TopChiller® is a professional chiller/chiller unit/chiller system manufacturer and supplier with over 20 years’ experience.
Chiller sometimes called chiller unit and chiller system is one kind of refrigeration machine that providing consistent cooling water for industrial processes and commercial applications.
The chiller can be divided into the air-cooled chiller and water-cooled chiller based on the cooling method can be divided into scroll chiller and screw chiller in terms of compressor types.
The chiller can also be divided into regular temperature chiller and low temperature/glycol/brine chiller based on the chiller temperature controlling range.
Generally, the chiller consists of four main parts: compressor, evaporator, condenser, expansion valve, so as to achieve the refrigeration effect of the chiller.
The working principle of a chiller is like this:
The liquid refrigerant driven by the compressor in the evaporator absorbs the heat in the water and starts to evaporate.
At last, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant is also completely evaporated into a gaseous state and then absorbed and compressed by the compressor (pressure and temperature increase).
The gaseous refrigerant absorbs the heat through the condenser (air-cooled / water-cooled), condenses into a liquid, and becomes a low temperature and low pressure through the thermal expansion valve.
The refrigerant enters the evaporator to complete the chiller refrigerant circulation process.
Chiller is a kind of cooling water equipment that can provide constant temperature, constant current, and constant pressure.
Chiller, chiller unit or chiller system plays an important role in most industries and commercial air conditioning usages.
In the air conditioning system, chilled water from the chiller is usually distributed to heat exchangers or coils in the AHU or other types of terminal equipment for cooling in their respective spaces, and then the cooling water is redistributed back to the condenser for cooling.
In industrial applications, chilled water from the chiller is used to control products at a proper temperature and cooling industrial machine or process.

What is the Working Principle of a Chiller?
Chillers depend on three main principles that control all the operations in a bid to cool different applications.
Here are the three main principles that control how chillers work.
· Phase Change
First, a liquid coolant will have to go through a phase change from the liquid state into a gas state after heating.
Apart from heating, the gas will also go through a chilling process where it will condense back to a liquid state.
· Heat Flow
The second principle involves the flow of heat energy from a high concentration area to a low concentration area.
· Boiling Point
Here, the principle will involve the reduction of pressure in a liquid in order to reduce the boiling point of the liquid.
At the same time, there are instances where the machine increases pressure to increase the boiling point.
Which Types of Chillers are There?
There are quite a number of chillers in the industry that you can use for a number of applications.
The main difference between the chillers is the cooling agent or refrigerant in use to produce a cooling effect.
Here are the main types of chillers that you will use in different applications.
· Air Chiller
Air-cooled chillers use air as the main agent to help in controlling the temperatures within the chillers.
It uses the air running through the parts of the air chilling system to reject heat in the condenser from the refrigerant.
· Water Chiller
Water chillers use water that comes from external cooling towers to create a colling effect within the chiller applications.
It is capable of rejecting heat from the gaseous refrigerant within the condensers before undergoing phase changes to the liquid state.
· Portable Chiller
A portable chiller is a device that you can move from one location to another with ease.
It can either use the water-cooling or the air-cooling system to create a chilling effect within the application.
· Central Chiller
A central chiller is any type of chiller that you can employ in the process of cooling several processes in different applications.
It can either be water-cooled or air-cooled and can also have a portable or stationary application.
· Industrial Chiller
The industrial chiller is a type of chiller that you will use in different industrial applications to cause a chilling effect.
It can either be an air-cooled or a water-cooled type of chiller which cause the chilling effect within the industrial application.
Most industrial chillers are stationary due to the huge size even though you might find some that are portable.
· Modular Chiller
This is a smaller type of chiller which you can easily combine with other modules to make a larger operational machine.
Modular chillers often come complete with either a single or a double independent refrigerant circuit.
· Glycol Chiller
Glycol chiller uses propylene glycol as well as anti-freeze mechanisms to cause a chilling effect in various applications.
It is the most suitable type of chiller that you will use in a food-grade application such as alcohol production and brewery systems.

It is a quieter and more compact type of chiller with very few parts in comparison to other types of chillers.
