Embodiment 1

[0044] This embodiment provides a noise control method for an air conditioner, which is applicable to a multi-connected air-conditioning system, and specifically controls and improves the standby noise of a multi-connected indoor unit. figure 2 It is a flow chart of the air conditioner noise control method provided in Embodiment 1 of the present invention, as figure 2 As shown, the method includes the following steps:

[0045] S201. During the operation of the multi-connected air-conditioning system, if it is detected that the current indoor unit is in a standby state, acquire the number of target objects in the area where the current indoor unit is located.

[0046] S202. If the number of target objects is not zero, acquire the current noise data of the liquid flow sound of the internal machine.

[0047] S203. Control the current opening of the electronic expansion valve of the internal unit according to the number of target objects and the noise data.

[0048] During the...

Embodiment 2

[0065] This embodiment provides a specific example to describe the above air-conditioning noise control method, but it should be noted that this specific example is only for better illustrating the present application, and does not constitute an improper limitation to the present application. Explanations of terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated in this embodiment.

[0066] refer to image 3 , Each indoor unit of the multi-split air-conditioning system is equipped with an infrared heat source sensor and a noise sensor. The infrared heat source sensor is used to detect the heat source, and specifically detect the target object in the area where the internal unit is located; the noise sensor is used to detect the noise data of the liquid flow sound of the internal machine. Use the data detected by the sensor to control the electronic expansion valve of the internal unit through a specific logic control idea.

Embodiment 3

[0074] Based on the same inventive concept, this embodiment provides an air conditioner noise control device, which can be used to implement the air conditioner noise control method described in the above embodiments. The device can be realized by software and / or hardware, and generally the device can be integrated into the controller of the air conditioner.

[0075] Figure 4 It is a structural block diagram of the air-conditioning noise control device provided in Embodiment 3 of the present invention, as Figure 4 As shown, the device includes:

[0076] The first acquiring module 41 is configured to acquire the number of target objects in the area where the current indoor unit is located if it is detected that the current indoor unit is in a standby state during the operation of the multi-connected air-conditioning system;

[0077] The second acquisition module 42 is used to acquire the noise data of the liquid flow sound of the current internal machine if the number of ta...

Abstract

The invention discloses a noise control method and device of an air conditioner and a VRF air conditioning system. The method comprises the steps that in the running process of the VRF air conditioning system, if it is detected that the current indoor unit is in a standby state, the number of target objects in the area where the current indoor unit is located is acquired; if the number of the target objects is not 0, the noise data of liquid flow sounds of the current indoor unit are acquired; and the opening degree of an electronic expansion valve of the current indoor unit is controlled according to the number of the target objects and the noise data. The number of the target objects in the area where the standby indoor unit is located and the noise data of the liquid flow sounds of thestandby indoor unit are combined to control the opening degree of the electronic expansion valve of the standby indoor unit so as to control the flow of a refrigerant in the standby indoor unit, and therefore abnormal noise generated by refrigerant flowing of the standby indoor unit in the VRF air conditioning system is effectively controlled and lowered, the noise quality under the product standby state is improved, and the evaluation of users to products can be improved to the largest extent.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner noise control method, device and multi-connected air conditioner system. Background technique [0002] When the multi-connected air-conditioning system is running in heating mode, the number of indoor air-conditioning units will be selected according to the user's needs, so there will be some indoor units that are not powered on. , usually in the state of not starting, the electronic expansion valve of the heating internal unit will reserve a certain opening degree (that is, the reference reserved opening degree) so that the refrigerant can participate in the circulation of the system, such as figure 1 shown. When the refrigerant is flowing, because the standby fan of the internal unit is not running, the sound of the refrigerant flowing will be amplified, forming an abnormal sound of air flow, which will affect people's normal life in severe ...
