Air conditioner low-frequency resonance noise recognition control method and air conditioner

Abstract

The invention relates to the technical field of air conditioners, and specifically relates to an air conditioner low-frequency resonance noise recognition control method and an air conditioner. The method comprises the following steps: a noise sensor and a vibration sensor are used to collect data of the air conditioner; low-frequency resonance noise is identified and judged by giving noise and vibration thresholds; compressor frequency is adjusted for an abnormal noise frequency point to optimize the resonance noise; if resonance noise cannot be solved after the frequency of the compressor isadjusted for many times, an alarm system carries out data extraction and analysis on the abnormal noise frequency point, and the analysis data is fed back to a control terminal for processing at twoalarm levels of high-level alarm and low-level alarm; and therefore, an engineer can be helped to quickly find out the causes of problems and give accurate rectification schemes, the low-frequency resonance noise is optimized, the sound quality of the air conditioner is improved, the discomfort of a human body caused by the low-frequency noise is avoided, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for identifying and controlling low-frequency resonance noise of an air conditioner and an air conditioner. Background technique [0002] Air conditioning is the air conditioner (Air Conditioner). Refers to the equipment that uses manual means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. It generally includes cold source / heat source equipment, cold and hot medium transmission and distribution system, terminal devices and other auxiliary equipment. It mainly includes refrigeration host, water pump, fan and pipeline system. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically deal with the air state, so that the air parameters of the target environment meet the requirements. [0003] The outdoor unit of the air condi...

AI Technical Summary

Problems solved by technology

[0003] The outdoor unit of the air conditioner often produces low-frequency resonance noise during operation. The main noise source of the outdoor unit is the compressor and the fan system. Generally, the fan system produces less low-frequency resonance noise. The reason for the resonance noise of the compressor is that the compressor vibrates through the tube. The low-frequency resonance noise caused by the transmission amplification of the road, shell and chassis, and the other is that the vibration of the compressor directly radiates through the shell panel to generate low-frequency resonance noise. In terms of the sound quality of noise, the sound shows a dull "hum" sound, which spreads far away, is irritating to the human body's sense of hearing, and is extremely uncomfortable to hear, which has seriously affected people's living environment
