Air conditioning has become an indispensable necessity in people's life. With the popularization of air conditioning has expanded the scope of use, air-conditioning capacitance, all kinds of air conditioning failure are also increasing. Today share with you is a part of the air conditioning, the role of capacitors. I hope to give you some help.
Introduction to the role of air conditioning capacitor is the key component to start the air conditioning motor. Most of the air conditioning in the market is now using the capacitor to start the air conditioning and the operation of one body. The damage of capacitance will lead to the compressor for starting current rising too fast automatic open protection mode stop or cannot start the compressor, so that the air conditioning can not run normally or during the process of automatic power outage. In the process of launching the air-conditioner, the capacitor acts as a conductive role to help the compressor start normally.
Mixed capacitors on the market, all kinds of ill-made capacitors not only cannot guarantee the normal use. And in the process of use will lead to excessive current too small to cause damage to the air conditioning cannot be restored. Here to give you how to identify the quality of air-conditioner capacitors. You can test the capacity by using a multimeter to see if the value is too large or too small, and you can also use the multimeter two-stage tube file to test whether the capacitor is on directly, if the direct conduction proves that the capacitor is broken. The capacitance of AC and DC circuits is much lower in general. The working principle of Air-Conditioning Capacitor introduces Air-Conditioning is mostly single-phase compressor in the starting process it needs capacitor phase separation to start the capacitor is easy to overload at a higher voltage of 220V at home. The capacitor is directly related to whether the compressor can start normally, so when the air conditioning cannot start normally, the capacitor should be checked first, and the damage of capacitor is more.
So ,what's the principle of capacitors? The capacitive induction motor has two windings, starting winding and running winding. A large capacitor is connected in series with the starting winding. When the running winding and the starting winding pass through the single-phase alternating current, the starting winding current is 90 degrees earlier than the running winding in time due to the action of the capacitor. The induction current generated by the motor and the interaction between the current and the rotating magnetic field makes the motor to rotate. This is the principle of the capacitor.
