I. What is a capacitor?
A capacitor is an essential component of an air conditioning unit, which plays a crucial role in its functioning. It is a small, cylindrical-shaped electrical device that stores and releases electrical energy. The capacitor is responsible for providing the initial jolt of electricity to start the motor of the AC unit, and then it continues to provide a constant flow of electricity to keep the motor running smoothly.
Types of capacitors
There are two main types of capacitors used in AC units: start capacitors and run capacitors. Start capacitors are used for starting the motor, and they provide a large amount of electricity for a short period of time. Once the motor is started, the run capacitor takes over and provides a steady flow of electricity to keep the motor running. Run capacitors are also responsible for maintaining the efficiency of the motor by creating a phase shift between the voltage and the current.
Start capacitors are usually larger in size compared to run capacitors and have a higher capacitance rating. They are also known as electrolytic capacitors as they use an electrolyte solution to increase their capacitance. Run capacitors, on the other hand, are smaller in size and have a lower capacitance rating. They are also known as non-electrolytic capacitors as they do not use an electrolyte solution.
Another type of capacitor used in AC units is the dual run capacitor. As the name suggests, it combines the functions of both start and run capacitors and is used in units where both types of capacitors are required. This helps in reducing the number of components and simplifies the design of the unit.