· Centrifugal Chiller
Centrifugal chillers have additional rotating impellers responsible for compressing and transporting refrigerants around the system of the chillers.
You will employ and use them in the medium as well as large scale cooling operations.
· Oil Chiller
This is a special type of chiller that you will use in the cooling of hydraulic oil, cooling oil, and lubricating oil.
Oil chiller can also use any mechanism such as air cooling or water cooling to help in controlling the oil temperatures.
How Does the Water-Cooled Chiller Compare and the Air-Cooled Chiller Compare?
There are two main cooling or chilling mediums that you can use in the chillers which are air and water.
Implying that we have two main types of chillers which are the air-cooled chillers and water-cooled chillers.
Below is a comparison that will give the direct difference between the air- and water-cooled chillers.
· Water-Cooled Chillers
This type of chiller features a water-cooling tower and a condenser which help in cooling the system.
You will use it in applications and mediums that have enough supply of water.
It is independent of fluctuating air temperatures thus making it the most reliable type of chiller for different applications.
It is available in different sizes ranging from small 20-ton chillers to big water-cooled chillers for controlling larger installations.
You will need a mechanical room to install the water-cooled chillers thus protecting it from the external weather elements.
· Air-Cooled Chillers
This type of chiller usually depends on a condenser which is also relieved of high temperatures by the environmental air.
It is the most suitable type of chiller to use in small and medium-sized installations with minimal space requirements.
Apart from that, it is the best chiller to use in environments that have a problem of water scarcity.
It is cheaper to install in comparison to the water-cooled chillers and you will not need a mechanical room.
Due to the outdoor elements, the lifespan of the air-cooled chillers is often shorter even though it requires low maintenance.
What are the Main Parts of the Water-Cooled Chillers?
The water-cooled chillers depend on different parts to help in eliminating excess heat thus causing a chilling effect.
Below are the main parts of the water-cooled chillers that help in the operations of the machine.
The compressor is responsible for the creation of a pressure difference thus moving the refrigerant around the whole system.
The compressors are available in different types including screw, centrifugal, scroll, and reciprocating compressor.
You can find the condenser just before the expansion valve and after the compressor.
It is responsible for the removal of heat from the refrigerant which the refrigerant picks up from the evaporator.
· Expansion Valve
The expansion valve is the part that you will find between the evaporator and the condenser.
It is responsible for expanding the refrigerant thus increasing the volume and reducing the pressure.
It will help in picking up the heat that the chiller is trying to get rid of.
You will find the evaporator between the compressor and the expansion valve of the water-cooled chillers.
It is responsible for the collection of heat and moving it to the refrigerant before it goes to the cooling tower.
· Power Unit
You can either have the power unit on the chillers or in a separate position on the walls of the production plant.
You will use the power unit to control electrical power flow through the water-cooled chillers.
· Control System or Unit
You will use the control system to make the necessary adjustments and monitor the chilling process of the water-cooled chillers.
It also helps in protecting the machine by generating alarms and automatically shutting down the machine in case of malfunctions.
· Water Tanks
The water tanks assist in directing the flow and segregating the exit as well as the entrance of water.
You will find the water boxes on the condensers as well as the evaporators of the water-cooled chillers.
How Does the Water-Cooled Chiller Work?
Water-cooled chillers use recirculating condensers from the cooling tower to condense a refrigerant.
It has a pumping system that is responsible for the circulation of cool water from the chillers to the processes.
The cool water will eliminate the heat within the processes as it flows back to the water-cooled chillers.
As that occurs, the water heat from the process will reduce thus causing a cooling effect within the process.
Through the refrigerant cycle, the water-cooled chillers are capable of eliminating the heat from the water.
It involves a process where the refrigerant goes through a heating and cooling process where it expands to vapor.
Later, it can condense back to liquid form when it passes through a cooling agent.
Once the low-pressure gas or liquid flows to the evaporator, heat within the liquid will boil the refrigerant.
Remember that the heat in the liquid will come from the processes which produce heat.
As soon as it starts boiling, the refrigerant will change from low-pressure liquid to low-pressure gas.
