Calculation of additional refrigerant charge for the entire 3-WAY ECO-i system
(Additional refrigerant charge for entire 3-WAY ECO-i system)
= (Refrigerant charge at outdoor unit)
+ (Necessary amount of additional refrigerant charge per outdoor unit)
+ [Additional total refrigerant charge (before extension + after extension) ]
[Before extension : (11.8 + 11.8) + (0 + 3.2) + 11.99 = 38.79 kg ]
= [(11.8 + 11.8 + 11.8) refrigerant charge at outdoor unit]
+ [(0 + 0 + 3.2) necessary amount of additional refrigerant charge per outdoor unit]
+ [(11.99+1.46) additional total refrigerant charge]
= 52.05 (after extension)
