Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning control, for example, to a method and device for controlling an air-conditioning, and an air-conditioning. Background Art

[0002] As people's living standards continue to improve, smart home appliances are gradually becoming part of their lives. Currently, with users' demands for increased comfort, air conditioners have become an essential smart appliance in every household. As a crucial component of air conditioning systems, the lifespan of the compressor-pipe system is crucial to the proper functioning of the system. The compressor-pipe system's vibration originates from the compressor. After startup, the compressor transmits vibrations to the piping through the pulsating flow of refrigerant and the compressor's rotational vibrations, subjecting the piping to vibrational stress. Currently, the piping in compressor-pipe systems is mostly made of metal tubing, which is susceptible to fatigue damage over time. As fatigue damage to metal tubing increases, it shortens the lifespan of air conditioners to a certain extent. Fatigue damage refers to the process in which weaker grains in high-stress concentration areas of mechanical components subjected to alternating stress develop microcracks after a certain number of cycles, which then develop into macrocracks that continue to propagate and ultimately fracture.

[0003] Currently, in some air conditioning applications requiring strict temperature and humidity control, such as control rooms, cultural relic storage rooms, biological laboratories, and wards, unpredictable failures of air conditioning systems can cause significant losses. Therefore, how to reasonably predict and address fatigue in air conditioning piping to reduce the likelihood of failure has become a pressing technical challenge. Summary of the Invention

[0031] Figure 1 This is a schematic diagram of a method for controlling an air conditioner provided by an embodiment of the present disclosure; Figure 1 As shown, an embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0032] S11, the air conditioner determines the number of stress cycles of the piping and the average number of stress impacts of the piping each time it is shut down.

[0033] S12, the air conditioner calculates the shutdown limit number according to the stress cycle number and the average stress impact number.

[0034] S13, the air conditioner determines a life extension strategy for the air conditioner based on the number of shutdowns of its outdoor unit and the shutdown limit number.

[0035] S14, the air conditioner controls its execution of the life extension strategy.

[0036] In this solution, the air conditioner can determine the number of stress cycles for the piping and the average number of stress impacts per shutdown. The air conditioner can determine the number of stress cycles for the piping using a variety of methods. In one scenario, the air conditioner can obtain the piping's SN curve and match the number of stress cycles for the piping to the SN curve. In another scenario, the air conditioner can obtain its service life, annual operating hours, number of shutdowns per hour, and number of stress impacts per shutdown. Combining these data, the air conditioner's service life, annual operating hours, number of shutdowns per hour, and number of stress impacts per shutdown can be used to determine the number of stress cycles for the piping. In this way, the number of stress cycles for the piping can be determined using a variety of methods. It should be noted that, of the two aforementioned methods, the first method is preferred for obtaining the number of stress cycles for the piping to avoid the lower accuracy of the second method when the air conditioner is operating under poor conditions. Furthermore, the air conditioner can also obtain the average number of stress impacts per shutdown for the piping using its associated detection element. This solution allows for more accurate acquisition of the parameters required to calculate the shutdown limit.

[0037] Furthermore, after determining the number of stress cycles for the piping and the average number of stress impacts per shutdown, the air conditioner can calculate the shutdown limit by combining these two factors. Here, the shutdown limit is the quotient of the number of stress cycles and the average number of stress impacts. This approach provides an accurate data foundation for predicting the fatigue state of air conditioner piping.

[0038] Furthermore, the air conditioner can also utilize a detection element installed on the air conditioner's outdoor unit to obtain the number of shutdowns of the outdoor unit. This, combined with the number of shutdowns and the maximum number of shutdowns, can be used to reasonably predict the fatigue state of the air conditioner piping. This allows the air conditioner to select an appropriate life extension strategy based on the current fatigue state of the air conditioner piping. This allows the air conditioner to be controlled to execute the life extension strategy after determining the appropriate strategy.

[0039] The method for controlling an air conditioner, provided in an embodiment of the present disclosure, determines the number of stress cycles in the piping and the average number of stress impacts per piping shutdown; calculates the shutdown limit based on the number of stress cycles and the average number of stress impacts; and thereby determines an air conditioner life extension strategy based on the number of shutdowns of the air conditioner's outdoor unit and the shutdown limit. The air conditioner is then controlled to execute the life extension strategy. This approach allows for a reasonable prediction of the fatigue condition of the air conditioner piping based on the number of shutdowns of the air conditioner's outdoor unit and the calculated shutdown limit, thereby selecting an appropriate life extension strategy for each fatigue condition of the air conditioner piping. This extends the service life of the air conditioner piping while controlling the air conditioner to execute the life extension strategy, thereby improving the reliability of the air conditioner while reducing the probability of failure in the air conditioner system.

