Types of AC Compressors and How They Work

The AC compressor is one of the most important parts of an AC that ensures the success of the cooling cycle—all thanks to the circulation of the unit’s refrigerant to the other parts. It is technically the heart of the entire system that promotes smooth running, which is why you should know the various types of AC compressors and their working principles.

Reciprocating Compressor

First on the list is the reciprocating AC compressor, which is one of the most common. It is easy to see why, considering that it is one of the first types invented. Luckily, there have been several design improvements over the years thanks to new technology. It works when the piston moves up and then down and compresses the air inside the cylinder. Its simple construction makes it easier to maintain, and the best part is that it has a lower initial cost.

Scroll Compressor

Unlike other types of air conditioner compressors, the scroll compressor is a relatively newer invention. It is also called the scroll vacuum pump and is known for its straightforward design with a fixed and orbiting scroll. It comes in handy when you need a compact component with very little noise. Apart from being very energy-efficient, this version is known to last longer because it doesn’t feature many moving parts.

Screw Compressor

What makes this type stand out is the fact that it is best for use in commercial settings, where the buildings are large and heavy AC usage is required. They are ideal for when there is a need for consistent cooling, which works because they can effectively handle massive volumes of air. It is also praised for its reliability, easy maintenance, and efficiency for large-scale performance, including industrial needs.

Rotary Compressor

A different type of AC compressor is the rotary, which is the go-to when loud noise is a huge deal. They stand out for being some of the quietest compressors that don’t suffer a lot from vibration. Inside, there is a bladed shaft that rotates in a marked cylinder, pushing and compressing the refrigerant.

Centrifugal Compressor

The centrifugal compressor is a one-of-a-kind version that is best for use in the largest HVAC systems. Just from its name, you can tell that it pulls in the refrigerant using centrifugal force. This compressor’s application explains why it is one of the biggest and priciest in the market.
