    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; clip-share.net/video/CRBWPbqvqvw/video.html
    (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!

      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

      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 3 years ago +28

      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".

    A good organization trick for chest freezers is to use reusable fabric shopping bags of varying colors to organize your food into the bags. Keep a key to what is in each bag taped to the top of the freezer.

    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.

    Good video. As I am a developer for thermodynamic systems in fridge I barely have anything to object. Comparing a top freezer to a bottom freezer makes not much sense. The French door is so much inefficient due to an electrical heater preventing condensation between the doors. 10-30% overall depending on the model. Manual defrost models of bottom mounted freezers are quite common in Europe btw. I defrost my Bosch every 2 years.

    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.

    I have a chest freezer but I keep it at 3C because it's full of kegs for my bar. It's super handy for that. I also have the freezer at the bottom/ French door combo in my kitchen, as I find the fridge being that height more convenient as it's the part I use most. Honestly it's worth using a bit more electricity for me.

  • Logan Fisher
    Logan Fisher 2 years ago +6

    If you're going to buy a chest freezer, I highly recommend getting one with a sliding internal shelf. Yes, for it to actually be usable, you then can't use all of the space (as otherwise the shelf would have nowhere to slide to), but you still get 3/4 of the total space and MUCH greater accessibility to everything inside.

    I think the reason bottom mount French door refrigerators are the the most popular is because placing the fridge compartment and thus the compartment you will open most frequently higher up means less bending down. Each of the double doors are smaller then one big door so it is good for smaller kitchens or families that may have multiple people in the kitchen at one time.

  • Bear Rides! Motorcycle Vlog

    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.

  • Mike Caldwell
    Mike Caldwell 2 years ago +14

    A thought on bottom freezer with pull out drawer requiring more energy: when you pull out the drawer, you're removing the contents of the drawer from the insulated box. While it's relatively brief, this removal allows for a greater amount of heat exchange between the items in said drawer and the surrounding warmer air. It's also likely a greater amount of cold air inside the freezer will be exchanged with warmer air from outside the freezer simply due to the action of a greater quantity of items moving in and out of the freezer area. Does all that add up to a 20% difference? Likely not and as you mentioned, the ice maker likely contributes to that difference as well. However, I suspect it is a factor in the increased energy need.

    • Paul K
      Paul K 10 months ago +3

      Also the compressor unit produces a lot of heat, and that is always at the bottom of refrigerators for some reason. So if you have freezer on top the hot part of the fridge is really far from the coldest part of the fridge freezer combo. But with freezer on bottom, the hot part of the refrigerator is right next to the coldest part.

    • Sidicas
      Sidicas 10 months ago +1

      ​@Paul K Heaviest parts of the fridge are on bottom to reduce tip over risk. If you put the compressor, condenser coils, etc. on top along with the evap coils that are already on top. Then it'd probably be code to require that the fridge be bolted to the wall.

    • Le Doynier
      Le Doynier 9 months ago

      Also the metal sliders bolted directly to the door body will act as heatsinks to conduct heat inside the freezer. It makes insulating them more complicated, or impossible if the slider arm is also used as a shelf (and then resides in the cold compartment constantly instead of being sunk in the insulated outer shell).
      That added to the causes you outlined just makes it a piss poor design overall :)

      Great comment. I was looking for a better explanation for this because .. you know .. cold air sinks and stuff, right?

    Thanks for your interesting video it confirmed my technical knowledge until my chest freezer died in may last year. I've to look for a new one (300liters) and knew the old one was using more than 1kWh a day for a twice a year, instead of a monthly manual defrost model. I've bought more baskets to better organize and limit the open door times a little bit. Surprised that a new front door was doing better. I now have the Siemens front door GS51NDWDV no-frost model that, measured with the same power logger, less than half of the energy 0,4kWh a day.

    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!

    I actually have a french door freezer(second hand, it was a steal after cleaning it) and there are, in fact, two ice makers. There is one in the door for putting in your glass(that door is remarkably thick) and the one in the drawer is useful for filling up your cooler for work or whatever else you need large amounts of ice for. It has a button to turn either one on or off.

    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.

    Nice video, clear and informative! The key factor for real life energy consumption of a refrigerator is ambient temperature. Living in a colder climate if you place the cooling appliance in the garage (or any unheated area of your home) this will significantly reduce the energy consumption year round. But please note a fridge/freezer with a mechanical thermostat located in the fridge does need to operate at room temperature.

    A very interesting and efficient device is the electric showerhead. It's totally safe, almost everyone in Brazil use them every day and most houses here are not grounded. It spends lots of electricity, of course, but I'm pretty sure people in colder places would save a lot of money by using their boilers just to avoid freezing and heating up water just at the point you need it - and only to the degree you want it to be.

