In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling high-frequency transfer sound prevention during heating of an air conditioner, which is applied to the air conditioner, according to an exemplary embodiment, and includes the following steps:
s101, acquiring the frequency of an outdoor compressor;
step S102, judging whether the frequency of the outdoor compressor is higher than or equal to a preset high-frequency transmission sound threshold frequency, if so, performing frequency reduction operation control for preventing high-frequency transmission sound on the outdoor compressor;
and step S103, judging whether the quit condition of the frequency reduction operation control is met or not in the process of controlling the frequency reduction operation of preventing the high-frequency transmission sound of the outdoor compressor, and if so, quitting the frequency reduction operation control of preventing the high-frequency transmission sound of the outdoor compressor.
When the air conditioner is used for heating operation in winter, the user often gives feedback to hear the air conditioner indoor unit to generate high-frequency noise. The high-frequency noise is considered to be generated by the air conditioning indoor unit at one time. After the examination, the problem that high-frequency noise is generated by the outdoor unit of the air conditioner and is transmitted to the indoor unit of the air conditioner through the refrigerant pipeline, so that the high-frequency noise occurs indoors is found. Specifically, after the frequency of the outdoor compressor is increased to a certain high frequency, the outdoor compressor generates high-frequency noise, and the high-frequency noise is transmitted to the indoor unit of the air conditioner through the refrigerant pipeline, so that the problem of the high-frequency noise in the room is solved, and adverse effects are generated on the use experience of a user. In order to solve the problems, the frequency of the outdoor compressor is acquired during the heating operation process of the air conditioner, and the acquired frequency of the outdoor compressor is subjected to subsequent judgment processing. The outdoor compressor frequency may be obtained in real time or at preset time intervals, for example, the outdoor compressor frequency is obtained every few seconds.
When the frequency of the outdoor compressor is judged to be higher than or equal to the preset high-frequency transmission sound threshold frequency, the problem that the outdoor compressor can generate high-frequency noise and transmit the high-frequency noise to the indoor unit through a refrigerant pipeline is solved, and therefore the frequency reduction operation control for preventing the high-frequency transmission sound is carried out on the outdoor compressor when the frequency of the outdoor compressor is judged to be higher than or equal to the preset high-frequency transmission sound threshold frequency. Therefore, the problem that high-frequency noise generated by an outdoor compressor is transmitted to an indoor unit through a refrigerant pipeline when an air conditioner heats is solved. In the process of controlling the frequency reducing operation, when judging that the condition for quitting the frequency reducing operation control for preventing the high-frequency transmission sound is reached, quitting the frequency reducing operation control for preventing the high-frequency transmission sound from being carried out on the outdoor compressor, and therefore, the air conditioner is switched back to the normal heating operation control in time.
By the scheme, the problem that high-frequency noise is generated by an outdoor compressor and transmitted to an indoor unit through a refrigerant pipeline when the air conditioner heats and is caused to appear indoors can be solved, and the air conditioner is timely switched back to normal heating operation control through frequency reduction operation control quitting condition judgment control. Thereby being helpful to improve the use experience of the user in the aspect of noise reduction.
In one embodiment, the down-conversion operation control for preventing high frequency transfer noise of the outdoor compressor in step S102 includes:
and controlling the outdoor compressor to reduce the frequency and operate in a preset frequency range which guarantees the accelerated heating.
Specifically, the control outdoor compressor operation that reduces the frequency, if it is too much to reduce the frequency, though outdoor compressor produced high frequency noise and passed through the refrigerant pipeline and transmitted indoor set when having solved air conditioner heating, lead to the indoor problem that high frequency noise appears, nevertheless, the effect that indoor heating promoted is really not good, and indoor temperature promotes probably very slowly. Therefore, according to the scheme, the frequency range for guaranteeing the accelerated heating is set and used for guaranteeing that the indoor temperature is increased as fast as possible, the outdoor compressor is operated in the frequency range for guaranteeing the accelerated heating in a frequency reduction mode, the problem that high-frequency noise generated by the outdoor compressor is transmitted to an indoor unit through a refrigerant pipeline when an air conditioner heats is solved, and the indoor temperature can be increased as fast as possible while the problem that the high-frequency noise occurs indoors is solved.
