2.What Are Water Cooled Chiller Systems
An alternative to air-cooled systems and rooftop units, water cooled chiller systems are typically used for industrial and commercial applications for their significant energy savings benefits, and to aid companies in their attempts in reducing carbon emissions.
(1)How Do They Differ From Air-Cooled Systems?
Though water and air cooled systems share many components in common - evaporator, condenser, compressor, expansion valve - unlike air-cooled systems, which disperse heat via an air-cooled condenser coil, water cooled chiller systems use water to absorb heat, dispersing it into the air through a cooling tower. It is this component that gives water cooled systems an efficiency advantage over air-cooled and rooftop systems, from 10-100% depending on the setup.
(2)Why Are They So Much More Efficient?
Water is more energy dense than air, providing more efficient cooling than traditional air-cooled options. However these systems come with one main drawback: A higher equipment cost. They are typically used in locations larger than 200,000 square feet, where cooling needs will quickly offset the added cost of equipment. Other applications include industrial use, such as the cooling of plastics and metals, and the cooling of small and large multi-storied structures like universities, hospitals, and large office buildings, as the systems don't require ducts to push air through multiple stories. With system sizes ranging from 20 tons to several thousand, applications are wide and varied.
