Water Chiller Unit: Helpful Buying Guide from TopChiller

1. What is a water chiller unit?

Water Chiller Units are used in a variety of industrial applications where chilled water or liquid are circulated through process equipment.

Commonly used to cool product process or machinery, water chiller units are used in a multitude of different applications including injection molding, machine tool, and die-cutting, food and beverage, chemicals, lasers, machine tooling, semiconductors, and more other applications.

2. Why did we need to install a water chiller unit?

Water chiller units can be used for a variety of industrial applications for providing a steady cooling source.

The purpose of using a water chiller unit is to move heat from one location (usually process equipment or product) to another place (usually the air outside the manufacturing facility).

It is very common to use water or a water/glycol solution to transfer the heat to and from the water chiller which may require the process chiller to have a reservoir and pumping system.

Regardless of your industry and process, making sure that you have sufficient water cooling source is critical to productivity and cost savings.

A water chiller unit is a necessary water cooling system for industrial applications and laboratory testing.

3. How does a water chiller unit work?

As we know a water chiller unit is a water cooling refrigeration machine.

In most process cooling applications, a pumping system circulates cool water or a water/glycol solution from a water chiller unit to the process.

Water chiller unit can cool fluid removes heat from the process and the warm fluid returns to the chiller. The process water is the means by which heat transfers from the process to the chiller.

Process chillers contain a chemical compound, called a refrigerant.

There are many types of refrigerants and applications depending on the temperatures required but they all work on the basic principle of compression and phase-change of the refrigerant from a liquid to a gas and back to a liquid.

This process of heating and cooling the refrigerant and changing it from a gas to a liquid and back again is the refrigeration cycle.

The working principle of a water chiller unit as below:

The refrigeration cycle starts with a low-pressure liquid/gas mix entering the evaporator.

In the evaporator, heat from the process water or water/glycol solution boils the refrigerant, which changes it from a low-pressure liquid to a low-pressure gas.

The low-pressure gas enters the compressor where it is compressed to high-pressure gas.

The high-pressure gas enters the condenser where ambient air or condenser water removes heat to cool it to a high-pressure liquid.

The high-pressure liquid travels to the expansion valve, which controls how much liquid refrigerant enters the evaporator, thereby beginning the refrigeration cycle again.

There are two types of condensers used in water chiller units; air-cooled chillers and water-cooled chillers.

An air-cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid.

It can be located inside the chiller or can be remotely located outside, but ultimately it rejects the heat from the chiller to the air.

But in a water-cooled condenser, water from a cooling tower cools and condenses the refrigerant.

Different condenser types make the biggest difference between the air-cooled chiller and water-cooled chiller.

4. What are the Main Components of the Water Chiller Unit?

The Water Chiller Unit provides cooling to small applications as well as larger applications.

To provide efficient cooling to the application. The Water Chiller Unit uses different components and equipment.

Compressor

The compressor is an important piece of equipment. A compressor in the Water Chiller Unit creates pressure to move the refrigerant.

There are different types of compressors and every compressor has different pros and cons.

The compressor is always located between the evaporator and condenser. The compressor has an electrical motor.

The motor in the compressor is used as a driving force. The motor can be attached internally or externally.

The compressor is sometimes noisy. So it is better to put on some sound-absorbing equipment while working near a Water Chiller Unit or keep it away from the range.

Condenser

Right after the compressor and before the expansion valve the condenser is located.

The task of the condenser is to remove the heat from the refrigerant. The heat that the condenser removes is picked by the evaporator.

There are two types of the condenser

Water-cooled condenser:  the water-cooled condenser cycles the water between the condenser and the cooling tower.

The hot refrigerant which travels to the condenser through the compressor and transfers its heat in water and later removes from the application,

Air-cooled condenser: The condenser in an air-cooled condenser does not use the cooling tower, it removes air through pipes of the condenser.

The expansion valve

The location of the expansion valve is well-positioned, It is located between the evaporator and condenser.

The expansion valve expands the refrigerant. Expanding increases the volume, which helps it to acquire more unwanted heat from the evaporator.

Although there are many different types of expansion valves. The widely used is the thermal expansion valve.

Control unit

The control unit controls its all activities and It is located on the top of the Water Chiller Unit.

