Chest Freezers; What they tell us about designing for X

This video is super cool. We're talking about refrigeration, and how the design of a refrigerator affects its energy consumption. Freezers are the perfect place to see this in action, so let's take a look!

OK, comment-pinning time! I want to address the whole full-vs-empty fridge aside because I appear to have understood this differently than many people and it illustrates a problem in the video. Lots of people are saying things along the lines of "I thought the point of a full fridge was to minimize the amount of air inside so opening it causes less heat loss." Similar to the whole thermal mass reasoning (which is where I was coming from), this doesn't really matter in the long run. Which of course runs counter to the idea that chest freezers are helped by the fact they have a lid and not a door. So let's talk about that. The thermal mass of air is tiny compared to any solid or liquid substance. So even if you exchange the entire volume of air in the fridge or freezer when you open it, once it's shut the new air will rapidly cool thanks to the cold walls, shelves, and of course food. That's why the freezer door gets sucked in. This does introduce some quantity of heat, yes, and in theory if you had more stuff in the fridge less heat would be introduced. But honestly I think this quantity of heat is mostly negligible, and I regret not making that clear in the script. I think that the heat introduced from opening the doors a few times is minimal compared to an entire day's worth of natural heat intrusion. Chest freezers do get some help from the fact that they're sort of "never opened" but I think that more important than even that is simply their massive amounts of insulation compared to a refrigerator. I actually talked more in depth about this in a follow-up video, which you can find here; kzbin.info/www/bejne/eYOliIOYptukrNk (edited to add;) Having thought through it some more, I imagine the greatest benefit of having the lid on the top is that the cold air isn't being held back by a thin door seal as it is in an upright freezer. I really should get a thermal camera!

[@matthewpalmer9820]

You have the best channel on youtube.

[@mdr48371]

I think your point still stands that not exchanging the air in a chest freezer everytime you open the lid means much less ice buildup

[@LatitudeSky]

You can see this in action in grocery stores, where the meat cases usually have open tops. The heat gain from atmosphere is manageable and relatively easy to control, as long as the meat on display and the display rack itself remains chilled.

[@83hjf]

keep in mind "chest freezers aren't opened as often as a refrigerator". the tags you see on appliances are based on "actual usage", and the testing involves opening and closing the door "several times a day", thus losing some cold air in the process every time. chest freezers also have usage simulations that involve "opening and closing the lid much fewer times a day than a refrigerator".

[@whatmakesyourday]

One of the things I found to help with “things stacked on top of things” is having a smaller variety of items in the chest freezer and more variety in the upright fridge/freezer. I find that if I have 5 or 10 of each item, I’m not digging for them as often.

[@StephenBaylor]

I'm a refrigeration engineer, and I do a lot of thermal FEA simulation for heat gain and external condensation performance. For the bit where you were speaking of different configurations having similar internal volume, but different energy consumption values. There are some reasons such as the machine compartment, which can be 10°F greater than the ambient air, being directly adjacent to the freezer compartment on a bottom freezer. Also, the evaporator fan also has a more difficult time forcing air into a fresh food compartment above, rather than forcing air downward as in a top freezer. These are impactful, and certainly design considerations are made with this knowledge, but by far the largest factor is the DOE energy standard. Energy requirements are not just a simple formula for how much energy usage per unit internal volume across the board. The value for allowable energy per internal volume differs based on the compartment type (freezer vs. fresh food) as well as configuration (top freezer, bottom freezer, side by side, etc.). As you noticed, the allowable energy consumption per DOE is less for a top freezer as compared to a bottom freezer. Most refrigerators are designed to an energy standard, be that DOE standard energy or energy star, then internal volume is optimized to meet that standard.

Or Social Media. CV19 debacle has proven to me that those skills are nearly gone. They are not being taught in HS or College any more. Cognitive Dissonance is a drain on creativity and the joy of learning about how the world works. Unfortunately, I think that's the plan of psychopathic people who now oversee the "system".

Thank you for another great video; always fun to watch. My former refrigerator was a GE Profile, bottom freezer drawer with the dual zone compressor, no in-door ice maker. It was a wonderful unit and the Kill-a-watt confirmed it was very efficient. But with great frills comes great fails, as proved when it had a problem 7 years in. No repair service available meant I had a very expensive wall locker. I ended up going with a similar, fewer frills, replacement that costs $1 more a month to run. I hated using more electricity, but it can run for 140 years for the purchase cost difference.

