Description

Technical Field

[0001] The present application relates to the field of air conditioning, and in particular, to a life alarm method, device, medium and system for a refrigerant sensor of an air conditioner. Background Art

[0002] R290, as a natural refrigerant with a GWP of 3, has high energy efficiency in air conditioners due to its good thermophysical properties. R290 has become a popular alternative refrigerant for household air conditioners. In order to meet the safe application of R290 A3 class flammable refrigerant, even household air conditioning systems with an injection volume that does not exceed the limit will be equipped with refrigerant sensors as an important function. Common R290 sensors for household air conditioners are mainly infrared absorption and semiconductor types. Among them, the infrared sensor has a life of 10 to 15 years and is relatively expensive, while the lower-cost semiconductor sensor has a life of about 5 years. The life in the specification is determined according to the general temperature and humidity, gas interference, and dust deposition environment. It lacks the ability to follow the actual operating environment. The actual life may be longer or shorter, which makes it difficult to match the service life of household air conditioners and meet the requirements of long-term reliable detection. The life of the refrigerant sensor is greatly affected by environmental factors.

[0003] In the prior art, the life alarm of the refrigerant sensor generally adopts the general practice of CN117006595A, which is judged according to whether the accumulated time of the sensor in the power-on state is greater than or equal to the working life threshold of the sensor. It neither considers the influence of the surrounding environment of the sensor nor the influence of the air conditioner operation status, and is prone to false alarms caused by the large difference between the actual life and the warning life. In this regard, CN115200181A provides a correction method for a refrigerant sensor, which corrects the detection concentration of the refrigerant sensor through the current working information such as temperature, humidity, working time, etc. detected by the sensor's own submodule to improve the detection accuracy and service life of the refrigerant sensor, but lacks correction evaluation of the influence of the fan state and air conditioner operation mode, air quality (such as dust), air humidity, etc. on the actual life caused by the superimposed surface dust and gas interference environment. CN116085938A sets at least two refrigerant sensors to realize switching between main and auxiliary sensors. CN116085939A sets a first sensor with higher detection accuracy and lifespan, and performs concentration correction on the second sensor to ensure stable performance output throughout the life cycle. Both have high costs and do not solve the large difference between actual lifespan and estimated lifespan.

[0004] That is, the existing solutions consider relatively simple factors for predicting the life of the refrigerant sensor, which results in poor accuracy in predicting the life of the refrigerant sensor. Summary of the invention

[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0045] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0046] As introduced in the background technology, in the prior art, the life alarm of the refrigerant sensor generally adopts the general practice of CN117006595A, which is judged according to whether the cumulative time of the sensor in the power-on state is greater than or equal to the working life threshold of the sensor. It neither considers the influence of the surrounding environment of the sensor nor the influence of the air conditioner operation status, and is prone to false alarms caused by the large difference between the actual life and the warning life. In this regard, CN115200181A provides a correction method for a refrigerant sensor, which corrects the detection concentration of the refrigerant sensor through the current working information such as temperature, humidity, working time, etc. detected by the sensor's own submodule to improve the detection accuracy and service life of the refrigerant sensor, but lacks correction evaluation of the influence of the actual life caused by the superimposed surface dust and gas interference environment such as the fan state and air conditioner operation mode, air quality (such as dust), air humidity, etc. CN116085938A sets at least two refrigerant sensors to realize switching between main and auxiliary sensors. CN116085939A sets a first sensor with higher detection accuracy and life, and performs concentration correction on the second sensor to ensure stable performance output throughout the life cycle. Both are relatively costly and do not solve the large difference between actual life and estimated life. In order to solve the problem that the existing solutions consider relatively single factors for predicting the life of refrigerant sensors, thereby resulting in poor accuracy in predicting the life of refrigerant sensors, the embodiments of the present application provide a life alarm method, device, medium and system for a refrigerant sensor of an air conditioner.

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0048] In this embodiment, a life alarm method for a refrigerant sensor of an air conditioner is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0049] Figure 1 FIG. 1 is a flow chart of a method for warning the life of a refrigerant sensor of an air conditioner according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0050] Step S101, obtaining the cumulative power-on time, dust accumulation operation time, interference operation time and environmental operation time of the refrigerant sensor of the air conditioner, wherein the interference operation time represents the influence of the current interference gas material environment on the life of the refrigerant sensor, and the environmental operation time represents the influence of the temperature and humidity environment on the life of the refrigerant sensor;

[0051] The cumulative power-on time in step S101 is based on Determined, among which, q i The current power-on time of the refrigerant sensor, Q 0 is the cumulative power-on time, and i is the current collection time.

