Takeaways

• 😀 Compressors are essential in daily life, used in refrigerators, air conditioners, and vehicle AC systems.
• 😀 Atmospheric pressure is 15 psi, but compressors increase this to over 10,000 psi to store compressed air.
• 😀 Air is the primary medium for compression in compressors, as liquids like oil and water cannot be compressed.
• 😀 A reciprocating compressor uses a piston to convert rotational motion into linear motion, creating high pressure for air storage.
• 😀 When the piston moves downward, it creates a vacuum, allowing air to enter the cylinder. The piston then compresses this air.
• 😀 As air is compressed, its temperature increases, which is why filters are used to remove dust and oil contaminants before compression.
• 😀 A two-stage compressor allows for higher pressure, with the first stage compressing air to 145 psi and the second stage reaching up to 300 psi.
• 😀 Spiral compressors, commonly used in modern air conditioners, are cylindrical in shape and feature a fixed and moving spiral to compress air.
• 😀 Centrifugal compressors, used in turbochargers and gas turbines, compress air using high-speed rotating impellers.
• 😀 Jet engines, a type of dynamic compressor, convert kinetic energy into pressure energy to propel an airplane forward.
• 😀 Ionic compressors, used for compressing hydrogen gas, employ a liquid piston mechanism to safely handle hydrogen without contamination.

Q & A

Why is the compressor an important part of our daily life?

The compressor is essential in various applications like refrigerators, air conditioning in homes and vehicles, and in industrial processes. It helps in compressing air to create high pressure, making it usable for cooling and other functions.

What is the typical pressure at which compressors operate?

The atmospheric pressure is around 15 psi, but compressors increase this pressure to much higher levels, typically up to 10,000 psi or more, which can be stored easily.

Why are compressors commonly called air compressors?

Compressors are generally referred to as air compressors because air is the main substance being compressed. Unlike liquids like oil or water, air is compressible, making it suitable for the process.

How does a reciprocating compressor work?

A reciprocating compressor works by converting the rotating motion of a motor into linear motion through a piston. The piston moves down to draw air in, then moves up to compress the air before it is stored in a tank.

What happens to the temperature of air when it is compressed?

When air is compressed, its temperature increases. Additionally, the friction between the piston and cylinder during regular movement further raises the temperature, which can lead to problems like cylinder damage if not properly managed.

Why are filters installed before the air enters the compressor?

Filters are installed to remove contaminants like dust and oil particles from the incoming air. These impurities can cause damage to the compressor, including overheating and potential cylinder explosions.

What is the role of the second piston in a multi-stage compressor?

The second piston in a multi-stage compressor further compresses air to a higher pressure, typically up to 300 psi. It benefits from the cooling effect of the first stage, where the temperature of the air drops before it reaches the second piston.

Why does the compressor in a refrigerator sometimes cause vibration?

When electricity supply is unstable, the compressor in a refrigerator may cause excess vibration. This happens due to issues with the compressor’s operation, and it is a common occurrence when the compressor is not receiving enough power.

What is the advantage of using a spiral compressor?

The spiral compressor is designed to be quieter and more stable than traditional compressors. It uses two spirals, one fixed and one moving, to compress air, and it reduces vibrations through counterweights, making it ideal for modern air conditioning systems.

How does a jet engine work as a compressor?

A jet engine functions as a dynamic compressor by converting the kinetic energy of air into pressure energy. As air moves through the engine, its velocity decreases while its pressure increases, creating forward thrust for the airplane.

What is the function of an ionic compressor, and where is it used?

An ionic compressor is used to compress hydrogen gas and other gases that require high purity. It utilizes an ionic liquid as a piston to compress gases up to 14,500 psi, and is commonly used in hydrogen fuel stations to refill vehicles.
