Below is the major content of this article:

1. What Is Air-Cooled Chiller?

Also based on cooling methods, chillers can be divided into air-cooled chillers and water-cooled chillers based on the cooling method.

Now we come to the topic of air-cooled chillers, Air-cooled chillers are the most popular compared to other types of chillers because of easy operation and low maintenance costs.

Air-cooled chillers are cooling systems that are widely utilized in various places, mainly industrial and commercial constructions, to provide consistent cooling water for their usages.

2. How Does an Air-Cooled Chiller Work?

Now we all know air-cooled chillers are dispensable for various industries. Do you know how these air-cooled chillers work?

I. Basic Working Principle

Generally, air-cooled chillers use the evaporator to take in the heat from chilled water, then the compressor takes away the vapor generated during this process and the vapor is pressurized and heated in the compressor.

Afterward, the vapor is released into the air-cooled type condenser. Eventually, the vapor pushes the heat out to the ambient air.

Due to pressurization and cooling, the refrigerant moves in cooled tubes where its temperature is reduced.

Finally, the refrigerant goes back over the chilled tubes and assimilates more heat and this makes the whole procedure become a cycle, thus providing continuous cooling from an air-cooled chiller.

This is the whole working diagram of an air-cooled chiller.

TopChiller Air Cooled Chiller Introduction

II. Key Components of Air Cooled Chillers

In the first part, we have learned the basic working principle of air-cooled chillers, now let’s delve deeper into some key components of these cooling machines.

An air-cooled chiller mainly consists of a compressor, evaporator, condenser, throttle device, water pump, water tank, electronic controlling system, and cooling fans.

Compressor: Among all the refrigeration components of the air-cooled chiller, the compressor is the most important one working as the power of an air-cooled chiller.

Its function is to compress the low-temperature gas into a high-temperature gas and then exchange heat with other media in the heat exchanger.

Danfoss and Copeland Scroll Compressor in air-cooled chiller

Evaporator: Frankly 3 types of evaporators can be used in an air-cooled chiller– stainless steel water tank with the coil, stainless steel plate heat exchanger, and shell&tube heat exchanger.

For an air-cooled chiller, it is generally using a water tank coil type evaporator.

#304 Stainless Steel Water Tank

Some air-cooled chiller end-users also choose a brazed plate-exchange or closed-loop shell and tube-type evaporator according to their needs, this is also no problem.

Its function is to use liquid low-temperature refrigerant to evaporate at low pressure, convert the refrigerant or cooling gas into steam and absorb the heat of the cooling medium to achieve the purpose of refrigeration.

#304 Stainless Steel Brazed Plate Heat Exchanger

What’s the function of the evaporator of the air-cooled chiller? The evaporator performs under continued certain pressure and makes all the liquid evaporate.

The evaporator creates a low-pressure space where the refrigerant is evaporated and absorbs all the heat during the process.

Close-loop Shell and Tube Evaporator

Condenser: the function of an air-cooled type condenser is to cool the refrigerant steam discharged from the compressor into a liquid or gas-liquid mixture.

Let’s know something about air-cooled condenser as below:

Air Cooled Condenser Introduction

The heat of the air-cooled chiller released by the refrigerant in the condenser is carried away by air. This is a space where the refrigerant exchanges the heat and finishes the transfer.

Air Cooled Condenser

Throttling Devices: Throttling devices are also an important part of an air-cooled chiller. In general, the throttling devices are thermal expansion valves.

Let’s have a general idea of how thermal expansion valve works:

How Thermal Expansion Valve Works

When the refrigerant or cooling gas from the condenser passes through the throttling device-thermal expansion valve, its pressure and decreases greatly, and as a result, the temperature of the refrigerant drops down as well.

The throttling devices- the thermal expansion valves mainly function as a method to reduce the pressure of the refrigerant: The refrigerant is at high pressure after it leaves the compressor.