In one embodiment, the upper limit value of the frequency range for securing the accelerated heating is smaller than the high-frequency transfer tone threshold frequency.
Specifically, based on the consideration of the control accuracy, the upper limit value of the frequency range for guaranteeing the heating acceleration can be set to be smaller than the preset high-frequency transmission sound threshold frequency, so that when the frequency reduction control is adjusted, the frequency to which the outdoor compressor is operated in a frequency reduction mode is guaranteed to be smaller than the high-frequency transmission sound threshold frequency. Meanwhile, based on the consideration of the noise sensitivity of different people, the upper limit value of the frequency range for guaranteeing the accelerated heating is set to be smaller than the preset high-frequency transmission sound threshold frequency, so that the method is suitable for users very sensitive to high-frequency noise.
In specific application, the threshold frequency of the high-frequency transmission sound can be set to be 90Hz, and when the frequency of the outdoor compressor rises to 90Hz in the heating process of the air conditioner, the outdoor compressor generates high-frequency noise which is transmitted to the indoor unit through a refrigerant pipeline, so that the problem of high-frequency noise in the room is caused. The frequency range of the heating acceleration of the guarantee can be set to be 60Hz to 80Hz (including 60Hz and 80Hz), the problem that when the problem that high-frequency noise occurs indoors, the outdoor compressor generates high-frequency noise and transmits the high-frequency noise to the indoor unit through a refrigerant pipeline when the air conditioner is used for heating is solved, and meanwhile the indoor temperature can be quickly improved. Meanwhile, the upper limit value of 80Hz is set, the threshold frequency of the high-frequency transmission sound is smaller than 90Hz, and the high-frequency noise can be ensured not to be sensed by a user who is very sensitive to the high-frequency noise.
In one embodiment, the controlling the outdoor compressor to perform the down-conversion operation in the preset frequency range for guaranteeing the accelerated heating comprises:
and determining a frequency value of the outdoor compressor in the frequency range for guaranteeing the accelerated heating according to the indoor environment temperature, wherein the lower the indoor environment temperature is, the higher the frequency value of the outdoor compressor in the frequency range for guaranteeing the accelerated heating is.
Specifically, taking the case that the outdoor compressor operates in a frequency reduction mode in the range of 60Hz to 80Hz, by the scheme, the outdoor compressor operates in a frequency reduction mode in 70Hz when the indoor temperature is 12 ℃, and operates in a frequency reduction mode in 75Hz when the indoor temperature is 6 ℃. Therefore, the problem that high-frequency noise generated by an outdoor compressor is transmitted to an indoor unit through a refrigerant pipeline when an air conditioner heats is solved, and the indoor temperature can be further and quickly increased while the problem that the high-frequency noise occurs indoors is solved.
For step S101, in an embodiment, the acquiring the outdoor compressor frequency includes:
and acquiring the indoor environment temperature, judging whether the indoor environment temperature meets the preset high-frequency transmission sound temperature judgment condition, and acquiring the frequency of the outdoor compressor if the indoor environment temperature meets the preset high-frequency transmission sound temperature judgment condition.
The above-mentioned scheme, only when satisfying the temperature judgement condition of the high-frequency transmission sound that presets, only need to carry out the control of preventing the high-frequency transmission sound to the compressor frequency when heating. For example, when the indoor temperature is lower than a certain threshold temperature, the frequency of the outdoor compressor is continuously increased to generate high-frequency noise, and the high-frequency noise is transmitted to the indoor unit through the refrigerant pipeline to cause the problem of high-frequency noise indoors.
