FAQs

Q.

What is the difference between a Rotary Compressor and a Scroll Compressor?

A.

In a Rotary Compressor compresses refrigerant inside its compression chamber with the help of the rotary motion of the roller and vertical movement of the vane. In contrast to this, a Scroll Compressor, compression of the refrigerant takes place inside the scroll wrap with the help of scrolls.

Q.

What is a Rotary Compressor?

A.

A Rotary compressor uses a rotary-type positive-displacement mechanism for compressing the refrigerant. A Rotary Compressor is composed of a body and an accumulator. The body can be split into two parts: one with the motor and the other with the compressor.

Q.

Which systems use Rotary Compressors?

A.

All these components are essential to the operation of an air conditioner. Air conditioners, just like refrigerators, require a compressor to function. The most common compressor used in residential air conditioners is a Rotary Compressor.

Q.

Why do Rotary Compressors have accumulators?

A.

The refrigerant from the evaporator is not directly sucked into the compression chamber of the compressor; instead, it passes through the accumulator first. The accumulator helps the liquid refrigerant evaporate before being sucked into the compression chamber.

Q.

What is the difference between a Single Rotary and a Twin Rotary Compressor?

A.

A Single Rotary Compressor has one cylinder, while a Twin Rotary Compressor has two cylinders, offering greater efficiency and balance.
