How does Air Chiller Work?

Air-cooled chillers assiduously absorb heat from process water.

They then push this heat into the air around the chiller.

However, this kind of chiller is usually used in areas where additional heat discharge is not a problem.

But instead performs as an advantage.

The process starts with the evaporator.

It has a fluid refrigerant that moves over the evaporator tube bundle where it evaporates.

Thus, in the cycle, heat is absorbed from the chilled water flowing through the bundle.

Further, the compressor then sucks the refrigerant vapor from the evaporator.

The compressor is then tasked with pushing the refrigerant vapor to the condenser, enhancing temperature and pressure.

Hence, the refrigerant gas condenses when it’s in the condenser tubes.

air cooled chiller parts

Thus, removing its internal heat to the air or cooling water.

Moreover, the high-pressure fluid then moves through the expansion part and into the evaporator.

Then in the cycle, the refrigerant pressure is decreased along with the temperature.

Lastly, to complete the continuous process, the refrigerant moves back over the chilled water coils and absorbs more heat.

Can An Air Chiller be Used Without Water?

To be accurate, Air Chiller will work without water as a straightforward fan as it were.

Thus, the hot air converts tin to cool air by evaporating the water through the air chiller’s evaporative pads. 

Without water in the Air Chiller, there will be no evaporation, and the air chiller will release hot air only.

What Sets Air Cooled Chillers Apart from Water Cooled Chillers?

Water-cooled and air-cooled chillers operate in a somewhat similar way.

Hence, they both have an evaporator, compressor, condenser, and expansion valve.

However, the main variation is that one uses air to fuel condenser cooling, and the other uses water.

-All chillers need basic sustenance to work at optimum levels.

However, air-cooled chillers are more comfortable and not expensive to retain than water-cooled chillers.

-Air-cooled chillers do not need a cooling tower or a condenser water pump.

-Air-cooled chillers use around 10% more power than a water-cooled unit; wet surfaces are better at transferring heat than dry surfaces.

Do Air-cooled Chillers Need Cooling Towers?

The chilling medium, ambient air, does not need any connections. Nor does a chiller with an air-cooled condenser need a cooling tower.

Thus, these installations have lower overall environmental concerns surrounding water treatment and removal.

Water Cooling Tower

What is The Difference Between A Cooling Tower And An Air Chiller?

Mechanical draft cooling towers depend on fans to attract cold air into the system to remove the water’s heat.

In contrast, Air Chillers use compressors, evaporator heat exchangers, and condenser heat exchangers. 

The condenser heat exchanger is the major part that releases heat from the chillers to the air.

  Figure 2 Working of an Air Chiller

Too high condensation pressure:

When there is too much refrigerant gas, and the outer air temperature is too high.

Moreover, the air chiller’s ventilation is not adequate, and there is air or non-condensable gas in the refrigerant system.

Thus, the condensation pressure will be too high.

Treatment method:

• release excess refrigerant;
• adjust and improve the ventilation environment around the air chiller (such as setting up a sun-proof shed);
• open the exhausted eye for exhaust,
• lower the cooling water volume,
• reduce the heat load,
• readjust the opening degree of the expansion valve,

Excessive suction, excessive heat pressure, improper adjustment of expansion valve may result in high suction pressure.

Too low condensation pressure:

The refrigerant gas maybe not enough, or the compressor is destructed.

However, assess whether there is leakage during treatment.

Hence after repairing, make up the refrigerant and test the compressor. If damaged, change it.

Air chiller is a type of chiller cooling system that is used in both industrial process cooling and commercial HVAC system spaces. It is one of the many types of water chiller systems in the market that you can choose from based on your cooling requirements.

The ideal use for an air chiller unit is to cool liquids for industrial processes and/or to dehumidify the air. You might have seen them used in restaurants, hotels, manufacturing and industrial plants, corporate and sporting events, and more.

You may use this type of chiller for temporary, emergency, or permanent cooling applications. There are plenty of air cooled chiller models that you can choose from so it is easy to choose the right system according to your needs.

