Calculation of System Refrigerant Charge (kg)
The system refrigerant charge can be calculated using the following equation:
SR = LR + IR + OR
Where:
SR
=
Total System Refrigerant Charge (kg)
LR
=
Total Liquid Line Refrigerant Charge. (As calculated from above)
IR
=
Indoor Unit Refrigerant Charge.
OR
=
Outdoor Unit Refrigerant Charge.
Example
Indoor Unit Model Ref. = SC12D023-X200-0
Outdoor Unit Model Ref = CR50 Condenser
Interconnecting Pipework = 10 metres
From the Refrigerant Pipe Sizing Guide, the
liquid line size given for pipework length of 10
metres is:0.09kg/m
SR
= LR + IR + OR
LR = L x m
Where:
LR
= 0.9 kg. (As calculated from above)
IR
= 2.9 kg
OR
= 4.9 kg
SR = 0.9+ 2.9 + 4.9
Calculation of Liquid Line Refrigerant Charge (kg)
The liquid line refrigerant charge can be calculated using the following equation:
LR = L x m
Where:
LR
=
Total Liquid Line Refrigerant charge (kg)
L
=
Length of Interconnecting pipework (metres)
m
=
Liquid Line Refrigerant charge / metre. Refer to Liquid Line
Refrigerant Charge (kg/m), above.
Where:
L
=
10 metres
m
=
0.09 kg/m (Liquid
/LQH6L]H ´
LR
=
10 x 0.09 = 0.9kg
System Refrigerant Charge
Therefore
System Refrigerant
Charge
= 8.7kg / Circuit
