Description

The HCC is a cooling device that allows the mixing of hot condensate with a lower temperature condensate, avoiding hammering . Condensate discharge from higher pressure lines (drip points, for example) are often connected to a low pressure condensate lines with lower temperature. This sudden pressure drop will convert the sensible heat difference between the two fluid conditions into latent heat generating flash steam. Flash steam has a much bigger volume than condensate and when mixed with the cold condensate it will cool suddenly, imploding and cause hammering (noises and vibrations). The HCC avoids this phenomenon since it slowly cools down the hot condensate which circulates inside a coil surrounded by cold condensate which circulates based on the thermo-siphon physical laws.
