Embodiment

[0055] see figure 1 , the embodiment of the present invention provides a compressor frequency control method and device, which are applied to the air conditioner 10. The compressor frequency control method and device provided in this embodiment can adopt different frequency limiting methods according to different running times, and can simultaneously Improve the problem of noise and heating demand, and improve the user experience.

[0056] In the heating mode, the heating capacity of the air conditioner 10 is generally measured when the speed of the internal fan is above the high gear, so in the heating mode, the indoor fan can basically guarantee the heating demand of the user. . The compressor will produce abnormal noise during the working process, and the noise will be transmitted to the room through the pipeline. If the wind speed of the internal fan is high, the noise of the compressor can be covered, and if the wind speed of the internal fan is low, the noise of the com...

Abstract

The invention provides a compressor frequency control method, device and air conditioner, and relates to the technical field of air conditioners. The compressor frequency control method includes: obtaining the running time of the compressor; judging whether the running time is greater than the preset time; if the running time is less than or equal to the preset time, controlling the air conditioner to enter the wind speed limit mode; if the running time is greater than the preset time, then Obtain the temperature value of the inner ring of the air conditioner; obtain the temperature value of the inner disk of the air conditioner; control the frequency of the compressor according to the temperature value of the inner ring and the temperature value of the inner disk. When the running time is less than the preset time, the frequency of the compressor is limited according to the wind speed frequency limiting mode. When the running time exceeds the preset time, the frequency of the compressor is adjusted through the temperature value of the inner disk and the temperature value of the inner ring, which can reduce noise and at the same time The heating capacity is maintained, thereby improving the user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a compressor frequency control method and device and an air conditioner. Background technique [0002] In the heating mode, the heating capacity of the air conditioner is generally measured when the speed of the internal fan is above the high wind speed. Therefore, in the heating mode, the internal fan is turned on to the high wind speed to basically guarantee the heating demand of the user. The compressor will produce abnormal noise during the working process, and the noise will be transmitted to the room through the pipeline. If the wind speed of the internal fan is high, the noise of the compressor can be covered, and if the wind speed of the internal fan is low, the noise of the compressor cannot be covered. . In general, considering the comfort of the user, the wind speed limit is mostly set in the middle and low wind speed and the silent wind speed, so as ...
