The formula to calculate the Insulation Efficiency (Eins) is:
\[ Eins = \frac{dT}{q} \]
Where:
Insulation efficiency measures how effectively an insulation material reduces heat transfer. It is calculated by dividing the temperature difference across the insulation by the heat flux through it. High insulation efficiency indicates better performance in preventing heat loss or gain.
Let's say the temperature difference (dT) is 30 K, and the heat flux (q) is 5 W/m². Using the formula:
\[ Eins = \frac{30}{5} = 6 \, \text{K-m²/W} \]
So, the insulation efficiency (Eins) is 6 K-m²/W.
