Title: looking for energy eff. fridge electric only
Post by: johns4104 on February 08, 2009, 07:30:19 PM
Does anyone know the kw/year usage on a summit cp97 or ff975ss
looking for about 7.5-9 cu ft with separate freezer.
I don't want to spend 1000$ for a fridge.
any Ideas?
Looked at old posts on the subject but it seems that the models discontinue quickly.

Thanks,
John

Maybe these folks can help. I see bad bad reviews on the summit. Try to get a Norcold or if you are only looking for 110V then maybe an appliance store?

John,

Looking for the absolute least current draw was a nightmare experience, for me at least.  I think I recall a 2 amp draw was the lowest.  That reflected the power in the compressor.  The annual power consumption was a measure of the insulation effectiveness.  Unless you buy really expensive "Sunfrost" type stuff, your selection will be spread over many brands.  You just have to look at them.  A higher current draw also implies that the compressor is larger and that the refer will recover faster. I think efficient utilization of interior space is also a big factor.

I know that the models mentioned in those old posts are no longer available.  But, look at the site for that brand.  Hopefully someone that has been thru this recently will chime in.  If not, please post what you bought and learned.

Thanks,

John

 At times going for the ultimate energy efficency is more time, trouble and money than it is worth !! I settled on a 11 cu ft fridge from a big box store.
An important thing here is "that model is no longer available" When I went to replace my fridge last year I had a very difficult time finding one that would fit my opening. In hindsight I should have took the one I had and had the compressor replaced. Leave yourself some xtra space around the fridge.

I find the Energy guide is a pretty good idea of how much energy a particular model will use.  A model that is Energy Star rated will use less energy.

My current fridge is a 10 CF Haier with manual defrost.  It has a 1.2 amp draw when running.   Other fridges have draws upwards of 4 or 5 amps, but that is likely due to the heater for the auto defrost.  You can often find ways to add a switch to turn off auto defrost when bonndocking.  Total energy usage is more important than amp draw.  A low amp draw unit might just run more to coll the same amount as a higher amp draw unit.
