I found out, and others here have stated, the orifice tube is WAY too big for any estimated possible pump output. The principle is correct, the parts used are not... Everything you just said is basically right...

I don't deny the principle but the execution would not work, he put the fan between the two coils so the hot air would blow on the cold part (or vice versa) and result in no drop in temperature. The claim of -32°C is completely exagerated bullsh*t which he made putting the whole contraption in the freezer and then using a spray can and reversed the video while it was thawing Max you could get in optimizing his current setup would be a temp differential of 10-5°C given the power of his battery

You can make up for the difference in charge. See "superheat". It won't be as efficient as it could be but as long as the refrigerant is seeing both liquid and vapor states on each side, it will move an amount of heat. The thing that jumps out at me is actually the battery lol... It satisfies "that's cute" and little more. I don't think the same battery would have held on for the entire run, but I wouldn't know for sure, as I haven't tried it or even done any of the math. I'd say this one is sketchy but maybe not entirely impossible.

Wouldn’t 30psi almost immediately pop off those silicone tubes that don’t seem to be secured in any way? Also at 7:36 the water drops on the capillary tube are going backwards as if the footage is reversed, so he probably used an air duster can or butane to get the frost effect and play it backwards to make it look like it was spreading, and at 6:56 it starts forming on the wrong side of the coil first.

@@davidsmith3302 Shame it was "almost", that would have made a stellar video.

And also the water drop going backwards

pump's membrane would freeze, the pressure of the butane would def come out of the silicone tubing, didn't run a vacuum on the system, and ya the droplet on the outside of the copper tubing suggests that he figure what the hell, I spend all this time making this video and failing on this short-sighted idea that he'd make it work by saturating the evap with butane before taking final shots. XD what a hack!

even if he did manage this, the butane would eventually permeate through the gaskets/mambranes//silicone, I can think of 100 ways that this system will not function for any useful amount of time if at all

@@timhinchcliffe5372 when did you learn to take a joke so seriously?

@@uniqueprogressive9908 when did you?

@davidsmith3302 To achieve the negative depth of - 32 degrees shown on the heat gun, do you know how many psi of compression must be needed to escape through the cable and spray into the evaporator? and at - 32 degrees, the humid air in the system that is not drawn out will freeze and cause blockage of the injection cable! Let's experiment, not just theorize, my friend

It blatantly does work. It's just less efficient that a production system, but it proves the concept very well. You could have gone the whole hog and said the system does not include a dryer, has not been vacuumed down etc, but that is not the point here. And the reason the tubing works is because it only has a small pump rather than a big compressor.

probably pumped liquid nitrogen or just refilled with liquid butane again. Even the hot side is in the negatives

saya mencoba dengan pompa diafragma kamoer 3 bar,belum berhasil karena pipa karet terlepas dari pipa tembaga akibat terkena tekanan gas butane

capillary tube does determine the health for general units, but in this instance i think this is sufficient

I wanted that too! (AND, he never hit off-target to see if readings were true - was the thermogun, was his gun calibration skewed?)

It's fake, but my comments explaining it keep getting removed!

@nielsdaemen Well, one might question the pump being able to generate enough pressure running on the 9V battery, it does seem to slow down which I would expect to happen pretty quick, not much energy there. And the capillary tube ID might be a bit big, but then the pump probably isn't generating that much pressure drop across it. I'm sure some of the HVAC could show us the math of the minimum pressure drop needed...

@@davewright3088 Indeed I run these pumps from a bench power supply for my tests because a 9V battery can't provide enough current. These pumps can only reach 1 bar so I use two in series. Butane can make a 20 °C difference at 1.5 bar pressure diference

My home AC at home does not use Propane, Propane refrigerant is R290, witch is used a lot in Restaurants, under counter Cooling boxes ect. and some older Refrigerators. Residential AC systems used to use R22, witch is being fazed out for R410, witch is not flammable. Cars use R134, witch is also not flammable. for any of these gasses to be flammable you need high oxygen levels. You need to do some research before talking out your butt.

​@@McCuneWindandSolarWhat research does he need to do? He sounded pretty spot on. R290 CAN be used in just about any a/c system, especially the old r-22 systems. Its VERY common in Europe to used in residential a/c. But since the US is full of pussies that are scared of being "blown up", and since its available everywhere there's no money in it, so naturally it got a bad rap. So just because YOUR system doesn't use R290, doesn't mean the next persons system can't.

​@@aaronk.4694 R22 runs at a higher pressure than R290 R22 high pressure is 250, and 410 is 480+, and R134a is from 100 to 250 psi pressures are all different. the fact is this video what he is doing will never work. even if he used butane

He didn't vacuum the air out of the system though. Air has moisture in it, and it will freeze and clog the system.

