Can you make a water dispenser with hot and cold water using your heat pump?

[@ТимаКама]

WATER FROM THE AIR Hello. Try to make a device for collecting water-condensate (water from the air), i.e. the cooled part of the refrigerator (or expand the area for snow-condensate with metal plates) the cold part with frost (snow) on the metal (metal plates) cools down, builds up snow after some time the valve with warm air or water switches and is supplied to the snow and washes away the condensate (snow) - thus it will receive water from the air (very cheap and can be used in the desert). As options for heating snow - heating from a turbine - induction heating - heating in a box through glass in the sun - magnifying (reducing) lens and heat with a beam, a direct beam or heating a stone in water ВОДА ИЗ ВОЗДУХА Привет. Попробуй сделать установку по сбору воды-конденсата (вода из воздуха), т.е. охлажденная часть холодильника (или расширить металлическими плитами площадь под снег-конденсат) холодная часть с инеем (снег) на металле (металлическими плитами) охлаждается, наращивает снег по истечению какого времени переключается клапан с теплым воздухом или водой и подается на снег и смывает конденсат (снег) - таким образом будет получать воду из воздуха (очень дешево и можно использовать в пустыне). Как варианты нагрева снега - нагрев от турбины - индукционный нагрев - нагрев в коробке через стекло на солнце - увеличительная (уменьшительная) линза и лучом разогревать , прямым лучом или нагрев камня в воде

You can buy an old refrigerator case from the 1950s and redesign its cooling system. It is made of steel with a thickness of 2 mm and painted by completely dipping into a bath of paint (3 times). This is a very, very stylish design and it will never rust, unlike modern products. While verbally supporting the care of nature, the producers force us to change the equipment every few years - and such an old refrigerator has been working for 50+ years and longer!

Look mom! I built a refrigerator out of refrigerator parts!

[@이윤수-k7w]

This is an interesting video. I'm not sure what refrigerant is being used in this refrigeration cycle, but I don't see a typical condenser. Generally, a refrigeration cycle without a condenser cannot maintain thermal equilibrium, and if it continues to operate, the cooling effect will disappear. Therefore in this video, it seems that a very small amount of refrigerant is being adjusted to flow through the piping between the compressor and the capillary tube, allowing it to function like a condenser

[@davegeorge7094]

It's insults your intelligence, yes?

[@lpqlbdllbdlpql]

It's essentially cooling and heating the same air so yeah

[@biglew1161]

based on limited knowledge of the refrigeration cycle, and not knowing flow direction of the compressor, it looks like the refrigerant is getting compressed (condensed) into the coils on the fan, and evaporating into the expansion tube device. so to me it looks like this is operating backwards. but it does look like it works. put the compressor between the coils on the fan and some more coils before the expansion tube, I think it would be almost a complete ac

[@briansmyla8696]

The refrigerant is most likely butane.

[@onemischiefmaker7032]

@@briansmyla8696 YES and it did not shown getting a vacuum pulled either.. The basic bomb!!!

[@SSM20985]

Butane liquefies at 30°C under a pressure of 3.8 bar. If the return gas from the evaporator is below 30°C, this pressure can also decrease. Therefore, the pump must be specifically designed for gas, and its minimum compression pressure should be 4 bar for it to be feasible. Additionally, if possible, please use a pressure gauge in your videos to make it more credible

This guys knowledge of thermodynamics is obviously brilliant, insomuch as he has disproved so many well established laws of thermodynamics.

[@JD_Mortal]

Not sure why the return is restricted and extended... You want that cold excess to return to the pump, to cool it down. If anything have it fork to the hot supply, before the valve, so it gets super cooled. If the valve was temperature controlled, you can stop it from freezing, reducing pump stress and get super efficiency output that matches demand. Freezing over actually means there is not enough coolant in the unit. That is why home units die. The temps get cold enough to create insulating frost and also freeze up the freon, clogging the lines and killing the compressor that can't compress liquids or frozen solids.

so this system is simply using the presure change of a can of butane to cool its not a heat pump at all yhe small tube creates the preasure change but when the tank is empty its done

[@BurkenProductions]

Ok? So how does it work? Would be nice with some explenations!

[@TheStigma]

Same principle as any AC, refrigerator or heat exchanger: A refridgerant gas is compressed (compressor) into a liquid state and passed through capillary tubes (extremely thin, to retain pressure). When this liquid gas enters the evaporation chamber (cold side, like a radiator for example) it sudden has room to expand and the pressure drops drastically causing the liquid to become gas again. This sudden gas expansion absorbs heat from the surroundings - this happens to all gases in general, which is why something simple like sweating can cool you down. The hot gas is passed back to the compressor which forcefully squeezes the gas back into liquid with high pressure. This forces the gas to release all the heat it had absorbed (hot side). The result is that you can use some energy to move heat from one place to another - for example from inside a fridge to the outside (usually back). Or an AC can use fans on either side to move heat inside to outside, or vise versa. ACs are often designed so they can run in reverse also, to provide both heating and cooling capacity. A heat-pump (basically much like an AC) can achieve 350-400% heating efficiency compared to an electric oven which can never be more efficient than 100% - because it is not making the heat itself, but stealing it from the outside. I hope that helps :)

[@valentinloginoff]

​@@TheStigmaso, let's look to the system from video. Parts on wrong place. Compressor made pressure, after must be condesor coil with fan, next thin tube who divide system to high pressure side, and low pressure side. Next part vapor coil/heat exchanger. I have no idea, how system from video can work.

