In the heating, ventilation, and air conditioning (HVAC) industry, a chiller is an essential piece of equipment used to produce cold water or refrigerant-based cooling solutions. A chiller basically works by absorbing heat from indoor spaces and transferring that heat externally using a circulation loop. This process allows building managers to maintain comfortable internal settings while also reducing energy costs associated with a commercial facility’s HVAC system. Despite its relatively straightforward design, there are a variety of chillers available on the market today, each specialized to meet the needs of different HVAC applications.
