Alev odasının içinde deneysel ve nümerik olarak elde edilen genel sıcaklık değerleri %12-%16 kadar farklıdır, pencere açıklığındaki sıcaklık değeri %16-%24 arasında daha az tahmin edilmiş ve model içindeki ısı yalıtımı ve son kat kaplama yüzeyi yanındaki sıcaklıkların her ikisi de termoka- pıllarla ölçülen sıcaklıklarından %22 fazla ve (T17, T21 veT19) termokapıllarda ölçülen sıcaklıklardan %18 az tahmin edil- miştir. Cephe ısı yalıtım sisteminin içindeki sıcaklık değerleri deneysel verileri aşmamış ve ortalama sıcaklık sapması de- ğerleri %16’ya eşit olmuştur. 6.
