摘要

The air flow and temperature distribution inside household refrigerators/freezers (HRF) for various types of thermal insulation as well as the air supply vents were studied to obtain the optimum design for energy saving vs. temperature uniformity by using the FLOVENT, one of the commercial CFD packages. This paper focuses on a popular type of HRFs which inner volume is about 450 liters. From simulation result, the types of thermal insulation did not significantly affect the airflow distribution, but dominated the transmissible thermal leakage. As vacuum insulation panels (VIP) were applied, the energy saving would be improved over 16% from the result of simulation and experiment. Although the average temperature would be crept little highly as using the multiple supply air vents compared to the simple pattern, and the air speed at vents would be also slow down, the uniformity of air temperature could be improved. Another benefit was that the temperature variation inside cabinet would be kept below 5℃ near the door shelves. The design by using the VIP insulation and multiple air supply vents will attain the optimum for the energy saving and uniformity of air temperature.
