What is a Scroll Compressor?
A scroll compressor is an important component of a water chiller system, it works by compressing the cooler gas into a high pressure status. Compared to other types of compressor like screw compressors or piston compressors, this scroll type moves less when it works, thus it can provide you with a more quiet environment during the cooling process or even keep continuous operating for long time use.

How does a Scroll Compressor Work?
The working principle of a scroll compressor is to use the relative rotation of its two turbo shaped rotors to change the volume at the internal of the compressor.
During the actual working process, the intermeshing moving and stationary scrolls undergo relative motion driven by the motor. This movement changes the volume of the internal cavities, creating a pressure differential between the cavity interior and the exterior. This draws gas into the system. As the cavity volume continuously decreases, the internal gas undergoes increasing compression, and finally the gas will be discharged from the compressor as high pressure gas.
In fact, this is a continuous and smooth gas compression process that delivers high efficiency, this is also a reason why scroll compressors are widely used in the modern water chiller systems.
The Main Components of a Scroll Compressor
Intake Pipe
The compressor draws in gas through the intake pipe and compresses it.
Exhaust Port
Gas is discharged from the exhaust port. Within the chiller system, this gas flows into the condenser where it condenses into liquid. A check valve prevents gas flow backwards. Then, the liquid will return to the chiller’s evaporator to begin a new cooling cycle.
The Rotary and Fixed Scroll
As you know, scroll compressors have two spiral shaped components, one of them is stationary while the other can rotate. During rotation, a gas permeable cavity forms between the two scrolls. As this cavity shrinks in volume, it compresses the gas to generate high pressure air.
Compression Chamber
The compression chamber is a sealed crescent shaped cavity between two scrolls where air is compressed as the rotary shaft moves.
Cooling Fan
Generally, compressors are equipped with a cooling fan that dissipates heat from high pressure gases by blowing air over them. This also prevents overheating during pressurization, ensuring the compressor operates normally.
What are the Advantages of Using a Scroll Compressor on Your Water Chiller?
Simple Structure
Compared to other types of compressors, a scroll compressor has a simpler structure with fewer components. Consequently, a scroll compressor water chiller occupies a smaller footprint, making it suitable for applications with limited space.
Stable Operation
Due to its simple equipment structure and smaller footprint, a scroll compressor water chiller generates less vibration during operation. It requires no additional space for vibration damping, ensuring smoother running conditions that support stable long term performance and deliver extended service life.
Energy Saving
The simplified design of a scroll compressor water chiller delivers superior energy efficiency, this can reduce wear and vibration during operation and minimize the additional energy losses.
Consequently, scroll compressors typically exhibit a higher Coefficient of Performance (COP). This metric represents the chiller’s energy efficiency, a higher value indicates greater energy efficiency, resulting in lower electricity consumption and significant cost savings. This specific figure warrants careful consideration during the selection process.
Low Noise
The scroll compressor chiller’s minimal vibration during operation and its smooth air compression characteristics also result in lower operating noise levels. This feature makes it suitable for noise sensitive environments such as hotels and office spaces.
Low Maintenance Cost
As you can see, a scroll compressor has fewer components, this means that it is less prone to failure and requires less frequent maintenance, it is also easier for you to repair. This feature can save you significant maintenance costs and prevent frequent downtime that reduces efficiency.

How to Choose a Reliable Scroll Compressor Water Chiller?
Cooling capacity
When you are making specific selections, cooling capacity is the key parameter for evaluating a chiller’s performance.
You can calculate the required cooling capacity by using the following formula: Required Cooling Capacity (tons) = Water Flow Rate × Temperature Difference ÷ 0.86 ÷ 3.517. Once you obtain the specific value, you need to select a chiller with a cooling capacity approximately 10 to 20% higher than this figure to ensure sufficient operational capacity.
However, this formula can’t be applied universally. If your location experiences extreme high or low temperatures, or requires sub zero cooling, please contact our technical staff for more precise calculations.
