Examples of refrigerant charge calculation
Example 1
Receiver
PHE Gas cooler
Evaporator Volume 2 dm
Pipe length 8m x K65 3/8"
Pump
evaporator)
Total System Charge
Is charge >4kg (min charge)?
Total refrigerant to charge is 4kg.
Example 2
Receiver
PHE Gas cooler
Evaporator Volume 12 dm
Pipe length 8m x K65 3/8"
Pump
evaporator)
Total System Charge
Is charge >4kg (min charge)?
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.
