Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of air conditioning, and in particular to an air conditioner control method, device and air conditioner. Background Art

[0002] With the advancement of science and technology, people have further improved their requirements for the cooling capacity, comfort and noise of air conditioners. In particular, the low-frequency noise generated by the operation of the outdoor unit of the air conditioner, among which the low-frequency clicking sound has a more prominent impact on people. The low-frequency clicking sound has strong penetration and will pass through the wall into the room, causing noise trouble. The reason for the low-frequency clicking sound is that after the compressor of the outdoor unit of the air conditioner is reduced to low-frequency operation, the exhaust temperature slowly decreases from high, the liquid refrigerant coming out of the evaporator gradually increases, and the amount of liquid refrigerant entering the compressor cavity slowly increases, and the pressure of the compression chamber will increase. During the operation of the compressor, when the amount of liquid refrigerant reaches a certain level, the pressure of the compression chamber will instantly increase to the critical point, making the sliding vane separation force greater than the sliding vane extrusion force, which will cause the sliding vane to separate and collide with the rotor, thereby forming a clicking sound. That is, the generation of the clicking sound can be determined as the liquid compression generated during the low-frequency operation causes the sliding vane to separate.

[0003] The experiment found that when the clicking sound occurs, the sight glass at the suction pipe is mostly foam, and the capacity is suddenly reduced. The main reason is that the lubricating oil flows into the refrigerant, which reduces the original saturation temperature of the refrigerant, increases the supercooling of the working medium, and inhibits the phase change phenomenon. At the same time, because the influx of lubricating oil increases the viscosity of the working medium, the thermal resistance of the boundary layer of the evaporator copper tube increases, which inhibits the heat exchange between the inner surface of the threaded tube and the refrigerant, resulting in a decrease in the indoor heat exchange capacity and a decrease in the suction superheat. The unevaporated foam enters the compressor suction chamber and oil pool, causing severe "cavitation phenomenon". The foam fills the entire pump body, and the vane detaches after the compressor is sucked in, producing a clicking sound.

[0004] In order to solve the problem of clicking noise, the prior art generally uses the compressor operating frequency of the air conditioner outdoor unit as a trigger condition, and then uses the compressor operating time, the compressor exhaust temperature, and the compressor operating time and exhaust temperature as three judgment conditions to determine whether to increase the operating frequency, and then obtain the final frequency control result. However, only one control parameter obtained after testing is given, that is, one machine for one use, and this logical parameter cannot be automatically adjusted to meet the operating requirements of different air conditioner outdoor units.

[0035] See also Figure 1 , Figure 1 A schematic flow chart of an air conditioner control method provided by an embodiment of the present invention;

[0036] When the air conditioner of the embodiment of the present invention is used for the first time, it is turned on and runs for a preset time (preferably 5 minutes) and then pre-executes the anti-clicking self-check process under multiple outdoor ambient temperatures (-25°C ~ 42°C), and obtains the anti-clicking program under each outdoor ambient temperature, thereby providing the anti-clicking operating parameters for the subsequent use of the air conditioner, so as to realize intelligent parameterized control to prevent low-frequency clicking noise.

[0037] The air conditioner control method according to the embodiment of the present invention comprises:

[0038] Under multiple outdoor ambient temperatures in advance, the air conditioner is controlled to execute the following anti-clicking self-check process, including steps S101 to S104.

[0039] S101, obtaining the exhaust temperature when the air conditioner produces a clicking sound during the operation of lowering the exhaust temperature, and recording it as the first exhaust temperature;

[0040] In this step, the method of detecting the clicking sound is to obtain the frequency spectrum and audio of the outdoor unit of the air conditioner during operation, upload the frequency spectrum and audio to the data center for processing, and analyze whether the clicking sound occurs.

[0041] S102: Obtain the current operating time of the air conditioner when the clicking sound occurs during the operation of the air conditioner in the low-frequency mode, and record it as the first operating time.

[0042] S103, obtaining the current operating time when the exhaust temperature is greater than or equal to the first exhaust temperature during the switching operation of the air conditioner between the low-frequency mode and the medium-frequency mode, calculating the time difference between the current operating time and the first operating time and recording it as the second operating time.

[0043] S104, storing the operating parameters of the tapping sound self-checking process at each outdoor ambient temperature as a corresponding tapping sound prevention program; which can be applied to step S105;

[0044] S105, when the air conditioner is activated, the current outdoor ambient temperature is obtained and a corresponding anti-clicking program is entered, and the operating parameters in the corresponding anti-clicking program are called to control the air conditioner to achieve anti-clicking operation.

[0045] In this embodiment, a self-test environment is pre-designed to control the air conditioner to perform the anti-clicking self-test process at multiple outdoor ambient temperatures, and different anti-clicking operating parameters at different outdoor ambient temperatures are obtained, thereby constructing an anti-clicking program corresponding to multiple outdoor ambient temperatures, so as to realize intelligent parameterized control to prevent the occurrence of low-frequency clicks when using the air conditioner. The requirements of different low-frequency bands at different outdoor ambient temperatures can be met.

