Choose the Right Air Compressor to Make Your Home Cool and Refreshing

A compressor is the backbone of any air conditioner. The compressor draws in cool air from the refrigerant. If the compressor malfunctions then your air conditioner might not cool at all. Regular maintenance of your air conditioner can keep such issues at bay.

Different Types of Air Compressors

Compressors can be classified based on their functionality such as:

  • The stages of compression
  • Depending on the cooling method
  • The lubrication method
  • The drive method

The basic types of air compressors include:

  • Centrifugal
  • Rotary
  • Reciprocating
  • Scroll
  • Screw

When you go in for branded AC’s such as Voltas, you might find air conditioners which different kinds of compressors. When you purchase air conditioners, ensure that you compare prices and features. There are many websites such as that can help you in getting the right air conditioners based on your budget.

Overview of the Different Compressors

Centrifugal compressors are generally used in plants or refineries as they produce high pressure discharge. The energy is passed from a rotating impeller. The centrifugal compressors have only bearings and seals. They have no internal wearing parts and are highly reliable and efficient. Here, the air moves in a circular motion and the impeller spins at a great force to gain velocity.

Rotary and reciprocating air compressors are the commonly used compressors in a standard AC.  Rotary compressors can be divided into two parts. One that comes with vanes and blades that rotates with the shaft. The other, that comes only with the blade and remains stationary. Here the air gets trapped by the blades and compressed into gas. This is later discharged by the condenser through an exhaust port.

Reciprocating compressors consist of a piston and a crankshaft. When the piston moves upwards, the air gets compressed and pushed out into the condenser trhough the exhaust valve. The compressor comprises of many cylinders. The mostly commonly used ones are the two, four and eight cylinders.

Scroll compressors come with a fixed and rotating scroll. The fixed scroll remains stationary, while the rotating scrolls the air to the centre and dispels it through the condenser. The screw compressors make use of helical rotors to capture the air and move it from one end to the other. This then gets discharged from the condenser.

Rotary V/s Reciprocating Compressors

Many customers are often confused onto which air conditioners would best suit their homes. The debate of whether to go for rotary or reciprocating compressors is a never-ending battle. Voltas has a nice collection of both rotary as well as reciprocating compressors

  • Reciprocating compressors are easy to clean and maintain than rotary
  • Rotary are best suited offices or commercial spaces, whereas reciprocating is good for homes
  • Reciprocating compressors work well in high temperatures
  • Rotary compressors make less noise than its counterparts
  • Rotary compressors are more expensive than reciprocating compressors


If you are looking at air conditioners for your office space, then going in for rotary air compressor AC’s would be an ideal option for you. Ensure that you do your homework when it comes to choosing the right AC.
