What Types of Compressors Are and How They Work?
Compressors are the heart of a refrigeration system. It has different types, styles, forms, and characteristics.
Based on the internal mechanisms, there are different types of compressors having different unique capabilities, pros, and cons.
These two main generic principles are positive displacement and dynamic.
However, there are five main types of compressors used in refrigeration systems. They are :
- Reciprocating Compressor.
- Scroll Compressor.
- Screw Compressor.
- Rotary Compressor.
- Semi Hermetic Compressor.
- Centrifugal Compressor.
Type of Scroll Compressor in Refrigeration Systems and How it Works?
Scroll-type compressor refrigerant gas in an internal compressor way where the fluid flows into the fixed and movable scroll and becomes a high-pressure from normal pressure.
The discharge port in the middle of the scroll discharges the fluid.
The two types of scroll compressors are radially scrolled compressors and axially compliant scroll compressors.
The scroll compressor has fewer moving parts and minimum torque variation.
So it ensures a smooth and 10% to 15% more efficient result than other compressors.
It is widely used in residential central heat pumps, HVAC systems, and automotive AC systems.
Scroll Compressor Brands: Copeland Scroll Compressor, Danfoss Scroll Compressor, Hitachi Scroll Compressor, Panasonic Scroll Compressor, Daikin Scroll Compressor.
Type of Rotary Compressor in Refrigeration Systems and How it Works?
The rotary-type compressor has two rotors that run in rotary types in opposite directions in a positive displacement mechanism to compress the refrigerant.
The main two types are oil-injected and oil-free rotary screw compressors.
It used the “The Airend” way where the air is compressor from inside.
It is famous because of its durable, efficient, and simplest mechanism which ensures higher air quality.
So it is important to choose a good brand for the best Rotary compressor for refrigeration.
The best Rotary compressor comes with Hitachi, Highly, Horizontal, GMCC, Panasonic, LG, GREE, and other brands.
It is also widely used in a large volume of commercial, industrial, and construction HVAC applications and captures a large portion of the refrigeration compressor market.
Rotary Compressor Brands: Horizontal Rotary Compressor, Mini Rotary Compressor, Horizontal Condensing Unit.
Type of Semi-Hermetic Compressor in Refrigeration Systems and How it Works?
A semi-hermetic type compressor has a cast iron casing for its necessary parts, but the compressor and motor are together like a hermetic.
It raises the pressure of the refrigerant and flows it through the pipe.
The gas enters into low-pressure space through a suction valve which is used to control the pressure.
It is very accessible for repair and maintenance and has a longer lifetime.
Semi-hermetic Compressor Brand: Bitzer, Copeland, Frascold, Carrier, Miracle, or Piston types.
It is used in medium or high-temperature air conditioning units and refrigeration systems.
Semi-hermetic Compressor for condensing unit: Bitzer Condensing Unit, Air Cooled Condensing Unit, Semi-Hermetic Condensing Unit.
Types of Screw Compressors in Refrigeration Systems and How it Works?
A screw types compressor uses two male and female screws or rotors for compressing the gas.
Both males and female screws rotate, gas flows into them and changes the pressure of gas and discharge at the end of the screws.
These screw types of compressors are usually very energy efficient and consume very little amounts of oil.
There are Bitzer screw compressors, Frascold screw compressors, Miracle screw compressors, and Carrier screw compressors available to us.
A screw compressor is used in larger commercial and industrial applications if large volumes of high pressure are required. It is also used to replace piston compressors.

Types of Reciprocating Compressors in Refrigeration Systems
The compressor used in the refrigerator, freezer, and pump system is a refrigerator compressor.
It can be a single-phase motor and pump, This single-phase motor and pump refrigerator compressor are the central components that make the refrigerator work.
There are many different types of refrigerator compressors such as Secop refrigerator compressor, Embraco Refrigerator compressor, Huayi refrigerator compressor, Donper refrigerator compressor, Panasonic, Samsung, LG, and other top brands.
A refrigerator compressor is used in high, medium, and low temperatures of residential or domestic refrigerators, freezers, or other small heat exchange equipment.

Types Of Hermetic Compressors Refrigeration System
When the both motor and compressor are limited to a steel shell, it is called a sealed or hermetic refrigeration compressor type.
The repairing option for this compressor is not very convenient so it is always replaced when an error occurs but the hermetic compressor is airtight and has no possibility of leakages.
According to the cooling system needs, many types of hermetic compressors are available to us.
Such as scroll hermetic compressors, reciprocating hermetic compressors, and rotary hermetic compressors.
It is ideal for small air conditioning and refrigeration systems as it’s not available for repairs,r such as for domestic, residential, or room AC units.
