진공단열재를 적용한 컨테이너의 단열성능 평가에 대한 연구

초록

The thermal insulation performance of a container with a vacuum-insulated panel was numerically investigated herein. The heat loss caused by natural and mixed convection through the container was calculated for various indoor/outdoor air temperatures and outdoor air velocities. The outdoor velocities had a minor influence on the heat loss because of the extremely low thermal conductivity of the vacuum insulated panel. The amount of heat loss was mainly determined using the temperature difference between the indoor and outdoor air. The monthly variations of the total heat loss through the container were evaluate d using the monthly averaged climate data, including the maximum and minimum outdoor temperatures. The results revealed that the container with the vacuum insulated panel exhibited superior thermal insulation performance, as evidenced by the maximum heat loss value of 324.5 W.