We need to lower the pressure of the refrigerant so that it can vaporize at the desired temperature in the evaporator.

The orifice in the throttling valve lowers the pressure of the refrigerant to the point where the vaporization can take place.

This is the function of an expansion valve for an air-cooled chiller.

Thermal Expansion Valve

Water Pump: Normally for standard air-cooled chiller models, there should be a built-in water pump.

There are the vertical type and horizontal type water pumps, both types are centrifugal water pumps.

The water pump installed in an air-cooled chiller is designed to increase the pressure and the flow of the chilled water in a closed-loop system. The water pump must be configured properly to achieve the desired outcome.

Vertical Type Centrifugal Water Pump

Insufficient pressure and flow will not produce enough cooling and even worse, more heat will be generated due to the high cooling load.

However, if there is no control of speed, excess pressure and flow will make the electrical system be under a heavy burden, and as a result, the electricity is wasted due to excess pumping.

Anymore, all pumps of air-cooled chillers should be under-insulated to keep a good cooling efficiency.

Water storage tank: For a standard air-cooled chiller, there should be a water storage tank. The water tank is also called a buffer tank, which is used to increase the system’s capacity and stabilize water temperatures within the chiller.

It’s usually made of stainless steel and a buffer tank is needed when storage is required to ensure water volume is sufficient and the temperature is under control, thus better ensuring the day-to-day operation of the system.

The outer of this water tank also should be covered with heavy insulation.

Electronic control system: The role of a control panel for an air-cooled chiller is to control the values and other devices in the system as well as monitor the operation status during the procedure.

Exhaust fan: An exhaust fan is a device equipped with one or more blades to propel the airflow.

Fans help to force out the extra hot fumes and make room for clean air to create a more comfortable working environment for the equipment.

Good quality air-cooled chiller fans can greatly improve thermal efficiency.

3. Industrial Applications of Air Cooled Chillers

Air Cooled Chillers are very important auxiliary machines or devices for model industries.

In industrial applications, air-cooled chillers are commonly used in the production process or laboratory equipment.

Air-cooled chillers are widely used in all kinds of industries for controlling product quality or cooling machines.

Air-cooled chillers are applied for anodizing, beverage, blow molding, cement cooling, chemical process, HVAC, hydraulics, injection molding, laboratory, office buildings, lasers, molding, plastics, pharmaceutical, printing, semiconductor, thermoforming, vacuum forming, welding, etc.

Air-cooled chillers can be custom-made to meet different needs in industrial applications. Each type has its advantages.

Here are some detailed examples of industrial applications of air-cooled chillers.

I. Plastics

The plastic and rubber field is the most popular industry for air-cooled chiller applications.

In the plastics industry. An air-cooled chiller can also cool down the hot plastic and the molding equipment, which can create big savings on energy consumption and on the maintenance of the machines that are used to produce plastic products, this is the plastic chiller working process.

Air-cooled chillers can greatly improve the surface of plastic products, eliminate surface marks, and relieve the internal stress of plastic products.

By doing so, the plastic products do not shrink or deform easily, which facilitates their moldings.

As a result, the production efficiency of molding machines is significantly upgraded by air-cooled chillers.

The cooling capacity required is in direct proportion to the injection volume of the molding machine, this is Air Cooled Chiller for Plastic machines.

II. Anodizing

There will be a huge amount of heat generated in the process of anodizing, which makes cooling become a necessary part, especially for hard coating.

Air Cooled Chiller for Anodizing

Air-cooled chillers will remove the heat in the process usually requires an air-cooled chiller that is installed outside the workshop.

Air-cooled chillers can stabilize the metal ions and non-metal ions, and then the metal ions quickly attach themselves onto the electoral part, oxidated part, and electrophores part.

This process can increase the density and smoothness of the products.

In addition, if the temperature of the anodizing liquid is higher than the standard required in the procedure, the finished product will inevitably be affected in terms of firmness, uniformity, flatness, and appearance.