It indicates its performance the rate of flow. It also alarms when identifying any unwanted activity either in the system or in the application.

This helps in detecting the problem. For safety insurance, the Water Chiller Unit shut down by itself.

The control unit also shows the voltage of electricity.

Evaporator

The evaporator is placed between the compressor and the expansion valve.

The main task of the evaporator is that it collects unwanted heat from the application and sends this to the refrigerant to remove it from the cooling towers.

The temperature of water decreases and it cools down as the heat travels to the refrigerant.  The cool water is circulated in application to provide cooling.

The evaporator of the Water Chiller Unit is a very important component.

5. Is the Water Chiller Unit cost-efficient?

  • The Water Chiller Unit is a very cost-friendly system. Due to its nature of reusing and recycling the water, it saves a lot of water.
  • The cost of maintenance is also reasonable because its cost-efficient nature consumes less electrical power as compared to the other cooling alternatives.
  • However, you have to keep your Water Chiller Unit maintained for better efficiency.
  • The essential component such as compressor, evaporator, and expansion valve are easy to change and replace.
  • The cost of this equipment is also normal.
  • An expert suggests that the Water Chiller Unit saves up to 25% of the electricity bills as compared to other individual and small systems.
  • It has a compact design that saves your space by fitting in every condition. You can also include an auto shut down system in it.
  • The Water Chiller Unit shuts down when the power is unstable.
  • The auto-shutdown prevent it from being damaged and also saves application
  • This will save you extra expenses.
  • It only consumes electricity when it is loaded.

6. What is the Working Principle of the Water Chiller Unit?

Different elements of the Water Chiller Unit work accordingly to provide cooling efficiency.

There are some basic principles upon which it is processed.

Phase Change

The liquid always undergoes a phase that is called a phase change. During this phase of refrigeration, the liquid changes into gas when it is heated.

When the gas is supercooled again and the gas condenses back to liquid.

Heat Flow

Heat flow is the second phase after the phase change.

In this phase, the heat energy flows from an area of a high concentration to an area of a lower concentration.

Boiling Point

 The boiling point is the third and lasts working principle of the Water Chiller Unit. The decrease in the pressure of liquid also decreases its boiling point.

The increasing pressure increases its boiling point.

The Working Process of the Water Chiller Unit

The Water Chiller Unit has four basic components; Evaporator, compressor, condenser, and expansion valve unit.

These components work together to perform the task of the Water Chiller Unit.

When the low-pressure refrigerant enters the evaporator then the process starts.

In the evaporator, the refrigerant is heated and it undergoes the phase change. The refrigerant changes into a gas.

The refrigerant is gaseous state travels to the compressor, which increases the pressure of the refrigerant.

The refrigerant leaves the compressor with high pressure to the condenser. The condenser rejects the heat with help of air or a cooling tower.

The condenser condenses it into the high-pressure liquid. After the leaven condenser the condensed refrigerant journeys to the expansion valve unit.

The expansion valve unit limits the flow of refrigerant in the Water Chiller Unit.

This lowers the pressure of refrigerant or liquid. Then the whole process repeats.

The Water Chiller Unit works effectively and efficiently in a free environment and open environments.

It needs a suitable environment with no moisture and zero external forces that affect its working, such as rain.

It needs a flow of current that is stable because a certain variation in its flowing current can lead to damage and cause an error in the application process.

  • The cool water temperature you need for your application.

You can also size the it with help of mathematics. You need to compare the gallons of cooled water you need from your Water Chiller Unit per minute.

If you need 5 gallons per minute and your Unit provides 3 gallons of water per minute, it means its size is not efficient.

The Water Chiller Unit is big so you have to put it in a comfortable space.

The size also depends on the power supply you get.

If you have enough space compare to its size then opt for it.

If space is missing, you need to create space first.

If the size of the Water Chiller Unit is smaller than the voltage you get then it will be impossible to operate it

The Ideal Size:  To find the most ideal and perfect Water Chiller Unit for your application you need to, multiply the cooling capacity by 20%.

After the multiplication round of the number to the nearest whole number. So it will be the ideal size of the Water Chiller Unit.

  • Formula: The ideal size in tons= Tons x 1.2
