Puterea <strong>de</strong> incalzire si racire<br />
Tabelele <strong>de</strong> mai jos prezinta capacitatea<br />
<strong>de</strong> incalzire si racire a zehn<strong>de</strong>r<br />
<strong>ZBN</strong> in functie <strong>de</strong> t corespunzator.<br />
Valorile puterii <strong>de</strong> incalzire au fost<br />
masurate conform standardului EN<br />
14037, rezultatele masuratorilor cu<br />
privire la puterea racire fiind bazate<br />
pe DIN 14240.<br />
Observatie: se obtine un efect pozitiv<br />
asupra capacitatii <strong>de</strong> racire prin<br />
in<strong>de</strong>partarea izolatiei (vezi tabelul).<br />
Aceasta crestere a puterii nu se poate<br />
lua in calcul <strong>de</strong>cat in incaperile in<br />
care tavanul nu este acoperit.<br />
Prin in<strong>de</strong>partarea izolatiei creste in<br />
mod cert puterea <strong>de</strong> incalzire, dar<br />
dar acest lucru are ca rezultat<br />
acumularea caldurii sub tavan.<br />
Capacitate = K · t n<br />
