Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
Generally, after an air conditioner is used or placed for a period of time, dust, impurities and the like are attached to the surfaces of heat exchangers of an indoor unit and an outdoor unit, and if the heat exchangers are not cleaned in time, the heat exchange efficiency of the heat exchangers is affected, and the air quality of the indoor environment is also affected. For this reason, the air conditioner is provided with a self-cleaning function to periodically clean heat exchangers of the indoor and outdoor units.
Fig. 1 is a schematic flowchart of a method for self-cleaning control of an air conditioner according to an embodiment of the disclosure. As shown in fig. 1, the method for self-cleaning control of an air conditioner includes:
s110, after the air conditioner enters a self-cleaning mode, determining the operating parameters of the air conditioner according to the environment humidity;
and S120, controlling the air conditioner to operate according to the operation parameters, and defrosting the surface of the heat exchanger.
Specifically, after a self-cleaning control instruction sent by the terminal equipment is received, the air conditioner is controlled to enter a self-cleaning mode according to the self-cleaning control instruction; then, controlling the electronic expansion valve to reduce the temperature of the heat exchanger to be below the dew point temperature, and controlling a fan to continuously bring the moisture in the air to the surface of the heat exchanger for condensation; and further, adjusting the electronic expansion valve to reduce the surface temperature of the heat exchanger, and simultaneously closing the fan to quickly frost the surface of the heat exchanger. Here, the terminal device may be a mobile terminal such as a remote controller, or may be a wireless communication device such as a mobile phone, which is not limited by the embodiment of the present disclosure.
It should be understood that the manner of controlling the air conditioner to enter the self-cleaning mode is not limited to controlling the air conditioner to enter the self-cleaning mode according to the self-cleaning control command as described above, for example, the cleanliness of the heat exchanger may be detected, and the air conditioner may be controlled to enter the self-cleaning mode when the cleanliness is less than or equal to a preset value, where the cleanliness detection may be implemented by detecting the amount of dust and other parameters; alternatively, the air conditioner is controlled to periodically enter the self-cleaning mode in a timing manner, which is not limited by the embodiment of the disclosure.
And then, detecting the environmental humidity of the environment where the heat exchanger is located through a humidity sensor, and determining the operating parameters of the air conditioner according to the detected environmental humidity. Here, the ambient humidity is not limited to being detected by a humidity sensor as described above, and may be calculated based on parameters such as ambient temperature, wind speed, power, and the like, using a humidity algorithm, for example.
Furthermore, the air conditioner is controlled to operate according to the determined operation parameters, the rotating speed of the fan is increased by adjusting the electronic expansion valve to quickly defrost the surface of the heat exchanger, and dust, impurities and the like attached to the heat exchanger are washed by water formed by defrosting, so that the purpose of cleaning the heat exchanger is achieved.
Further, the self-cleaning strategy of the air conditioner may include a single self-cleaning mode and a multiple self-cleaning mode, wherein the multiple self-cleaning mode may include performing two or more self-cleaning. After the air conditioner starts the multi-time self-cleaning mode, the indoor unit of the air conditioner can be automatically cleaned for two times or more, and then the outdoor unit of the air conditioner can be automatically cleaned for two times or more by controlling the reversing of the four-way valve. It should be understood that the number of self-cleaning operations may be a default number of system operations, e.g., 3, 5, etc.; or the number of operation times may be preset as required, for example, 1 time, 2 times, etc.; or, whether the next self-cleaning is needed or not may be determined by the dust deposition thickness detected by the infrared sensor or the air volume of the air outlet detected by the air volume sensor, which is not limited in the embodiment of the present disclosure.
According to the technical scheme provided by the embodiment of the disclosure, after the air conditioner enters the self-cleaning mode, the operation parameters of the air conditioner are determined according to the environment humidity, the air conditioner is controlled to operate according to the operation parameters, the surface of the heat exchanger is defrosted, and the operation parameters of the air conditioner can be adaptively adjusted according to the environment humidity, so that the accurate control of the self-cleaning function of the air conditioner is realized, the defrosting is more thorough, and the user experience is improved.
In some embodiments, determining an operating parameter of the air conditioner based on the ambient humidity comprises: and determining the operating parameters of the air conditioner according to the humidity range of the environment humidity.
Specifically, after the environmental humidity is obtained, the environmental humidity may be compared with a preset humidity range, and a humidity range corresponding to the environmental humidity is selected from the preset humidity range according to a comparison result; further, the operation parameters of the air conditioner are determined according to the humidity range corresponding to the ambient humidity.
