In a central plant system, there are two types of water piping loops: closed and open. An open loop is from the chiller to the cooling tower. As the water flows through the tower, it is open to the atmosphere. Because of evaporation at the cooling tower, city water is introduced to replace the evaporated […]
Central Plants may utilize plate and frame heat exchangers for “free cooling” or other types of heat transfer. Maintenance of your plate and frame heat exchanger should be part of your scheduled service program. The plate exchanger, shown below, consists of corrugated plates assembled into a frame. The hot fluid flows in one direction in […]
