Hi Expert Guys,
I have BScience ULT 100l. First stage R290 0,12kg. Second stage - they write - R1150 0,029kg+0,056kg. Freezer have 2 comressors SC18CNX.2.
It is very sensitive freezer for ambient temperature.
1. Do you know why they write two amounts in second stage? It is charging in two steps?
2. How they charging this stage exactly 0,029kg R1150? Is there any special weight or other?
3. How they calculate cooling capacity of SC188CNX.2 @ -96C to achieve -86C in the chamber?
;)
Regards from PL
