Buzdolaplarında şişirici malzemenin ısı iletim katsayısı ve yalıtım kalınlığı üzerindeki etkilerinin araştırılması

As energy efficiency and sustainability become more important with each passing day, the expectations of the materials used for refrigerator insulation have increased. Polyurethane is one of the most common insulation materials today. The choice of blowing agent is a significant subject which is focused on polyurethane to increase the thermal insulation. The blowing agent is among important factors on the total heat transfer coefficient and insulation performance because of its effect on the air additive rate in the polyurethane foam. In this study; the thermal design of a refrigerator and the effect of the blowing agents in the polyurethane on this design were investigated by the computational fluid dynamics. The blowing agents investigated in this study are pentane and LBA materials.
