Embodiment Construction
[0034] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.
[0035] refer to figure 1 , an air conditioner low-frequency resonance noise identification and control method provided by the present invention, the vibration sensor is arranged on the air conditioner pipeline and the casing and the noise sensor is arranged on the external unit for data collection, and the abnormal frequency point of the compressor with abnormal vibration is determined, and the abnormal frequency point is determined. Analyze the noise data at the frequency point to determine whether there is low-frequency noise at the abnormal frequency point. If there is low-frequency noise at the abnormal frequency point, adjust the frequency of the compressor at the abnormal frequency point at least once, and determine whether there is still noise at th...

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...
