This chart assumes a minimum -20 Ambient
Unit Info:
Refrigerant Type:
___________________________
Evaporator Temp:
___________________________
1. Number of Cond. Passages/Size:
___________________________
2. Length of cond. Coil (Feet):
___________________________
3. Number/Size of cond. Return Bends:
___________________________
4. Take No. of passes from #1 x #2:
5. Take Number of return bends (#3)
times correct multiplier from table 1:
6. Add #4 and #5 (Total Condenser tubing
length):
7. Find the correct multiplier for -20
ambient and the evap temp from
table 1:
8. Multiply #6 x #7. This is the 100%
Flooding charge.
9. Find percentage for -20 ambient and
evap temp in table 2.
10.Take #8 times #9. This is the total
flooding charge required for the unit.
11. If above a 70deg. Ambient, clear the
sightglass and add the amount in #10.
12. If below 70deg ambient,charge to
a clear sight glass, and find the
corresponding % to flood the condenser
for the current ambient from table 2.
13. Take #9-#12