Therefore, air-cooled chillers are what should be taken into consideration if the producers desire to sharpen their electroplating techniques, this is how Air Cooled Chiller is used for Anodizing.

III. Laser

In the laser cutting industry, the air-cooled chiller is mainly used in laser machines, such as laser marking and engraving machines, laser welding machines, laser printers, laser cutting machines.

The air-cooled chiller can be also used for cooling laser machines or laser processes so that we call it is laser chiller.

Laser chiller can precisely control the temperature required by laser equipment, thus ensuring the constant normal operation of laser equipment, this is Air Cooled Chiller for Cooling Your Laser Machine.

IV. Pasta and food

The pasta and food need to be cooled down rapidly when processing at high temperatures. This needs to use an air-cooled chiller.

However, the temperature of cooling water cannot be too high; otherwise, the tempering quality will be affected.

The chilled water provided by air-cooled chillers is used to cool down the water, and the water temperature will be immune to the temperature around, to ensure the quality of pasta and food products. This is why Air Cooled Chiller Used for Pasta and food industries.

V. Beverage

Air-cooled chillers can be also found in the beverage processing industry.

During the production of confectionery, beverages, beer, milk, yogurt, and other foods, the quality of the beverage and food mixture will be influenced if the heat is massively generated during the production process.

Therefore, it is necessary to cool all the processes by using an air-cooled chiller and achieve to maintain the temperature. This is Air Cooled Chiller for Cooling Your Beverage Process.

4. The Difference Between Water Cooled Chillers and Air Cooled Chillers

When we’re discussing air-cooled chillers, water-cooled chillers are a topic we can’t avoid mentioning.

Industrial businesses use either air-cooled chillers or water-cooled chillers to realize the cooling effect.

So what’s the difference between the two?

We can go to have a look at this video to get a rough idea about this topic.

The Difference Between Water Cooled Chillers and Air Cooled Chillers

Both kinds of air-cooled chiller and water-cooled chillers are composed of a compressor, an evaporator, a condenser, and a thermal expansion valve.

As water has a higher capacity, using water-cooled chillers to remove heat is traditionally more efficient than using air-cooled chillers.

In addition, water-cooled chillers tend to endure longer than air-cooled.

However, air-cooled chillers can be installed outside, which means there is no need for physical space for air-cooled chillers.

This makes an air-cooled chiller a great solution for stationary cooling.

Both types of chillers have their benefits.

Air-cooled chillers and water-cooled chillers both perform under similar principles to transfer heat and create a cooler environment.

But they use different components to cool the different condensers.

The difference is that the water-cooled chillers use water consumption while the air-cooled chillers need an air-cooled condenser as the aid of airflow.

Let’s take a closer look at the air-cooled chillers based on the following points.

I. What Are the Benefits of Air Cooled Chillers?

If we take environmental conditions and water consumption into consideration, the air-cooled chiller is the better solution for our future.

Generally, air-cooled chillers work in a closed-loop system, which can provide instantaneous cooling and save water at the same time.

This is essential particularly in regions where water is in shortage.

Air-cooled chillers are easier for operation as they spare the trouble of cooling towers. The closed-loop system enables users to reduce maintenance costs compared to water-cooled units.

In summary, here are the advantages of using air-cooled chillers instead of water-cooled chillers:

• No need to install a cooling tower
• Better environmental protection and greater environmental sustainability
• Lower maintenance costs
• Easier for installation and operation
• Easier to handle and control
• No extra interior space needed

You can find Air Cooled Chiller advantages over Water Cooled Chiller

II. Types of Air Cooled Chillers

Air-cooled chillers can generally be divided into two types: stationary air-cooled chillers and portable air-cooled chillers.

Stationary Air Cooled Chiller: stationary air-cooled chillers are installed outdoors and have a better cooling capacity.

