I think the Helia has the same 2 drawer Stainless drawer as fitted to the Lipari
Evolution made by VitriFrigo. I have just had the meter on for the last few days. It is still Queensland
Winter so cool but not Freezing and not hot. Daily 24hour draw was depending on settings on the fridge from 28AH for 24 hours to 30AH.
I'm still running another test today so will have better info tomorrow. I can publish the graphs if anyone is interested. Fridge temp measured at the top of the fridge is approx 7 degree C and I have been making sure it stays in the 7 to 9 range while testing. Is measuring at the very top of the fridge so is the worst case temp.
I have been testing the effect of compressor
speed on power usage, temperature and cycle time. Very interesting numbers. The EvaKool 60 Ltr freezer was very efficient on economy mode with temps at minus 16-18 C using less than 18Ah. The little EvaKool 45 "Bar fridge" ok at 15.4 but it does get opened more than the freezer. All three fridges use Danfoss BD-35 compressors.
Slowly working around the boat to see what the actual usage is on each component/circuit.
