Water Cooled Chiller-An Ultimate FAQ Guide by TopChiller.

What is a Water Cooled Chiller?

A Water Cooled Chiller can be defined as a cooling system that facilitates heat exchange by recirculating water from a cooling tower.

It dissipates heat from the process by absorbing it and then releasing it into the environment. In this way, it functions to decrease the temperature of the industrial process.

It is has a vast area of applications and used to maintain the temperature of industrial machinery during industrial processes.

The chilled water is processed through the equipment, where it absorbs heat, and the warmed water returns to be processed again. This is how the whole refrigerant cycle works.

The heat produced as a necessary by-product needs to be released outside the applications. Cooling towers installed with the chiller play a role in getting rid of this leftover heat.

Water Cooled Chiller provides a highly efficient method that cools and dehumidifies air and significantly dissipates heat from industrial applications forming a closed loop.

What are the Uses of a Water Cooled Chiller?

A Water Cooled Chiller is a reliable source of cooling an industrial environment that is used:

Cool Down the Equipment

Even at extreme temperature conditions, it has an enormous cooling capacity and provides efficient cooling between 180,000 to 18,000,000 BTUs per hour.

It is optimal for large industrial applications to remove excessive heat from the industrial equipment where ordinary air conditioners fail.

Protect from Heat Damages

The Water Cooled Chiller protects your industrial equipment from excessive heat damages.

At extremely high temperatures in the industrial environment, the mechanical devices suffer damages from heat.

Heat accumulates there over time. It reduces the durability of the applications, and ultimately the equipment gets destroyed.

Excessive Cooling With Minimal Expenses 

It efficiently lowers the temperature of the industrial process and is far more effective than the use of many ordinary air conditioners.

This method of cooling is highly energy-efficient. Moreover, it recirculates water within the system, thus, reduces your costs on extensive water supply and electricity consumption.

What are the Major Parts of Water Cooled Chiller?

Water Cooled Chiller consists of various parts; some significant parts are listed below:


The compressor converts the low pressure and temperature refrigerant into high pressure and temperature gas.

It drives the refrigerant around the system by forming a pressure difference. Centrifugal, screw, or scroll compressors are used in it.


The compressed refrigerant traveled through a condenser. Water-cooled shell and tube-type condenser are installed in a Water Cooled Chiller.

A condenser removes heat from the refrigerant and condenses it into liquid.


The refrigerant and fluid interact in the evaporator. The refrigerant goes back to the evaporator, where it absorbs heat from the water.

Shell and tube, copper coil, and plate are commonly used evaporators.

Expansion Valve

The expansion valve manages the amount of refrigerant that passes between the evaporator and condenser.

It changes the flow of refrigerant based on cooling load.


The entire pumping system circulates the water from the chiller to the process that needs to be cooled.


The function of a filter is to capture contaminants and dirt particles that enter the chiller fluid.

How Does a Water Cooled Chiller Work?

The entire process of a Water Cooled Chiller operates under the principle of vapor compression refrigeration cycle.

In the cycle, refrigerant converts from liquid to gas and from gas to liquid through heat exchangers.

The fluid pressure increases and decreases by the compressor and expansion valve, respectively.

The refrigerant cycle starts with the compressor that converts the refrigerant from low-pressure gas to high-pressure gas.

It is then passed to a condenser that acts as a heat exchanger. It transfers heat from the refrigerant to the water.

Consequently, the refrigerant is cooled and condenses into a liquid state.

The liquefied refrigerant with high pressure then passes by expansion valves to reduce the pressure. The low pressured refrigerant interacts with water in the evaporator.

The refrigerant absorbs heat from water in the evaporator and vaporizes. The low-pressure refrigerant gas returns to the condenser, and the cycle repeats.

Water releases unwanted heat to the cooling towers from where it is lost in the environment.

Water circulates again and again through the system and absorbs heat. The recirculating process goes on.

Why Do you Need a Water Cooled Chiller for your Applications?

A machine with 100% efficiency doesn’t exist. Heat is an essential by-product of all industrial processes.

If this heat is not efficiently removed from the process, it may accumulate there over time. This extra heat can cause the premature failure of industrial machinery, equipment shutdown, and reduced production rate.

Therefore, it is necessary to withdraw heat from your industrial process system.

A Water Cooled Chiller is frequently used to avoid the over-accumulation of heat in industrial systems.

It lowers the system’s temperature by recirculating water through the system with minimal loss of water.