Portable Air Cooled Chiller: portable air-cooled chillers are easier to install and remove. They are ideal for temporary applications because there are moving wheels on the bottom of the air-cooled chiller.

5. What You Should Consider When Buying an Air-Cooled Chiller for Your Business?

There are all kinds of air-cooled chillers in the marketplace.

When buying an air-cooled chiller, we always need to look at the following points.

I. Efficiency

An excellent air-cooled chiller should be able to deliver the optimum performance at either part-load or full-load status, which will help cut the operating costs to the lowest level.

Some basic aspects need to assess before we judge whether your air-cooled chiller is efficient or not.

We can check if the sound of the fans.

If the air-cooled chiller operates and produces too much noise, the air chiller unit cannot be defined as efficient.

However, if the propeller fans can perform at the low sound level, then that air-cooled chiller deserves our attention.

The exhaust fans in TopChiller® air-cooled chillers are low in sound level and they operate smoothly with little vibration and this makes the air chillers suitable for sound-sensitive workplaces.

II. Performance

Performance is the factor we always need to take into account when we are purchasing mobile phones, tablets, or household goods. but air-cooled chillers are no exception.

Across a wide range of chillers, all kinds of chillers are designed to operate under certain temperatures, from the lowest temperature to the highest temperature.

In addition, the cooling capacity is also a factor that reflects the performance of an air-cooled chiller. It usually ranges from dozens to hundreds (tons).

TopChiller® has designed a series of air-cooled chillers whose cooling capacities range from 0.2 Ton to 550 Ton.

TopChiller® is capable of producing chillers in other ranges based on customers’ needs. Please contact us to get the price of the air-cooled chiller.

III. Affordability

If your company has a budget for air-cooled chillers, there is a key factor that you cannot avoid paying attention to affordability.

The sales prices of products or services in the marketplace are mainly affected by building rent, labor costs, and operating costs.

Therefore, never say a product or service is better because it is more expensive. We have to look at the products or services themselves.

If you are selecting an air-cooled chiller, here is a tip. Don’t choose based on price. Choose based on its seller and performance.

If you compare the performance between the two sellers, you will know which one is better.

TopChiller® air-cooled chillers not only excel in terms of performance but are at low prices as well, this is the reason why TopChiller® has maintained a foothold in the industry over nearly two decades.

Some advice on air-cooled chiller regular maintenance

The air-cooled chiller was originally designed with multiple protection devices, which have played a significant role in its use.

However, however, how many heavy protection devices are designed, and as the air-cooled chiller equipment is used for a longer period, the service life of various components of the air chiller equipment, this air-cooled chiller equipment will have various problems.

To ensure the high cooling efficiency and long service life of your air-cooled chiller, we need daily maintenance and regular maintenance of all air-cooled chillers.

1. Regular cleaning of air-cooled chillers
When the air-cooled chiller is running for 6 months, the whole system should be cleaned, such as pipes, filters, condensers, fans, etc., especially the fan.

Like an air-cooled chiller using exhaust fans, it is covered with dust and affects heat dissipation. Therefore, cooling efficiency will be a direct reduction.

2. Check if the refrigerant is reduced.
This can be judged based on the high and low-pressure gauge values ​​on the front of the air-cooled chiller.

When the air-cooled chiller is in normal operation, the high pressure is 11-17kg, and the low pressure is 3-5kg. In the shutdown state, the high pressure and low pressure are all-around 0.6kg.

3. Regularly troubleshoot air-cooled chiller to avoid sudden problems happen

Make sure to drain out the tank water if the air-cooled chiller is no use for a long while when your factory is closed or on holiday time.

3. What are the Major Components of an Air-Cooled Chiller?

The Air Cooled Chiller has six major components.

Compressor

The compressor provides the main push to move the refrigerant around the system.

There are four primary kinds of compressors.

Three of them (screw, scroll, and reciprocating) utilize positive replacement to make pressure, and the fourth (centrifugal) makes pressure with centrifugal power.

