhaust condition of the temperature control device on the condenser are improved, and the identification, prediction accuracy and timeliness of the fault signs of the condenser are improved, so that the failure of the condenser is reduced through the frequency limiting operation of the compressor, and the service life of the condenser is prolonged.

[0110] obtaining a second device parameter of the compressor;

[0111] determining a second influence condition of the compressor as the influence condition of the compressor according to the device exhaust parameter and the second device parameter of the compressor.

Further optionally, the second influence condition comprises at least one of a second device temperature influence condition, a second device exhaust blockage influence condition (such as exhaust unsmoothness, pressure rise, etc.), and an exhaust valve failure influence condition (such as a valve piece fracture, a jamming, a leakage, etc.).

[0113] It can be seen that the optional embodiment can determine the second influence condition of the compressor caused by the exhaust condition of the temperature control device according to the device exhaust parameter of the temperature control device and the second device parameter of the compressor, thereby improving the determination reliability and accuracy of the specific influence of the exhaust condition of the temperature control device on the compressor, and further improving the identification and prediction accuracy and timeliness of the fault signs of the compressor, so as to reduce the fault condition of the compressor through the frequency limiting operation of the compressor, prolong the service life of the compressor, and reduce the maintenance cost.

[0114] In yet another optional embodiment, the determining the target influence condition corresponding to the temperature control device according to the device exhaust parameter further comprises:

[0115] obtaining a first use parameter of a condensing agent of the temperature control device;

[0116] determining a third influence condition of the condensing agent as the influence condition of the condensing agent according to the device exhaust parameter and the first use parameter of the condensing agent.

[0117] In the optional embodiment, optionally, the first use parameter comprises at least one of a first use type parameter (such as a kind, a physical / chemical property of the condensing agent), a first use amount parameter (such as a filling amount, a consumption amount of the condensing agent, etc.), and a first use condition (such as a use history, a replacement frequency, whether there is a leakage, etc.).
