It actually makes sense for it to use a reverse cycle for heating instead of a conventional heating element, since using a heat pump will move somewhere around 2.5x the heat energy per unit of input energy, so for the same heating power you’d get substantially more battery life out of it.

[@AlecThilenius]

This. Heat pumps are incredible. Ex it's more efficient to burn coal/gas in a power plant which drives a heat pump to heat a house, than it is to just burn the same thing it in a furnace to heat the house directly. Seems to violate thermodynamics, but it doesn't.

My favorite lab in engineering was a transparent tank full of freon. You could crank a wheel which changed the volume on the tank. The whole thing was in a constant temp bath and when you cranked the wheel and shrank the volume the freon would start raining out of its own gas. There was some experimental crap involved too but turning the wheel was fun. 😅

[@tyrannosaurusimperator]

My favorite lab was compressors. They had recently completed renovations on the building and the professor was too stupid to realize the compressor needed to be hardwired for 240. We stood around and looked at it while the TA explained what it should be doing for 10 minutes and then we left. Of course, writing the report was brutal, but I had a spare 3 hours on lab day.

I have one of these coolers, and it's a nice piece of gear. Particularly handy on long road trips.

Seems like it shouldn't have been that difficult to integrate a charger.

For a fleeting moment I had high hopes in peltiers. stacked several dozen together only to find at the end of the day a gallon of cool water and an energy bill to be embarrassed of. I had discovered these compact compressors and bought a lesser known brand of ice chest with it built in to take out. I had yet to do so by now as in initial testing, it could get sodas cold enough to the point they explode, I've enjoyed taking it on every trip since then. Mine didnt come with the ease of slotting batteries into, but after testing it to use 50 and 30 watts in normal and eco respectively, figured I could use any lithium battery or even a small solar panel.

[@docferringer]

Did ya know they made a cooler box for your lunch that snaps together with your rolling tool storage cart? GENIUS. Also! The refrigerants these days are built to be different in one key way: It doesn't explode. Propane and such were originally used for those fancy victorian refrigerators, but the kitchen staff often complained about the cook dying when he lit the stove.

[@nolanhoffman2853]

That’s not strictly true. Original refrigerants were explosive in the ‘30’s. Then they were tired of explosions, so moved to HFC’s which turned out to be not highly toxic or flamable, but God-awful for the environment ( 1 molecule of R-22 can destroy 100,000 molecules of Ozone and can stay in the atmosphere for decades) then more recently developed refrigerants have gone back to butylethylene and propane, which are explosive but thanks to modern safety standards and higher quality of materials are much less likely to leak, so on balance are much safer.

[@MacRobbSimpson]

True, though we are using R600A (isobutane) in a ton of modern chest freezers and small fridges. My understanding is there is a limit in number of oz of the stuff allowed, so it's only used for smaller things... but that's why you can buy like 3 7-cuft small chest freezers for the price of a single >7 cu ft one which does *not* use the cheap R600a.

Technical details: Peltier modules are a bunch of diodes places between two plates. They work in both directions.... you can push electricity through them to have a heat flow (or produce cooling, your choice).... you can run them the other way and if you create a heat flow then it will generate electricity for you. A Peltier module is a machine, whereas the Seabeek effect is just a physics principal, not a thing you can use. This last point I am fuzzy on so google if you care, but Seebeck effect may not be related to a Peltier module and instead be related to a thermocouple. Thermocouples are neat in their own way but different from Peltier modules because Thermocouples have no diodes, they are literally just two different metals mashed together, and they create a tiny electrical signal related to their temperature that you measure with a meter.

[@JCGver]

Nope, Peltiers are a whole bunch of thermocouples between 2 plates. You can reverse the voltage on a peltier element and the hot and cold side will swap. If it where diodes instead of thermocouples reversing the voltage would lead to nothing, you know the thing that defines a diode. You can make peltier elements with N P junctions, but the ones on the usual online scumbacks use the thermocouple version.

Yeah. I can understand the skepticism around the massive complexity of climate models, and the quality of data fed into them. But acid rain and ozone depletion were pretty low dimensional problems with well understood causes. Nothing to be skeptical about. And barely any modelling needed.

[@ProtosR]

yeah exactly. saying you survived the whole in the ozone while completely ignoring the active work that went into fixing it is just ignorant, not surprised though.

[@jim4556]

You'd exspect a steep decline being that today the amount of time people spend outside has fallen alot and the chemicals we put on our bodies and clothing supposedly moved away from most of the real nasty cancer causing stuff.. so I wouldn't contribute that to the ozone layer being restored

@@ProtosR B.. bbb... but we can measure the Ozone concentration directly. And we understand the relationship between Ozone and UV clearly, and we understand the relationship between UV and skin damage well.