To help you learn more about how air chiller works and the various uses for it, you can get more details below.

How does air chiller work?

In order to under what an air chiller system is and how it works, you must look into the air cooled chiller working principle. Please note that it is very common and has a lot of large scale applications but not too many people are aware of how it works.

The air cooled chiller diagram shows that this system has 5 main components: 1) compressor, 2) condenser, 3) condenser fans, 4) expansion valve, and 5) evaporator.

The compressor can either be one of three types: screw, scroll, or reciprocating. The condenser is made up of horizontal pipes that contain the refrigerant. It is also made up of several thin metal sheets within a vertical axis. This is responsible for distributing heat away from the tubes.

The condenser fan sucks air from the condenser coils and then forcing air out to the top of the unit. The expansion valve multiplies the refrigerant before it is fed into the evaporator where the chilled water is produced.

Meanwhile, the heat that is extracted from the chilled water is released back into the condenser. The same process is repeated in a cycle to maintain temperature for the air cooled chiller.

Understanding the different components of air chiller system is vital so you know how to properly maintain it. Each part of the system plays a vital role in its optimum performance – from the air chiller fan to the exterior components.

It is also important to know the type of compressor used as you need a different type of maintenance for air cooled scroll chiller as to that of the reciprocating or screw compressor types.

Does air cooled chiller use water?

An air cooled chiller works by absorbing excess heat from water. Once the water is processed, it warms up and sent back to the chiller. This is where heat transfer occurs and any excess heat from the water is removed before being sent back to the evaporator.

How does air chiller unit differ from air conditioner?

There is no such thing as chiller air conditioners. An air chiller should not be confused with an chiller air conditioning since they function differently.

An air chiller is designed to maintain industrial processes to provide cooling to large machinery and equipment that heat up when in use. They offer a higher cooling capacity with the ability to produce up to 2 degrees Celsius in temperature.

An air conditioner is designed to cool a particular space, such as a home or office. The cooling capacity of an air conditioner is measured in horsepower (HP) and it should be matched to the square footage of space. Most air conditioners can produce temperature of up to 16 degrees C only.

How much does an air chiller cost?

The cost of an air cooled water chiller will vary significantly based on a number of factors, such as the size and cooling capacity. The type of system can also determine its price. For example, a portable air chiller costs different from the stationary units.

The brand and manufacturer of the air chiller will also impact its cost. You can do your own price comparison but you will notice that the cost of air cooled chiller carrier will differ from air cooled chiller daikin, among other brands.

What are the types of chiller?

There are two types of air chillers that you can choose from: stationary and portable units.

A stationary air chiller is one that is recommended for applications when excess heat won’t be an issue. A portable chiller is one that is recommended if you require portability or there are limitations to installing stationary units.

What is the placement of air chiller?

An air chiller must be placed in mechanical equipment rooms or in an area that is within close proximity to where cooling is required. This is why industrial settings often have a dedicated room for the chiller equipment.

Therefore, it is important to consider the size of the chiller as it can be an issue during installation. There are also cases when air chillers are placed outdoors. You may consult a professional to know about the right placement.

What makes the air chiller system the coolest?

The cooling power of the air chiller system will depend on the size and capacity of the chosen unit. The ones available in the market range from 15 tons to as much as 500 tons.

Generating the right amount of cooling will depend largely on sizing your chiller correctly. If you are not sure how much cooling capacity you need, it is best to consult an expert.

Air cooled chiller vs water cooled chiller: what’s the difference?

Air cooled chillers operate differently from water cooled chillers although they work in a rather similar manner. Both of these systems are made of the same parts: evaporator, compressor, condenser and expansion valve. The primary difference between the two is that one uses air and the other water as fuel condenser.

Both types of chiller require the same level of maintenance to ensure its optimum performance. However, air chillers are preferred for industrial and commercial applications because it is less expensive to maintain than water cooled chiller units.

Air chillers do not require the use of a cooling tower unlike water cooled air chiller. Plus, they use up to 10% less energy to operate making it a more efficient choice for maximum savings.
