A novel design of dehumidifier system in underground pumped storage power station

The heavy water condensation problem has led to safety concern for the workers and electrical facilities in underground pumped storage power station. As current dehumidification scheme, heat humidity load are all removed through air conditioning unit, which high energy consumption low efficiency. a large amount of moisture comes from external fresh air, this study, we set system ventilation tunnel. By using inlet channel lighten wet load, parameters processed as far possible front supply, so achieve purpose saving operation. In numerical modelling was used simulate control scheme environment. Compared with traditional method, two new schemes can take about 1/3 main workshop, efficiency is improved. Therefore, study expected be promising tool reducing workshops.
