Embodiment 1

[0026] A method for air-conditioning noise control, such as figure 1 shown, including the following steps:

[0027] S1: Before turning on the air conditioner and adjusting the indoor fan of the air conditioner, estimate the variation of the speed of the indoor fan △R according to the current state and target state of the indoor fan of the air conditioner 内 =R 内目标 -R 内当前 ;

[0028] S2: △R 内 Range judgment: real-time judgment △R 内 If it belongs to a certain range from A1 to An, it is determined that the speed of the indoor fan is adjusted at a certain speed from V1 to Vn. Once the specific adjustment speed V is confirmed, go to step S3, if the adjustment speed of the indoor fan is not confirmed, continue to △R 内 Range judgment;

[0029] S3: Execute the fan adjustment of V rate: adjust the speed of the indoor fan according to the determined indoor fan adjustment speed V, and complete the indoor fan speed variation △R 内 The adjustment process, so that the air conditioner r...

Embodiment 2

[0032] A method for air-conditioning noise control, such as figure 2 shown, including the following steps:

[0033] S1: Before turning on the air conditioner and adjusting the outdoor fan of the air conditioner, estimate the variation of the speed of the outdoor fan △R according to the current state and target state of the outdoor fan of the air conditioner 外 =R 外目标 -R 外当前 ;

[0034] S2: △R 外 Range judgment: real-time judgment △R 外 If it belongs to a range from B1 to Bn, it is determined that the speed of the outdoor fan is adjusted at a rate from W1 to Wn. Once the specific adjustment speed W is confirmed, execute step S3, if the adjustment speed of the outdoor fan is not confirmed, proceed to △R 外 Range judgment;

[0035] S3: Execute fan adjustment at W rate: adjust the speed of the outdoor fan according to the judged adjustment speed W of the outdoor fan, and complete the variation of the speed of the outdoor fan △R 外 The adjustment process, so that the air conditi...

Embodiment 3

[0038] A method for air-conditioning noise control, such as image 3 shown, including the following steps:

[0039] S1: Turn on the air conditioner and before adjusting the air conditioner compressor, estimate the compressor speed variation △F=F according to the current state and target state of the air conditioner compressor 目标 -F 当前 ;

[0040] S2: Judgment of ΔF range: judge in real time that ΔF belongs to a certain range from C1 to Cn, and determine that the compressor adjusts the speed of the compressor at a certain rate from Y1 to Yn. Once the specific adjustment speed Y is confirmed, step S3 is executed, and if the adjustment speed of the compressor is not confirmed, the ΔF range judgment is continued;

[0041] S3: Execute compressor adjustment at Y rate: adjust the compressor speed according to the judged compressor adjustment speed Y, complete the adjustment process of compressor speed change △F, make the air conditioner reach a new stable operating state, and retur...

Abstract

The invention relates to the field of air conditioners, and discloses an air conditioner noise control method for improving the noise problem in an unsteady transition state. Before adjusting the air conditioner, the present invention first calculates the change in speed of the air conditioner according to the current state and target state of the air conditioner, and the change in speed includes the change in speed of the indoor fan △R 内 And / or the variation of outdoor fan speed △R 外 And / or compressor rotation speed variation △F; and then select the corresponding adjustment rate according to the rotation speed variation of the air conditioner to adjust the rotation speed of the corresponding components, so that the air conditioner reaches a new stable operating state. The invention is suitable for air conditioning adjustment, can effectively improve the noise problem in the transition state of the air conditioning adjustment process, and improve the noise comfort of air conditioning products.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner noise control method. Background technique [0002] When the user uses the room air conditioner for cooling or heating, the indoor fan speed increases or decreases due to the automatic adjustment of the air conditioner or the user changes the setting parameters such as temperature and wind speed, which will cause changes in the noise of the indoor air conditioner. At the same time, due to the change of wind speed of the indoor unit of the air conditioner, the pressure change of the refrigerant inside the refrigeration pipeline system is directly affected, thereby causing the noise of the outdoor unit of the air conditioner to change. This type of noise change has a great impact on the user's comfort, mainly in the decibel value of the noise change, the speed of the noise decibel value change, whether there is abnormal transmission sound, and whether there is abn...
