Problems solved by technology

When the indoor fan is running at a low wind speed and the compressor is in a high-frequency state, it is easy to cause the following problems: (1) the internal unit is prone to condensation; (2) the entire air conditioning system is prone to various protections such as pressure and current, causing the compressor to frequently Downtime, affecting the comfort of use
When the indoor fan is running at high wind speed and the compressor is at low frequency, it is easy to cause accidents such as compressor liquid shock
It can be seen that when the indoor fan and compressor are in an unreasonably matched operating state, it is easy to cause abnormal operation of the air conditioning system and related unnecessary protection.

Abstract

The invention provides a compressor frequency controlling method, a compressor frequency controlling device and an air conditioner. The compressor frequency controlling method comprises the following steps of detecting the revolving speed of an indoor fan of the air conditioner; and determining a running frequency range of a compressor according to the running revolving speed range of the revolving speed of the indoor fan. By the technical scheme, the running frequency range of an outdoor compressor is determined according to the different running revolving speed ranges of the revolving speed of the indoor fan, a circumstance that the outdoor compressor can run in various running frequencies when the indoor fan is in different running revolving speed ranges can be avoided, the running revolving speed range of the indoor fan is reasonably associated with the running frequency range of the outdoor compressor, and the purposes of effectively improving the running reliability and the using comfort level of the air conditioner and improving the user experience are achieved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a compressor frequency control method, a compressor frequency control device and an air conditioner. Background technique [0002] At present, in the conventional split-type inverter air conditioner, the indoor fan and the outdoor compressor are not linked with each other when the air conditioning system is running, that is, the speed of the indoor fan and the operating frequency of the outdoor compressor have not established a good correlation, which is likely to cause some unnecessary problems and affect the air conditioner. normal operation. The specific performance is: the speed of the indoor fan is divided into three levels: high, medium and low, and the frequency of the outdoor compressor is divided into 25 levels from F1 to F25. No matter what the speed of the indoor fan is, the frequency range of the outdoor compressor is all 25 levels. collection. When...
