Mute mode control method and mute control system

Abstract

The invention provides a mute mode control method and a mute control system. The mute mode control method comprises the following steps of acquiring environmental reference noise and environmental noise, and controlling a compressor and / or controlling an outdoor fan and / or controlling an electronic expansion valve according to the environmental reference noise and the environmental noise. When a user falls asleep at night, noise generated by an air conditioner is more obvious, the noise mainly comes from vibration of the compressor, mechanical vibration caused by high-speed rotation of the outdoor fan and vibration generated during flowing of fluid in the electronic expansion valve, all forming main sources of the noise. In order to solve the problems of noise, according to the mute mode control method and the mute control system, three types of parameters including compressor frequency, outdoor fan rotating speed and the opening degree of the electronic expansion valve are adjusted according to a difference value between the environmental reference noise and the environment noise in actual work, and when the whole difference value is larger than a preset range, it is considered that the noise exceeds the standard so that adjustment can be started step by step; and adjustment cannot stopped until the whole difference value reaches the preset range.

Description

technical field [0001] The invention relates to the field of air conditioning control, in particular to a silent mode control method and a silent control system. Background technique [0002] When the user falls asleep at night, the air conditioner needs to be turned on to control the indoor temperature, but the air conditioner will generate noise during operation, which will seriously affect the user's sleep quality. Under the current technical conditions, it is difficult to avoid the existence of air conditioner noise. [0003] With the development of science and technology and the improvement of living standards, air conditioners are used more and more widely, and people have higher and higher requirements for air conditioner noise comfort. When the air conditioner is running, the noise caused by the high-speed rotation of the fan and the vibration of the external unit is inevitable, which affects the user's requirements for comfort.

AI Technical Summary

Problems solved by technology

[0005] When the user falls asleep at night, the noise generated by the air conditioner will be more obvious. The main source of the noise is the vibration of the compressor, the mechanical vibration caused by the high-speed rotation of the outdoor fan, and the vibration generated when the fluid in the electronic expansion valve flows. It is the main source of noise. In order to solve the problem of noise, in this application, the frequency of the compressor, the speed of the outdoor fan and the opening of the electronic expansion valve are adjusted. The adjustment is based on the benchmark noise of the environment and the actual working time When the overall difference is greater than the preset range, it is considered that the noise exceeds the standard and the adjustment is started gradually; until the entire difference reaches the preset range, the adjustment is stopped
