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 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 them from the external weather elements.

· Air-Cooled Chillers

You will find the water boxes on the condensers as well as the evaporators of the water-cooled chillers.

Water cooled chiller highly efficient heat exchanger

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 their operations.

Below are the main parts of the air-cooled chillers which play a huge role in its operations.

· Compressor

Air-cooled chillers have compressors that 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.

· Condenser

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 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

Air cooled chiller controller

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 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 that 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 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.
