New and renewable energy

The new and renewable energy sector is divided into terrestrial heat, solar power, Fuel cell, and EMS. Our businesses in various areas include buildings, plants, apartments, roads, and tunnels, for the production of new and renewable energy, reduction of energy consumption, and effective integrated management.

New and renewable energy : 지열,태양광,EMS,Fuel cell
  • Terrestrial heat Open type Building-integrated type
  • Solar power Stand-alone type Grid-connected type Building-integrated type
  • Fuel cell For building
여름 : 외부온도 35℃ , 연중 15±5℃ 일때 실내열을 흡수하여 지중으로 방출
겨울 : 외부온도 -10℃ , 연중 15±5℃ 일때 지중열을 흡수하여 실내로 공급

Terrestrial heat-based heating/air-conditioning system

  • Environmentally friendly system that does not use fossil fuels (only electrical energy)
  • Using a subterranean heat source (15±5°C) that maintains a constant temperature throughout the year and a heat pump with high efficiency
  • Management of heating/air conditioning and hot water supply at the same time with a single system
  • System efficiency of more than 300%

Analysis of the strengths and opportunities of geothermal systems

지열 시스탬의 강점과 기회분석 테이블
Strength
  • High efficiency (over COP 3.0) COP : coefficient of performance
    COP = Production energy / Consumption energy
    COP 3.0 = Efficiency 300%
Opportunity
  • Application of a system unaffected by external temperature and moisture conditions
  • No need to store or manage inflammables, previous energy sources
  • Uses electricity unaffected by progressive tax as consumption energy
  • Uses a system that decreases C02 emissions

Open-type method to prevent shot cut

숏컷방지 개방형 공법 구조: 공급관, 환수관, 지하수 환수관, 심장펌프, 내부케이싱, 충진재, 유공관, 지하수 수출관으로 되어있습니다.
  • Features of the Open-type method
    • - Performance : about 100kW/hole (based on 500m)
    • - Fill the space between the inner pipe and the hall with filler
    • - Install the perforated drainpipe to the floor
    • - Prevent sinking and improve heat exchange rate
    • - Applicable to large fields with high-capacity, high-efficiency way

Photovoltaics System

  • A new and renewable energy system which produces electricity using sunlight
  • Its major components are modules composed of solar cells, inverters, and monitoring facilities

Features of solar power

태양광의 특징
Advantages
  • Clean, infinite energy source
  • Power generation available anywhere needed
  • Easy maintenance and possibility of unmanned system
  • Long life span (20 years)
  • Quick response to changes in demand with a short construction period
Disadvantages
  • The amount of electricity produced varies depending on the amount of solar radiation in each area
  • Requires wider installation area due to low energy density
  • Decrease in efficiency due to weather factors
  • Difficulty in applying to urban areas