Here, the humidity range may include a first humidity range, a second humidity range, and a third humidity range, wherein the first humidity range is low humidity, and the relative humidity is 40% or less; the second humidity range is medium humidity, the relative humidity is 40% -70%, namely, the relative humidity is higher than or equal to 40% and lower than or equal to 70%; the third humidity range is high humidity, and the relative humidity is more than 70%.
Further, there is a preset correspondence between the humidity ranges and the operating parameters of the air conditioner, that is, different humidity ranges correspond to different operating parameters.
For a first humidity range below 40% relative humidity, the defrosting time is 0.2 to 1 minute, preferably 0.5 minute, the electronic expansion valve opening is 100 to 300, preferably 200, the compressor frequency is 55 to 60 hz, preferably 55 hz, and the fan speed is 300 to 500 rpm, preferably 400 rpm.
For a second humidity range with a relative humidity of 40% to 70%, the defrosting time is 1 minute to 2 minutes, preferably 1.5 minutes, the electronic expansion valve opening is 300 to 480, preferably 480, the compressor frequency is 45 Hz to 55 Hz, preferably 50 Hz, and the fan speed is 500 rpm to 700 rpm, preferably 600 rpm.
For a third humidity range with a relative humidity above 70%, the defrosting time is 2 minutes to 4 minutes, preferably 3 minutes, the opening of the electronic expansion valve is 300 to 480, preferably 480, the frequency of the compressor is 35 Hz to 45 Hz, preferably 40 Hz, and the rotating speed of the fan is 500 rpm to 700 rpm, preferably 600 rpm.
For example, assuming that the detected ambient humidity is 50% of the relative humidity, it may be determined that the humidity range in which the ambient humidity is located is the second humidity range, and thus it is determined that the defrosting time period needs to be adjusted to 1.5 minutes, the opening degree of the electronic expansion valve is adjusted to 480, the frequency of the compressor is adjusted to 50 hz, and the rotation speed of the fan is adjusted to 600 rpm.
According to the technical scheme provided by the embodiment of the disclosure, the acquired environment humidity is compared with the preset humidity range, the humidity range of the environment humidity can be determined, and the operation parameters of the air conditioner can be further determined, so that the time for selecting the operation parameters is saved, and the accuracy of selecting the operation parameters is improved.
In some embodiments, the operating parameters include one or more of a defrosting time period, an electronic expansion valve opening, a compressor frequency, a fan speed.
Specifically, after the ambient humidity is obtained, one, two or more of the defrosting time of the air conditioner, the opening of the electronic expansion valve, the frequency of the compressor and the rotating speed of the fan can be adjusted according to the humidity range of the ambient humidity. For example, when the ambient humidity is 60% of the relative humidity, four operation parameters, namely the defrosting time, the opening of the electronic expansion valve, the frequency of the compressor and the rotating speed of the fan, can be adjusted; when the ambient humidity is 80% relative humidity, the two parameters of defrosting time and compressor frequency can be adjusted on the basis of the relative humidity of 60% as described above.
It should be understood that the operation parameters of the air conditioner are not limited to the defrosting time period, the opening degree of the electronic expansion valve, the frequency of the compressor and the rotation speed of the fan as described above, for example, the deposition thickness, the air outlet volume, the coil temperature, etc. may also be included, and the embodiment of the present disclosure does not limit this.
According to the technical scheme provided by the embodiment of the disclosure, the operation parameters of the air conditioner are adjusted according to the environment humidity, different self-cleaning operation parameters can be adopted for different types of air conditioners, and therefore the intelligence of the air conditioner is improved, and the self-cleaning degree of the air conditioner is improved.
In some embodiments, the lower the humidity range in which the ambient humidity is located, the shorter the defrosting time period.
Specifically, the ambient humidity is proportional to the defrosting time, that is, the lower the humidity range of the ambient humidity is, the shorter the defrosting time is; conversely, the higher the humidity range of the environmental humidity, the longer the defrosting time. For example, when the detected ambient humidity is in the first humidity range below 40% relative humidity, the defrosting time needs to be adjusted to be as short as, for example, 0.5 minutes; and when the detected ambient humidity is in the third humidity range of 70% or more of the relative humidity, the defrosting time period needs to be adjusted to be long, for example, 3 minutes.
Optionally, in some embodiments, the lower the humidity range in which the ambient humidity is located, the smaller the electronic expansion valve opening.
Specifically, the ambient humidity is proportional to the opening of the electronic expansion valve, that is, the lower the humidity range of the ambient humidity is, the smaller the opening of the electronic expansion valve is; conversely, the higher the humidity range of the ambient humidity, the larger the opening of the electronic expansion valve. For example, when the detected ambient humidity is in a first humidity range below 40% relative humidity, the opening of the electronic expansion valve needs to be adjusted to be, for example, 200; on the other hand, when the detected ambient humidity is in the third humidity range in which the relative humidity is 70% or more, the opening degree of the electronic expansion valve needs to be increased to, for example, 480.