[0052] The step S101 of obtaining the dust accumulation operation time of the refrigerant sensor of the air conditioner includes:

[0053] according to

[0054] Determine the above dust accumulation operation time;

[0055] Among them, Q 1 is the above dust accumulation operation time, η is the sensor cleaning index coefficient, μ is the equivalent coefficient of the fan operation time in non-cooling mode, q i is the current power-on time of the refrigerant sensor, f i is the current air conditioner fan operating time, RH i is the current relative humidity, s i is the current air quality, v is the equivalent coefficient of the fan running time in cooling mode, c i RH is the operating time in cooling mode. 0,a RH 0,b RH 0,c are respectively the first preset reference humidity, the second preset reference humidity, and the third preset reference humidity, s 0,a 、s 0,b 、s 0,c They are respectively the first preset benchmark air quality, the second preset benchmark air quality, and the third preset benchmark air quality, and n is the total number of collection moments.

[0056] Specifically, RH 0,a RH 0,b RH 0,c The reference humidity when the fan is not running, the fan is running in non-cooling mode, and the fan is running in cooling mode, respectively. 0,a 、s 0,b 、s 0,c Represents the baseline air quality when the fan is not running, the fan is running in non-cooling mode, and the fan is running in cooling mode, such as RH 0,a RH 0,b RH 0,c 80%, 70%, 60% respectively, 0,a 、s 0,b 、s 0,c They are 4, 3, and 2 respectively. i One of the following: 1, 2, 3, corresponding to different air quality, the higher the air quality, the higher the s i The smaller.

[0057] In one embodiment of the present application, the above method further includes:

[0058] After obtaining the dust accumulation operation time of the refrigerant sensor of the air conditioner, if the dust accumulation operation time is greater than or equal to the preset dust accumulation operation time, generating a dust cleaning prompt message to prompt that the refrigerant sensor needs to be cleaned;

[0059] Receive and respond to the received dust cleaning completion instruction, and reset the above dust accumulation operation time.

[0060] Specifically, the dust accumulation operation time is preset, and generally the semiconductor sensor takes a value of 10000h to 20000h. The equivalent coefficient of the fan operation time in the non-cooling mode can be taken as 0.75 to 0.9, and the equivalent coefficient of the fan operation time in the cooling mode can be taken as 0.6 to 0.7.

[0061] After the air conditioner is powered on, it detects whether its WIFI module is connected to the Internet. If so, the air quality in the online weather forecast is obtained in real time. If not, the air quality is directly assigned to the benchmark air quality. Next, the air conditioner fan operating time, the cooling mode operating time, the current humidity of the sensor and the power-on time are obtained, and the dust accumulation operating time is calculated. The dust accumulation operating time calculated in each iteration is compared with the preset dust accumulation operating time. Different sensor cleaning flag coefficients are given according to the comparison results. If the dust accumulation operating time is less than the preset dust accumulation operating time, the dust accumulation operating time is corrected and assigned according to η=1. If the dust accumulation operating time is greater than or equal to the preset dust accumulation operating time, a sensor cleaning alarm reminder fault code is issued to remind the user to clean the sensor. After the user cleans the sensor, when the sensor cleaning flag changes from 1 to 0, the dust accumulation operating time is reset according to η=0.5. If the user has not cleaned it and the sensor cleaning flag is still 1, the dust accumulation operating time is corrected and assigned according to η=1.

[0062] The step S101 of obtaining the interference operation time of the refrigerant sensor of the air conditioner includes:

[0063] according to

[0064] Determine the duration of operation of the above interference;

[0065] Among them, Q 2 is the duration of the above interference operation, q i is the current power-on time of the refrigerant sensor, λ i is the current sensor interference duration correction coefficient, and n is the total number of acquisition moments.

[0066] Refrigerant sensors, especially semiconductor refrigerant sensors, rely on gas-sensitive materials made of semiconductor metal oxide films for detection. Long-term exposure to specific pollutant gases or chemical interference substances may cause their surfaces to be covered with irreversible adsorbents, affecting the gas adsorption and desorption process and reducing the life of the sensor. As shown in Table 1, the current sensor interference duration correction coefficient values ​​are shown.

[0069] Among them, P i It is the cumulative leakage alarm duration.

[0070] In one embodiment of the present application, the above method further includes:

[0071] Get the cumulative leakage alarm duration of the refrigerant sensor;

[0072] Determine the duration ratio as the ratio of the above cumulative leakage alarm duration to the current refrigerant sensor power-on duration;

[0073] Determine the current sensor interference duration correction coefficient corresponding to the duration ratio.

[0074] Specifically, the mapping relationship between the duration ratio and the current sensor interference duration correction coefficient is set to make the interference operation duration more consistent with the actual working conditions. The influence of the current interference gas material environment on the life is evaluated by the proportion of the cumulative leakage alarm duration in the power-on duration, and the current sensor interference duration correction coefficient is obtained to correct the current interference operation duration. The iterative cumulative calculation is performed during operation to obtain the interference operation duration.

