文摘
Avoiding specular reflection is essential to achieve quantitative IR measurements. Single glazing, IGU’s without low-e and IGU’s with low-e coating are distinguishable. Cloudy, windless conditions and a temperature difference of 15 °C are required. An exact estimation of the thermal resistance is not possible with IRT. Well-estimated internal and external CHTC’s and ambient temperatures are necessary.
