Room Temperature Control :23±0.3℃

Eco-Friendly Air Conditioning using Geothermy

- Absorbing the fresh air
 - Making its degree stable with geothermal heat
 - Control the air 23℃ in air conditioner
 - Discharging 23℃ air into rooms
 
Merit of Underground Factory
The chart below is the comparison of YUME factory (underground) and grond-factory assumed to have same condition as YUME factory considering the effect on economy and environment. It clearly shows that underground condition brings in large cost reduction of air-conditioning. Even construction cost of underground is 25% higher than ground one, the cost reduction still can cover it.
This system also results in reduction of CO2 emission. So we can say that underground facility is a big merit on our quality and Eco-action.
