Table 71 —Refrigerant to Add for Sub MDC
Table 72 —Refrigerant to Add for Connected Capacity
Calculating the Amount of Refrigerant to Add
R = (HP x RGP) + (LP x RLP) + MM + SM = CC
Legend:
R = Refrigerant (lbs)
HP = Actual length of high pressure at diameter Ø (ft)
RHP = Refrigerant to add per high pressure pipe (lbs/ft) (Table 68)
LP = Actual length of liquid pipes at diameter Ø (ft)
RLP = Refrigerant to add per liquid pipe (lbs/ft) (Table 69)
MM = Refrigerant to add for main MDCs (lbs/ft) (Table 70)
SM = Refrigerant to add for Sub MDCs (lbs/ft) (Table 71)
CC = Refrigerant to add for connecting capacity (lbs/ft) (Table 72)
