Types
In the realm of “Aircon Capacitor Wiring,” understanding the different types of capacitors is essential for selecting the most appropriate capacitor for a particular air conditioning system. The two main types of capacitors used in aircon capacitor wiring are capacitor-start and permanent split capacitor.
-
Capacitor-start
Capacitor-start capacitors are typically used in single-phase air conditioners. They provide an extra boost of power to start the compressor motor, and then they disconnect from the circuit once the motor is running. -
Permanent split capacitor
Permanent split capacitor motors are used in both single-phase and three-phase air conditioners. They have two capacitors, one for starting and one for running. The starting capacitor is typically larger than the running capacitor, and it is wired in parallel with the starting winding of the motor. The running capacitor is wired in series with the running winding of the motor.
The choice between a capacitor-start capacitor and a permanent split capacitor motor depends on several factors, including the size and type of air conditioner, the starting torque required, and the desired efficiency. Capacitor-start capacitors are less expensive than permanent split capacitor motors, but they are also less efficient. Permanent split capacitor motors are more efficient than capacitor-start capacitors, but they are also more expensive.