[0046] In one embodiment, if Figure 2 As shown, step S101 includes:

[0047] S201, controlling the air conditioner to operate at a preset exhaust temperature;

[0048] S202, detect whether there is a clicking sound, if so, go to step S203, if not, jump to step S204;

[0049] S203, recording the preset exhaust temperature as the first exhaust temperature;

[0050] S204, after lowering the preset exhaust temperature by a preset temperature step, continue to detect whether a clicking sound occurs, if so, record the lowered current exhaust temperature as the first exhaust temperature, if not, continue to lower the temperature by a preset temperature step until a clicking sound is detected.

[0051] In this embodiment, the air conditioner is controlled to operate at a preset exhaust temperature and detects whether a clicking sound occurs. The preset exhaust temperature is preferably 40°C, which is the upper limit of the exhaust temperature when the air conditioner is prone to low-frequency clicking sounds. The lower the exhaust temperature, the more likely the clicking sound is to occur. The exhaust temperature is gradually lowered according to the preset temperature step and the exhaust temperature when the clicking sound occurs is detected to provide a basis for the design of subsequent operating parameters.

[0052] Specifically, the air conditioner is controlled to run at an exhaust temperature of 40°C for a certain period of time (the specific period is set according to actual needs, preferably 3 to 30 minutes). If no clicking sound is detected, the temperature is lowered by a preset step (preferably 1°C). That is, the air conditioner is controlled to run at an exhaust temperature of 39°C for a certain period of time and detects whether a clicking sound occurs, and so on, until a clicking sound is detected and recorded as the first exhaust temperature.

[0053] In one embodiment, if Figure 3 As shown, step S102 includes:

[0054] S301, controlling the air conditioner to operate at a preset low frequency;

[0055] S302, detect whether there is a click sound, if so, go to step S303, if not, jump to step S304;

[0056] S303, recording the current operation time of the air conditioner when the clicking sound occurs as the first operation time;

[0057] S304, lowering the preset low frequency by a preset frequency step, and continuing to detect whether the clicking sound occurs. If it occurs, record the air conditioner operation time when the clicking sound occurs as the first operation time. If it does not occur, lower the preset frequency step again until the clicking sound is detected.

[0058] In this embodiment, the preset low-frequency is the lowest frequency set for the air conditioner to operate (which varies according to different outdoor ambient temperatures), which is generally above 14 Hz. The exhaust temperature at the preset low-frequency is generally greater than or equal to 20°C and less than the first exhaust temperature. The air conditioner is controlled to operate at the preset low-frequency and the operating time when the clicking sound occurs is detected (the operating time calculated from the time the air conditioner is turned on), and recorded as the first operating time.

[0059] Furthermore, if the air conditioner runs for a certain period of time at a preset low-frequency and no clicking sound occurs, the preset low-frequency frequency is reduced by a preset frequency step (preferably 1 Hz), that is, it continues to run at 13 Hz and detects the first running time when the clicking sound occurs. If the clicking sound still does not occur after a certain period of time, the preset frequency step is reduced again until the first running time is recorded after the clicking sound is detected.

[0060] In one embodiment, if Figure 4 As shown, step S103 includes:

[0061] S401, after recording the first operation time, controlling the air conditioner to increase the frequency from the current low frequency to the preset medium frequency, and detecting the change of the indoor ambient temperature;

[0062] S402, when the indoor ambient temperature changes to a preset temperature step, controlling the air conditioner to reduce the frequency from the preset intermediate frequency to the low frequency before the frequency increase;

[0063] S403, detecting whether the occurrence of a clicking sound and the current exhaust temperature being greater than or equal to the first exhaust temperature are simultaneously satisfied after the frequency reduction, if both are satisfied, proceeding to step S404, if not, jumping to step S405;

[0064] S404, calculating the time difference between the current operation time of the air conditioner after frequency reduction and the first operation time and recording it as the second operation time, and recording the intermediate frequency at this time;

[0065] S405. Increase the preset intermediate frequency by a preset frequency step as the new intermediate frequency, and re-obtain the exhaust temperature of the air conditioner during the switching operation of the low-frequency mode and the medium-frequency mode until the clicking sound occurs and the current exhaust temperature is greater than or equal to the first exhaust temperature, and record the second operating time and the corresponding intermediate frequency, as well as the intermediate frequency at this time.

[0066] In this embodiment, after recording the first operating time, the air conditioner is controlled to increase the frequency from the current low frequency to the preset intermediate frequency. The preset intermediate frequency is generally below 30 Hz and can meet the frequency of the compressor oil return. The compressor oil return can reduce the movement friction in the compressor, which is beneficial to reduce energy consumption and play a certain role in noise reduction. At the same time, the change of indoor ambient temperature is detected. The change of indoor ambient temperature will greatly affect the user comfort. Therefore, when the indoor ambient temperature changes to a preset temperature step (that is, it is reduced by 1°C, which has the advantage of taking into account the indoor environmental comfort), the air conditioner is controlled to reduce the frequency from the preset intermediate frequency to the low frequency before the frequency increase, and it is determined whether the air conditioner simultaneously meets the occurrence of the clicking sound and the current exhaust temperature is greater than or equal to the first exhaust temperature, and thus enters the operation of step S404 or S405 to obtain the second operating time.