After that, the low-pressure gas will move into the compressor which will change it into a high-pressure gas.
It will flow from the compressor and into the condenser which will eliminate the heat from the refrigerant.
It will condense into a cool liquid with high pressure which will travel to the expansion valve.
The expansion valve will then control the quantity of refrigerant that will flow to the evaporator.
This will be the beginning of another cooling process using the water-cooled chillers.
What are the Main Parts of the Air-Cooled Chillers?
Air-cooled chillers have various components that assist in its operations.
Below are the main parts of the air-cooled chillers which play a huge role in its operations.
Parts of an air-cooled chiller
Air-cooled chillers have compressors which will help in moving the refrigerant around the entire system.
It can either have any of the four types of compressors which include scroll, reciprocating, screw, or centrifugal compressors.
The condenser consists of configurations of horizontal pipes that allow refrigerants to flow through the system.
Air will move across the condenser to help in the removal of the unwanted heat.
· Condenser Fans
The condenser also has fans which will help in blasting enough air to remove heat from the refrigerant or system.
· Expansion Valve
It is responsible for expanding the refrigerant from the liquid form and changing it to a gaseous form.
After that, it will guide the gas into the evaporator.
· Heat Exchanger or Evaporator
The evaporator is responsible for eliminating the heat from the refrigerant thus forming a chilled liquid refrigerant.
· Filter Drier
The filter drier is responsible for the removal of unwanted debris such as moisture among other contaminants.
It is important to replace the filter driers on a regular basis as they might clog and affect the performance of the chiller.
How Does the Air-Cooled Chiller Work?
The main working principle of the air-cooled chiller is the absorption of heat from the refrigerant by blasting air.
It has fans that are in constant rotation thus enabling the proper flow of air over the pipes in the condenser.
As soon as the water flows through the processes in the air handling systems, it usually becomes warm or hot.
Implying that, it will absorb the heat from the processes and transfer the heat within the water or refrigerant.
As soon as the water reaches the evaporator, there will be heat transfer involving the elimination of heat from the water.
As the refrigerant moves over the evaporator tube, it will evaporate and create a low-pressure system.
The evaporated refrigerant will then flow to the compressor which will compress it into a high-pressure gas.
After that, the gas will flow all the way to the air-cooled condensers where blowing air will help in eliminating the heat.
The cooled refrigerant in form of liquid will flow back to the process to absorb more heat thus continuing the process.
How Do Vapor Compressor Chillers Compare to Vapor Absorption Chillers?
Vapor condenser chillers use different refrigerants to help in cooling different process fluids as well as spaces.
It has a compressor which acts as the main driving force that drives the refrigerants through the entire system.
On the other hand, the vapor absorption chillers do not have compressors within the unit.
It uses another source of heat such as solar energy to drive the coolant through the entire system.
How Does the Absorption Chiller Work?
Absorption chillers often have coolants within the evaporators which turn into a gaseous state.
Within the chiller is a concentrated absorbent such as ammonia which comes from the liquid absorbent generator.
The dilute solution of liquid-absorbent will absorb the coolant and allow the cooling water to absorb the heat.
A dilute solution of the absorbent and coolant will flow through the heat exchanger all the way to the generator.
While at the generator, the solution will be heated and eliminate the coolant from the solution through evaporation.
It will flow to the condenser which will condense it into a liquid and send it back to the system to continue the process.
It will also recycle the absorbent after eliminating the heat from the system.
What are Glycol Chillers?
Glycol chillers are particular types of chillers that use an antifreeze such as propylene glycol to create a chilling effect.
It is the most suitable chiller that you can use in food chilling applications such as alcohol products in breweries.
Which Factors Determine the Cost of the Chillers?
Well, the chillers are available for you to purchase at different prices depending on quite a number of factors.
Since we have different types of chillers, you expect to have different price tags on the chillers.
For instance, water-cooled chillers often cost a lot more than air-cooled chillers.
Apart from that, the size of the chiller will also affect the price as the bigger the chiller the higher the cost.
