Step 400, when executing the noise reduction operation, the user can directly quit the current and subsequent steps of the method by pressing the cooling and heating keys or the shutdown key, and the noise reduction request of the user is not processed in the set quit time period.
The set exiting time period is used for preventing the influence on the normal use of the air conditioner caused by the short interval time between the exiting and entering of the method.
As shown in fig. 1, an example of one operation step of the present control method in the air conditioner is given below.
Step A, a user sends a request for entering an autonomous noise control program to an air conditioner control module through a remote controller key or other man-machine interaction modes; a user presses a key once within 5 seconds, which represents that a first-level noise control program is entered; continuously pressing twice within 5 seconds to represent entering a secondary noise control program; three times or more within 5 seconds represents entering a three-level noise control program.
It should be noted that the noise control program is different according to the current operation mode of the air conditioner, for example, when the air conditioner is in the air supply mode, the operation of the first-stage noise control program is that the rotation speed of the indoor fan is reduced by one gear and the rest is controlled unchanged, the operation of the second-stage noise control program is that the rotation speed of the indoor fan is reduced by two gears and the rest is controlled unchanged, the operation of the third-stage noise control program is that the rotation speed of the indoor fan is reduced by three gears and the rest is controlled unchanged, when the air conditioner is in the cooling or heating mode, the operation of the first-stage noise control program is that the rotation speed of the indoor fan is reduced by one gear and the rest is controlled unchanged, the operation of the second-stage noise control program is that the rotation speed of the indoor fan1Is reduced to H2(here, H)2＝a*H1A is a constant, the value range of a is 0-100%, the constant can be set to different values according to needs, preferably 0-10%, for example, the value range is 3% -6%, the preferred value is 4%), the rest is controlled to be unchanged, the operation of the three-level noise control program is to reduce the rotating speed of the indoor fan to three levels, and the compressor is controlled to reduce the current frequency H from the current frequency H1Is reduced to H2(here, H)2＝b*H1B is a constant, the value range of b is 0-100%, the value range can be set to different values according to needs, preferably 0-25%, for example, the value range is 7-12%, the preferred value is 8%, and the rest is not controlledAnd (6) changing.
Through the degradation operation, the rotating speed of the fan is reduced and/or the frequency of the compressor is reduced, so that the heat exchange performance of the indoor unit is reduced, the circulation quantity of the refrigerant flowing through the indoor unit in unit time needs to be reduced for full evaporation or condensation, and the frequency of the compressor can be reduced.
And step B, the control module judges whether the oil return and defrosting mode is in, and if so, the request is rejected.
And C, if not, allowing the user to enter the autonomous noise control program, and setting the priority as the first position.
If a protection control condition is triggered during the operation of the above-described autonomous noise control routine, the priority of the control routine is changed to the second bit, and the priority of the protection control is changed to the first bit, i.e., the protection control routine is preferably executed.
D. The control module judges whether the current operation mode is air supply, refrigeration or heating.
For a heat pump type unit, whether a current air conditioner is in a cooling mode or a heating mode can be generally judged by detecting whether a four-way valve is powered on, and the current air conditioner is in a powered-off state and in a powered-on state in the heating mode according to the condition that the four-way valve is in the cooling mode.
Of course, it is not excluded that some unit four-way valves are controlled to be in a power-on state in the cooling mode and in a power-off state in the heating mode.
In a word, for a specific certain heat pump unit, the current air conditioner can be judged to be in a cooling mode or a heating mode by the fact that the four-way valve is in a power-off state or a power-on state.
E. And entering a noise autonomous control program.
F. The control program exits by pressing a cooling key, a heating key or a shutdown key in the running process, and the control can not be entered within 10 minutes.
A specific case (exemplified by a blowing mode) of an operation step in the air conditioner of the above-listed one control method is given below, and the following case is an explanation of the present invention and the present invention is not limited to the following case.
The actual measurement noise under the high wind operation is 54dB under the normal operation under certain 5P indoor unit air supply mode, and national standard specified value 55dB satisfies the national standard. But part of the user experience is difficult to feel noise, and the user is allowed to carry out autonomous noise control for improving the comfortable experience of the user.
The user sends the noise autonomous control request, and once the button is pressed within 5 seconds, the user enters a primary noise control program, and at the moment, the actually measured noise is reduced to 51dB, so that the user noise experience is good, but the user noise experience is still unsatisfied.
The user presses the key again, sends the noise and independently controls the request, presses the key 2 times in 5 seconds, represents and gets into second grade noise control procedure, and the actual measurement noise falls to 47dB this moment, and user noise experience becomes good, and the user is satisfied with.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