[0075] The step S101 of obtaining the ambient operating time of the refrigerant sensor of the air conditioner includes:

[0076] according to

[0077] Determine how long the above environment will run;

[0078] Among them, Q 3 is the duration of the above interference operation, q i is the current power-on time of the refrigerant sensor, κ i is the current environment correction coefficient, and n is the total number of collection moments.

[0081] t i is the current temperature.

[0082] As shown in Table 2, the value of the current environmental correction coefficient is displayed. Temperature changes can cause changes in the microstructure of the sensor material or accelerate the chemical reaction process. Changes in humidity can affect the electrical properties of the semiconductor material in the sensor, especially materials that are sensitive to moisture, and ultimately affect the life of the sensor. Generally, the refrigerant sensor has its own temperature detection and humidity detection unit. The temperature and humidity parameters detected by the sensor are used to determine the relationship between the current temperature and humidity coordinates and the preset temperature and humidity coordinates. When the corresponding current environment operation time correction coefficient is determined, the current environment operation time is corrected, and iterative cumulative calculations are performed during operation to obtain the environment operation time, and the degree of influence of the temperature and humidity environment on the sensor life is evaluated.

[0083] Step S102, determining the actual operation time as the sum of the power-on cumulative time, the dust accumulation operation time, the interference operation time and the environment operation time;

[0084] Step S103: When the actual operating time is greater than or equal to the preset life time, a life alarm message is generated to prompt that the refrigerant sensor needs to be replaced.

[0085] In the above steps, by determining the actual operating time as the sum of the above-mentioned power-on cumulative time, the above-mentioned dust accumulation operating time, the above-mentioned interference operating time and the above-mentioned environmental operating time, and when the above-mentioned actual operating time is greater than or equal to the preset life time, a life alarm message is generated to prompt the need to replace the above-mentioned refrigerant sensor, so that compared with the existing scheme, the present application considers more dust accumulation operating time, interference operating time and environmental operating time, that is, compared with the existing scheme, the factors considered are no longer single, thereby improving the life prediction accuracy of the refrigerant sensor, and further solving the problem that the existing scheme considers relatively single factors for the life prediction of the refrigerant sensor, thereby resulting in poor life prediction accuracy of the refrigerant sensor.

[0086] Regarding the preset life span, the semiconductor sensor generally takes a value of 30,000 hours to 50,000 hours. Generate a life alarm message, that is, issue a life expiration fault code to remind the user to replace the refrigerant sensor.

[0087] In one embodiment of the present application, the above method further includes:

[0088] Get the temperature and humidity of the sensor in the current environment, and get the current temperature and current relative humidity;

[0089] The corresponding current environment correction coefficient is determined according to the threshold range of the current temperature and the current relative humidity.

[0090] Specifically, by setting the mapping relationship between temperature, relative humidity and current environment correction coefficient, it is convenient to subsequently determine the corresponding current environment correction coefficient according to the threshold range of the current temperature and the current relative humidity, so that the environmental operating time is more in line with actual working conditions.

[0091] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the life alarm method of the refrigerant sensor of the air conditioner of the present application will be described in detail below in combination with specific embodiments.

[0092] This embodiment relates to a specific life alarm method for a refrigerant sensor of an air conditioner, such as Figure 2 As shown, including:

[0093] Obtain the cumulative power-on time, dust accumulation operation time, interference operation time, and environmental operation time of the air conditioner's refrigerant sensor. The interference operation time represents the degree of influence of the current interfering gas material environment on the life of the refrigerant sensor, and the environmental operation time represents the degree of influence of the temperature and humidity environment on the life of the refrigerant sensor.

[0094] After obtaining the dust accumulation operation time of the refrigerant sensor of the air conditioner, if the dust accumulation operation time is greater than or equal to the preset dust accumulation operation time, generating a dust cleaning prompt message to prompt that the refrigerant sensor needs to be cleaned;

[0095] Receive and respond to the received dust cleaning completion instruction, and reset the dust accumulation operation time;

[0096] Obtain the cumulative leakage alarm duration of the refrigerant sensor; determine the duration ratio as the ratio of the cumulative leakage alarm duration to the current refrigerant sensor power-on duration; determine the current sensor interference duration correction coefficient corresponding to the duration ratio;

[0097] Get the temperature and humidity of the sensor in the current environment, and get the current temperature and current relative humidity;

[0098] Determine the corresponding current environment correction coefficient according to the threshold range of the current temperature and the current relative humidity;

[0099] Determine the actual operating time as the sum of the accumulated power-on time, the dust accumulation time, the interference time, and the environmental time;

[0100] When the actual operating time is greater than or equal to the preset life time, a life alarm message is generated to prompt that the refrigerant sensor needs to be replaced.

[0101] When the actual operating time is less than the preset life time, it is determined that there is no need to generate life alarm information.

[0102] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
