As shown in Figure 1, Figure 1 is a schematic diagram of an air conditioner with a built-in throttling device provided by an embodiment of the present application. Unit 1 and Outdoor Unit 2. The indoor unit 1 is arranged indoors, and is provided with an indoor heat exchanger 11 and a throttling device 12 . The outdoor unit 2 is arranged outdoors, and is provided with a four-way reversing valve 22 , an outdoor heat exchanger 21 and a compressor 23 .

The four-way reversing valve 22 has a first state and a second state.

In the first state, the compressor 23 is connected end to end with the indoor heat exchanger 11 , the throttling device 12 , and the outdoor heat exchanger 21 sequentially through the four-way reversing valve 22 .

In the first state, the air conditioner is heating, and the compressor 23 compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, and the high-temperature and high-pressure refrigerant releases heat and liquefies in the indoor heat exchanger 11 to become a low-temperature and high-pressure refrigerant The low-temperature and high-pressure refrigerant liquid is reduced by the throttling device 12 to become a low-temperature and low-pressure refrigerant liquid, and the low-temperature and low-pressure refrigerant liquid passes through the outdoor heat exchanger 21 to absorb heat and vaporize to become refrigerant gas and then enters the compressor 23 again .

In the second state, the compressor 23 is connected end to end with the outdoor heat exchanger 21 , the throttling device 12 and the indoor heat exchanger 11 sequentially through the four-way reversing valve 22 .

In the second state, the air conditioner is cooling, and the compressor 23 compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant. The high-pressure refrigerant liquid is reduced by the throttling device 12 to become a low-temperature and low-pressure refrigerant liquid, and the low-temperature and low-pressure refrigerant liquid passes through the indoor heat exchanger 11 to absorb heat and vaporize to become refrigerant gas and then enters the compressor 23 again.

During the heating and cooling process, the throttling device 12 will conduct a certain amount of heat transfer indoors, and will not be affected by abnormal outdoor temperature, so a certain working efficiency can be improved. However, the built-in throttling device 12 will cause relatively large indoor noise, which will affect user experience.

In order to solve the above problems, the present application provides a control method for air-conditioning noise, as shown in Figure 2, the control method includes the following steps:

Step S110: Obtain the indoor temperature and the set temperature.

After the air conditioner is powered on, it can send a connection request through an electronic device, such as an electronic bracelet, electronic watch or electronic mobile phone. The air conditioner responds to the connection request of the electronic device and establishes a communication connection with it.

After the connection is established, the user can set the temperature of the air conditioner through the electronic device, and obtain the indoor temperature through the sensor on the air conditioner.

Step S120: Based on the indoor temperature, determine the cooling capacity required to reach the set temperature.

After determining the indoor temperature and the set temperature, the air conditioner determines the cooling capacity required to reach the set temperature based on the indoor temperature.

Specifically, based on the indoor temperature and the set temperature, the temperature difference between the indoor temperature and the set temperature is determined, and the temperature difference ΔT=︱indoor temperature−outdoor temperature︱. Then obtain the air mass M in the corresponding space. Finally, based on the temperature difference ΔT and the air mass M, the cooling capacity Q required to reach the set temperature is determined. Q=C×M×△T to determine. Among them, Q is the cooling capacity or heat required, C is the air specific heat capacity, M is the air mass, and △T is the temperature difference.

Step S130: Based on the cooling capacity, determine the required operating frequency of the compressor and the corresponding operating noise of the throttling device.

After the cooling capacity Q is determined, based on the cooling capacity Q, the required operating frequency of the compressor and the corresponding operating noise of the throttling device are determined.

Specifically, based on the cooling capacity Q, determine the air supply temperature required to reach the cooling capacity Q within a preset time, for example, the preset time is 5-10 minutes, and when the air-conditioning wind speed is kept constant, it is determined within 5-10 minutes The supply air temperature required to achieve the cooling capacity Q.

After the required air supply temperature is obtained, the relationship between the air supply temperature and the preset temperature range is judged, and the preset temperature range is the air supply temperature range that the air conditioner can achieve in normal operation.

