Air conditioners are becoming essential for every building thanks to our carelessness. You must be thinking, “How is our carelessness?” The answer is global warming. Though various types of air conditioners are part of our buildings, the AC chiller is a cooling machine that covers a significant area with many people, like offices or hospitals. Our entire blog is regarding the AC chillers guide. We will familiarize you with this device and let you know its pros and cons, parts, maintenance, and problems it can face. So, be our companion till the end because this is the time to decide whether it is worth it for you.

A little about AC chillers

Chiller AC units are popular for cooling large spaces and areas with high occupancy, such as offices and hospitals. These systems work like other air conditioners, efficiently removing heat from indoors and transferring it outdoors to maintain a comfortable indoor temperature, as their name suggests. Chiller AC units commonly utilize water or other cooling liquids within their system. The pumping mechanism inside these chillers manages the circulation of water or glycol solutions before directing them to a pumping system to cool the designated area effectively. Chillers have diverse applications, including cooling injection molding equipment, water chillers, and the food and beverage industry. Professional AC repair services are essential for maintaining and optimizing chiller AC unit performance.

Q. What is the working process of AC chillers?

The primary process is to produce hot and cold water via heat exchange between the cooling tower’s cooling water and the chiller’s refrigerant. Then, the water is sent to the heating and cooling terminal to perform the heating and cooling function.

Q. Is the installation process of the AC chiller easy or difficult?

The installation process of an AC can be complex and typically requires specialized knowledge and equipment, making it a task best suited for trained professionals. It involves intricate electrical and refrigeration work and precise system calibration.

Parts of chiller

Among our AC chillers guide, after a short introduction to the AC chillers is the parts of it. These devices mainly comprise four parts. Moreover, these parts are considered as the life of a device. Maintaining these devices and caring for them is a great idea to generate the maximum output and increase the life of a device.

  1. Compressor: Most HVAC compressors have a piston-driven vapor pump powered by an electric motor.
  2. Evaporator: The evaporator moves the heat from the water’s surface so that the chiller’s internal components can cool it.
  3. Condenser: After the heat has gone through the refrigerant, the condenser distributes it to the cooling systems outside.
  4. Thermal Expansion Valve: This valve controls the flow and pressure of the refrigerant coolant.

Q. Are ACs preferable to chillers?

Since air conditioning systems often cost less to install and operate, smaller companies that don’t require intense cooling find them particularly appealing. Additionally, they frequently use less energy than chilled water systems, which need electricity to power pumps and chillers.

Pros and cons

After observing the main components of the device in our AC chillers guide, it is best to put some light on its pros and cons because it is the factor that usually lets us decide whether it is good for us or not.

The Pros

First, we will let you know about the advantages of such devices.

1. Longevity of device

The first thing that makes people buy this device is the long lifespan of this device. It is because this device is designed to work for a long duration. Though technology also improves the longevity of other devices, a chiller has to cover a vast area but still runs for a long duration with proper maintenance, if required.

Q. What is the life of a chiller?

A chiller’s average life span is determined by its kind, moreover,  the lifetime of an air-cooled chiller is typically between 15 and 20 years. A water-cooled chiller typically lasts between 20 and 30 years. Your chiller’s lifespan may also be affected by location and environmental factors.

2. Non-Noisy device

Another trait that makes it the first choice among people is not producing noise when even functioning. AC chillers have two types: water-cooler chiller and air-cooler chiller. Because of this trait, it becomes challenging to know if the device is running or if it is a water cooler. At the same time, the air-cooler device comprises ducts and vents, which let it make a little noise but is still bearable.

3. Energy Efficient

If you ever go to an AC shop and see people purchasing devices, mostly their first concern is, “How energy efficient is it?” On the other hand, the good news for the purchasers of this device is that these devices are energy efficient.

4. No open space is compulsory

Water-cooled chillers are installed inside buildings, making them ideal for businesses that don’t have ample access to outside areas. When operating, air-cooled chillers need a wide open area with enough fresh air to remain outside.

5. Safety

Instead of using hazardous chemicals, water-cooled chillers employ water as a refrigerant. For those who interact with them frequently, this necessarily makes them safer.

The cons of AC chillers

Every action has its reaction. Likewise, everything has pros and cons. In the previous passages, we read about the advantages of AC chiller; now, it is time to observe its disadvantages.

1. Cost of the device

As this device aims to cover more area and number of people, high prices are not a surprise. At the same time, it offers a considerable lifespan compared to other devices, so spending a significant amount becomes valid in such cases.

2. Maintenance cost

For optimal performance, chillers need routine maintenance. Cleaning, fixing or replacing parts, and looking for refrigerant leaks are all examples of maintenance. These upkeep tasks may raise the total cost of ownership.

3. Impact on the environment

Many chillers employ refrigerants that, if they leak, might harm the environment. Older chillers could employ refrigerants that worsen global warming and ozone depletion. Although more ecologically friendly refrigerants are used in newer chillers, AC water leakage is still a possibility.

4. Complexity

The operation and maintenance of AC chillers call for highly qualified specialists. As troubleshooting and repairs may be more difficult due to this complexity, there may be a lengthier outage if problems occur.

Maintenance steps of AC chillers

As already discussed in the above passage, maintenance is an essential part of increasing the longevity of your device. In addition, changing the words to briefly express this statement: “Proper AC maintenance is life to chillers.” Have a look at the basic steps of maintenance of these cooling machines.

1. Regular cleaning

Clean the parts inside your air conditioner that help it work well, like the coils. Dirt and stuff can make it not work as well. You can use a soft brush or air in a can to eliminate the dust. Also, change or clean the air filter every month so the air can go through quickly and cleanly.

2. Check refrigerant

Sometimes, you should see if there is enough cooling stuff called refrigerant inside your air conditioner. If it’s not enough or there are holes, it won’t cool well and will use more electricity. If there’s a problem, fix it quickly.

3. Look at the electrical stuff

Check the wires and things that connect to the electricity. If they’re not good, your air conditioner might not work right and could be unsafe. Make sure everything is in good shape.

4. Oil and bearings

Put some oil on the parts that move, like the fan. Also, see if the bearings, which help things spin, are okay. Doing this helps your air conditioner work well and last longer. If the bearings are bad, change them.


In conclusion, this AC chillers guide has given readers insightful knowledge about the world of air conditioning chillers. Moreover, we’ve given you the information you need to make wise choices by emphasizing important maintenance advice, delving into the key elements, and balancing the benefits and drawbacks. Remember that proper maintenance assures top performance, and knowledge of the parts helps with troubleshooting. Energy efficiency and cooling capacity benefits must be weighed against drawbacks such as initial expense and space needs. Lastly, a well-kept chiller may be a dependable weapon in your cooling system’s toolbox.
