What Are the Main Types of AC Compressors?

Your home air conditioning (AC) is essential for having a comfortable environment. And the AC compressor is vital to the smooth operation of your home air conditioning system.

If your AC compressor stops, your AC cannot work properly. This would make your home hot and uncomfortable. So you need to know the different types of compressors before you install a new HVAC technology or find a replacement if necessary.

Fortunately, we’re here to help. Here is a quick guide to the different types of AC compressors:

Reciprocating

This compressor operates through the reciprocating motion of one or more pistons within its cylinder. It compresses the air to create a required pressure level. 

Reciprocating can be used in a wide variety of commercial and residential applications. It can function in split-system and packaged air conditioners, window units, freezers, and heat pumps. They are also extremely efficient, boasting up to 90% energy efficiency during some applications.

The main benefit of using this compressor is its ability to provide a steady performance even when operating at high speeds. However, they can also be somewhat noisy when compared to other types of compressors.

Rotary

Rotary-type AC compressors are one of the most common compressors on the market today. This type of compressor is to convert liquid refrigerant into high-pressure vapor by using a set of revolving rotors. It is also self-lubricating, making it ideal for use in air-conditioning units as well as in refrigeration systems.

The main advantages of these compressors are their long working life, low power consumption, and silent operation. Another major advantage of these compressors is that they are small in size, which makes them ideal for use in tight spaces.

Their high efficiency and low sound production also make them a preferred choice for many applications. And unlike other compressors, rotary compressors can handle higher pressure with the same amount of power.

Scroll

A scroll compressor uses two intertwining scrolls, one orbiting inside of the other. It draws in refrigerant, compresses it, and pushes it into the condenser coils. It needs fewer components than traditional compressors, which tend to be lighter, quieter, and more reliable.

Scroll compressors have a lower start-up torque. This makes them less likely to draw too much power from the system, reducing utility bills. The scroll compressor is also self-lubricating, so you don’t have to worry about adding oil to it yourself.

The only real disadvantage of this compressor is it has a relatively complex design. So it can be more expensive than other types of compressors. You should consider this factor when deciding on a new air conditioning installation.

Learning to Differentiate the Many Types of AC Compressors

AC compressors are a key component in the cooling process of any traditional AC setup. The main types of AC compressors are rotary, scroll, and reciprocating. Each of these compressors has its advantages and disadvantages.

So if you’re seeking to replace your existing compressor or are due for a new install, be sure to do your research. You can also contact an experienced HVAC technician. They can help discuss your options and provide a professional installation.