Generally, the cost of chillers often ranges from 5,000 to 250,000 US dollars depending on the above factors.
Which Actions Should You Take to Increase the Efficiency of the Chiller Systems?
The maximum efficiency of the chiller system will help in reducing the cost of managing the chillers to a great extent.
Here are some of the factors that you should take into consideration to increase the efficiency of the chillers.
· Performing Ongoing Maintenance
Your chiller system will work more appropriately through proper conduction of ongoing maintenance.
This should be part of your maintenance system which involves inspecting and cleaning condenser coils.
Apart from that, you should maintain good levels of refrigerant charge as well as maintenance of the condenser water.
· Performing Predictive Maintenance
In this case, you can use particular artificial intelligence technology to predict potential part failures.
This will allow you to perform proper maintenance on the machine before the prediction causes a catastrophic failure.
· Optimizing the Performance
You should also optimize the operations of the machine by doing proper calibration of parts to perform at optimum levels.
It is a holistic approach that you must approach with a lot of care to ensure you get the right dimensions.
How Does a Reciprocating Chiller Compare to a Rotary Screw Chiller?
Reciprocating chillers have compressors and internal pistons that compress the refrigerant that come through the intake valves.
With enough pressure, the refrigerant will flow through an exhaust valve where it goes to the system for more heat absorption.
It has the capability of accommodating cooling loads ranging between 30 and 150 tons.
It is also very flexible and allows you to use multiple units at the same time.
On the other hand, the rotary screw chillers use the rotary screw compressors to operate to its maximum capacity.
It has helical rotors that are responsible for the compression of the refrigerants.
It forces the refrigerant into the into particular spaces that the helical screws create within the cylinder.
This forces the gas to flow along the length and exits of the rotor when it reaches the other end of the rotor.
They are mid-range units capable of handling between 20 to 1000 tons.
It also has very few moving parts with a very high compression ratio thus making them have a smaller size.
What is the Difference Between a Centrifugal Chiller and a Scroll Chiller?
Centrifugal chillers use impellers that help in driving the refrigerant against the walls of the cylinder chamber.
After that, it will exhaust the refrigerant thus continuing with the chilling circle.
It is capable of handling very large volumes of refrigerants using multiple impellers due to small compressive force.
It also has the greatest capacity reaching 2000 tons and works well in applications that need 300 tons and more.
On the other hand, scroll chillers, are the smallest types of chillers in comparison to all the other types of chillers.
It is capable of handling load between 5 and 150 tons with double offset spiral disks that are nested together.
They require low maintenance due to the compact nature thus making them very efficient.
What is the Vapor- Compression Chiller Technology?
Vapor compression technology uses a compressor to help in creating a chilling effect using the chillers.
It uses any of the four compressors which include scroll, reciprocating, centrifugal, and screw-driven compressors.
How Does Absorption Technology in Chillers Work?
This type of technology uses a particular source of heat to drive the refrigerant through the chiller systems.
It has low electricity requirements that run both the refrigerant pump and the solution pump.
It uses a dilute lithium bromide solution to absorb refrigerant which has the heat from the processes.
It will pass through compressors which will increase the pressure of the solution and change it to a gaseous state.
After that, it will form a solution that will flow through the chiller to the condensers which will condense it and eliminate the heat.
The flowing cool water will eliminate the heat from the system and the diluted lithium bromide flows to the original position.
What is Industrial Chiller Technology?
Industrial chiller technology is a complete package that involves a complete loop of a system capable of handling industrial applications.
Normally industrial chiller comes complete with a water tank that will ensure the constant flow of water through the systems during industrial applications.
In some industrial chillers, you will have refrigerants that replace water or air to help in the cooling process.
What is the Use of a Refrigerant in a Chiller?
The refrigerant in the chiller is responsible for the absorption of heat within the chiller system.
There are different types of refrigerants that you can use which include R12 and R123 depending on the application.
Which is the Right Location for Placing a Chiller?
You can wither place a chiller inside the mechanical room or outside the building.
This will, however, depend on the type of chiller that you are using.
Water-cooled chillers are best for installation inside the mechanical room to maintain its efficiency.
