A centrifugal air system, also known as a centrifugal compressor, is a type of air compressor that uses centrifugal force to compress air. It is a dynamic compressor, which means that it works by imparting kinetic energy to the air, which is then converted into pressure energy. The centrifugal air system consists of a rotating impeller that is housed in a casing. The impeller is equipped with blades or vanes that spin at a high speed, creating a centrifugal force that draws in air through the inlet and accelerates it towards the outer edge of the impeller. As the air moves towards the outer edge, its velocity and pressure increase. The high-velocity air then enters a diffuser, which is a stationary component that converts the kinetic energy into pressure energy. The diffuser slows down the air, causing it to increase pressure and decrease velocity. The compressed air then exits the compressor through the discharge outlet.
The centrifugal air system is commonly used in large-scale applications such as power generation, oil and gas processing, and chemical processing. It is preferred in applications where large volumes of compressed air are required at high pressures, as it can deliver a high flow rate of compressed air while maintaining a relatively constant discharge pressure. The centrifugal air system is not typically used for processing food products. Instead, it is primarily used in large-scale industrial applications such as power generation, oil and gas processing, and chemical processing. However, in some cases, compressed air is used in the food industry for various applications such as food packaging, filling, and conveying. In these applications, oil-free compressed air is required to ensure the safety and quality of the food products. Rotary screw or scroll compressors are commonly used in the food industry as they can provide clean, oil-free compressed air at high flow rates and pressures. It's worth noting that while compressed air may be used in the food industry, it is not typically considered a food product and does not directly come into contact with the food products being processed. The working principle of a centrifugal air system involves the use of a rotating impeller to compress air. The process can be divided into several steps: Intake: The centrifugal compressor takes in air through an inlet located at the center of the impeller. The air is drawn into the impeller due to the low pressure created by the high speed of the impeller blades. Acceleration: As the air passes through the impeller, it gains kinetic energy due to the high speed of the rotating blades. This kinetic energy increases the velocity of the air and creates a centrifugal force that moves the air towards the outer edges of the impeller. Compression: As the air moves towards the outer edge of the impeller, it encounters a diffuser, which converts the kinetic energy into pressure energy. The diffuser slows down the air, causing its velocity to decrease while its pressure increases. The compressed air then exits the compressor through a discharge outlet. Cooling: The compressed air produced by the centrifugal compressor can become very hot due to the adiabatic compression process. To prevent damage to the compressor and downstream equipment, the compressed air is usually cooled using an aftercooler or a heat exchanger. The centrifugal air system is capable of delivering high volumes of compressed air at relatively high pressures. It is commonly used in large-scale industrial applications where a continuous supply of compressed air is required. The system is also known for its low maintenance requirements and high reliability, making it a popular choice for many industrial applications Market Insight of Centrifugal Air system The market for centrifugal air systems is primarily driven by the increasing demand for compressed air in various industrial and commercial applications.
