Increase chiller efficiency
Webimprove chiller efficiency is to increase the heat exchanger’s surface area— add more tubes to the evaporator and/ or condenser. More tubes result in a greater flow area and a lower design fluid velocity. A higher minimum flow is required to maintain sufficient fluid velocity to prevent laminar flow conditions. Laminar operation can lead WebChiller efficiency is especially advantageous where less than full output is required because the cooling load is moderate. In most climates, this may be over 90 percent of the time. …
