Abstract

The invention discloses a method and a system for eliminating frequency resonance for a frequency conversion air conditioner. A velocity sensor and a vibration sensor are used for obtaining the vibration state of the air-conditioning system, and the vibration state of the air-conditioning system is adjusted, since the vibration is detected continuously, the whole air conditioner always works in a closed-loop system, and the air conditioner is always optimized intelligently; with the technology, development cycle of a cooling system and an electric control system is shortened, product development cycle is reduced, and development cost is saved.

Description

Technical field [0001] The invention relates to a method and system for eliminating frequency resonance of a frequency conversion air conditioner, in particular to a method and system for eliminating frequency resonance of a frequency conversion air conditioner according to a voltage signal collected by a vibration sensor. Background technique [0002] In the air-conditioning industry, there are vibrations and noises, whether it is variable frequency or fixed frequency. When the control is improper, the energy efficiency ratio is low. The service life of the machine may be reduced by more than half. At the same time, it is also a noise source, which directly affects our economy and daily life. life. There are two major systems in the air conditioner. One is a refrigeration system and the other is an electric control system. Because vibration problems are often blamed on each other, one is considered to be a motor drive problem, and the other is considered to be a refrigeration s...
