Chilled water fan coil units are a type of heating and cooling system that is often used in commercial and industrial buildings. These units are designed to provide efficient and reliable temperature control. They are typically used in applications where space is limited, such as offices, restaurants, and retail stores. Chilled water fan coil units consist of a fan, coil, and chilled water source. The fan draws in air from the space and passes it over the chilled water coil. This cools the air, which is then circulated back into the space. The chilled water is typically provided by a central air conditioning system. Chilled water fan coil units are a cost-effective and energy-efficient way to provide temperature control in a variety of applications. They are also relatively easy to install and maintain, making them a popular choice for many businesses.
