That's an expected cost of old fridges, so I don't know that it's unfair. A major reason old machines are less efficient is accumulated defects (people too!). If I said comparing a new car's fuel efficiency to my old one was unfair, because my old one has a lot of problems, you might say that's very fair.
- chii 1y agoit depends on why and exact purpose of said comparison. If the comparison is meant to show the drop in efficiency as part of age and usage, then yes. However, if you wanted to _only_ compare design upgrades, you don't want wear and tear to confound the results.
- tonyhart7 1y agobut you cant compare only design ???? there is no one selling an 30 year old fridge "new"
- rajamaka 1y agoYou can restore the old fridge
- aspenmayer 1y agoUnless you have a fridge assembler from that same factory with the same materials also on ice, modern tools, techniques, and methods would make this an exercise in futility with regards to an apples-to-apples like-new comparison. We don’t even use CFCs anymore, for one.
- chasing0entropy 1y agoYou're sidestepping the point with valid re-herrings. If the old refrigerator's compressor hardware were left unchanged, possibly repairing the thermostat or contactor causing the malfunction, cleaning the air exchanges, and replacing the seal: based on the OPs own usage chart would have consumed equal if not less energy noting it was a dual compressor model.
- aspenmayer 1y agoAre we making an accurate comparison considering the internal cooled space of older fridges versus newer ones? Many older refrigerators were smaller, so the same power consumption for a smaller internal volume isn’t telling the whole story, but I digress.
- rob74 1y agoI would say it would be fair to compare a new fridge with a 30 year old fridge in good working condition. And a fridge that has one of its two compressors running all the time is obviously not in good working condition.
- therealpygon 1y agoYeah, I too am unsure why anyone would think comparing a 30 year old fridge in the worst condition for testing is somehow a useful comparison in any meaningful way. Is it really normal to want an off the line 2025 Tesla and a 1985 Lincoln Towncar with 376k miles on its second motor with a missing cat that was stolen last month for a quarter mile comparison?
- modo_mario 1y ago>If I said comparing a new car's fuel efficiency to my old one was unfair, because my old one has a lot of problems, you might say that's very fair. If it's a simple as not driving the old one with punctured tires and replacing those first to get a dramatically different comparison then no i'd say it's unfair. Replacing a broken thermostat or fixing a rubber seal isn't a huge thing. Why else make the comparison? Who cares about this broken one?
- mmooss 1y agoIt depends what you are comparing: If you're comparing technologies, then you want to eliminate the variable of condition. If you are comparing the values or efficiency of actual old fridges and new fridges - for example, to decide whether to replace the old ones - then it's false data to assume the old fridges are in the same condition as new ones.
