Quantity of R410A in 1/2 in OD liquid line: (area) x (length in ft) x (density): 0.0010554 (ft2) x L (ft) x 61.0 (lbm/ft3)

Density of liquid R410A at 40.6°C (105°F) and 260 psig: 0.98 g/cm3 (61.0 lbm/ft3 ) Cross sectional area for 1/2 in OD pipe is 0.0010554 ft2.

Liquid line charge for 1/2 in OD ACR copper tube: 0.095 kg/m (0.0644 lb/ft).

Cross sectional area for 5/8 in OD pipe is 0.001619 ft2.

Quantity of R410A in 5/8 in OD liquid line: (area) x (length in ft) x (density): 0.001619 (ft2) x L (ft) x 61.0 (lbm/ft3).

Liquid line charge for 5/8 in OD ACR copper tube: 0.146 kg/m (0.099 lb/ft).

Example:

Calculate the total R410A charge for an FCB5 condenser with 25 ft of 1/2 in OD liquid piping. Minimum outdoor design temperature is -28.9°C (-20°F).

Note: Imperial units are used in this example.

Total R410A charge: 3.5 + 4.9 + 13.6 + (25*0.0644) = 23.6 lb.