[@TheStigma]

@@valentinloginoff I think several parts that you find in a normal system has been skipped here to make the minimum configuration that works to show the principle. Like the expansion valve is also effectively the condenser here. I suspect the machine is intended as more of a proof of concept/principle than effective functionality - because it would definitely not be practical to cool air. In any case it is a very non-standard setup. I'm not a HVAC engineer, so I can't verify this works 100% - it just looks plausible based on what I do know.

[@valentinloginoff]

​@@TheStigmain frige we have simple AC system based on thin tube. But order of components always is same.

[@TheStigma]

@@valentinloginoff I think technically all you strictly need for a loop to function is the compressor, a space for the gas to expand, and somewhere to dump the excess heat. Everything else is kind of optional. But like I said, this is not my best area of expertise, so it is better to argue this with someone who builds these systems if you want certain answers. It is well over a decade since last I did some DIY with these types of systems.

Mind that working and safe operating are 2 different things. In Europe insurances are kinda picky when operating flammable gas, especially for indoor appliances.

[@TheStigma]

EDIT: I'm inclined to believe this is a fake after seeing that this is apparently a popular thing to fake on youtube for some strange reason. Lots of videos on the same topic that are clearly using airpumps or other things that can't possibly work. Most of them are much more obvious than this, but they are all so similar in format I have to assume this is no different given the very unconventional setup. Nice build. is that a tiny compressor? Never seen that formfactor before. I think you will have problems long term with gas-permeation in all plastic parts and seals, and slowly lose refrigerant. Full-copper construction would solve this, but this is harder to make everything fit. Shouldn't there be a radiator or at least coil on the cold side if the purpose is air conditioning? Or is this just a demonstration of the basic principles? I think a good option to look for in a DIY heatpump is to make a water-chiller. That is the same basic setup, but a plate heat exchanger on the cold side instead of the usual radiator. The cold water can be lead outside via small holes in normal insulated plastic water piping to a big radiator (you can usually source cheap if you look around). Plate exchanger can also be scavenged often..Not as high efficiency as a direct gas-loop, but quite good - and way more flexible in placement, installation and future servicing when you don't have professional tools and parts.

[@TheStigma]

@@sw6188 It is possible to make do without a vacuum. You can purge the existing air with refrigerant, close, then pressurize - assuming you make valves necessary for a purge. This is a bit hacky solution, and if not done exactly right it will impact performance or even cause damage to the compressor over time. The U-bend in the expansion valve is probably there was a part of the adjustment mechanism, providing an alternate more restrictive route when almost closed. This adjustment is usually to tune the system to provide a good balance between more expansion (lower temp) and more flow (higher heat capacity). This looks like a non-standard and truncated system that only has the minimum parts required. Maybe more to show the principle than to be a practical machine. It looks at least plausible to me - but I'm not a HVAC specialist.

[@BangkokBubonaglia]

@@TheStigma Thank you for that. I was trying to figure out the purpose of that U pipe. Your explanation makes sense.

And the condenser does not come after the evaporator, what are you doing RUH?

[@Skunkhunt_42]

Those push connects gonna leak - need square cuts

[@TomasJknOnYT]

Errrr, I think you connected it wrong way. Your condenser needs to be _after_ the compressor, not before. You have compressor->expansion valve(capiliary)->evaporator->"condenser", but you need compressor->condenser->expansion valve->evaporator. Currently your "condenser" - the thick copper coil on top of the fan is doing _nothing_ and your capiliary plays the role of both condenser and expansion valve...

[@Rafael-i1d1q]

I had doubts at first too, but after reviewing it closely, everything is correct. The system follows the proper sequence: compressor -> condenser -> expansion valve -> evaporator. The thick copper coil on the fan is the condenser, and it's working as it should by cooling and condensing the gas. The capillary tube acts as the expansion valve, lowering the pressure before the evaporator. So, everything is connected correctly!

[@TomasJknOnYT]

​@@Rafael-i1d1q Look at @10:16 capillary is between the compressor and the thick copper cylinder (which must be evaporator as it gets cold - judging by the frost on it). So we have compressor -> capillary (whatever role it plays) -> evaporator. So your statements above are _contradictory_. On one hand you say "The system follows the proper sequence: compressor -> condenser -> expansion valve -> evaporator" and then you say "The capillary tube acts as the expansion valve" implying that capillary is between _condenser_ and _evaporator_; which is directly refuted by the image @10:16, which shows capillary between _compressor_ and _evaporator_

[@Rafael-i1d1q]

@@TomasJknOnYT Let me clarify things in more detail to clear up any misunderstandings. At @10:16 in the video, it's true that the capillary tube is placed after the compressor and, as you correctly pointed out, is connected to the evaporator. However, I was initially referring to the standard operating sequence of such systems, not specifically the setup shown in the video. As for the specific system in the video, there’s a unique configuration that may not be immediately obvious. In this case, condensation could occur through a non-standard setup where the capillary tube manages the flow of refrigerant rather than serving as a traditional condenser in the usual sequence. So yes, this isn't a conventional setup, but the system is functioning properly in its own configuration. It might operate differently from standard examples, which is where the confusion arises.
