Hydropath - Single-Pass Sea Water Cooling System
An alternative to cooling towers in the use of single-pass sea water cooling, where sea water is pumped through a heat exchanger, before being returned to the sea. This has the advantage of not leading to a heghten concentration level of scaling in the water, which in turn leads to scaling. However, these systems tend to suffer from problematic biofuling on the heat exchanger surfaces.
Government City Hall, Hong Kong
The cooling system in this government building was sufferning continualy efficiency reduction due the the biofouling on the heat exchanger blocking heat transfer and impeding its operation. After monitoring the temperature, flow rate and power consumption (withoutHydroFLOW®) for a year, a unit was installed and the parameters monitored.
It was found that while the efficiency of the unprotected system gradually dcreaased, when protected byHydroFLOW® the efficiency of the heat exchanger actually actually increased, leading to huge savings in energy and electricity costs.
