Clean Condensers Conserve Energy

 

1. The current industry practice addresses scale and fouling in condensers in the following ways:
   1. Chemicals : Dosing the water with chemicals to inhibit scaling and fouling.
   2. Blowing down : Reduce the scaling tendency of water by draining “dirty” (high TDS) water and topping up with “clean” water.
   3. Manual Cleaning :Using a rod and brush to manually swab each and every signal condenser tube in order to brush off all scale and fouling formed on the tubes surface.
2. These methods do not eliminate scaling and fouling in condensers completely as evidenced by the need to carry out periodic manual cleaning.
3. The typical energy consumption pattern for the chiller using these methods is shown in Figure 3 below.
