Calcolatore Carica Refrigerante Gratuito
Calcola la quantità aggiuntiva di gas refrigerante per tubazioni lunghe.
Additional Charge
15.0 oz
Additional Charge vs Total Line Set Length
Formula
Refrigerant Charge Adjustment
Additional Charge = (Line Length - Factory Length) x oz/ft
AC condensing units ship with a factory refrigerant charge that covers a standard line set (typically 25 ft). For every additional foot of liquid line, extra refrigerant must be added per the manufacturer specifications (often 0.6 oz/ft for R-410A).
Esempio Risolto
50 ft line set, factory covers 25 ft, R-410A at 0.6 oz/ft, 96 oz factory charge.
- 01Extra length = 50 - 25 = 25 ft
- 02Additional = 25 x 0.6 = 15.0 oz
- 03Total = 96 + 15 = 111 oz = 6.94 lbs
Domande Frequenti
How do I know the oz per foot for my unit?
Check the manufacturer installation manual. Common values for R-410A are 0.5-0.8 oz/ft depending on the liquid line diameter and system capacity.
Can I have too much refrigerant?
Yes, overcharging causes high head pressure, reduced efficiency, possible compressor damage, and liquid slugging. Always verify charge with superheat or subcooling readings.
