How Much Does a Scroll Chiller Cost?
Depending on the type of scroll chillers, you will pay between 2500 and 60,000 US dollars.
You realize that there is a huge price gap between the different types of chillers.
This is due to many reasons.
The prices vary due to many reasons including varying scroll chiller sizes and quality.
Implying that the greater the quality and size of a scroll chiller, the higher the cost of the scroll chillers.
High-quality scroll chillers use very high-quality materials which are costly hence the high prices.
What are the Components of the Cooling System of the Scroll Chillers?
The chilling system of scroll chillers has numerous parts that work in conjunction with one another to produce a chilling effect.
Here are the main components of the scroll chillers that you ought to know more about.
· Compressor
This is the core component of the scroll chillers which provides the refrigerant with enough pressure to move through the chillers.
In other words, the scroll compressor will help in converting the input energy into mechanical energy on the refrigerant.
· Condenser
You will depend on the condenser to eliminate the heat from the refrigerant thus condensing it from gas to liquid state.
It will use the help of cool air or water flowing through the system to get rid of the heat thus leaving the refrigerant condensed.
· Cistern
This is a reservoir within the condenser that receives the refrigerant and contains it for a while as it condenses the refrigerant.
In other words, it will act as a container that allows the refrigerant to make good use of the cooling system within the condenser.
· Dry Filter
The dry filter will help in getting rid of any moisture by drying it off from entering the main system of the scroll chillers.
Apart from that, it acts as a filter that blocks the entry of dirt from entering the scroll chillers’ main system.
· Thermal Expansion Valve
It acts as the flow regulation valve as well as the throttle valve in the scroll chiller system.
It is responsible for reducing the pressure of the refrigerant while maintaining low temperatures.
· Evaporator
This is the point where the refrigerant will collect the heat that comes from the industrial application system.
It uses the evaporation system to absorb heat from the cooling system and transfer the heat to the refrigerant.
· Refrigerant
This is the fluid that is capable of changing form from gas to liquid while collecting and depositing heat from the chillers.
There are two main types of refrigerants that you can use in scroll chillers which include R22 and R12.

How does Scroll Chillers Work?
There are two types of scroll chillers which include air-cooled chillers and water-cooled chillers.
Both of them apply the same working principle except for the fact that they will employ water or air to get rid of heat.
Here is a step-by-step process on how the scroll chillers work.
1) Refrigerant Circulation System
The main working principle of the scroll chillers depends greatly on the circulation of the refrigerant through the chiller system.
The process will begin from the refrigerant’s main storage area which will release the refrigerant from the storage tanks.
The refrigerant will then flow in its liquid state from the storage tanks into the compressor system.
2) Refrigerant Compression
As soon as it arrives at the scroll compression system, it will undergo compression which will provide the refrigerant with pressure.
The scroll compressor uses the two interleaving scrolls where one scroll is inside the other to compress the refrigerant.
It will compress the refrigerant more quietly and smoothly thus converting input energy to mechanical energy.
This increases the pressure and volume of the refrigerant allowing it to flow at high velocity to the evaporator.
3) Heat Absorption
The evaporator is responsible for collecting the heat from the flowing cooling water.
In other words, it has a series of pipes running through the evaporator with water containing the heat.
It employs the evaporation system to get rid of the heat from the flowing water thus leaving the water chilled.
Here, the refrigerant will absorb the heat from the evaporator and change from a liquid state to a gaseous state.
It has enough room for collecting a considerable amount of heat due to the high-volume capacity of the refrigerant.
After that, the gas refrigerant, laden with a lot of heat will flow at the same speed and pressure to the condenser.
4) Elimination of Heat
This is the point where the scroll chiller will use the help of cool air or cool water to eliminate the heat from the refrigerant.
The refrigerant, flowing at the same speed and pressure, will flow straight into the cistern, a storage unit within the condenser.
The cistern will give the refrigerant ample time to make use of the flowing cool water or air and eliminate the heat.
In the process of heat elimination, the refrigerant will condense, changing from gaseous state to liquid state.
As soon as it is cool, it will flow to the expansion valve while the air or water eliminates the heat.
The expansion valve will control the high pressure and volume of refrigerant to lower levels that the scroll compressor can handle.
