How Does a Scroll Compressor Chiller Work?

A Scroll Compressor Chiller works on the principle of evaporation and condensation. The Scroll Compressor Chiller acts as a refrigerator to cool the fluids and cool in the system, dehumidifying the air in the surroundings of a system.

A Scroll Compressed chiller is mostly used in the industrial, hospitals, and commercial sectors these days. The Scroll Compressor Chiller does its working process by using its main components.

• Evaporator
• Condenser
• Compressor
• Expansion valve

Evaporator:

The Scroll Compressor Chillers start working with the evaporator.

In the evaporation, the reservoir is filled with some measured amount of water. Many tubes are present that surrounds the evaporator chamber.

These tubes surrounding the evaporator contain the liquid that helps the water to cool down.

The cycles start in the evaporator where the liquid refrigerant flows over the tubes that are present around the evaporator.

The liquid refrigerant is a chemical that can absorb the heat from the water running in the tubes around the evaporator chamber.

As soon as the refrigerant reaches the boiling point, it starts converting into vapors.

Compressor:

Vapors that are produced, start to pass through the compressor. The compressor utilized in a Scroll Compressor Chiller is named the Spiral Compressor and falls into the water-cooled chillers category.

The Scroll Compressor Chiller comes into action while taking vapors. With its distinctive spiral design and two interleaving scrolls, the compressor starts to pump, compress and pressurize the fluid.

 Condenser:

The compressor of the Scroll Compressor Chiller then starts to raise the temperature of the condenser by pumping the vapors into the condenser.

The liquid starts to condense in the condenser tubes transferring its heat to the cooling water.

Expansion Valve:

This high-pressure liquid refrigerant coming from the condenser is then passed over the expansion valve to decrease the pressure as well as the temperature of the refrigerant.

Heat is being transferred out of the system resulting in the production of the cooling effect.

Re-cycling of the Cooling Process

After that, the compressor is again connected to the condenser, to again complete the loop by linking back to the evaporator to continue the cycle of cooling production.

This Scroll Compressor Chiller is liked because of its noise-free working performance.

Scroll Compressor Chiller Applications

How a Scroll Compressor Chiller is Different from a Screw Compressor Chiller?

Screw Compressor Chiller

A screw compressor chiller is a type of chiller that compresses air due to screw action.

The main benefit of using this screw compressor chiller is that it provides compressed air continuously with the lowest variation in conveyance pressure.

It is mostly used for low-pressure applications up to 8 bars. A screw compressor Chiller uses rotors to compress larger volumes of gaseous refrigerant to high pressure and temperature.

The compression process in the Screw compressor chiller is performed by male and female rotors that lessen the refrigerant gas volume as they rotate for action

Scroll Compressor Chiller

Compared with Screw compressor Chiller, a Scroll Compressor Chiller is used to compress a larger scroll. The cool vapor refrigerant is transferred in Scroll Compressor Chiller from outside the fixed scroll.

It compressed the refrigerant between the fixed and the orbital scroll, and at the end, the compressed refrigerant is cleared out from the center of the fixed scroll with a continuous displacement.

Classification

The Scroll Compressor Chiller can be further classified based on its drive speed (constant and variable. The Screw compressor chiller can be sub-classified by the number of screws a chiller have.
