What does Compressor mean?

A compressor is a mechanical device that reduces the volume of gas or vapor by increasing its pressure. It works by taking in a low-pressure gas or vapor and compressing it to a higher pressure, which reduces its volume. Compressors are used in a variety of applications, including air conditioning systems, refrigeration systems, pneumatic tools, and industrial processes.

There are different types of compressors, including reciprocating compressors, rotary compressors, and centrifugal compressors. Reciprocating compressors use pistons to compress gas or vapor, while rotary compressors use rotating impellers to compress the gas or vapor. Centrifugal compressors use high-speed impellers to accelerate and compress the gas or vapor.

Compressors are used in many different industries, including manufacturing, food processing, oil and gas production, and transportation. They are an essential part of many industrial processes and play a crucial role in providing power and cooling for various applications.

Application of Compressor

Compressor are used in many Application. Many of them involve to increase pressure of substances or fluid by reducing its volume. like….

Compressors have a wide range of applications in many industries and fields, including:

1. Air conditioning and refrigeration: Compressors are used in air conditioning and refrigeration systems to compress and circulate refrigerants that absorb and release heat, allowing for cooling or heating of indoor spaces.
2. Pneumatic tools: Compressed air is used to power pneumatic tools such as drills, impact wrenches, and sanders.
3. Industrial processes: Compressors are used in industrial processes such as chemical production, food processing, and manufacturing to compress and transport gases and fluids.
4. Oil and gas production: Compressors are used to transport and compress natural gas for storage, transmission, and processing.
5. Power generation: Compressed air is used to operate turbines in power generation plants.
6. Mining and construction: Compressors are used to power drills, jackhammers, and other equipment in mining and construction.
7. Transportation: Compressors are used in the air brake systems of trains, buses, and trucks.

Overall, compressors are essential in a wide range of applications, providing power and control for a variety of industrial and commercial processes.

• Compression of Air in Automobile industries.
• compression of Gases in petroleum and chemical industries.
• Compression of refrigerant in HVAC industries.
• Air storages for under water activities, filling tyres air.
• cabin pressurization in airplanes.
• gas turbine.
• pipeline.
• power pneumatics tools.

Types of Compressor.

There are several types of compressors, each with their own strengths and weaknesses, and they can be classified into three main categories:

1. Positive displacement compressors: These compressors work by trapping a fixed amount of gas and compressing it to a higher pressure. Positive displacement compressors include reciprocating compressors, rotary screw compressors, and scroll compressors.
2. Dynamic compressors: These compressors work by imparting velocity to the gas, and then converting the velocity into pressure. Dynamic compressors include centrifugal compressors and axial compressors.
3. Hybrid compressors: These compressors combine positive displacement and dynamic compressor elements to achieve high efficiency and performance. An example is the rotary vane compressor.

Here’s a more detailed overview of some of the most commonly used types of compressors:

• Reciprocating compressors: These compressors use a piston and cylinder to compress the gas. They are often used in small-scale applications, such as home air conditioners or small industrial processes.
• Rotary screw compressors: These compressors use two interlocking screws to compress the gas. They are often used in large-scale industrial applications and are known for their high efficiency and low noise levels.
• Centrifugal compressors: These compressors use a high-speed impeller to accelerate and compress the gas. They are often used in large-scale industrial applications and are known for their high flow rates.
• Scroll compressors: These compressors use two interlocking spirals to compress the gas. They are often used in small-scale applications, such as home air conditioners or refrigerators.
• Axial compressors: These compressors use a series of rotating blades to compress the gas. They are often used in aircraft engines and gas turbine power plants.

Compressor may be classified in different way. Commonly compressor are divided into type base on the function method used to generate compress fluid.

Here we have list out some commonly used compressor.

• Piston
• Helical screw
• jet compressor
• Sliding vane
• Scroll
• Rotory Lobe
• Centrifugal
• Axial
• Diaphgram

1. Piston

As a name suggest “Piston” Compression process take place between Piston and the Cylinder. Piston Move froward and backward with the help of Electric motor or any engine. When piston moves to its bottom, fresh air from surrounding enter in to the cylinder and compressed when piston moves bottom to top. after compression it pushed to storage tank.

2. Helical Screw

In Helical Screw Compressor, compression of air take place in the screw formed by coupling of rotors. The suction of air take place through suction port to the compression chamber. The Tooth space of Helical Screw Compressor is filled by air. when the rotor rotates in the reverse direction the suction opening get close. The compression chamber area get decreasing due to reverse rotation of rotors, the get compressed by reducing its volume.

3. Jet compressor

Type of Jet compressor are:-

• Hydraulic
• Gas and Vapour

Compressor that use falling water or water under pressure by applying pressure to air, without using any industrial moving parts. The simplest High-Level Water Body Exerts pressure on the air as it descends to low level. Subsequently, the water is immediately separated from the compressed air.

Gas Vapor Compressor are commonly used in HVAC field. Refrigerant gas enter in to the compressor with low pressure and and high heat, compressor compressed regrigerant in to high pressure and high heat then send to condensor.

Compressor used in HVAC fields

There are several types of compressors used in HVAC (heating, ventilation, and air conditioning) applications, including:

1. Reciprocating compressors: These compressors are often used in small- to medium-sized air conditioning and refrigeration systems. They are relatively inexpensive and have a simple design, making them a popular choice for residential and light commercial HVAC applications.
2. Scroll compressors: These compressors are often used in residential and light commercial air conditioning systems. They are known for their high efficiency, reliability, and low noise levels.
3. Rotary compressors: These compressors are often used in larger air conditioning and refrigeration systems. They are known for their high efficiency and durability, making them a popular choice for commercial and industrial HVAC applications.
4. Screw compressors: These compressors are used in large commercial and industrial HVAC systems. They are known for their high efficiency, reliability, and low noise levels.

The choice of compressor type depends on several factors, including the size of the HVAC system, the application requirements, and the desired performance characteristics. HVAC professionals will typically select a compressor that is the best fit for the specific application based on these factors.
