Other Chiller Types Related With Air Cooled Chiller

Air Cooled Chiller: The Ultimate FAQ Guide

Probably, you are looking for a high-quality air-cooled chiller.

Or, you’d like to learn more about air-cooled chillers.

Today’s guide explores all the critical aspects you need to know about these chiller systems.

So, if you want to be an expert in an air-cooled chiller, read this guide.

What is Air-Cooled Chiller?

An air-cooled chiller is a device that extracts heat from a load and transfers the heat to the environment.

It uses a fan or a refrigeration system.

These systems are common in most power plants.

Fluids are cooled by the refrigeration system.

This is possible with the help of air handling equipment.

What are the Components of Air-Cooled Chiller?

Components of an air-cooled chiller include:

  • Compressor: this is the driving force of the air-cooled chiller. The four main categories of compressors are/ include screw, scroll, reciprocating, and centrifugal.
  • Condenser: these are the pipes where the air is moved across the condenser to dissipate unwanted heat.
  • Condenser fans: the fans are the main components that differentiate between air-cooled and water-cooled chillers.
  • Evaporator/Expansion valve: this works with the heat exchanger to change the air from cold to hot and vice versa.

The three types of evaporators are brazed-plate, direct expansion, flooded shell-and-tube

  • Filter drier: protects the chiller from contaminants such as dust and should be replaced regularly.

How does Air Cooled Chiller Work?

An air-cooled chiller works through the following process:

Industrial-air-chiller

 Air-cooled chiller

  1. Heat absorption: this is achieved through the absorption process where the heat from the water is absorbed by the air-cooled chiller.
  2. Handler system: this allows the hot air that has been used up to be ejected out of the air-cooled chiller.
  3. Evaporator: This is a unit that blows hot or cold air to the atmospheric air that is infused into the system.
  4. Liquid refrigerant: this is where the water from the evaporator is turned to a gaseous form that is low in pressure.
  5. Compressor: the air from the evaporator that is in gaseous form and low pressure is compressed to a high-pressure gas.
  6. Condensers: this is where the exchange of gases happens, hot air is blown out while the clean air is blown inside through the fans.
  7. For efficiency purposes, it is recommended to place the air-cooled outdoors where there are no obstacles and the flow of air is uninterrupted. This will ensure the air-cooled chiller works at optimum.
  8. The main and important process of an air-cooled chiller is changing the liquid that is low pressurized to a liquid that is highly pressurized through the refrigerant.
  9. The process of changing low pressurized liquid to high pressurized liquid is a vicious cycle that requires the air-cooled chiller to work at optimum.
  10. This process is continuous and after the changing of the pressurized liquid, the process repeats according to how the air-cooled chiller has being set.

How does Air Cooled Chiller compare to Water Cooled Chiller?

Comparisons of air-cooled chillers and water-cooled chillers include:

Water-cooled-chiller

 Water-cooled chiller

  • A condenser is a component in air-cooled chillers that cools the air blown in.

On the other hand, water-cooled chillers comprise of condenser whose temperature is lowered by water connected with a cooling tower.

  • Air-cooled chillers are preferred for either large installations while water-cooled chillers are preferred for medium and smaller installations.
  • Water-cooled chillers are costly to operate and maintain than air-cooled chillers.
  • The water-cooled chiller’s specification is measured in kW/ton that ranges from approximately 0.55 and 0.8kW/ton.

That is different from an air-cooled chiller that has a different load.

  • Air-cooled chillers are preferably used in areas where water supply is not constant or where water is very expensive.

While water-cooled chillers are preferable in areas where water supply is sufficient.

  • Air-cooled chillers are preferred for all-weather use including freezing conditions, unlike the water-cooled chillers that cannot be used in winter conditions.
  • Unlike water-cooled chillers that need to be set up where there is a constant flow of water, air-cooled chillers can be set up at any location as long as there is a source of power.

Do Air Cooled Chillers require Cooling Towers?

Air-cooled chillers work at optimum is located at an open space where there is uninterrupted airflow and safe from hazards such as traffic.

Most of the air-chiller in a huge building and industrial use are located on the rooftop of the building.

How do you Specify Air Cooled Chillers?

  • Check for maximum temperature: Air coolers have a maximum ambient temperature of 40 to 45 degrees Celsius.
  • The minimum temperature: The temperature of air-cooled chillers ranges between -12 to 15 degrees Celsius.
  • Check for voltage: The voltage range of air-cooled chillers is 400 volts.
  • Capacity: The design capacity of air-cooled chillers is about 603 KW.
  • Check for airflow: The maximum airflow of air-cooled chillers is about 24.8 to 35 L/S.
  • Check the hydronic module: Air-cooled chillers have a built-in hydronic module.

What are the Applications of Air-Cooled Chillers?

Air-cooled chillers are purposely used for cooling purposes, they turn hot air to cold air and vice versa.

Some of the applications of air-cooled chillers include

  • They are used in large industries to cool production processes and machinery.
  • They are used in huge residential buildings to cool hallways and common areas.
  • Are used in large scale industrial cool rooms to keep products such as meat and vegetables fresh.
  • Used in hospitals for air circulation purposes.
  • Some are installed in tracks and vans that transport fresh produce or highly perishable products.
  • Air-cooled chillers are also popular in the retail environment where large stores use them for cooling purposes.

How do you Maintain Air Cooled Chillers?

I. Daily maintenance procedures for air-cooled chillers will entail:

  • Turning off or sequencing unnecessary chillers
  • A complete inspection of the air-cooled chiller to ensure that all the equipment is operating and there is safety.
  • Checking off all the setpoints to ensure proper setting and function.

II. Monthly maintenance procedures for air-cooled chillers will entail:

  • Assessing condenser and evaporator coil to ensure it is as required.
