4. Length of refrigerant pipe and injection rate
The refrigerant in the lengthened part of the refrigerant pipe was not fed before delivery
and needs to feed on the spot.
Calculation method: the supplementary injection rate is calculated according to the specification
of liquid pipe and real length of the refrigerant pipe installed.
Supplementary injection rate on the spot = real length of liquid pipe x injection rate of liquid pipe
Injection rate (kg) = (L1 x 0.115 kg/m) + (L2 x 0.065 kg/m) + (L3 x 0.030 kg/m)
L1: Real total length of liquid pipe *12.7
L2: Real total length of liquid pipe *9.5
L3: Real total length of liquid pipe *6.4
