This is good for proof of concept for refrigeration loops, but not for practical application. With exception maybe to cool a drink can, or a mini water cooler, if the coil was wrapped and bonded to a metal cup or vessel to cool and dispense liquid. For a next version, you could try to put this system through a couple heat exchangers on both hot and cold sides for use with an actual refrigerator or air conditioner. maybe even building this into the lid of an ice chest to see how fast, and cool it can get the contents. Showing what the power draw of the set up would also be useful.

[@AlecKristi]

This "invention" was first created in 1856 by James Harrison... I too experiment with building different refrigeration loops, but I don't call them "inventions", as it's almost 2 centuries too late for that.

[@sonoancoralbar]

in a earlier video he mentioned that.

[@NwoDispatcher]

anytime you build one on your own, its an invention. I hate the learned helplessness of consumerism.

[@EboregOnhzna]

Purge the line used to charge the system with refrigerant before and during inserting it into the system so as not to introduce moisture/air in system.

[@kenbaird6835]

Question: what is the power consumption of your system? I could imagine it being used for compact refrigeration systems for a van/boat, but the efficiency is quite important.

[@confusingx3]

What kind of compressor is this ? For me it looks like a membran conpressor ?!

[@mikeconnery4652]

Well done. Beautiful build, and great explinations.

[@ginoparadiso3539]

Beutiful build. Can you share all te BOM list. Like which type compressor and which tpe coolant you use. Regards.

ele nao vai falar porque nao funciona dessa forma, estes tipos de "compressores" bombinha de aquario nao exerce pressao suficiente para comprimir um gas por varios detalhes tecnicos, mas quem sabe ele cria coragem e coloca algo inovador ae para nós, tudo é possivel mas que é fake é, por enquanto ate que me prove ao contrario ate porque algo que ira mudar a insdustria de forma tao agressiva e facil ninguem posta como fazer e sim faz igual patenteia e vende o projeto

[@ulbuilder]

Look for: mini dc ac compressor You can buy similar things as kits or pre-assembled or buy individual parts

[@advancednutritioninc908]

Nice Work!! I wonder how long the hot side will hold up with the orange tubing connections? I would use copper on the hot side.

[@sreejithns4672]

Which model compressor is using?

[@franzfoneboneaviation4017]

I think the alternating freezing and melting is due to the refrigerant reaches above its critical point in the condenser, thus it reaches the evaporator as hot gas. Also as someone suggested make sure the inlet to the capillary tubes are at the bottom to ensure it’s liquid refrigerant entering the tube

[@leebonnifield6868]

I think in good operation there is no liquid refrigerant entering the capillary tubes, it is gas coming in from the top of the capsule, and it condenses to liquid before it reaches the evaporator.

[@franzfoneboneaviation4017]

@ you don’t want gas in the capillary tube. Ideally only liquid, but that is very difficult to obtain, except under one set of operation in terms of temperatures. Further down the capillary tube you will see flashgas bubbles forming as result of heat exchange ….typically just before it enters the evaporator pressure drop and thus expanding refrigerant.

[@leebonnifield6868]

@@franzfoneboneaviation4017 The inlet to each capillary tube is not at the bottom of the capsule, but surely there is no liquid at the bottom, that's where the hot compressor gas is coming in. I see it's good to have a capillary full of liquid (except before the top bend, where it might drip back into the capsule.) If the vertical capsules don't do enough cooling (I'm guessing that's a problem here) then hot gas will enter the top of the capillary and the first section of the capillary must function as more condenser. At some point downhill along the capillary it is full of liquid which finally starts bubbling as it enters the evaporator. I'm guessing the optimum length of the capillary is 10 times longer than the system we see because the capsules don't do enough cooling. So to fill the last section of the capillary with liquid, some condensation must be done in the first section of the capillary.

[@leebonnifield6868]

@@franzfoneboneaviation4017 I wrote "There is no excessive cooling" but further cooling beyond what is needed to RELIABLY deliver liquid to the evaporator is maybe excessive. I agree with franzfoneboneaviation4017 letting the gas/liquid level in the capillary get too close to the evaporator risks hot gas getting in to evaporator, melting the frost. So reliability is improved by keeping more liquid in the capillary than the bare minimum. That requires more electrical power to the compressor but it improves reliability so no gas enters the evaporator over a broader range of conditions. Adding a control that turns off the compressor when there's plenty of liquid in the capillaries would save electricity.

[@leebonnifield6868]

I think the melting is due to the refrigerant staying above its boiling point in the condenser, thus it reaches the evaporator as hot gas. At 8:40 as he pulls the capillary out of the dessicant capsule we can see that the capillary is not long enough inside the capsule to reach the bottom the way he runs it. I think he should turn it over so the capillary tubes are at the bottom, like you said.

[@CreatorTips.007]

This is an incredibly useful video! The tutorial on making a capsule heat pump is detailed and well-explained, making it easy to understand even for beginners. I’m impressed by how this setup can save money and provide efficient heating in extreme temperatures. Thank you for sharing such a practical and cost-effective solution - this knowledge will definitely help a lot of people!

