Introduction to Chiller Unit
A chiller unit is a refrigeration system that removes heat from a liquid via a vapor – compression or absorption refrigeration cycle. This cooled liquid is then circulated through a heat exchanger to cool equipment or air in a building. Chiller units are widely used in various industries such as manufacturing, data centers, hospitals, and commercial buildings to maintain a stable and comfortable temperature environment. They play a crucial role in ensuring the proper operation of equipment and the well – being of occupants. Chiller Unit
