Scroll Chillers: The Ultimate FAQ Guide

Before you buy scroll chillers, read this guide.

It has all information you need to know about scroll chillers such as parts, working principle, increasing efficiency, and quality tests, just to mention a few.

Keep reading to learn more.

What are Scroll Chillers?

Scroll chillers are special types of chillers that use the scroll compressor to produce a chilling effect on different industrial equipment.

It uses two interleaving scrolls where one scroll is within the other to compress the refrigerant.

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 a number of reasons.

The prices vary due to a number of 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.

Parts of chiller

 Parts of chiller

· 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 the air-cooled chillers and water-cooled chillers.

Both of them apply the same working principle except for the fact that it 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’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 high pressure and volume of refrigerant to lower levels that the scroll compressor can handle.

How do you Install Scroll Chiller?

You should install the scroll chillers in a place that has proper ventilation and allows free flow of air.

Here is a step by step process that you should follow when installing your scroll chillers.

· Selecting Site

You will begin with the process of looking for the perfect site where you will install the scroll chillers.

In this case, you will consider an open place with proper ventilation to avoid large water vapor, acid, and dust.

In case you intend to install more than one scroll chiller, you must maintain a 3-meter distance between them.

This will help in eliminating the possibilities of impedance if you place them too close to one another.

· Laying the Connections

This is the point where you will install the pipes and the valves that will service the small chillers with water or air.

You must look at the right dimensions of the pipes that will match the specifications of the scroll chillers.

In terms of piping connections, you must use soft valves and joints to service the piping connections.

After that, you will connect the pipes and ensure that they are tight enough to avoid lose connections.

· Placing the Scroll Chillers

As soon as you complete the whole process of laying down the pipes, you will proceed with the placement of the scroll chillers.

This is the point where you will need a technician to help in carefully placing the scroll chillers at the right position.

After that, you will proceed with connecting all the valves and joints of the pipe on to the scroll chillers.

You must also be very careful and tighten the connections well to avoid leaks and pressure differences.

· Inspection Stage

At this point, you will inspect the entire scroll chiller as well as the connection between them.

You will also go back to the source of the fluids and check their compatibility with the coil materials.

It is important to know that the fluid might require treatment and you must provide that option.