Since the air-cooled chillers require air to work well, you can place it on open ground outside the building,
In case you place it in the mechanical room, you must have enough ventilation for the air-cooled chillers.
How Do Industrial Process Chillers Compare to HVAC Chillers?
You can either decide to use the HVAC chillers or the Industrial process chillers in chilling applications.
Before you make a choice, here are the differences that you should note between the two types of chillers.
- Both industrial and HVAC chillers have independent refrigeration circuits.
- The HVAC system, however, does not have an independent water circuit that the Industrial chillers have.
- The cost of installing the HVAC chillers is often high due to the availability of independent parts that require installation.
- You can purchase the industrial chillers straight from the manufacturer due to its considerable big size.
- HVAC chillers are smaller and you can purchase them from the local distributors which might be costly.
Which Features Do You Look at When Choosing a Chiller?
When shopping for a chiller, there are particular features that you must have in mind before choosing the chiller.
Here are the main features that you look at before you choose a chiller.

You don’t have to go through extensive training and the chiller must not cost more during the maintenance period.
Can You Use a Standard Chiller in Heat Recovery Applications?
Yes, you can use the standard chillers in heat recovery applications.
All you have to do is set the application requirements according to the heat recovery requirements.
So, instead of eliminating heat, the system will provide enough heat that will warm the processes.
How Does a Freezer and a Chiller Compare?
A freezer and chiller are two different types of devices that cause a chilling effect within different applications.
You will, however, use the freezer to create extremely cold temperatures that the chiller cannot manage.
Apart from that, you can use chillers in very large industrial applications that the freezer cannot manage.
The freezer also consumes a lot of power in comparison to the chillers.
How Do You Troubleshoot a Chiller?
Well, there are circumstances when the chillers fail to work due to particular problems in the system.
You can easily identify the problems within the system by troubleshooting the device.
Here are some of the problems that you might encounter in the process.
· Low- and High-Pressure Trip
This is often a result of a problem with the refrigerant or the cooling system which might experience inconsistent water flow.
In this case, you will have to check on the sources of the refrigerants and the water supply to sort the situation.
· Oil Failure Trip
Here, you might go through an oil failure trip as a result of low oil or heat due to leakage and damages to the pump.
In this case, you will have to repair the pump and replace the damages along with the hydraulic system.
You can also increase the amount of heat that you supply to the system to enable proper oil flow.
· Freeze Start
The problem with the freeze start is often a result of poor flow of water or low settings on the thermostat.
You can sort it out through proper calibration of the machine to ensure the flow of water and set the thermostat well.
· Starter Trips or Blown Fuses
This can be as a result of over-amped motor or shorted wires and compressors.
In this case, look at the ground installations before you proceed with the operations.
What is a Heat Recovery Chiller?
The heat recovery chiller is a system that will eliminate heat from the cooling load within the evaporator.
It will later recover the heat rejection from the condenser of the chiller on its way to the cooling towers.
It employs the chilling process to enable proper heat recovery in the entire system.
How Does a Heat Recovery Chiller Work?
During the cooling process, the chiller will produce and control the amount of chilled water from the evaporator.
As that happens, the condenser will dissipate heat absorbed by the refrigerant in the processing section of the industry.
When the need arises for either hot or chilled water, the system will switch to the heat recovery mode.
Instead of eliminating the heat from the system, the heat recovery mode will
It will then channel the heat that it recovers into other heating modes that enable proper energy-saving modes.
What Does Cooling Capacity in Chillers Mean?
Cooling capacity is the measure of the systems within the chiller to remove heat from the entire system.
It calculates the ability and time it takes for a particular chiller to eliminate heat from the entire system.
The S.I unit of the cooling capacity of the chiller is in Watts (W).
How Do You Increase the Efficiency of the Chiller?
Well, there are three main modes that you can employ to increase the efficiency of the chillers.
Here are the main factors to consider in order to increase the efficiency of the chillers.
- Consider the speed of the retrofits using the variable speed drives.
- You can run multiple devices in parallel mode thus making the system more efficient in saving energy.
