Calculations of HFO used liters when no HFO was actually flowing since the last bottle change (maybe 200/300 liters error in my calculations.....)
N2 and Ar at beginning of Septmber in HFO line at 6.4 l/h (before test beam)
from 01/08 09:20:00
to 16/09 16:10:00
01/08 -> 01/09 = 31 days = 24hrs * 31 = 744 hrs
01/09 -> 16/09 = 15 days = 24hrs * 15 = 360 hrs
---------
1104 hrs * 6.4 l/h = 7065.6 l
STD mixture with R134a in HFO line at 10 l/h
from 16/09 17:00
to 19/09 21:00
3 days 4 hrs = (24hrs * 3) + 4hrs = 76 hrs * 10 l/h = 760 l
STD mixture with R134a in HFO line at 10 l/h
from 21/09 21:00
to 23/09 11:00
1 day 14 hrs = 38 hrs = 38 hrs * 10 l/h = 380 l
Total = 380 + 760 + 7065 = 8205 l
