Chilled water systems are used for cooling buildings and industrial processes. They work by circulating chilled water through a network of pipes, absorbing heat from the air or equipment. This process helps maintain comfortable indoor temperatures and improves energy efficiency. The system typically includes components like chillers, pumps, and air handling units. Chillers cool the water, while pumps circulate it throughout the system. Air handling units then distribute the cooled air into the space, ensuring a consistent and comfortable environment for occupants.
