Examples of refrigerant charge calculation
Example 1
Receiver
Standing charge
2.4 kg
PHE Gas cooler
Standing charge
0.21 kg
Evaporator Volume 2 dm
3
Calculated from first graph
0.9 kg
Pipe length 8m x K65 3/8”
Calculated from second graph
0.4 kg
Pump
down
(from
evaporator)
Receiver / Evap
≤
7.2 kg
3.3 kg
Total System Charge
Receiver / Gas Cooler / Liquid line/ Evap
≤
7.2kg
3.9 kg
Is charge >4kg (min charge)?
Charge < 4 kg
3.9 kg
Total refrigerant to charge is 4kg.
Example 2
Receiver
Standing charge
2.4 kg
PHE Gas cooler
Standing charge
0.21 kg
Evaporator Volume 12 dm
3
Calculated from first graph
5.2 kg
Pipe length 8m x K65 3/8”
Calculated from second graph
0.4 kg
Pump
down
(from
evaporator)
Receiver / Evap
≤
7.2 kg
7.6 kg
Total System Charge
Receiver / Gas Cooler / Liquid line/ Evap
≤
7.2kg
8.21 kg
Is charge >4kg (min charge)?
Charge >4 kg
8.2 kg
Configuration not permitted. In pump-down condition the refrigerant inside the receiver
exceed the max quantity (7,2kg)
Don’t
overfeed the unit with excessive charge to avoid compressor damaged.