[@leebonnifield6868]

We can't tell if it saves money without knowing how much electricity the compressor uses. It doesn't save any money on heating (compared to a simple resistance electric heater using the same amount of electricity) unless the evaporator coil is outside the space you're trying to heat. If you're trying to cool the space, only the evaporator is inside, the compressor and the dessicant tubes and capillary tubes are outside, heating the outside air.

[@robertslawinsky295]

if you maximized for moister collection and cycle so that if freeze it then melts as a water collecting devise that can work in some application

[@Wakgendut-ze6nb]

Wow.. This is an amazing job.. I need one for my extracting leafs.. And how's I have one? It's good for extract the leaf in home scale.. I apreciate for your invention..

[@hoberulloa3276]

Hi my friénd, Excellent video, thank you for uploading this type of teachings because they open the imagination to create!! I would like to know how to obtain the mini compressor and the names of the materials, I am from Colombia and I am interested in learning more about this topic, thank you very much!!

[@exbm]

you could add a little more refer to get rid of the frost ice insolates and reduces efficiency

[@퍼머넌스]

Where can I buy a compressor?

[@RaulGraciaFerrer]

Hola , me encanta . Cuanta carga de gas y qué tipo de gas introduces en el sistema ? Gracias

[@ikuminarafernandez8868]

Donde compraste la bomba de gas refrigerante ? Por favor , o que modelo es??

[@LMde20]

Perhaps a thermostat, for control. Btw, I know they were high pressure, but are those high temperature hoses too? The condenser coil, or whatever it is, is sitting on the orange hose. Hate to see it eventually melt and combust the gas, that's why I'm asking.

[@romanursuhack]

The specifications for the high-pressure hoses indicate an operating temperature of around 60°C, but this is not their limit. I have personally tested them even under open flames, and they performed exceptionally well. This is a high-quality product that, despite the listed 60°C in the technical data, can withstand both higher temperatures and much lower ones. You can find more details by following my link to the JLCMC website jlcmc.com/?from=RUHNOV1 . For the thermostat to work properly and be integrated into the system, the pipeline length must be at least 3 meters. Otherwise, the gas will not have enough time to transition from a gaseous to a liquid state, which can result in the system malfunctioning or operating as if there were no thermostat at all. If you notice significant temperature fluctuations, it may indicate a pipeline that is too short or an insufficient amount of refrigerant.

[@LMde20]

@R.U.H. thank you.🙂 very helpful.

[@Lorenzowade101]

Can you recommend any books for small projects like this?

[@thepvporg]

I would try differing amounts of refrigerant in the heat pump, then track what amount vs hot and cold side temperatures. My car's AC takes about 150g of refrigerant as it is determined by the design to be the optimal amount that allows for leaks over time. I would then look at different ways of extracting that thermal energy to be utilised effectively (in this scenario or POC)

[@paulmurphy3838]

Could the hot side be incorporated into a hot water tank, thus also enabling gas phase change. The temperature fluctuations seem to make it a bit unstable if you want constant and even hot and cold temperatures. The distance between hot and cold components needs to be cavity brick length, hopefully that wont be a problem. But, magic construction and design, top marks.

[@danielbornaz]

Would this be enough for a DIY freeze-dryer with a 2-3l capacity?

[@ikuminarafernandez8868]

Hacer un serpentín para la zona de +55° con un intercambiador para agua caliente y calefacción , y un intercambiador para frío (refrigerador y aire acondicionado ) , ese es mi proyecto , gracias por tu aportación y tú trabajo

[@Labor2B]

Thank you for the Video. May i ask a maybe silly question? A hest pump is compressing the cooling medium, this needs energy. The valve which releases the pressure can replaced by a Turbine, to get back the energy, World it work to make it more efficient? Or would it only prevent of release the energy as heat? Btw: what kind of cooling fluid are you using?

[@leebonnifield6868]

> The valve which releases the pressure can replaced by a Turbine, to get back the energy, That valve is opened to suck out the air during construction, and opened to let refrigerant from the can fill the system. Then it is closed forever. If you replace it with a turbine the only energy the turbine will extract comes from whatever pressure was in the refrigerant can. Then all the refrigerant in the system will blow out thru the turbine and be replaced in the system by air, which is a poor refrigerant. So the heat pump function will stop as soon as the valve is not closed.

[@Labor2B]

@@leebonnifield6868 I don't mean the filling valve. I'm talking about the valve (maybe it is not calling a valve) which is seperating the high temperature/pressure area from the low temperature/pressure area. (Pressure reducing valve).

