U (daban-daban) irin lantarki dumama bututun zabi bisa:
1, ciki size na tank, tsawon × fadi × tsayi, ruwa tsayi.
2, Tsarin zafin jiki, farawa zafin jiki, ƙarshen zafin jiki.
Tsarin yana buƙatar lokacin dumama ko sanyaya (h).
Canjin zafi (dumama, sanyaya):
Q = V × C × r × β (t2-t1) / T (kilocalories)
V: mafita girman (lita)
C: mafita mafita (kcal / lita × C)
r: rabo (kg / lita)
t1: farkon zafin jiki na mafita
t2: Maganin ƙarshen zafin jiki
β: zafi hasara factor (dauki 1.10-1.30)
Q ne mai kyau, zafi da ake bukata don dumama
Q ne mummunan darajar, to, yawan sanyi da ake buƙata don sanyaya
T: dumama ko pre-sanyi lokaci h (hours)
lantarki zafi equivalent (electrolytic zafi):
Q = 0,864 × I × V (Kcal / h)
I: Total halin yanzu A V: Slot ƙarfin lantarki V
Tabbatar da zafi musayar yankin S:
S = Q / K × ΔT × t
Q: Canjin zafi (kilocalories)
K: zafi watsa lamba kcal / m2 × hr × C (duba zafi watsa lamba tebur V)
V: mafita girman (lita)
ΔT: Matsakaicin bambancin zafin jiki
t: saita dumama (sanyaya) lokaci (h)