- You can also increase the temperatures that you supply by the application of reset control of supply air temperatures.
What is the Process of Cleaning the Chiller Tube?
It is very important that you look at the maintenance of the chillers on a very serious note.
Implying that you should clean the chiller tubes on a regular basis to avoid malfunctions.
Here are the basic steps you will perform during the cleaning process of the chiller tube.
- You will remove the valve from the system chillers.
- After that, you will drain the condenser and get rid of the debris within the condenser.
- At the same time, you must also drain the evaporator.
- Remove the end and headcovers on the tubes.
- After that, you should brush all the evaporator and condenser tubes using a good brush.
- As soon as you complete that, you will proceed with the cleaning of the gaskets.
- In case of damages, you will have to replace the broken parts on the chillers.
- Finally, you will assemble all the parts of the chillers before you begin operations.
What is the Function of the Anti Freeze Mechanism in the Chillers?
You will need the anti-freeze mechanism in your chiller to help protect the chiller from flash freezing damages.
It will help in protecting the chillers from the freezing process and low ambient conditions.
How Do You Reduce Energy Consumption on the Chillers?
There are quite a number of factors that you can control in a bid to reduce excess consumption of energy.
Here is an overview of the factors that you can consider to reduce energy consumption.
- Reduction of energy consumption by using different system-based designs

Filters in the chiller systems are responsible for blocking any form of contaminant from entering the system.
It will eliminate the contaminants from the system thus avoiding any form of damage on the chillers.
What is Chiller Efficiency in a Chiller?
In the normal operations of a chiller, there are particular factors that you can consider to increase its efficiency.
Here are the main strategies to look at in order to increase the efficiency of the chillers.
- You need to have a daily operation log that you update on a frequent basis.
- You have to keep the tubes of the chiller clean at all times.
- Ensure that the entire unit does not have leaks
- You must also have proper sustenance of power and water treatment.
- Do proper analysis on the refrigerant as well as the oil on a regular basis.
How Do You Determine the Right Size of Chiller that You Need?
You need to choose the right size for a chiller depending on the type of application you are working on.
To determine the right size of the chiller that you need, you can use the chiller sizing tool to determine the proper sizes.
The chiller sizing tool will help you in the determinations of the load tonnage, size, as well as chiller capacity.
How Does an Air Conditioner Compare to a Chiller?
The main difference between the AC and the chiller is in the working principle as well as the size.
The AC is smaller in size in comparison to the chillers which are often quite big.
Apart from that, the AC is a device that you will install inside the house to cool the room.
On the other hand, chillers are best located outside the house or inside a mechanical room depending on the type of chillers.
Speaking of location, AC is more durable than the air-cooled chillers as they are not exposed to derailing weather elements.
What are the Quality Standards of Chillers?
You have to ensure that your chiller meets the highest quality levels when it comes to testing the machine.
In that case, the main quality standards that your chillers must adhere to include:
- EN 12309-2 Quality Standards
- DIN 33830-4 Quality Standards
- JIS B 8622:2009 Quality Standards
- ANSI/AHRI 560 Quality Standards
- ANSI/ASHRAE 182-2008 Quality Standards
- VDI 4650-2 Quality Standards
- EN 15316-4-2 Quality Standards
- RAL-UZ 118 Quality Standards
You have to note that the above quality standards are for ensuring the quality of different aspects of the chillers.
How do you Test Chillers?
Well, to ensure that the chillers are of absolutely high quality, you have to test it using different testing procedures.
Here are some of the tests that you can perform on the chillers to ensure high quality.
· Factory Acceptance Test (FAT)
You will perform the FAT while the machine is still at the factory before you transport it to the right destination.
· Installation Qualification Test (IQ)
It is also important to perform the necessary tests on the machine after you complete the installation process.
· Operational Qualification Test (OQ)
Finally, you need to set the machine on the operational mode and test how good the machine works.
You have to remember that the testing should follow a particular procedure and with respect to particular quality standards.
Clearly, depending on your needs, you can choose chiller systems that meet the specific requirements of your applications.