Condenser

The condenser is a setup of horizontal pipes by which hot refrigerant moves.

Air is gotten across the condenser to disseminate unwanted heat.

Condenser Fans

These fans address the major difference between Air Cooled Chiller and water-cooled chillers.

As they transfer air across the condenser, unwanted heat is eliminated from the system so the process can start from the very beginning once again.

Expansion Valve

The expansion valve produces the refrigerant from fluid form to gaseous form before it enters into the evaporator.

Evaporator/Heat Exchanger

In the evaporator, chilled water is produced when unwanted heat is brought into the refrigerant before it is taken care of into the condenser.

Filter Drier

6. How does an Air-Cooled Chiller Work?

The Air Cooled Chiller has a very common working principle.

The Air Cooled Chiller will provide “chilled water” which is pumped out around the building to the air handling units (AHU’s) and fan coil units (FCU’s) which eliminate the unwanted heat from the building and move it into the chilled water loop.

The chilled water will go through the AHU’s/FCU’s at about 6°C (42.8°F) and when it leaves the heat exchanger in the AHU/FCU it will raise to about 12°C (53.6°F)

At that point go back to the Air Cooled Chiller to dump this heat into the atmosphere before repeating the cycle.

The water getting back from the process goes through the evaporator by the recirculation pump.

Air Cooled Chiller effectively absorbs heat from process water; then moves this heat into the air around the Air Cooled Chiller.

This kind of Air Cooled Chiller is normally utilized in the area where extra heat discharge isn’t an issue yet works as an advantage.

For example, the extra heat can be utilized to warm space throughout the winter for less money than an ordinary heating system.

The process starts with the evaporator, which has a fluid refrigerant that floes over the evaporator tube bundle where it evaporates.

All the while, heat is absorbed from the chilled water circling through the bundle.

The compressor then pulls the refrigerant vapor from the evaporator.

The compressor then pumps the refrigerant vapor to the condenser, which expands the temperature and pressure.

The refrigerant condenses when it’s in the condenser tubes, carrying its inner heat to the air or cooling water.

The high-pressure liquid at that point moves through the expansion valve and into the evaporator.

In this process, the refrigerant pressure is reduced alongside the temperature.

To finish the continual cycle, the refrigerant flows back to the chilled water coils and absorbs more heat.

The set temperature is maintained by the control board, partializing the cooling limit provided by the compressor depending on the actual cooling load required.

8. What is the main distinction between Air Cooled Chiller and Water Cooled Chiller?

Air Cooled Chiller and water-cooled chiller has many things in common.

The Air Cooled Chiller and water-cooled chiller both belong to a similar vapor pressure chilling family, and both utilize an electronically driven mechanical compressor to force refrigerant around the system.

Indeed, most of their parts are the same.

An Air Cooled Chiller mostly consists of screw or scroll compressors and a water-cooled chiller mostly has a screw or centrifugal compressor.

The basic difference between an Air Cooled Chiller and a water-cooled chiller is the way unwanted heat is ejected from the system.

A water-cooled chiller pump water through a sealed condenser and throw it through a cooling tower.

Air Cooled Chiller uses fans to drive cool air across the condenser.

An Air Cooled Chiller consumes around 10% more power than a water-cooled chiller; a wet surface is far better at moving heat than a dry surface.

A water-cooled chiller’s cooling pump and tower occupy more room than the fans in an Air Cooled Chiller.

Because of this major part difference, the Air Cooled Chiller has a more solid impression.

Cooling towers are likewise more costly to maintain, making Air Cooled Chiller a clear lower maintenance option.

All chillers require essential maintains to perform at ideal levels, however, an Air-Cooled Chiller is simpler and more affordable to maintain than a water-cooled chiller.

In general, the Air Cooled Chiller is less expensive.

