Uf = 5,95 W/m2K
Uf = 4,57 W/m2K
En este informe se detemina el coeficiente de transmisión térmica (Uf) mediante dos
métodos de cálculo diferentes:
A) Aplicando la norma EN ISO 10077-2:2003, y usando el software “BISCO” de la
empresa Physibel.
1
B) Aplicando un método própio, “know-how” de Technoform, dónde se usa el
software “RADCON”- también propiedad de Physibel - y el valor final equivale
aproximadamente al resultado en el test de cálculo de nuestra HOT-BOX (La
diferencia es de un 5%) según norma ISO/FDIS 12567:2000.
