[0002] Temperature control equipment, especially air conditioning and heating systems, plays a vital role in modern building environments to ensure the comfort of indoor environments. Among them, the compressor, as the core component of temperature control equipment, is used to adjust the output of cold and hot sources to meet the temperature requirements set by users, thereby improving the user's equipment experience.

Figure 2 As shown, the compressor frequency limiting control method of the temperature control device may include the following operations:

[0084] 201. During the operation of the compressor, target parameters of the temperature control device are obtained.

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

[0086] In the embodiment of the present invention, when the judgment result is yes, step 203, step 206-step 207 are executed; when the judgment result is no, step 204-step 207 are executed.

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

[0088] In the embodiment of the present invention, optionally, the electrical parameter threshold value can be determined according to device characteristic information (such as device type, device usage information, etc.), working environment information, etc. of the temperature control device.

When it is determined that the device electrical parameter is less than the electrical parameter threshold, predict the operating temperature change parameter of the temperature control device according to the device electrical parameter, and determine whether the operating temperature change parameter is greater than or equal to a preset operating temperature change threshold.

[0090] In the embodiment of the present invention, optionally, the operating temperature change threshold value can be determined based on device characteristic information (such as device type, device usage information, etc.), working environment information, load change information, etc. of the temperature control device.

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

[0092] 206. When it is determined that the frequency limit control condition is met, determine the frequency limit control parameters of the compressor.

[0093] 207. Perform frequency limiting control operation on the compressor according to the frequency limiting control parameters of the compressor.

[0094] In the embodiment of the present invention, for other descriptions of step 201, step 206 and step 207, please refer to the detailed description of step 101 to step 103 in the first embodiment, and the embodiment of the present invention will not be repeated.

[0095] It can be seen that the implementation of the embodiment of the present invention can determine whether the compressor is in a working condition requiring frequency limiting control based on the equipment electrical parameters of the temperature control device and the operating temperature change parameters. In this way, the occurrence of equipment damage caused by 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 improving the stability and service life of the equipment.

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

[0097] When the target parameters of the temperature control device include the device exhaust parameters, determining the target impact corresponding to the temperature control device according to the device exhaust parameters;

[0098] According to the target impact, determine whether the temperature control equipment meets the preset normal operating conditions;

[0099] When it is determined that the normal operating conditions are not met, it is determined that the target parameters meet the frequency limiting control conditions.

[0100] In this optional embodiment, optionally, the target impact condition includes at least one of an impact condition on a condenser of the temperature control device, an impact condition on a compressor, an impact condition on a refrigerant of the temperature control device, and an impact condition on a lubricant of the temperature control device.

[0101] For example, the impact on the condenser can be understood as the specific manifestation of the condenser when it is affected by exhaust gas, such as decreased condensation efficiency, frost or ice on the condenser surface, abnormal condensation pressure, etc.; the impact on the compressor can be understood as the specific impact of exhaust gas on the performance of the compressor, such as excessive exhaust temperature may cause compressor overheating, abnormal vibration, noise, etc.; the impact on the refrigerant can be understood as the changes in the refrigerant caused by the influence of exhaust gas during use, such as increased water content, reduced dosage, deterioration, etc.; the impact on the lubricant can be understood as the changes in the lubricant caused by the influence of exhaust gas during use, such as increased water content, reduced dosage, deterioration, etc.

[0102] It can be seen that this optional embodiment can determine the specific impact of the exhaust gas on the condenser, compressor, refrigerant and lubricant according to the exhaust conditions of the temperature control equipment, and then determine whether the temperature control equipment meets the normal operating conditions based on the specific impact. In this way, the reliability and accuracy of the determination of the frequency limiting control conditions of the temperature control equipment can be comprehensively improved, thereby reducing the occurrence of component failures and quality changes of agents, thereby improving the stability of use of components and agents, extending their service life, and reducing maintenance costs.

[0103] In another optional embodiment, the above step of determining the target impact of the temperature control device according to the exhaust parameters of the device includes:

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

[0105] According to the exhaust parameters of the equipment and the first device parameters of the condenser, a first impact of the exhaust condition of the temperature control equipment on the condenser is determined as the impact on the condenser of the temperature control equipment.

Further, the first impact condition may include a first device temperature impact condition and / or a first device blockage impact condition.

