  4. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    An open system combined with energy recovery ventilation can be nearly as efficient (80-95%) as a closed loop, and ensures that entering fresh air is filtered and tempered. Combination system: This can be constructed with dampers that allow either closed or open operation, depending on fresh air ventilation requirements.
