Hydrothermal energy

The hydrothermal energy system is a system that recovers the surface water and river water of seawater directly or by a heat pump and uses it for cooling and hot water required for buildings.
This system released the load of the building as a heat source when cooling and supplies heat to the room by receiving raw water heat from the heat source when heating.

Advantage of E-gen’s Hydrothermal energy
The first company in Korea to have construction performance of hydrothermal energy. water treatment system and know-how it had accumulated over the years.

- Construction of the world’s largest Hydrothermal energy system

※ The world’s largest single scale
※ It is in the spotlight as an exemplary site for the first use cases of hydrothermal energy in Korea

 - solving heating problems in winter

Construction case : Lotte world tower

Composition of Cooling&Heating system : Ice thermal storage system (10,000 USRt), Geothermal system (3,000 USRt) and Water thermal storage system using(5,000 USRt)

Cooling&Heating systems Peak Load Remark
Thermal Storage system ICE 10,000 USRt 냉방
Water (hydrothermal) 5,000 USRt Cooling&Heating
Renewable energy system Geothermal 3,000 USRt Cooling&Heating
Common Turbo refrigerator 1,800 USRt Cooling
Total 19,800 USRt
Effect of applying hydrothermal energy
Energy saving 15% reduction in cooling energy consumption,
50% reduction in heating energy consumption
Reduction in operating cost using midnight electricity - About 1.4 billion won in cost reduction compared to absorption chiller
Building area and load reduction - Reduced area and building load by reducing the installation of 6 cooling towers
