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)