​​@@davidsmith3302So this system will work indefininetly?

Are you guys mad or some thing this is fake you need much higher pressure pump for this to work if you want to learn about this watch hyperspace pirate

​@davidsmith3302 I started checking the comments section because the first one was "fake" . I'm not a specialist in air conditioners, but I do understand physics and I was wondering what part of the system was phoney because as opposed to a lot of the rubbish you see on yt, this looked pretty sound.

@@Newlife-ol6pk It's fake, there is no high and low side, 9v battery and that pump are no where near enough power to power a compressor to actually do what he's trying to trick people to believe he's actually doing it.

¿Pero si hace frío? ¿ Si congela?

@@Jesucristoesreytv yes

Or a soup can, etc.

The expansion occurs at the capillary tube, not the larger tubing. That larger tubing was used only because his pump had different sized ports... The large tubing is on the hi side (compression), ~17psig or more, depending if there is propane content mixture. Cooling coil is under moderate vacuum...

@@troubleshooter1975 I've been considering making something similar, a small scale unit, although the cooling coils wouldn't be concentrated, but bonded to a stone slab. Basically, a basic chilled kneading board for breads and pie crusts that can be lifted out and swapped with a modular cutting board when needed. The refrigerant of choice for that, propane. If I want high efficiency, I'll order a fridge, for that, something like this would be more than sufficient. Just was uncertain as to the size of the capillary tube. Although, I'd probably add a desiccant drier in mine, since it'd be for regular usage, not just a demonstration unit. I considered an adsorption fridge, but this wouldn't need a heat source. BTW, did you know that Einstein designed a refrigerator for a cousin? An adsorption model, apparently it did enjoy some success.

@@spvillano Absorption cycle is still employed for the RV industry... A stone (or ceramic) board is going to be a BIG heatsink... It will take a while to chill the thermal mass (I think you'd have to prechill it in a fridge, then it could keep it cold for bread, candy, or whatever). I don't think it is going to be as 'tiny' as you imagine. The condenser I think will be bigger than the stone (so another words, big area). It will probably need 1/12HP compressor. A scrapped bar under-counter fridge would probably be perfect. HVAC system fitters here may help you; you at least will have to consult tables to match up your components...

da f*ck.... 7:35 water is evaporating backwards ?

@MrPlastkort Actually no- I too was looking for positive proof one way or the other. If that was water, then it should be collecting and growing. If it is leaking butane, or freeze spray, then it will be evaporating, and shrinking. I scrutinized that closely, and unfortunately, it appears to be something evaporating. This part, at least, appears to be played 'forward'. The telltale is at @ 7:35 where you can see bubbles forming INSIDE the drop. There is one key moment where you can see two tiny bubbles that coalesce into one bubble; something that only happens in a forward direction. Other clues that I couldn't prove: Fan rotation; does it run backwards: Rotation on video can render wrong so hard to tell. Can't read the label to see if there is a direction of rotation stated. Didn't see anything in the vicinity that could reveal direction of breeze or 'sucking' a blown object. Setting things down: When he put the battery down, and when he connected it: If someone puts something down, or attaches something on, without having a grip on both surfaces, then it will show if it is running backwards. If items 'attract' to his hand that he sets down, or looks 'magnetic'; or battery clips that precede his finger and connect themselves without fingers gripping on both sides of it. I watched carefully and unfortunately he maintained contact with items until they were fully on the table, and held both sides of the battery clip, so I couldn't tell if it was off and pressed on, Or, if it was on and he pulled it off... I don't have free time to review it frame by frame. The way he filmed and held things, it is not easy to see if it is backwards or not. [and it can be a mix of forward parts, and backward parts. Each cut complicates analysis.]

And previous freeze / dusters were R-134a (I think they were a CFC originally?)

TODO EL PROYECTO NO DEJA DE SER UN JUGUETE DE NULA UTILIDAD.

Evap would get colder sooner if he got the fan away from it. Should be blowing that across the condenser alone.

Lol not even close. This is a DC motor piston-diaphragm pump with a "crank" mechanism. A fish tank pump is a vibrating diaphragm using a magnet and the AC mains frequency to drive it. One has notable compression capability with reasonable flow rates. The other moves tiny amounts of air at in/WC level pressures. They are not remotely alike in ability.

vapour absorbtion right ?

