Capacitors are the key components for starting air-conditioning motors. Most air conditioners on the market today use capacitors to integrate air-conditioning and operation.What is the function and principle of air conditioner capacitors in air conditioner?The following is an introduction to the functions and principles of air conditioning capacitors.
- The role of air conditioning capacitors
Capacitors are the key components for starting air-conditioning motors. Most air conditioners on the market today use capacitors to integrate air-conditioning and operation. The damage of the capacitor will cause the compressor starting current to rise too fast. The automatic protection mode will be shut down or the compressor cannot be started, which will cause the air conditioner to fail to operate normally or automatically power off during startup. During the startup of the air conditioner, the capacitor plays a role of conduction to help the compressor start normally.
- Working principle of air conditioning capacitors
Air conditioners are mostly single-phase compressors that require capacitor split-phase to start during the start-up process. Capacitors running at a higher voltage of 220V at home are easily overloaded. The quality of the capacitor is directly related to whether the compressor can start normally. Therefore, when the air conditioner cannot start normally, the capacitor should be checked first, and the capacitor is often damaged.
So what is the principle of the capacitor? The capacitive induction motor has two windings, which are the starting winding and the running winding. Connect a large-capacity capacitor in series with the start winding. When the running winding and the starting winding pass single-phase alternating current, the starting winding current is ahead of the running winding by a 90-degree angle in time due to the capacitor. When the magnetic field rotates, the motor generates an induced current. The current and the rotating magnetic field The interaction causes the motor to rotate.
