Referring to fig. 2, a flow chart of an embodiment of a method for detecting a filth blockage of an air conditioner filter according to the present application includes steps S201 to S204:
S201, acquiring the use duration of a filter screen corresponding to the air conditioner, the operation parameters of the air conditioner and the temperature of the inner pipe.
The filter screen use duration, that is, the accumulated use time of the filter screen, can be understood that when the air conditioner does work, the duration accumulation is started, and when the air conditioner does not do work, the duration accumulation is not performed.
It will be appreciated that the filter screen may be statistically accumulated by means of a time stamp or the like for a long period of use.
The air conditioner operation parameters, namely parameters corresponding to the air conditioner operation, specifically, the air conditioner operation parameters comprise an acting mode, a compressor frequency and a fan gear of the air conditioner, or the air conditioner operation parameters comprise an acting mode, a compressor frequency and an actual rotating speed of the air conditioner, or the air conditioner operation parameters comprise an acting mode, a compressor frequency, a fan gear and an actual rotating speed of the air conditioner; the application is not particularly limited, wherein the air conditioner working mode comprises a preset refrigeration mode and a preset heating mode.
The wind gear may be a wind gear including 1-N gears, or the wind gear may be a high wind gear, a low wind gear, a medium wind gear, etc., which is not specifically limited in the present application; it is understood that the wind speed in the air conditioner operating parameters may be a wind speed value, or a wind speed range.
Wherein the inner tube temperature, i.e., the coil temperature of the indoor heat exchanger of the air conditioner, is understood to be sensed by one or more temperature sensors mounted on the inner tube.
In an exemplary embodiment of the present application, if the indoor heat exchanger includes a plurality of temperature sensors, a plurality of initial inner tube temperatures within a preset period of time may be collected for each temperature sensor, average processing, maximum processing, or crowd processing may be performed on the plurality of initial inner tube temperatures to obtain a temperature corresponding to each temperature sensor, average processing, maximum processing, crowd processing, or the like may be performed on the temperatures corresponding to the plurality of temperature sensors to obtain an inner tube temperature.
In another embodiment of the present application, if the indoor heat exchanger includes a temperature sensor, the temperature sensor collects a plurality of initial inner tube temperatures within a preset period of time, and performs average processing, maximum processing, mass processing, or the like on the plurality of initial inner tube temperatures to obtain the inner tube temperature.
Specifically, in the embodiment of the application, the air conditioner filter screen filth blocking detection method is applied to an air conditioner filter screen filth blocking detection device, the air conditioner filter screen filth blocking detection device is arranged in an air conditioner, and after receiving an air conditioner filter screen filth blocking detection instruction, the air conditioner can acquire the filter screen use duration, the air conditioner operation parameter and the inner tube temperature corresponding to the air conditioner, or the air conditioner acquires the filter screen use duration, the air conditioner operation parameter and the inner tube temperature corresponding to the air conditioner according to the preset air conditioner filter screen filth blocking detection frequency.
S202, determining the rated inner tube temperature corresponding to the air conditioner operation parameter according to a preset mapping table and the air conditioner operation parameter.
When the rated inner tube temperature is the inner tube temperature value corresponding to the air conditioner operation parameter when the air conditioner filter screen is free of dirt blockage, the operation parameter is an air shield, and when the fan is operated in the 1 st gear, the inner tube temperature value is 35 ℃.
It can be understood that the preset mapping table includes a plurality of groups of operation parameters with mapping relation and inner tube temperature, and can be preset corresponding to different air conditioners.
Specifically, after the air conditioner detects the air conditioner operation parameters, namely, inquiring the inner tube temperature corresponding to the air conditioner operation parameters according to a preset mapping table, and obtaining the inner tube temperature as the rated inner tube temperature.
S203, determining an air quantity compensation parameter according to the rated inner tube temperature and the inner tube temperature.
The air volume compensation parameter is a parameter for compensating ventilation quantity of the filter screen, wherein the air volume compensation parameter can be an air volume value, a temperature difference value or an air volume compensation coefficient.
