Summary

In Korea, white plume generated by cooling tower is a one of major social conflicts due to its visual pollution. Various methods have been developed to abate plume generation, such as outdoor air condensing, dry/wet hybrid cooling, membrane method, etc. However when cooling towers operate in cold climate without plume generation, both humidity ration and relative humidity have to be reduced with effective methods. Dehumidification and regeneration using heat pump cycle can be a good technical solution for this since it condense water vapor and then reheat the air with condensation heat and compressor power input. The required energy of a heat pump method is 3 to 4 times less than a direct heating method. For further energy reduction, an outdoor air mixing is introduced before heat pump stage and the power input can be reduced up to 10% compared to a direct heating.
