Thermal conductivity of insulations approached from a new aspect

摘要: In the literature, several definitions can be found for thermal conductivity; however, many of them are not clearly explained. The easiest explanation is following: property a material to conduct heat. It evaluated primarily in terms Fourier’s Law heat conduction. Nowadays, examination conductivity building materials very important both manufacturers and consumers. Nonetheless real, confusing interpretations regarding exact meaning materials. physics engineering practice, following appellations used as conductivity, conduction coefficient, design declared values conductivities well effective conductivity. this article we would give an overview about correct explanations above-mentioned values. At first measurements four different types expanded polystyrene (EPS, 80, 100, 150, 200) will presented by using Holometrix Lambda 2000 type Heat Flow Meter after drying Venticell 111 laboratory oven changeless mass.