Optionally, in some embodiments, the lower the humidity range in which the ambient humidity is located, the higher the compressor frequency.
Specifically, the ambient humidity is inversely proportional to the compressor frequency, that is, the lower the humidity range in which the ambient humidity is located, the higher the compressor frequency; conversely, the higher the humidity range in which the ambient humidity is located, the lower the compressor frequency. For example, when the detected ambient humidity is in a first humidity range below 40% relative humidity, the compressor frequency needs to be adjusted up to, for example, 55 hz; and when the sensed ambient humidity is in a third humidity range above 70% relative humidity, the compressor frequency needs to be adjusted down to, for example, 40 hz.
Optionally, in some embodiments, the fan speed is a first fan speed when the ambient humidity is in a first humidity range; when the environment humidity is in a second humidity range, the rotating speed of the fan is the rotating speed of the second fan; when the environment humidity is in a third humidity range, the rotating speed of the fan is the rotating speed of the third fan; the first humidity range is lower than the second humidity range, the second humidity range is lower than the third humidity range, the rotating speed of the first fan is lower than that of the second fan, and the rotating speed of the second fan is equal to that of the third fan.
Specifically, when the ambient humidity is in the first humidity range below 40% relative humidity, the fan speed is the first fan speed, i.e., 300 rpm to 500 rpm, preferably 400 rpm; when the ambient humidity is in a second humidity range of 40% -70%, the fan speed is a second fan speed, i.e. 500 rpm to 700 rpm, preferably 600 rpm; when the ambient humidity is in a third humidity range with the relative humidity of more than 70%, the rotating speed of the fan is the third rotating speed of the fan, namely 500 rpm to 700 rpm, preferably 600 rpm; that is, when the ambient humidity is in the second humidity range and the third humidity range, the rotation speeds of the fans of the air conditioner are the same, that is, the rotation speed of the second fan is equal to the rotation speed of the third fan, which are both 600 rpm; and when the ambient humidity is in the first humidity range, the rotating speed of the fan of the air conditioner is slightly lower, namely the rotating speed of the first fan is smaller than that of the second fan or the third fan. It should be appreciated that the second fan speed may also be different from the third fan speed, as the case may be.
Optionally, in some embodiments, one, two or more of the defrosting time period, the opening degree of the electronic expansion valve, the frequency of the compressor and the rotating speed of the fan may be adjusted simultaneously according to the humidity range of the ambient humidity.
For example, when the detected ambient humidity is in a first humidity range below 40% of the relative humidity, the defrosting time may be adjusted to 0.5 minutes, and the opening degree of the electronic expansion valve may be adjusted to 200 at the same time; or the defrosting time can be adjusted to 0.5 minute, the opening of the electronic expansion valve is adjusted to 200, and the frequency of the compressor is adjusted to 55 Hz; alternatively, the defrosting time may be adjusted to 0.5 minute, the opening of the electronic expansion valve may be adjusted to 200, and the frequency of the compressor may be adjusted to 55 hz, and the rotation speed of the fan may be adjusted to 400 rpm, which is not limited in the embodiment of the disclosure.
According to the technical scheme provided by the embodiment of the disclosure, one, two or more of the operation parameters of the air conditioner can be adjusted at will according to needs, so that the flexibility of adjusting the operation parameters of the air conditioner is improved.
In some embodiments, the method for air conditioner self-cleaning control of fig. 1 further includes: and in the process of defrosting the surface of the heat exchanger, adjusting the operation parameters according to the ambient temperature.
Specifically, in the process of defrosting the surface of the heat exchanger, the operation parameters of the air conditioner can be adjusted by combining the ambient temperature on the basis of considering the ambient humidity. Here, the temperature range may include a first temperature range, which is a low temperature, 10 ℃ to 20 ℃, i.e., greater than or equal to 10 ℃ and less than 20 ℃, a second temperature range, and a third temperature range; the second temperature range is middle temperature, 20-30 ℃, namely higher than or equal to 20 ℃ and lower than 30 ℃; the third temperature range is high, 30 ℃ to 40 ℃, i.e. higher than or equal to 30 ℃ and lower than or equal to 40 ℃.
It should be noted that the temperature ranges below 10 ℃ and above 40 ℃ are not suitable for the self-cleaning operation of the air conditioner, and therefore, the air conditioner will not enter the self-cleaning mode when the ambient temperature is in the temperature range below 10 ℃ or in the temperature range above 40 ℃.