It can be understood that when the filter screen of the air conditioner is dirty, the ventilation quantity of the filter screen is reduced, namely, the heat exchange air quantity of the air conditioner is reduced, so that the temperature of the inner pipe is deviated from the temperature of the inner pipe when the filter screen of the air conditioner is not dirty, and the deviation is in direct proportion to the dirty degree of the filter screen; through having the rated inner tube temperature (when the filter screen is not dirty stifled) that detects current air conditioner operating parameter correspondence to confirm the amount of wind compensation parameter according to rated inner tube temperature and actual inner tube temperature, exemplary:
In one embodiment of the application, a preset mapping table (the preset mapping table represents the corresponding relation between the air volume compensation parameter and the rated inner tube temperature and the inner tube temperature) is searched for, and the air volume compensation parameter corresponding to the rated inner tube temperature and the inner tube temperature is obtained.
In another embodiment of the present application, a temperature difference between the inner tube temperature and the inner tube temperature is calculated, and the temperature difference is determined as a constant air volume compensation parameter.
S204, determining filter screen blocking parameters of the air conditioner according to the air volume compensation parameters and the filter screen use time, and outputting blocking prompt information corresponding to the blocking parameters.
The filter screen dirty and blocked parameter is a parameter representing filter screen dirty and blocked degree, and the filter screen dirty and blocked parameter can be a numerical value, so that the larger the filter screen dirty and blocked parameter is, the more serious the filter screen dirty and blocked degree is.
Specifically, after the air conditioner obtains the air volume compensation parameter according to the rated inner tube temperature and the inner tube temperature, the air volume compensation parameter and the filter screen filth blockage parameter corresponding to the filter screen using time length can be obtained by searching a preset table, the air volume compensation parameter and the filter screen using time length can be input into a preset calculation formula to be calculated, the filter screen filth blockage parameter is obtained, and it is understood that the preset calculation formula can be obtained by training and fitting; and outputting corresponding dirty blocking prompt information according to the dirty blocking parameters after the filter screen dirty blocking parameters are obtained. For example, an audible and visual alarm may be output, a short message may be sent, or a display may be performed on a display panel of the air conditioner.
Further, on the basis of the above embodiment, referring to fig. 3, fig. 3 is a schematic flow chart of another embodiment of the method for detecting filth blockage of an air conditioner filter screen according to the embodiment of the present application, including steps S301 to S307:
s301, acquiring the use time of a filter screen corresponding to the air conditioner, the operation parameters of the air conditioner and the temperature of the inner pipe.
S302, determining the rated inner tube temperature corresponding to the air conditioner operation parameter according to a preset mapping table and the air conditioner operation parameter.
S303, determining an air quantity compensation parameter according to the rated inner tube temperature and the inner tube temperature.
Wherein, the specific implementation manner of the steps S301-S303 is shown in any one of the embodiments.
S304, acquiring the environment temperature of the environment where the air conditioner is located.
Wherein the ambient temperature, i.e. the temperature of the environment of the indoor heat exchanger of the air conditioner, is understood to be detectable by at least one ambient temperature sensor.
S305, correcting the ambient temperature according to a preset temperature correction coefficient.
Specifically, the temperature correction coefficient may be preset by training according to the historical ambient temperature of the air conditioner and the historical inner tube temperature.
(1) Under certain conditions of indoor temperature (corresponding to the stable environment), the refrigerating capacity gradually decreases, the input power gradually increases and the energy efficiency ratio gradually decreases with the increase of the outdoor temperature. Under the condition that the outdoor temperature is certain, the refrigerating capacity and the input power are gradually increased along with the increase of the indoor temperature, but the increasing speed of the input power is slower than the refrigerating capacity, and the energy efficiency ratio is gradually increased as a whole; this can be achieved by: the refrigerating capacity and the indoor temperature form a certain proportional relationship and an inverse proportional relationship;
(2) In certain cases, the outdoor temperature increases with the indoor temperature, and the evaporation temperature generally increases, although in certain areas, the evaporation temperature decreases. The indoor temperature is certain, and the influence of the evaporating temperature along with the change of the outdoor temperature is not obvious, namely:
(1) the evaporation temperature theoretical rated value X (namely, the rated inner tube temperature corresponding to the operation parameter of the air conditioner) can be obtained by operating under the rated working condition (the calibrated energy efficiency).
(2) There is a positive correlation between evaporation temperature and ambient temperature, X (actual evaporator temperature) =xforehead+ (P2 RT); wherein P2 is a temperature correction coefficient, and RT is an ambient temperature.
(3) In the design process of the air conditioner, under the normal operation condition, the temperature of the inner coil pipe is close to the evaporation temperature, and IPT is approximately equal to the evaporation temperature.