What are the Prominent Applications of Water Cooled Chiller?

In industries, chilled water is circulated through the system that needs to be cooled, and heat is dissipated from the system by this means.

A Water Cooled Chiller is utilized to stabilize the temperature of various products and machinery in most of the manufacturing industries, medical and research centers, and many vast areas.

The prominent applications are:

  • Plastic Manufacturing Industry
  • Metal Plating
  • Food and Beverage Production
  • Pharmaceutical Industry
  • Hospitals
  • Tool and Die-Cutting
  • Paper and Cement Industries
  • Chemical Processing
  • Power Generation Stations
  • Metalworking
  • Welding Tools
  • Semiconductors Industries

It is also broadly used in hotels, schools, and even in residential buildings.

What is the Difference Between Operational Cost of Water Cooled Chiller and Air Cooled Chiller?

In a Water Cooled Chiller, the condenser is connected with a cooling tower anduses water as the condensing medium.

In contrast, the air is the condensing medium in air cooled chillers; the condenserdissipates heat from the refrigerant to ambient air.

For air cooled chillers, the refrigerant condensing temperature relies on the ambient dry-bulb temperature.

On the other hand, the Water Cooled Chiller refrigerant condensing temperature relies on the flow rate and condensing water temperature that equals the wet-bulb temperature.

Thus, the operational costs of the latter one relatively lower than the former.

In other words, the condenser that operates at lower pressure has lower functioning costs.

A Water Cooled Chiller is efficient in terms of electricity consumption. Still, its maintenance and initial costs are higher than the air cooled chiller because it needs the installation of a cooling tower and a constant supply of water.

How Proficient is a Water Cooled Chiller?

A Water Cooled Chiller is 20 percent more efficient than an air cooled chiller. It usesa water-cooled shell and tube-type condenser, with an outdoor cooling tower and water circulation pumps that increase its cooling efficiency.

The cooling tower increases its ability to condense water far better than the ambient air. It decreases the energy consumption of the chiller.

The energy consumption of a Water Cooled Chiller is approximately 10 percent that is 60 percent for air cooled chillers. It has a relatively long life.

How to Calculate the Working Efficiency of your Water Cooled Chiller?

The working proficiency of a Water Cooled Chiller can be calculated in terms of the coefficient of performance (COP).

The coefficient of performance is simply a ratio of the refrigerant effect produced by your chiller and the amount of electricity consumed by the chiller.

Both of these values are measured in watts.

For instance, the cooling capacity of your chiller is 2,500kW; it can be measured in terms of BTU that will be, in the case, 8,533,364BTU/h.

If its power consumption demand is 460kW, the energy efficiency ratio or COP will be 5.4.

What is the Accurate Water Temperature for Water Cooled Chiller?

The accurate water temperature for Water Cooled Chiller is usually 4℃ but can range somewhere between 5℃ and 7℃.

It may vary significantly according to the type of application for which the chiller is used.

What are the Refrigerant Types for a Water Cooled Chiller?

These are the following five types of refrigerants according to their chemical make-up:

  1. Saturated hydrocarbon cooling agent
  2. Unsaturated hydrocarbon cooling agent
  3. Freon
  4. Azeotrope refrigerant
  5. Inorganic substance cooling agent

Water Cooled Chiller most commonly uses Freon and R-22 type cooling refrigerants.

The chemical composition of R-22 is difluoro-chloromethane. It is primarily used in industrial and residential air conditioning, catering, and commercial refrigeration systems.

Motor Overload Protectors

Extremely high ambient temperature and unstable voltage damage the water pump motors, compressors, and fan motors.

If the motor keeps on running, it may fall short. Motor overload protection devices shut down the chiller under these conditions and alarm you in case of any malfunctioning.

Water Flow Protectors

The water flow switch regulates the flow of water in the system. It prevents any damage by water leakage and circuit blockage.

Overheat Protector

The refrigeration cycle reduces the temperature of water between 3℃ and 8℃.

In case if the chiller is not working correctly or the ambient temperature is too high, the temperature in the circuit will go on increasing higher and higher. It can damage the circuit as well as equipment.

Overheat protectors alarm in such dangerous conditions.

Emergency Stop Switch

Sometimes, it produces strange noises or vibrations due to irregular voltage, overload, or other reasons.

There is an emergency stop switch to shut down the chiller immediately in case of such an emergency.

Other protection devices are also activated in an emergency to prevent any mechanical failure and ensure the long life of your chiller.
