A water cooled chiller is a type of cooling system that uses water to transfer heat away from a process or space. This type of chiller works by circulating a coolant, usually water, through a heat exchanger. The heat exchanger absorbs the heat from the process or space and transfers it to the water, which is then cooled by an external source such as a cooling tower. The cooled water is then circulated back to the heat exchanger, where it absorbs more heat and the cycle continues. Water cooled chillers are commonly used in industrial and commercial applications to maintain a comfortable temperature in a space or to cool machinery and equipment. They are also used in residential applications to cool swimming pools and hot tubs. Water cooled chillers are efficient and cost-effective, making them a popular choice for many applications.