I did a project with peltier modules in college. How I understood it was between two ceramic plates are a grid of wires where two different metals are welded to each other and evenly dispersed across the the plates in the same orientation. As electricity flows through them electricity excites the welds in the same fashion that a cylinder of air being compressed heats up and when electricity flows the opposite direction it’s as if the cylinder of air is having its volume expanded. They are very fascinating to hold while energized. The more effectively you cool the hot side the colder the other side becomes in vice Versa however their energy effectiveness is nothing compared to an hvac/ refrigerator unit. For small projects they work fine but fine temper control is difficult which is why they are not used to cool components on computers.

[@superczech69]

I concur, sir! It's about time somebody helped out the outdoor, onsite kinda folks!

[@DUKE_of_RAMBLE]

For Part 2, it'd be interesting to know how well two Deep Cycles in parallel (or even just one), can run it from the cig adapter... ALSO, might need to check the manual, but perhaps it's meant to do the heavy lifting while plugged in, and then the batteries are for more for station keeping duty? And does this _also_ double as a battery *charger* for the Makita packs? (when the adapter is connected)

[@AlGoYoSu]

Not an expert, but read something on the recent history of car refrigerants. IIRC R-12 was something like 500x as bad for the ozone as CO2, so 134a at 50x came through.Then R1234yf at only several times as bad as CO2 came about. Now, R700 is the modern flavor of choice for refrigeratant, while only equal to CO2 at damaging the ozone it functions at much higher pressures. This requires higher quality components, and is currently much more expensive when comparing the refrigerants. The article mentioned it is already in some European models. The powers that be (depending on the local) have not outlawed the production of 134a so our non late model vehicles will have plenty of supply for the future. One issue people talk about is modern refrigerants are flammable unlike the classic R12/134a hence the warning sticker on this Makita cooler/heater.

[@TacticalBaconPatches]

R12 got the axe because it depleted the Ozone (also has a GWP of 2400 but they didn't care about it then). Then they went after R-134a because it has a Global Warming Potential of 1300. 1234-YF has a GWP of only 4 even though when they passed all the laws to force cars over to it, it magically had a GWP of less than 1. The new stuff they're testing in Europe is R744 which is CO2 based so its GWP is 1. It's all a game.

[@leftyeh6495]

Well, until they stop with propane there will always be a way to charge your AC if you're not worried about the whole flammability thing

[@TripleSuccotash1]

it said on the label it contained refrigerant, it wouldn't have that if it was an electric chiller.

[@TheMobilefidelity]

Propane actually works better than any of the fluorocarbons. Companies just don't use it in Murica cause it's highly flammable. Very common in Europe and elsewhere. Also known as R290.

[@tomtheplummer7322]

Ammonia was used as refrigerant too. Even Swiss Family Robinson did it. 😏

[@andrewt9204]

Hydrocarbon based refrigerant is starting to be used more in the US now. I think there's a certain volume limit that can be used for indoor residential. My new fridge uses R600a I think it was, it's a butane based refrigerant.

[@brotang2953]

I recently brought a 12v fridge/freezer made by a company called brass monkey. Its pretty heavy on power consumption but keeps things frozen and cold when the power goes out at least. That thing looks pretty decent and the battery arrangement seems pretty simple.

[@procrastinator1842]

I have the 15L version and it lasts 12-24 hours on the 15.6Ah interal battery, and charges while I drive.

[@dragpix]

I have same brand here, but the 25L version. zero complaints at all. Lives in the car on a second battery (deep cycle), will go for 2-3 days on 75Ah before low voltage protection kicks in. 2nd battery charges via alternator when cars running.

[@Karjis]

@@dragpixyeah I have 15L Mobicool one and that also seems to be on similar level on power. I would not run Peltier-box in a car overnight on road trips, but with compressor cooler just no issues. Basically drops the voltage of 70Ah battery for 0.1-0.2V overnight so no worries for starting the next day. It runs few minutes about once in an hour or twice if you open it.

Im a Quality Analyst by trade; if anyone wants to do some studying on why Japan is so damn good at everything, look up Dr. W. Edwards Deming. After WWII Douglas Macarthur sent Americans (especially Christians) to Japan to teach them how to rebuild their industry, Deming was one of them. They learned so well that they became world leaders while the US forgot the things we taught them. It's a whole new philosophy where you blame the management for problems instead of the operators, meeting specifications isnt good enough (see the Taguchi Loss Function), and businesses exist to serve their customers and employees rather than give dividends to shareholders. Quality is not a department or a measure, it's a comprehensive worldview.

[@inh415]

I would want it to use the compressor for heating in order to extend the run time 3 to 5 times VS resistive heating.

[@WeighedWilson]

So is resistive faster but compression more efficient? What's the trade-off?

[@inh415]

@@WeighedWilson trade off would be size, weight, complexity and expense and that a compressor won't be able to go much above 60 / 70c. Already have the size, complexity, expense and weight covered as it is needed for cooling other than one extra expansion valve IIRC. Adding a separate resistive heater and control circuitry in this case may even be more expensive.