12. How to Troubleshoot your Air Cooled Chiller Problems?

Air Cooled Chiller is a very expensive product so if you are not a qualified person or do not have enough knowledge so it can be risky to solve your Air Cooled Chiller problem on your own.

So if you are not qualified or authorized to work on your Air Cooled Chiller at that stage you should call a professional to resolve your Air Cooled Chiller problems.

High-Pressure Discharge:

High pressing discharge happens with your Air Cooled Chiller when the condenser’s outside surface gets covered with dust.

Over the long run, your Air Cooled Chiller condenser will get covered in a film of dust.

So you need to ensure that all the tubes and fins are cleaned consistently.

However, remember that the tubes out there are full of refrigerant and they are delicate so be careful when you clean these.

Utilize light brushes and some combs fins too while cleaning it.

Minerals and dust particles will be absorbed from the air, into the condenser water loop.

This will at that point flow around the system and start to obstruct the lines and your Air Cooled Chiller heat exchanger.

So it essentially begins to protect the internal surfaces of your Air-Cooled Chiller condenser which will keep your Air-Cooled Chiller prevent from moving its rated thermal energy.

Reduction of Air Flow:

Another basic issue, with an Air Cooled Chiller, is a reduction of airflow over the condenser.

This is generally happening were some trash has hindered part of the condenser or the fans.

Thus insufficient air is flowing through the condenser to remove all the undesirable heat.

It could likewise be that one of the fans has quit working or not working properly.

So you need to go up there and outwardly watch that they’re clean, it’s free from obstructions, and that the fans are working properly.

Low-Pressure Discharge:

One issue that causes low-pressure discharge is if the suction valve is incompletely shut, so check that. It’s genuinely exceptional however it could occur.

Refrigerant undercharge can be the cause of the low-pressure discharge.

You will need to check on the system to that it has a sufficient refrigerant charge.

If you presume that this is the issue, it should be topped up.

Another issue could be that the ambient air temperature is excessively low.

Air Cooled Chiller will be unable to work in these conditions and there’s very little you can do about that. You could heat the air, intentionally cause re-circulation or direct the building’s ventilation to extract air toward it.

The most common issue for low-pressure discharge will be a dirty or a deterred evaporator. So check nothing is hindering this.

Low-Pressure Suction:

This can happen due to the low refrigerant charge.

Check around your system for indications of this and top up if necessary. Remember to check for leaks also.

If the pressure becomes too high in your Air Cooled Chiller, it may have vented through the safety valves.

Another one of the most common issues with this will be a blocked expansion valve. So you may need to clean this or replace it if necessary.

It could likewise be that there’s a decrease in inflow into the evaporator.

So once more, you need to check all the valves, bypass valves, and pumps to ensure that they’re all working properly.

You must also check the filter drier and the strainer of your Air Cooled Chiller. If they’re blocked, clean these or replace them.

High Suction Pressure:

If your Air Cooled Chiller has a high-pressure warning on the suction line, three primary things that can cause this.

The excessive load is most likely the principal cause and that is the place where the cooling load is simply a lot for your Air-Cooled Chiller to handle.

You need to decrease that if possible. Or spread this over to different other chillers and cooling equipment.

Electrical Faults:

An irregular voltage supply to your Air-Cooled Chiller can cause deficiencies.

You need to check your voltages on every one of your phases to ensure that they are adjusted.

It could demonstrate that there’s an issue with the electrical switchgear inside your building or power quality issues.

Controls:

A genuinely basic reason for the error is the point at which the flow sensor is broken, particularly the paddle-type sensors.

Before your Air Cooled Chiller will turn on, it needs to check that there is the right flow going through the evaporator and the condenser to keep it from freezing.

Be that as it may, if the paddle gets wedged, loses communication, or builds up a fault it’ll presently don’t quantify or send the signal back to the control unit.

Your Air Cooled Chiller will accept that there is no flow or insufficient flow and it will turn itself off and won’t begin again until there’s sufficient flow.