[0040] Figure 2 This is a schematic diagram of a method for determining the number of stress cycles provided by an embodiment of the present disclosure; Figure 2 As shown, optionally, in S11, the air conditioner determines the number of stress cycles of the piping, including:

[0041] S21, the air conditioner obtains the SN curve of the piping.

[0042] S22, the air conditioner determines the number of stress cycles of the piping according to the SN curve of the piping.

[0043] In this solution, the air conditioner can obtain the SN curve for the piping. Here, the SN curve refers to a curve that plots stress (S) against the number of stress cycles (N). The horizontal axis of the SN curve represents the number of stress cycles (N), and the vertical axis represents stress (S). This allows the air conditioner to determine the number of stress cycles for the piping after obtaining the stress. This solution allows for more accurate stress cycle counts, providing a more precise data foundation for predicting the fatigue state of the air conditioner piping.

[0044] Figure 3 is another schematic diagram of a method for determining the number of stress cycles provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, in S11, the air conditioner determines the number of stress cycles of the piping, including:

[0045] S31, the air conditioner obtains its service life, annual operating hours, hourly shutdown times, and stress shock times for each shutdown.

[0046] S32, the air conditioner determines the number of stress cycles of the piping according to its service life, annual operating hours, hourly shutdown times, and number of stress shocks during each shutdown.

[0047] It can be understood that the number of stress cycles of a piping system is closely related to its age, annual operating hours, number of downtimes per hour, and the number of stress impacts per downtime. Therefore, the air conditioner can obtain its age, annual operating hours, number of downtimes per hour, and number of stress impacts per downtime through its associated detection elements. The number of stress cycles of the piping system can be determined by combining these data with the number of years of use, annual operating hours, number of downtimes per hour, and number of stress impacts per downtime. This solution allows the determination of the number of stress cycles by obtaining the air conditioner's age, annual operating hours, number of downtimes per hour, and number of stress impacts per downtime, even when the SN curve for the air conditioner is unavailable.

[0048] Optionally, in S32, the air conditioner determines the number of stress cycles of the piping based on its service life, annual operating hours, number of shutdowns per hour, and number of stress shocks per shutdown, including:

[0049] n=y×h×t×b

[0050] Where n is the number of stress cycles, y is the number of years the air conditioner has been in use, h is the number of operating hours per year, t is the number of shutdowns per hour, and b is the number of stress shocks per shutdown.

[0051] Specifically, the number of stress cycles for the piping can be determined by multiplying the air conditioner's service life, annual operating hours, number of downtimes per hour, and number of stress shocks per downtime. This approach allows the determination of stress cycles by using the air conditioner's service life, annual operating hours, number of downtimes per hour, and number of stress shocks per downtime, even when an SN curve is unavailable.

[0052] Optionally, in S12, the air conditioner calculates a shutdown limit number based on the number of stress cycles and the average number of stress impacts, including:

[0053] P=n / a

[0054] Among them, P is the shutdown limit number, n is the number of stress cycles, and a is the average number of stress impacts.

[0055] In this solution, after determining the number of stress cycles and the average number of stress impacts for an air conditioner, the quotient of these two numbers can be used to determine the shutdown limit. This allows for a more accurate calculation of the shutdown limit by combining the stress cycles and the average number of stress impacts, providing a more precise data basis for predicting the fatigue state of air conditioner piping.

[0056] Figure 4 This is a schematic diagram of a method for determining a life extension strategy provided by an embodiment of the present disclosure; Figure 4As shown, optionally, in S13, the air conditioner determines a life extension strategy for the air conditioner based on the number of shutdowns of its outdoor unit and the shutdown limit number, including:

[0057] In step S41, the air conditioner compares the number of shutdowns of its outdoor unit with a target value determined by a shutdown limit number to obtain a comparison result.

[0058] S42: The air conditioner determines a life extension strategy for the air conditioner based on the comparison result.