@@Team_Reaper. I don't know how it works exactly There is something that happens when it compressed the gas It causes the vapor to become liquid and then it changes back to a vapor The cold liquid is warmed by the air in the room and changes to a vapor and gets sucked by the compressor and changed back to a liquid. The A coil runs through the vent and the blower pulls warm air across it and the heat absorbed in the return lines is blown across exhaust fans outside and they exhaust the heat into the atmosphere In these warehouses they usually had the compressor and the condenser coils in the basement and the air was brought in from outside and passed over a heat exchanger in the basement to use the cooler air naturally occuring underground to make it more efficient

It's completely fake anyways

Correct, if you want it to work properly. Or you could just purge it with the butane before closing it up [take care; highly flammable and explosive]. You would need the right sized capillary tube. This was just a demonstration [or a fake].

they actually make mini rotary compressors for like $300 that are the size of a coke can. But yes this is completely fake.

It's fake, but my comments explaining it keep getting removed!

Then you know this unit is useless. Any btus absorbed by the cold end are just released out the other. It won’t cool much as designed.

@@rickschlosser6793 Exactly, but it is possible to create a working heat pump like this with upto 20C temperature difference. The main problems are leakage in through the motor shaft and butane dissolving the tubing... I'm trying to find a type of flexible tube that is butane proof.

@@nielsdaemenI did work in industry. I would suggest finding some tubing made out of PTFE (teflon), it is impervious to most chemicals.

R-600a is isobutane; R-290 is propane... [your in refrigeration?? everybody makes typos... just correcting info, not criticizing.]

In the center, out the side. The cold coil is after expansion

@@justfellover thank for the answer. 👍👍👍

That is how they would be configured in a dehumidifier; only the other way around ~ warm-humid air pass’s though the cold evaporator where the humidity condenses out of the air and it turns cold > it passes through the hot condenser cooling it and a fan sucks the air out

I can.@davidsmith3302

Looks like a windshield washer fluid pump from an automotive parts store

No it's not gear pump, it's just a simple mini air/gas compressor.

I didn’t know anyone made such compressors. Any idea where I can get one?

The pressure and flow requirements are nothing serious. The important thing is that the pump is gas tight. You don't want your flammable refrigerant leaking out the whole time.

I wouldn't panic too much, lot's of commercial fridges use LPG which is just as explosive.

Freon is a name brand not a type of refrigrtant. Butane is a refrigerant so is propane. Weather or not this will work or not I am not sure. I dought it

After a bit of searching, it seems hydro-carbons are VERY common for refrigeration systems. R170 - Ethane, R290 - Propane, R600 - Butane, and many more. As long as there is no oxygen in the system, it should be fine.

He hasnt used it because its fake...

It wouldn't be able to move enough heat.. If it works, it is very inefficient.

@@MadScientist267 I think u may be right, it's why Peltier coolers never took off? But technology does improve with time.

@@lil----lil Yeah that's definitely an efficiency issue there. There isn't much to improve on. There will always be competing forces within something related to Peltier type devices... you have a resistance working completely against the force that is pumping the heat... it spends most of its effort trying to get rid of its own. To get around that, the material will need to be a superconductor, which currently aren't happening at CPU temps... if you've already got the cold temps you need for the superconductor... skip the middle man and use it directly... 🤷‍♂️ Those are useful devices, and can be made to operate rather efficiently (protip: don't drive them so hard, use more of them instead)... but once you start building a serious scheme that has some useful numbers, you're looking at both cost and physical complexity, not to mention real estate to give any stacking room to work. Niche only. This kind of thing, assuming it actually works (the physics are valid, the materials are a different thing, rather dubious)... would fall into the same category.

@@MadScientist267 MadSci: Are you an engineer?

You can hear the pump slow down as the load increases. This is a piston pump or possibly a vane type compressor.

This is actually a diaphragm pump... i honestly am not sure about this. The gas he used would expand and create a lot of pressure that would easily pop those hoses off. Not sure how this was faked, but you wont get much of a adiabatic cycle from silicone hose and a pump thats used for battery powered aquarium air.

@@colinsmith6340 The way it is faked is that you have to keep refilling it with butane because it's just boiling the butane and the pump does nothing

Actually, it only needs to have ~20psi to make this work. More if those temps were real. I think this small diameter tubing could hold that pressure ok. The 'choke' would work if there was no (or little) pressure difference. The restriction only cools as much as the developed pressure difference; so they go hand-in-hand...

@@troubleshooter1975 You wont get 20 psi out of those little pumps. I have one. They aren't compressors, they just use rubber cups to pump air for portable bubblers for things like boats. Bait bubbler etc.

Well, people put small bombs in them ears (Li-Ion batteries in headphones). And also people fart sometimes. People sometimes take showers and trip and die. We live in a dangerous world.

It's not a compressor, just a little pump. Look up mini pump or fish tank pump

I suspect you could also find such a pump inside a dishwasher or washing machine. I know I have saved a few since I have disassembled a few.
