Ground Source Heat Pump (IGH-11A, 11B series)

Principle

Ground Source Heat Pump




Ground Source Heat Pump


  • * Product Overview
  • A highly efficient and eco-friendly system where ground heat that maintains
    a constant temperature throughout the year is used for cooling and heating
    using the PE pipe buried underground
  • * Features
  • ① Stable heat source: Temperature of 15°C on average maintained throughout
        the year
    ② Economic Efficiency: Output water at up to 70°C can be obtained by applying
        the highly efficient new refrigerant (COP: 3.7-7.0)
    ③ Minimized machine room space: Enabling better space management and
        utilization
    ④ Simplified system enabling auto control and easy operation
    ⑤ ECO-friendliness: Free of exhaustion gas and pollution
    ⑥ Controllable temperature of the output water, and stable system by applying
        the inverter system
  • * Application
  • ① For buildings with sufficient ground water and surrounding space
        to bury ground heat pipe underground
    ② For places requiring a lot of hot water (such as hotel, public bath), this
        Ground Heat Source Heat Pump can be linked to a Wastewater Source system
    ③ Aquaculture and agriculture requiring cooling and heating
    ④ Any building where cooling/heating or hot/cold water is required
