A chilled water unit is a type of cooling system that uses water as a medium to cool down a space. This type of system is often used in commercial and industrial settings to provide a reliable source of cooling for large areas. The unit works by using a compressor to draw in air from the space, which is then cooled by passing it through a series of coils filled with chilled water. The cooled air is then circulated back into the space, providing a comfortable environment. The chilled water unit is an efficient and cost-effective way to cool large areas, as it requires less energy than traditional air conditioning systems. Additionally, it can be used to provide a consistent temperature throughout the space, making it ideal for applications such as server rooms and warehouses.
