Problems solved by technology
[0005] The present invention provides a control method and device for vibrating the compressor and fan of an inverter air conditioner, which is used to solve the problem of vibrating in the prior art, which is contrary to the actual operation process of the air conditioner, which will lead to the outdoor vibration of the air conditioner. The heat exchange efficiency of the air conditioner is low; moreover, the operating frequency of the compressor cannot be finely targeted, and the heat exchange function of the outdoor unit of the air conditioner cannot be effectively used, which will also lead to low heat exchange efficiency of the outdoor unit of the air conditioner question

The invention provides a control method and a control device for beat vibration of a compressor and a fan of a variable frequency air conditioner. The method comprises the following steps: aiming at different operating frequency intervals of the compressor, determining the fan blade passing frequencies of fan blades in different operating frequency intervals of the compressor, wherein the fan blade passing frequencies are difference values between the operating frequencies of the compressor and a predetermined frequency difference value, and the number of the operating frequency intervals of the compressor is at least three; and according to the fan blade passing frequencies, determining the fan rotating speeds of the fan in the different operating frequency intervals of the compressor. The double frequency of the fan blade passing frequency of an outdoor unit of the air conditioner is relatively higher than the operating frequency of the compressor, so that a beat vibration phenomenon is avoided; different fan rotating speeds are provided elaborately for the operating frequencies of the compressor, so that the heat exchange function of the outdoor unit of the air conditioner is effectively utilized; the fan rotating speed is in direct proportion to the operating frequency of the compressor and is as same as the actual operating process of the air conditioner, so that the heat exchange efficiency of the outdoor unit of the air conditioner is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and device for vibrating a frequency conversion air conditioner compressor and a fan. Background technique [0002] Air conditioners have been widely used in people's lives. Due to the advantages of stable operation, non-stop operation, automatic adjustment of compressor frequency with changes in indoor and outdoor temperatures, energy saving and environmental protection, frequency conversion air conditioners have become the current development trend of air conditioners. . The operating frequency range of the compressor of the inverter air conditioner is relatively large. If the operating frequency of the compressor is close to or consistent with the double frequency of the passing frequency of the fan blades, the sound of the two similar frequencies will be superimposed, which will cause the outdoor air conditioner to The sound of the machine will be l...
