Long live the energy hogs!

Thank you so much for this!
So what I can tell is that the 31 DR machines with the open evaps improved energy use and capacity slightly but really improved ice freezing.
The CA machines seem like a marked decrease in energy use vs the DR. They also had a good improvement in capacity and ice freezing.
But it looks like the overall winner would be the CK of 35. I didn't know power usage dropped that much in comparison with the CA models. The ice freezing is also spectacular. I know for a fact that I can freeze ice in a metal tray in 30 minutes or less when I turn the dial to 9 to continually run the compressor. I then turn it back towards 5 after the ice is frosty. Very, very neat stuff!

Yes. The CK is king in dependability, energy consumption and power.

I think the FEA's beat them all, but style has to factor in at some place.

The fan and condenser also need to be cleaned which is another huge drawback over a CK. Also, not sure on what the cooling power of an FEA is compared to a CK? You're right, I wouldn't want an FEA even if it was twice as efficient and reliable as a CK, but it's certainly not as reliable as a CK.

Gee chrisj. I can think of another post on another forum that could benefit from this info. How do these "perfect world" numbers compare to those you're finding in the field?

Chris,
I'm assuming the 1945 unit that's listed on the paper would be something like an FEA. Even though those units have a fan they're very quiet in operation. I'm not sticking up for them. I'm just pointing out that the paper begins by mentioning the oldest DR's and going through the evolution of monitor tops and finally ending with an R12 unit of some sort.
Of course to be fair, if the paper would've continued on it would've went through the 50s, 60s and 70s and the energy usage would have gone up again before going down in recent times.

We also don't know how old the paper is. It could be from 1945-1950. Quiet or not, fans cause issues. If the fan doesn't fail it'll still plug the condenser up in time. I'm lazy and in 100% honesty defrosting my CA a few times a year is far easier than cleaning the nightmare condenser on our 2011 Kitchenaid.

The new condensers are a nightmare to clean. Most people don't even think about it and then their fridge goes tits up. Some manufacturers advertise that you don't even have to clean the air forced coils that are compact and next to the compressor. Makes no sense to me because it looks like they would trap more dust than the ones under the fridge body. They are so compact and tight! They mention in small text that if you have pets that you still have to clean it!

Chris,
I agree with you. You can clean the condenser on a FEA unit standing up. This isn't about durability, it's about electricity used and ice making capacity. What changed the evolution of refrigerators to change was need of increased freezer space. From World War II on the lower model refrigerators had smaller freezer spaces. My grandmothers 1951 Frigidaire was a smaller model refrigerator, but it had a full with freezer at the top that was clearly labeled super freezer chest. Frigidaire was proud of that thing.

When I was laying on the floor trying to clean it I thought "there must be a better way.." and then looked over at the monitor top and I'm sure my blood pressure went through the roof. We improved things.............

Our modern frig is near the back door. I put a old furnace blower in the doorway to blow the dust out of the house. Pull frig out ,remove kick plate and back and then use an air compressor on it. Only way to really get it clean easy.

Hi all and my first post here, this place has been a lot of help already, I've got many questions but here is one I was fixing to address... I have three square top monitors they all work in one form or another. The fan on one has never worked for 25 years it's my only everyday box and and I was thinking about fixing it.. I know why now? My question is will it hurt or help the fridge work easier? Thanks
