1 The BallTech ® System Energy saving opportunity for water-cooled chillers

2 The efficiency of water cooled condensers deteriorates over time due to tubes fouling. The efficiency of water cooled condensers deteriorates over time due to tubes fouling. Fouling is recognised as an unavoidable performance impediment by chiller manufacturers and is allowed as part of their design spec. described as “fouling factor”. Fouling is recognised as an unavoidable performance impediment by chiller manufacturers and is allowed as part of their design spec. described as “fouling factor”. This deterioration in condenser efficiency adversely affects the chiller C.O.P.(Co-efficient of performance) This deterioration in condenser efficiency adversely affects the chiller C.O.P.(Co-efficient of performance) A deterioration of the chiller C.O.P results in an unnecessary increase in energy consumption. A deterioration of the chiller C.O.P results in an unnecessary increase in energy consumption.

3 Chemical treatment combined with annual mechanical cleaning can only control the fouling but cannot eliminate it. Chemical treatment combined with annual mechanical cleaning can only control the fouling but cannot eliminate it. Maintaining the condenser efficiency within “acceptable” limits will always lead to dissipation of energy in excess of 10%. Maintaining the condenser efficiency within “acceptable” limits will always lead to dissipation of energy in excess of 10%.