    You probably should have mentioned that these days most freezer units which are located at the bottom of fridges are divided into compartments which slide open but are only accessible from above. This means that all of the cold air is still 'sitting' in these drawers, much as the cold air sits in the chest freezers.

    My vertical freezer has three drawers which minimizes how much air falls out when you open the door.
    I have a 12 volt fridge which I only use for camping which is a box that opens on the top and acts like a fridge but can act as a freezer if you wish.
    The idea of adjusting a chest freezer so it doesn’t freeze the milk is an interesting idea. There is a trade-off where you have to stack food perhaps keeping it in cardboard boxes might make that easier.

    Chest freezers are perfect for long-term stuff like meat storage, where you might stock up due to sale or in preparation for a large event like a family gathering or a holiday, but for day-to-day use upright freezers are better. If you are well organized and store the same products stacked in wire baskets, you can simply pull out the entire basket take what you need from the bottom to keep it rotated out with the freshest always being on top so that way you cycle through older product.

    I think another part of the reason slide out drawer bottom freezers make it less energy efficient is that you are exposing the entire thermal mass to the outside air. The drawer itself has some insulating but the exterior of the insular I’ve layer will absorb some heat and then take it back into the freeze with it, as well as the turbulence of the air causes some of the cold air inside the drawer to essentially “slosh” out like moving a large tub of water

    I've seen commercial chest fridges on sailboats - probably because of their energy efficiency, their ability to keep stuff inside even while sailing through heavier seas, and because they're small enough so that you can still rummage through quite comfortably.

  • Adam McInnes
    Adam McInnes Year ago

    Speaking of efficiency of chest freezers and access, check out the fridge built by Bill Lishman (the same guy who inspired "Fly Away Home"). His fridge was designed to have the shelving sit inside of a large drum in the counter and the shelving would pop up from the drum using air pressure for easy access, and the shelves were set up as a lazy susan to make access to everything much easier. This improved efficiency because the cold air remained in the drum rather than flowing out of the fridge, so stuff stayed cool longer.

  • Stephen Baylor
    Stephen Baylor 5 months ago +17

    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.

    Here in Thailand there are manual defrosting fridges. There's a button you have to push whenever you want to defrost. There's a small bucket just above the compressor and by the time you need to defrost again the water should already have evaporated. But if you let the ice build up too much you'll need an extra bucket.
    By the way, we don't call them French/American fridges. We call those "twin door fridges".

    "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.

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.

      Only thing I can think of is that there’s only one other model in this ones “class” so they can only compare it against that single value

      No, actually, it’s the unelected, non-accountable government bureaucracy at work.

      Does that mean you get a $4 rebate / year from the power utility LoL.

    Thats right! French-door bottom-freezer unit does in fact have its icemaker just in the door of the fridge, accessed with that gray handle on the interior edge, and is why the left door shelves are so much narrower

    I'm late to the party but as I am wondering how to preserve food in a boat for long periods, this was mighty interesting. Thanks.

    Purpose made chest style refrigerators are a thing though. The place you'll find them most often is in the galley on a sail boat. Why probably goes back to the days of ice chests. Ice chests in boats have always had the door in the top instead of the side as was common in home ice chests, and since many sail boats *still* regularly feature an ice chest it probably makes sense to use a similar style refrigerator on a boat, especially if it's a retrofit that replaces the ice chest.

    You are an international treasure (since I'm not from the US).
    I do really enjoy the depth of your knowledge with such a funny cool way of delivering it.
    You are one of a kind ✨️

    yes! my parents fridge has an ice maker in the door lol, it’s pretty cool but it’s small so it doesn’t make/hold much ice.. maybe enough to fill the hopper with 4-5 glasses worth of ice

    Alec: "Seriously, if you have a chest freezer and a leaf blower at home, try it. It's fun!"
    Me: tries it, "Wow, this is fun!"

      If you think that's fun, try cleaning the opening and the seal with windex first!

      to be fair there aren't many activities involving a leaf blower that aren't fun. I like the swooshing.

    Started looking into this again. Over been keeping my house at around 78f this summer which is fine for me but everything meant to stay cold is working harder. So I keep my computer in my basement but my fridge is still in my kitchen. I'm looking at a small chest freezer with a low temperature of 39f. If I understand this right that's above the optimum fridge temperature. Walking to my basement to grab something to drink or unfrozen food (most of which I cook the same week) which progressively gets moved from my freezer. I don't need an ice or water dispenser so I don't see any downside other than the extra walking, which isn't bad anyway.

    we had a manual defrost fridge that was old but still worked and the plug in meter said it used less electricity than the new fridge so I still kept it around for when we needed more space.

    I use a RedBull CanCooler V2 in my shop and it's basically a chest fridge. Barely even has a lid but you know barely any heat is lost and the sides are so thick. Excellent cooler.
