Abstract
The present study has been carried out to reduce the heat loss from a refrigerator by numerical heat transfer analysis and temperature measurement experiment for the verification of heat transfer analysis result. To perform this purpose, two dimensional heat transfer analysis and measurement of temperature on the surface of freezer for the horizontal cross sectional plane of a refrigerator has been accomplished. From the present study, it could be seen that the steel support in the mullion near gasket region has a heat transfer characteristics which transfer outside heat well from the high temperature hotline and outside air to the inner refrigerator. The effect of removing steel support on the reducing heat loss of a refrigerator was 24.8% and removing steel support might introduce significant improvement of refrigerator heat loss.