Great video, I always enjoy your insights into seemingly mundane topics. In case it hasn’t been mentioned in the previous thousands of comments which I am admittedly too lazy to do more than quickly scan through, I just wanted to let you know for future reference- the term heat pump is generally reserved for a device whose useful work is the heat output. While all vapor compression devices could be used to move heat for a useful purpose in theory, a freezer does not put that heat into a used purpose, rather it dumps it into the space so it would not be considered a heat pump. It’s a picky differentiation and doesn’t really matter for the purpose of this video but in the interest of sharing knowledge I wanted to bring it up. Source: I am an engineer in the HVAC industry.

This channel just popped up in my recommendations and I'm glad it did. He is interesting and obviously well informed on the topics he chooses to make his videos on. I also really enjoy him. Lol. I like his mannerisms and cadence of his speech. Very relaxing, so if I want to nap his videos are soothing and long enough that I can slowly doze off but his videos are also very informative and make the everyday mundane things we use or do actually interesting and therefore easy to watch and understand. So the videos themselves aren't what makes a sleepy Jennifer. I can easily fall down rabbit's hole and while away a couple hours learning. Which has been one of the best ways I've chosen to spend my quarantine time, along with learning about the cosmos and astronomy, (I've actually just purchased my first telescope and I found Jupiter. I could see all the bands of color but not the giant storm eye yet). I've also jumped feet first into marine biology. Tho fascinating, that topic often ends up leaving me sad and very disappointed with certain members of our species. So those have to be watched on a good day, cuz they just make a bad day worse and we already have the pandemic and really stupid politicians doing that particular job for us, smashingly. Though I haven't caught his name yet, I would still like to say thank you. It's never occurred to me to research any of the everyday items and luxuries that we have at our disposal on a daily basis but this channel has gotten me interested in them. It's really interesting how the mechanics of it all works and I'm looking forward to going thru your video catalogue for curiosity and some times as a sleep aid to drown out nonsense noises, relax myself and get a restful, refreshing nights sleep. No nightmare inducing content here to mess up a good sleep and who knows, maybe my subconscious is picking up some of the info he is throwing down, lol. Thanks again. 10 out of 10.

[@ceraphi717]

im glad i went back and watched this!! intuitively, i guess i'd assumed that more expensive or popular refrigerators and freezers were inherently more efficient despite wanting the cold-hole storing capabilities of a chest freezer! i will keep this in mind thank you

[@vlogerhood]

"Assuming you have some storage" Fun fact. You can use a freezer AS electric storage. If when energy production is high you over cool the freezer, that is make it even colder than normal, then when production drops off you can allow the freezer to warm back up to normal temperature and not use the heat pump during that time. That essentially means the running of the heat pump later came be done earlier, which is equivalent to storing the power to use later. There are some huge industrial freezers that do this to save energy by working overtime when power is cheap and demand is low to help reduce grid stress and "store" power for later.

When my family got a bottom freezer they told me it was more efficient to have the freezer on the bottom. Since that became the trend I assumed it was true. When I bought my house it came with a bottom freezer. I was looking to replace it with the same kind, but now I’ll consider broader options now that you have made me a better informed consumer.

[@spikester]

It allows them to make a nice drawer for everything, meaning most of the cool air can remain inside in the plastic buckets everything sits in.

It does make it more efficient - for humans. Having heavy blocks of very cold boxes fall on the floor or your foot from 4-5 feet high leads to inefficient things like casts, braces, crutches, doctor visits, etc.And reaching down for something is usually easier for the elderly as well.

Good to know, you wouldn’t think a bottom freezer would use more energy. Then again, I go into the freezer less than the fridge, so I think I’ll still look for one on the bottom. And who would have guessed a freezer uses less energy than a fridge. Another well done, informative episode.

[@zoltanhorvath4532]

There was a mention of chest coolers. I happen to have a chest freezer that out of the factory had a setting on it's thermostat to keep it around 2-5 degrees C. I think it's identical size to the one in the video... I used it for a few years as a fridge/cooler with the occasional boost to get the beer cold faster. Yes, it was an effort to have a very energy efficient small house. And no, you do not need to keep eggs inside a fridge if you have a decent pantry, that's not heated. :) Back to the fridge: As it was opened more frequently than the usual freezer and it was not freezing, there was issue with condensation, that of course all went to the bottom. Cleaning it out really sucked. So using it as a cooler has a lot of drawbacks, but yes, energy consumption was definitely not one of them. Great content, thanks a lot!
