Water-cooled screw chiller
Water-cooled screw chiller systems are especially used for large cooling loads, they have a cooling tower for refrigerant heat dissipation that higher efficiency than air-cooled chillers which use fans for refrigerant heat dissipation.
Water-cooled chillers are more efficient because they condense depending on the ambient temperature bulb temperature, which is lower than the ambient dry bulb temperature.
Normally water-cooled chillers are cheaper and more efficient, with the disadvantage of high water consumption and cost more to install and maintain.
This system has several essential components including:
Condenser cooling pump
process chilled water pump
The difference between Air-cooled chiller and Water-cooled chiller
An air-cooled chiller refers to a chiller system that uses the ambient air surrounding the condensing unit to cool and condense the refrigerant back into a liquid. In other words, the air cooled chillers use fans for chiller's refrigerant dissipate heat.
The most common types of water cooled chillers use water from an external cooling tower to cool the refrigerant in the condenser.They need to install cooling tower and cooling pump for operation. since they require a constant supply of water for cooling, they might not be suitable for locations with water shortages or restrictions.
