After reviewing literature on small compressor
fridge/freeezers, I am wondering about the efficiency or otherwise of the smaller ones. Do you have any thoughts about it?
I am considering purchasing
a small portable compressor
fridge/freezer for my little boat
. Rimfire has no inbuilt ice-box, I have used a 55 litre camping one but it does not fit very well and with no nearby shops to where I will sail, replenishing ice is a problem. But the small fridges do not seem efficient.
Using Waeco as an example, average useage:
WAECO mobile solutions
CF18 (18 l): 1.2 A/Hrs [from some forum member
who emailed Waeco]
CF 25 (23 l): .84 A/Hrs [from Waeco website, same as all below]
CF35AC (31 l): .85 A/Hrs
CF40AC (37 l): .87 A/Hrs
CF50AC (49 l): .86 A/Hrs
The 18 litre fridge uses approx 50% more power than the 49 litre one. That may be because the smaller ones are made with a priority on portability, thus having less insulation
. It is a puzzle but the implication for me is that if the consumption
figures are correct, I am saving no power by going for the smallest one. I am bettter off going for the largest one which physically fits the space for it. That is, does not overhang the seat it will live on and the lid can be opened fully without hitting anything. What do you reckon?
Oh, I guess I could increase insulation
on a small one, those optional covers help with that, but that seems a bit like closing the gate after the horse has bolted.
