No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.

Replacing an old mini fridge (self.nostupidquestions)
submitted 2 months ago* (last edited 2 months ago) by Lifecoach5000 to c/nostupidquestions
 

I have a 24 year old mini fridge that’s still alive and kicking. It’s a model that actually also has a freezer compartment.

I’ve been thinking about replacing it - especially since the freezer portion no longer works. But I was also curious how much more energy efficient fridge tech has gotten in the past 20 years? Like would I make up the cost of a new mini fridge pretty quickly based off the less power consumption?

I actually have one of those electricity monitors hooked up to it logging the data and I’m still kinda researching - but thought hey I’ll just ask c/nostupidquestions and maybe someone here might know right off the dome! Thanks in advance

The manufacturer(s) will publish an energy guide label with their estimated kWh/year energy usage for any given model. Using your Kill-a-Watt or whatever energy monitoring device you have, it should be fairly trivial to measure a day's worth of energy consumption from your old fridge and multiply it by 365 to get a yearly figure.

Then just see if A < B.

I'll start with among the cheapest and junkiest available, the Avanti RA31B3S (which has a separate freezer compartment). The manufacturer claims it burns 320 kWh/year.

Yeah that’s kinda what I am doing. If I’m using this energy monitor thing right, the fridge is on Day 9 and has used 20.32 kWhs

[–] dual_sport_dork 10 points 1 month ago (1 children)

If that pattern holds then a modern one should be ~4x more energy efficient...

Also bear in mind that there is only a single evaporator in that thing, so it's not a case of "just the freezer isn't working." The refrigeration system in there has partially failed, wholesale, and you only notice it first in the freezer because that's the coldest compartment and stuff melting is a very obvious tell. That fridge is probably working its compressor constantly in a vain little mechanical attempt to reach its temperature setpoint, which it will never accomplish because it's lost compression or has a slow refrigerant leak or whatever. So it's consuming even more electricity than it otherwise would, and replacing it with just about anything would be a net improvement.

Yeah that’s something another commenter mentioned. Thanks for the math. I think it’s time to say goodbye to this old thing…

Maybe I’ll try this on my big fridge next. It’s getting close to 20 years old itself but functions fine.

[–] dual_sport_dork 4 points 1 month ago (1 children)

If you want a good laugh, or possibly just transform into a pillar of salt, you could stick a temperature logger in your fridge to see if it's actually holding its setpoint (your big one, that is, not the mini fridge).

I did that in our office fridge a few weeks ago just for a lark. The results were... not good.

I know this is random, but I like your writing style. You manage to throw in flourishes of language and colour, even dramatic biblical references, when talking about nothing more than a broken fridge.
