What Is a Water Cooled Chiller?

A water cooled chiller is a type of refrigeration machines that used to remove heat from a  industrial process by transferring it to water.In fact, Water chillers transfer heat from a space that needs temperature control and transfer it to another space. Therefore, the water chiller is not a means of generating cold, but a means of dissipating heat, and its task is to facilitate the transfer of unwanted and undesirable heat caused by the activity to a place outside the system.

The water cooled chiller need use water to transfer heat away from the industrial process,so a water cooling tower is an essential part for the water-cooled chiller.Water-cooled chillers dissipate heat by circulating water through a separate water cooling tower .The hot water from the chiller is pumped to the cooling tower, where it releases heat to the atmosphere through evaporation. Chilled water is then returned to the chiller for the cooling process.

Components of a Water Cooled Chiller

A water cooled chiller consists of four main parts :

Compressor: The compressor is the heart of the chiller and is responsible for compressing the refrigerant and raising its temperature.

Condenser: The condenser is where the refrigerant releases its heat to the water. It consists of a series of tubes through which the water flows.

Evaporator: The evaporator is where the water absorbs the heat from the industrial process or machine being cooled. It consists of a series of tubes through which the water flows.

Expansion Valve: The expansion valve regulates the flow of refrigerant into the evaporator, allowing it to expand and absorb heat.

How Does A Water Cooled Chiller Work ?

The working principle of a water cooled chiller ,like air cooled chiller,consists of four main parts: compressor, evaporator, a condenser, and expansion valve. When water cooled chiller is turned on, the refrigerant is compressed by the compressor and transformed into a high-pressure, high-temperature gas. The refrigerant then flows through the condenser, where it releases heat to the coolant water. The coolant water is then sent to a cooling tower where it releases the heat into the atmosphere. The refrigerant, now a low-pressure, low-temperature gas, moves through the evaporator, where it absorbs heat from the industrial process or machine, and the cycle repeats.

Advantages and Disadvantages of Water Cooled Chiller

Advantages:

Higher Efficiency: Water cooled chillers are more efficient than air cooled chillers, as water can absorb and transfer heat more efficiently than air. For example, the cooling capacity for 15HP water cooled chiller is about 50KW ,but the cooling capacity for 15HP air cooled chiller just is 45KW ,they are both 15hp chiller .

Less Space: Water cooled chillers take up less space and can be installed not only outdoor indoors but also outdoors,and they are with low noise

Longer Lifespan: Water-cooled chillers have a longer lifespan than air-cooled chillers, as they are less prone to corrosion and damage caused by environmental factors.

Work in high ambient temperature : As water cooled chiller through cooling tower to heat dissipate,so it can work in high ambient temperature above 45℃,but air cooled chiller dissipate heat by air ,so when it work in high ambient temperature ,it may appear high pressure alarm.

Disadvantages:

Higher Cost: Water-cooled chillers are more expensive to install and maintain than air-cooled chillers, as water cooled chiller is with water-cooled condenser,which it require additional components such as cooling towers and water pumps.When users install them, they need purchase more pipes.

Water Usage: Water-cooled chillers require a constant supply of water, which can be a challenge in areas with limited water resources.

Water cooled chillers play an essential role to control the temperature you want in your industrial process. They require a more complicated installation process and a water source, which can be costly. But you are looking a large cooling capacity chiller and high cooling efficient solution for your industrial needs, a water cooled chiller might be an excellent option for your business. Contact US Now!
