Chilled Water Coil

A chilled water coil is a type of heat exchanger that uses a refrigerant to cool down a liquid or gas. It is often used in air conditioning systems, where it is used to cool air by passing it through a coil of chilled water. The coil is usually made of copper or aluminum and contains a series of tubes that are filled with a refrigerant. The refrigerant absorbs the heat from the air as it passes through the coil, and then releases it to the outside environment. The chilled water coil is an efficient way to cool air, as it requires less energy than other cooling methods. Additionally, it can be used to cool other liquids or gases, such as water or oil.
