We are globally developing technology to use natural environment because of environmental degradation and energy resource depletion problem. Of these technologies, assessed an efficiency of Cool Tube System to use geothermal heat. Buried pipelines material was STS, and was buried in the underground 4m. Tube System was ventilated using differential pressure of indoor/outdoor by the heat recovery ventilation of the exhaust fan. As a result, Cool Tube System inlet and outlet temperature difference showed approximately 5~15℃, Humidity difference showed approximately 10~25%. In addition, depending on the temperature and humidity of the outdoor, indoor thermal environments were effected more than greater. |