In one embodiment, the determining whether the indoor ambient temperature meets the preset high-frequency transmission sound temperature determination condition includes:
and judging whether the indoor environment temperature is within a preset low-temperature range, and if so, judging that the indoor environment temperature meets the high-frequency transmission sound temperature judgment condition.
Specifically, if the preset low-temperature range is 5 ℃ to 15 ℃ (including 5 ℃ and 15 ℃), the indoor temperature is higher than 15 ℃, the outdoor compressor does not generate high-frequency noise when operating, the indoor temperature is lower than or equal to 15 ℃, and the outdoor compressor may generate high-frequency noise when operating, in the above embodiment, the indoor environment temperature is limited to the preset low-temperature range (5 ℃ to 15 ℃) to meet the preset high-frequency transmission sound temperature judgment condition, and the compressor frequency is not controlled to prevent high-frequency transmission sound when the indoor temperature is lower than 5 ℃, which is based on the consideration of indoor cooler, the compressor frequency needs to be heated quickly to achieve the comfort of a human body, so the compressor frequency is not controlled to prevent high-frequency transmission sound when the indoor temperature is lower than 5 ℃.
In one embodiment, the determining in step S103 whether the exit condition of the down-running control is reached includes:
and judging whether the high-frequency transmission sound temperature judgment condition is not met, and if not, reaching an exit condition of the frequency reduction operation control.
Under the scheme of the embodiment, the following specific applications can be formed: when the heating operation of the air conditioner is detected, acquiring the indoor environment temperature, judging whether the indoor environment temperature meets the preset high-frequency transmission sound temperature judgment condition, and if so, acquiring the frequency of an outdoor compressor; judging whether the frequency of the outdoor compressor is higher than or equal to a preset high-frequency transmission sound threshold frequency, if so, performing frequency reduction operation control for preventing high-frequency transmission sound on the outdoor compressor; and in the process of controlling the down-conversion operation of the outdoor compressor for preventing the high-frequency transmission sound, when the indoor environment temperature is judged to not meet the preset high-frequency transmission sound temperature judgment condition, the down-conversion operation control for preventing the high-frequency transmission sound is quitted.
In one embodiment, for step S102, when it is determined that the outdoor compressor frequency is higher than or equal to the preset high frequency transfer tone threshold frequency, the method further includes:
and acquiring an indoor unit wind shield, judging whether the indoor unit wind shield is lower than or equal to a preset threshold wind shield, and if so, performing frequency reduction operation control for preventing high-frequency transmission sound on the outdoor compressor.
In a specific application, when the indoor unit of the air conditioner runs, different sounds can be generated under different wind gears, for example, the indoor unit of the air conditioner has 7 wind gears including a super-strong gear, a high gear, a middle-low gear, a low gear and a mute gear, and the generated sounds are sequentially reduced under the 7 wind gears, the sound of the super-strong gear is the largest, and the sound of the mute gear is the smallest. When the indoor unit is operated in heating mode at a certain wind shield (such as a middle wind shield) or a wind shield below the wind shield, the sound generated by the indoor unit is small, and high-frequency noise generated by the outdoor compressor is transmitted to the indoor unit through the refrigerant pipeline, so that a user can feel obvious high-frequency noise indoors. Therefore, the wind shield can be set as a threshold wind shield, and when the indoor unit is lower than or equal to the threshold wind shield in heating operation, the frequency of the outdoor compressor is judged to be higher than or equal to the preset high-frequency transmission sound threshold frequency, and then the down-conversion operation control for preventing the high-frequency transmission sound is carried out on the outdoor compressor. When the indoor unit is operated to heat above the threshold wind level, the high-frequency noise transmitted from the outdoor unit is masked because the sound generated by the indoor unit is large, so that even if the frequency of the outdoor compressor is judged to be higher than or equal to the preset high-frequency transmission sound threshold frequency, the frequency reduction operation control for preventing the high-frequency transmission sound is not needed to be carried out on the outdoor compressor.
