Air Conditioner Capacitor

How do the air conditioner capacitor work?

Air conditioner capacitor is a capacitor used for both the compressor and the fan in an air conditioning system. For smaller systems, these motors are both single phase. For larger systems, they may use a three phase compressor and a single phase fan, or even both a three phase compressor and fan.

usually we could buy single or dual type air conditioner capacitor.there have a special type combined air conditioner capacitor, Turbo®200 made from AmRad capacitor.( total of 67.5 microfarads (mfd), with taps at 2.5mfd, 5mfd, another 5mfd, 10mfd, 20mfd and 25mfd.)

A single unit run capacitor is used to continuously adjust current or phase shift to a motor’s windings in an effort to optimise the motor’s torque and efficiency performance. All run capacitors are designed for continuous duty, and as a result, have a much lower failure rate than start capacitors. A single unit air conditioner capacitor will have 2 connections and will be dedicated to optimising current on one motor.

Dual run air conditioning capacitors are 2 run capacitors in one case. They have nothing else that makes them electrically special. They generally have connections marked “C” for “common”, “H” or “Herm” for “Hermetic Compressor,” and “F” for “Fan.” They will also have 2 different capacitor ratings for the 2 different parts. You might see 40/5 MFD, meaning that one side is 40 microfarads (measurement of capacitance), and the other side is 5 microfarads. The smaller value will always be connected to the fan. The larger connection will always be connected to the compressor.

The dual run air conditioning capacitor design’s only advantage is that it comes in a small package with only 3 connections. There is no other difference. In a pinch and even as a permanent solution, if there is enough space for mounting, using two separate run capacitors in place of your original dual run motor capacitor is an acceptable practice.
