Earth Air Tunnel

이 그림은 안정적인 지하 온도를 활용하여 일년 내내 실내 공기 조건을 조절하는 수동 냉난방 시스템인 Earth Air Tunnel의 개념을 설명합니다.
Earth Air Tunnel의 작동 원리:
이 시스템은 공기 유입구, 지하 터널(최소 2m 깊이), 건물로 통하는 공기 배출구로 구성됩니다. 지구는 비교적 일정한 온도를 유지하여 집에 들어오기 전에 유입되는 공기를 조절하는 데 도움이 됩니다.
1. 여름(냉각 효과)
- 외부 온도: 35°C(뜨거운 공기가 들어옴).
- 지하 터널 온도: 약 25°C.
- 실내 온도: 25°C(냉각된 공기가 집에 들어옴).
프로세스:
- 공기 유입구를 통해 뜨거운 공기가 유입됩니다.
- 지하 터널을 통과할 때 더 차가운 지구가 공기에서 열을 흡수하여 온도를 약 25°C로 낮춥니다.
- 이 더 차가운 공기가 집에 들어와 편안한 실내 온도를 유지합니다.
결과: 이 시스템은 에어컨 없이도 자연스럽게 집을 시원하게 합니다.
2. 겨울(난방 효과)
- 실외 온도: 6°C(차가운 공기가 들어옴).
- 지하 터널 온도: 약 16°C.
- 실내 온도: 16°C(따뜻한 공기가 집으로 들어옴).
프로세스:
- 차가운 공기는 공기 유입구를 통해 유입됩니다.
- 지하 터널을 통과하면서 따뜻한 지구에서 열을 흡수하여 온도를 약 16°C로 올립니다.
- 이렇게 예열된 공기가 집으로 들어와 실내 온도를 편안하게 유지하는 데 도움이 됩니다.
결과: 이 시스템은 전기 난방 없이도 자연스럽게 집을 덥힙니다.
Earth Air Tunnel 시스템의 이점:
✅ 에너지 효율성: 지구의 자연적인 열적 특성을 활용하여 HVAC 시스템의 필요성을 줄입니다.
✅ 지속 가능성: 수동적 기후 제어에 의존하여 탄소 발자국을 줄입니다.
✅ 비용 절감: 난방 및 냉방에 필요한 전기 및 연료 소비를 줄입니다.
✅ 편안한 실내 기후: 일년 내내 안정적인 온도를 유지합니다.

This illustration explains the concept of an Earth Air Tunnel, a passive cooling and heating system that utilizes the stable underground temperature to regulate indoor air conditions throughout the year.

How the Earth Air Tunnel Works:

The system consists of an air inlet, an underground tunnel (at least 2 meters deep), and an air outlet into the building. The earth maintains a relatively constant temperature, which helps moderate incoming air before it enters the house.

1. In Summer (Cooling Effect)

- Outside Temperature: 35°C (hot air enters).

- Underground Tunnel Temperature: Around 25°C.

- Indoor Temperature: 25°C (cooled air enters the home).

Process:

- Hot air is drawn in through the air inlet.

- As it passes through the underground tunnel, the cooler earth absorbs heat from the air, reducing its temperature to about 25°C.

- This cooler air then enters the house, maintaining a comfortable indoor temperature.

Result: The system naturally cools the home without the need for air conditioning.

2. In Winter (Heating Effect)

- Outside Temperature: 6°C (cold air enters).

- Underground Tunnel Temperature: Around 16°C.

- Indoor Temperature: 16°C (warmed air enters the home).

Process:

- Cold air is drawn in through the air inlet.

- As it travels through the underground tunnel, it absorbs heat from the warmer earth, raising its temperature to around 16°C.

- This pre-warmed air then enters the house, helping to maintain a comfortable indoor temperature.

Result: The system naturally heats the home without the need for electrical heating.

Benefits of the Earth Air Tunnel System:

Energy Efficiency: Uses natural thermal properties of the earth, reducing the need for HVAC systems.

Sustainability: Lowers carbon footprint by relying on passive climate control.

Cost Savings: Reduces electricity and fuel consumption for heating and cooling.

Comfortable Indoor Climate: Maintains stable temperatures year-round.
