반사형단열재 열적특성을 통한 효율적인 설치방법에 대한 고찰

The Study on Efficient Methods of Installation through Thermal Features of Reflective Insulators

It was found that the 20mm reflective insulator had more excellent insulation than 500mm styrofoam if radiant heat is discharged to the outside well. However, in case that radiant heat of a reflective insulator is prevented from being discharged to the outside or radiant heat is discharged only partially by making a hole, the 20mm reflective insulator or the aluminum thin film showed lower efficacy of insulation than 50mm styrofoam. But the case that partial radiant heat is discharged into the outside by making a hole rather than sealing radiant heat narrowed the difference. As shown in the above results, it is judged that when installing a reflective insulator, the environment for installation shall be created by considering its thermal features. Therefore, it is judged that a system that can discharge radiant heat into the outside through an air vent etc. in order to achieve a goal that the performance of insulation can be improved even by convenience of constructability and thin thickness that are advantages of a reflective insulator.
