벽체 점형 열교 발생 부위의 단열재 두께에 따른 전열량 평가

Abstract

In this study, in order to derive the performance evaluation methodology for thermal breaker required in the field, the effect on the thermal performance of the wall sample was investigated by using an analytical method for an thermal breaking anchor to prevent point-type thermal bridges.BRAccording to the thickness of the insulation material, the type of insulation material, and whether the anchor is insulated, the amount of heat transfer and the point-type thermal transmittance were calculated through heat transfer simulation and the difference was confirmed. For both grades “A” and “B” insulators, the amount of heat transferred was linearly changed according to the change in the thickness of the insulation. When a stainless steel thermal breaking anchor was applied, the point-type thermal transmittance was reduced by half compared to the case where a conventional steel anchor was installed.
