What Are Industrial Chillers Used For?

An industrial chiller is different from a residential HVAC system because it requires more power and cooling efficiency. The industrial application of chillers involves cooling in manufacturing processes, laboratories, factory machinery, heavy mechanisms, and many other large-scale uses.

Industrial Chillers Application

How Does An Industrial Chiller Work?

Industrial chillers use either water or ambient air as a refrigerant. It can also be powered by any one of four types of compressors: rotary screw, reciprocating air, axial, and centrifugal compressors. Depending on the type of compressor, there are different components, number of parts, and functions.

However, the purpose remains the same, which is to produce a cooling effect for buildings and commercial spaces.  

Figure 2 Industrial Chillers

How Many Types Of Chillers Are There?

There are two general types of chillers in the market. They are air-cooled and water-cooled chiller systems. They differ mainly in terms of the cooling principle but their function remains the same.

What Is A Screw Type Chiller?

A screw-type chiller, or screw compressor chiller, uses either water or air as a refrigerant. In a water chiller, the compressor is on top of the chiller unit. For an air chiller, the compressor is underneath.

When use in an indoor setting, the water-cooled chillers will have insulation whereas air chillers will have none.

What Are Three Types Of Compressors?

There are four types of compressors use din chiller systems: rotary screw, reciprocating air, axial, and centrifugal compressors.

• The rotary screw compressor consists of two internal rotors as its main components. It is best for chiller systems for continuous use and for large scale applications.
• A reciprocating air compressor operates using a piston that is inside a cylinder. It is ideal for smaller applications such as home renovations. It is not intend for continuous use.
• A centrifugal compressor, also known as a dynamic compressor, makes use of rapidly rotating air blades in order to draw air into the system. Like rotary compressors, it is also for large-scale uses such as manufacturing plants and industrial buildings.
• The axial compressor is the most expensive type of compressor for chiller systems. It is the best suit for airplanes and other high-speed engines.

What Is The Difference Between HVAC And Chiller?

Air conditioning units (HVAC) isfor residential use, or small buildings and offices. They are available in numerous sizes with limited cooling effect. On the other hand, chiller systems are built for large-scale use such as commercial or manufacturing plants. They are capable of more powerful cooling and can withstand continued use.

How Does A Chilled Water HVAC System Work?

A chilled water HVAC system is typically installed in the roof or any external part of the building. As the name implies, it is built on a chilled water system wherein it uses cooled water to produce a cooling effect.

This type of HVAC system is capable of generating anywhere from 4 to 7 degrees Celsius in cooled air. It is introduced into the building through pipes that are integrated into the building.

Do Chillers Use Refrigerant?

Yes. A refrigerant is needed in order to remove unwanted heat from the air or water whenever it is processed between the evaporator and condenser. When the heat is removed from the refrigerant, it is a pump to the rest of the system in order to produce a cooling effect on the building or home.

This entire process is repeated once the refrigerant is once again collected and processed through the evaporator and condenser.

What Are The Main Components Of A Chiller?

The main components of a chiller are: 1) compressor, 2) condenser, 3) evaporator, 4) expansion valve, 5) power panel, 6) control unit, and 7) water box.

The compressor is the primary mover and is responsible for developing pressure variation that will process the refrigerant. The condenser is behind the compressor and is to remove heat from the refrigerant.

water cooled Process Chiller Components

The evaporator is in between the compressor and expansion valve. It collects the waste heat from the structure and processes it along with the refrigerant before it is connected to a cooling tower. The primary function of the expansion valve is to aid in lowering the pressure on the refrigerant and maximizing its volume.

The power panel is responsible for managing the flow of electrical power into the chiller system. The control unit is where you can access the different functions of the system. The water box directs the flow inside the chiller and differentiates the entrance from the exit and vice versa.