[0059] In this solution, the number of shutdowns of the air conditioner outdoor unit can be obtained through the detection element associated with the air conditioner, and after the air conditioner calculates the shutdown limit number, the number of shutdowns of the air conditioner outdoor unit is compared with the target value determined by the shutdown limit number to obtain a comparison result. Specifically, multiple target values can be determined according to the shutdown limit number to divide the different fatigue levels of the air conditioning pipeline. For example, the first target value is 0.3P, the second target value is 0.5P, and the third target value is 0.9P, where P is the shutdown limit number. Furthermore, after obtaining the comparison result, the life extension strategy of the air conditioner can be determined in combination with the comparison result. With this solution, it is possible to select a suitable life extension strategy for different fatigue conditions of the air conditioning pipeline, so as to extend the service life of the air conditioning pipeline while controlling the air conditioner to execute the life extension strategy.

[0060] Optionally, in S42, the air conditioner determines a life extension strategy for the air conditioner based on the comparison result, including:

[0061] When the comparison result shows that the shutdown times of the air conditioner outdoor unit are lower than the first target value, the air conditioner determines that its life extension strategy is to maintain the current operation plan of the air conditioner.

[0062] When the comparison result shows that the number of shutdowns of the air conditioner outdoor unit is higher than the first target value, the air conditioner determines that its life extension strategy is to control the air conditioner to execute a shutdown buffer control scheme.

[0063] When the comparison result shows that the number of shutdowns of the air conditioner outdoor unit is higher than the second target value, the air conditioner determines that its life extension strategy is to reduce the number of shutdowns of the air conditioner.

[0064] When the comparison result shows that the shutdown times of the air conditioner outdoor unit are higher than the third target value, the air conditioner determines that its life extension strategy is to control the air conditioner to execute the equipment early warning plan.

[0065] The first target value is lower than the second target value, and the second target value is lower than the third target value.

[0066] In this solution, the first target value is lower than the second target value, and the second target value is lower than the third target value. As an example, the first target value is 0.3P, the second target value is 0.5P, and the third target value is 0.9P, where P is the maximum number of shutdowns. Specifically, when the comparison result shows that the number of shutdowns of the air-conditioning outdoor unit is lower than the first target value, it is determined that the air-conditioning pipeline is not fatigued, and the air-conditioning determines that its life extension strategy is to maintain the current operation plan of the air-conditioning. Here, the current operation plan of the air-conditioning refers to the start and stop time setting plan and the operation parameter setting plan of the air-conditioning. When the comparison result shows that the number of shutdowns of the air-conditioning outdoor unit is higher than the first target value, it is determined that the fatigue level of the air-conditioning pipeline is low fatigue, and the air-conditioning determines that its life extension strategy is to control the air-conditioning to execute the shutdown buffer control plan. Here, the shutdown buffer control scheme may include: obtaining the current operating frequency of the air conditioner compressor; if the current operating frequency of the compressor is below a shutdown frequency threshold, the air conditioner controls the compressor to shut down immediately; if the current operating frequency of the compressor is above the shutdown frequency threshold, the air conditioner controls the compressor to operate at a reduced frequency. This ensures that the compressor shuts down only when the load is light and the operating frequency is low, avoiding severe vibration of the compressor and its piping caused by a sudden shutdown due to a large operating frequency, pressure ratio, or pressure difference, and effectively preventing excessive stress in the compressor piping. If the comparison result shows that the number of shutdowns of the air conditioner outdoor unit exceeds the second target value, the fatigue level of the air conditioner piping is determined to be moderate, and the air conditioner determines that its life extension strategy is to reduce the number of air conditioner shutdowns. Specifically, the air conditioner can extend the pipe life by reducing the number of shutdowns per hour, thereby extending the original operating downtime. If the comparison result shows that the number of shutdowns of the air conditioner outdoor unit is above the third target value, the fatigue level of the air conditioner piping is determined to be high, and the air conditioner determines that its life extension strategy is to control the air conditioner to execute the equipment early warning scheme. Here, the equipment early warning scheme refers to the air conditioner feeding back early warning information to the user or the backend big data after-sales platform for repair confirmation. With this solution, appropriate life extension strategies can be selected according to different fatigue conditions of the air-conditioning pipes, so as to extend the service life of the air-conditioning pipes while controlling the air-conditioning to execute the life extension strategy, thereby improving the reliability of the air-conditioning while reducing the probability of failure of the air-conditioning system.

The air conditioner is then controlled to execute the life extension strategy. This solution allows for a reasonable prediction of the fatigue condition of the air conditioner piping based on the number of shutdowns of the air conditioner's outdoor unit and the calculated shutdown limit. This allows for the selection of appropriate life extension strategies based on the different fatigue conditions of the air conditioner piping. This allows the air conditioner to extend its service life while executing the life extension strategy, thereby improving the air conditioner's reliability and reducing the probability of air conditioner system failure.