If the air supply temperature is within the preset temperature range, that is, when the air conditioner can reach the required air supply temperature, the air conditioner will determine the operating frequency of the compressor corresponding to the air supply temperature based on the air supply temperature, and throttle The corresponding operating noise of the device.

If the supply air temperature is outside the preset temperature range, that is, when the air conditioner cannot reach the required supply air temperature, then based on the boundary temperature of the preset temperature range, determine the operating frequency required for the compressor to reach the boundary temperature, and Operating noise corresponding to the throttling device.

For example, when the preset temperature range of the air conditioner is 16-30°C.

If the required air supply temperature is 20°C and the air conditioner can reach the required air supply temperature, then the operating frequency of the compressor at the supply air temperature of 20°C is obtained, and the corresponding operating noise of the throttling device is obtained at 20°C.

If the required air supply temperature is 10°C and the air conditioner cannot reach the required air supply temperature, then the operating frequency of the compressor when the air supply temperature is 16°C is obtained, and the corresponding operating noise of the throttling device is obtained at 16°C.

If the required air supply temperature is 31°C and the air conditioner cannot reach the required air supply temperature, then the operating frequency of the compressor at the supply air temperature of 30°C is obtained, and the corresponding operating noise of the throttling device is obtained at 30°C.

Step S140: Control the operation of the compressor according to the preset noise range of the working noise.

After obtaining the working noise corresponding to the throttling device, the operation of the compressor is controlled according to the preset noise range of the working noise.

Specifically, after acquiring the operating noise of the throttling device, the relationship between the operating noise of the throttling device and a preset noise range is determined.

If the working noise of the throttling device is within the preset noise range, the compressor is controlled based on the working frequency corresponding to the working noise of the throttling device.

If the operating noise of the throttling device is outside the preset noise range, the compressor is controlled based on the boundary frequency corresponding to the preset noise range.

For example, when the preset noise range is below 50 decibels, if the operating noise of the throttling device is 40 decibels, and it is determined that the operating noise is below 50 decibels, the compressor is controlled to work at an operating frequency corresponding to 40 decibels.

If the working noise of the throttling device is 60 decibels, if the working noise is determined to be above 50 decibels, then the compressor will be controlled at the corresponding working frequency of 50 decibels, and on the basis of ensuring the normal operation of the air conditioner as much as possible, avoid the throttling device from being generated indoors. Excessive noise.

The air conditioner noise control method provided by this application is used to control the air conditioner with a built-in throttling device. First, the indoor temperature is used to determine the cooling capacity required to reach the set temperature, and then the operating frequency and throttling required by the compressor are determined based on the cooling capacity. The working noise corresponding to the device, and finally, according to the preset noise range of the working noise, the operation of the compressor is controlled. On the basis of ensuring the normal operation of the air conditioner as much as possible, the throttling device can avoid excessive noise in the room and improve the user experience .

Based on the above-mentioned embodiment, as shown in FIG. 3 , before step S110: acquiring the indoor temperature and the set temperature, it also includes:

Step S101: Obtain the operating frequency of the compressor and the operating noise of the corresponding throttling device.

For the convenience of control, before the air conditioner works, the working frequency of the compressor and the working noise of the corresponding throttling device are acquired.

For example, if the operating frequency of the compressor is 30 Hz-130 Hz, the operating noise corresponding to the throttling device when the compressor is operating at 30 Hz-130 Hz is obtained.

Step S102: establishing a corresponding relationship between the operating frequency of the compressor within the preset noise range and the operating noise of the throttling device.

After obtaining the operating frequency of the compressor and the operating noise corresponding to the throttling device, a corresponding relationship between the operating frequency of the compressor and the operating noise of the throttling device within a preset noise range is established.

Specifically, for example, when the preset noise range is below 50 decibels, and the noise corresponding to the throttling device is 20 decibels to 60 decibels when the compressor is operating at 30 Hz-130 Hz, it only needs to be established under the condition of 20 decibels-50 decibels , the corresponding relationship between the operating frequency of the compressor and the operating noise of the throttling device.