[0107] It should be noted that abnormal temperature conditions of the condenser may indicate that blockage, leakage or wear and tear is about to occur or already exists inside the device, while abnormal blockage of the condenser may indicate that it is caused by impurities, moisture or oil in the exhaust gas, resulting in reduced condensation efficiency. Based on the above abnormal conditions, the compressor can be precisely frequency-limited or even shut down in the future.

[0108] It can be seen that this optional embodiment can determine the first impact of the exhaust condition of the temperature control device on the condenser based on the equipment exhaust parameters of the temperature control device and the first device parameters of the condenser. In this way, the reliability and accuracy of determining the specific impact of the exhaust condition of the temperature control device on the condenser are improved, thereby improving the identification and prediction accuracy and timeliness of fault signs of the condenser, thereby reducing the occurrence of condenser failures through frequency limiting operation of the compressor and extending the service life of the condenser.

[0109] In yet another optional embodiment, determining the target impact of the temperature control device according to the exhaust parameters of the device further includes:

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

[0111] According to the equipment exhaust parameter and the second device parameter of the compressor, a second impact condition on the compressor is determined as the impact condition on the compressor.

Further, the second influencing condition may include a second device temperature influencing condition, a second device exhaust blockage influencing condition (such as poor exhaust, increased pressure, etc.), and an exhaust valve failure influencing condition (such as valve plate breakage, jamming, leakage, etc.).

[0113] It can be seen that this optional embodiment can determine the second impact of the exhaust condition of the temperature control device on the compressor based on the equipment exhaust parameters of the temperature control device and the second device parameters of the compressor. In this way, the reliability and accuracy of determining the specific impact of the exhaust condition of the temperature control device on the compressor are improved, thereby improving the identification, prediction accuracy and timeliness of compressor failure signs, thereby reducing the occurrence of compressor failures through frequency limiting operation of the compressor, extending the service life of the compressor and reducing maintenance costs.

[0114] In yet another optional embodiment, determining the target impact of the temperature control device according to the exhaust parameters of the device further includes:

[0115] Obtaining a first dosage parameter of a condensing agent of a temperature control device;

[0116] According to the exhaust parameters of the equipment and the first agent parameters of the condensing agent, a third impact condition on the condensing agent is determined as the impact condition on the condensing agent.

[0117] In this optional embodiment, the first agent parameter optionally includes at least one of a first agent type parameter (such as the type and physical / chemical properties of the condensing agent), a first agent amount parameter (such as the filling amount and consumption amount of the condensing agent, etc.), and a first agent usage condition (such as usage history, replacement frequency, whether there is leakage, etc.). Further optionally, the third influencing condition includes at least one of a first agent chemical composition change parameter (such as whether a chemical reaction such as decomposition or oxidation occurs, etc.), a first agent temperature change parameter, a first agent gas pressure change parameter, and a first agent transmission position change parameter.

[0118] It can be seen that this optional embodiment can determine the third impact on the condensing agent based on the equipment exhaust parameters of the temperature control equipment and the first agent parameters of the condensing agent. In this way, the occurrence of damage to the temperature control equipment caused by the condensing agent problem can be reduced, and the use and management process of the condensing agent can be optimized, thereby improving the operating efficiency of the equipment, reducing energy consumption, and extending the service life of the equipment.

[0119] In yet another optional embodiment, determining the target impact of the temperature control device according to the exhaust parameters of the device further includes:

[0120] Obtaining a second agent parameter of the lubricating oil of the temperature control device;

[0121] According to the equipment exhaust parameters and the second agent parameters of the lubricating oil, a fourth impact condition on the lubricating oil is determined as the impact condition on the lubricating oil.

[0122] In this optional embodiment, the second agent parameter optionally includes at least one of a second agent type parameter (such as the type and physical / chemical properties of the lubricant), a second agent amount parameter (such as the filling amount and consumption amount of the lubricant), and a second agent usage condition (such as usage history, replacement frequency, whether there is leakage, etc.). Further optionally, the fourth influencing condition includes at least one of a second agent chemical composition change parameter (such as whether a chemical reaction such as decomposition or oxidation occurs), a second agent temperature change parameter, and a second agent transmission position change parameter.

[0123] It can be seen that this optional embodiment can determine the fourth impact on the condensing agent based on the equipment exhaust parameters of the temperature control equipment and the second agent parameters of the lubricating oil. In this way, the occurrence of damage to the temperature control equipment caused by lubricating oil problems can be reduced, and the use and management process of the lubricating oil can be optimized, thereby improving the operating efficiency of the equipment, reducing energy consumption, and further extending the service life of the equipment.