[0067] It can be understood that the above process of obtaining the first operating time and the second operating time under multiple outdoor ambient temperatures simulates different working conditions when the air conditioner is used subsequently, and provides intelligent parameterized control for the subsequent use of the air conditioner to prevent clicking noise, thereby achieving the effect of preventing the occurrence of low-frequency clicking noise.

[0068] In one embodiment, if Figure 5 As shown, step S104 includes:

[0069] S501, when the air conditioner is enabled, obtaining the current outdoor ambient temperature;

[0070] S502, entering a corresponding anti-clicking program according to the current outdoor ambient temperature, and calling a first running time and a second running time in the corresponding anti-clicking program;

[0071] S503, repeatedly controlling the air conditioner to first run for a corresponding first running time and then increase the frequency to a medium frequency mode, and then run for a second running time and then decrease the frequency to a low frequency mode.

[0072] In this embodiment, after the anti-clicking program parameters under the aforementioned preset outdoor ambient temperature conditions are stored, the whole machine operates in the following manner during user use: when the air conditioner is enabled, the outdoor ambient temperature is detected and matched to enter the corresponding anti-clicking program, the whole machine runs the corresponding first operating time and then up-converts to the corresponding intermediate frequency, and then runs the second operating time and then down-converts to the original low frequency; this is repeated to achieve intelligent parameterized control to prevent the occurrence of low-frequency clicking sounds.

[0073] The embodiment of the present invention further provides an air conditioner control device, which is used to execute any embodiment of the above-mentioned air conditioner control method. Figure 6 , Figure 6 is a schematic block diagram of an air conditioner control device provided by an embodiment of the present invention.

[0074] like Figure 6 As shown, the air conditioner control device 600 includes: a self-check module 601, a parameter storage unit 602 and an anti-clicking operation module 603, and the self-check module 601 includes an exhaust temperature unit 6011, a first operating time acquisition unit 6012 and a second operating time acquisition unit 6013.

[0077] The first operation duration acquisition unit 6012 is used to acquire the current operation duration when the air conditioner produces a clicking sound during operation in the low-frequency mode, and record it as the first operation duration;

[0078] The second operation time acquisition unit 6013 acquires the current operation time when the exhaust temperature is greater than or equal to the first exhaust temperature during the switching operation of the air conditioner in the low frequency mode and the medium frequency mode, calculates the time difference between the current operation time and the first operation time and records it as the second operation time;

[0079] The parameter storage unit 6014 stores the operation parameters of the tapping sound self-checking process at each outdoor ambient temperature as a corresponding anti-tapping sound program;

[0080] The anti-clicking operation module 602 is used to obtain the current outdoor ambient temperature and enter the corresponding anti-clicking program when the air conditioner is enabled, and call the operating parameters in the corresponding anti-clicking program to control the air conditioner to achieve anti-clicking operation.

[0081] In the device, by controlling the air conditioner to perform the anti-clicking self-check process at multiple outdoor ambient temperatures, different anti-clicking operation parameters at different outdoor ambient temperatures are obtained, thereby constructing an anti-clicking program corresponding to each outdoor ambient temperature, so as to realize intelligent parameterized control to prevent the occurrence of low-frequency clicks when using the air conditioner. The needs of different low-frequency bands at different outdoor ambient temperatures can be met.

[0085] The first recording unit is also used to reduce the preset low-frequency frequency by a preset frequency step if the clicking sound does not appear, and continue to detect whether the clicking sound appears. If it appears, the air conditioner operating time when the clicking sound appears is recorded as the first operating time. If it does not appear, the frequency is reduced by a preset frequency step again until the clicking sound is detected.

[0086] In one embodiment, the second running time acquisition unit 6013 includes:

[0087] a temperature detection unit, for controlling the air conditioner to increase the frequency from the current low frequency to a preset medium frequency after recording the first operation time, and detecting a change in the indoor ambient temperature;

[0089] A second recording unit is used to calculate the time difference between the current operation time of the air conditioner after frequency reduction and the first operation time if both conditions are met and record it as the second operation time, and record the intermediate frequency at this time;

[0090] The second recording unit is also used to increase the preset intermediate frequency by a preset frequency step as a new intermediate frequency if the conditions are not met at the same time, and to re-acquire the exhaust temperature of the air conditioner during the switching operation of the low-frequency mode and the intermediate frequency mode until the conditions of the occurrence of a clicking sound and the current exhaust temperature being greater than or equal to the first exhaust temperature are met at the same time, and to record the second operation time and the intermediate frequency at this time.