[@leebonnifield6868]

@@Labor2B That's where the 3 capillary tubes empty into the larger diameter evaporator coil. Ideally liquid refrigerant enters the evaporator and then it boils. The liquid/gas boundary moves, depending on how well the system is working, so a turbine there might have to deal with liquid or gas. Yes it would spin and it could extract a tiny amount of power. But at least that much more power would have to be added to the compressor since it is the suction of the compressor that is causing that pressure difference that would spin the turbine. The friction and power output of the turbine would reduce the effectiveness of the compressor. We need to know what refrigerant, how many grams of it, volume inside the system, and pressure with the compressor off. And of course we don't know how much electric power the compressor uses. If a simple pipe with a restriction (or a turbine) has air flowing thru it because it is connected from the outlet of a compressor directly to the compressor inlet, the pipe will get hot between compressor output and restriction, and it will cool between restriction and compressor input. But not much, because air does not liquefy/boil at appropriate temperatures and pressure. With a well designed system (it needs a precise amount of refrigerant for its volume) the air temperature outside the condenser (the dessicant tubes) is low enough for the hot refrigerant gas to condense, and the air outside the evaporator is hot enough so the cold refrigerant liquid boils. The phase change in both directions (condensing and boiling) moves MUCH more heat than the temperature change. Also I'm pretty sure the video shows the machine operating upside down, the condensing liquid should drip down and flow out the BOTTOM of the vertical dessicant tubes.

[@yiinyaan]

Is it possible to make it reversible?

[@leebonnifield6868]

If you want hot air blowing into your room, you put the evaporator outside and use a fan to blow room air over the condenser. If you want cold air blowing into your room, you put the condenser outside and blow room air over the evaporator. Instead of reversing the wall mounting or modifying the system, think of a cabinet for the stationary heat pump, with moving ducts so you can choose which component blows into the room while the other blows outside.

[@patiphansingkwang675]

You did a great job (I'm not stupid)

[@JeongJaeWoo]

You should have posted a list of the supplies you used for the company you are sponsoring. Wouldn't that be true advertising? Also, would the method of cooling the evaporator by dripping water increase energy efficiency?

[@leebonnifield6868]

Dripping water on the condenser would cool it better than still air at the same temperature. Putting the condenser under same temperature water would cool it even faster. Flowing cold water over the condenser, better yet. You don't want to cool the evaporator, it cools you, you heat it. The evaporator is the large diameter coil with frost. The condenser is the 4 dessicant tubes, the horizontal one is the hottest. I think the video shows it being operated upside down. If it were turned over so the horizontal dessicant tube were on top then as the hot refrigerant gas enters the condenser and is cooled and condenses it would trickle down thru the vertical dessicant tubes and exit as liquid into the capillaries at the BOTTOM of the condenser.

[@Waldemar_Pachol_official]

And that's how it is when refrigeration is taken on by people who have no idea about the processes that occur during compression/expansion, the formula PV=nRt, or the correct superheat/subcooling value. The tubes are freezing so it works - well, nothing could be further from the truth!

[@jeanbastien8690]

Tu aurais du faire ton condenseur comme ton évaporateur et plus gros

[@EboregOnhzna]

Your design has got me stumped. The short stub out from the compressor looks to me to be the output/high pressure side and the long one vise-versa . The orange tube goes to the in/low side of the compressor and the blue tube goes to the out/high side. The orange tube then goes to the hot/condenser and the blue to the cold/evaporator. Is this not the opposite of how it should be ? Obviously it works so where am I wrong ?

[@leebonnifield6868]

At 16:31 he's connecting the orange tube to the evaporator. The evaporator must be connected to the suction side of the compressor. At 16:35 the orange tube (pressure) is going to the horizontal dessicant tube, the condenser. At 16:42 it's clear the blue tube (suction) is connected to the evaporator. I think he's holding it upside down, the capillaries should be on the bottom.

[@ghlscitel6714]

I don't understand how it works. Is this a Joule Thomson heat pump? where can I read more about this?

[@jonbulau5963]

[@asoc1088]

Turn it upside down, so liquid refrigerant can flow into cappilary tubes.

[@leebonnifield6868]

Я видел ребята из Юго-восточной Азии делали что то подобное, но там был монтаж и просто показывали видео задом наперед, якобы за кадром замораживали змеевик и показывали как он оттаивает, а на видео из за монтажа был якобы процесс замерзания. Это из той серии где к двигателю подключают генератор и потом от генератора запитывают электро двигатель и получается вечный двигатель. Поэтому очень скептически отношусь к таким малым системам охлаждения. Но в вашем видео скорее всего рабочая модель, т.к. все сделано теоретически правильно.

This guy’s mechanical skills… Should have used a torch, rather than a soldering iron: The copper wasn’t heated enough to properly bond the metal, and I’m pretty sure the device will leak within days, if not right away. I’m guessing this is just a commercial for JLCMC. Viewers get excited, buy the parts, and build this clumsy prototype thinking they’ll have a cheap A/C. Guys, it’s a cute way to practice and learn basic concepts, but it’s not gonna be cheap nor potent enough to be useful. There are already better ways to cool an ice chest.

[@_-JohnDoe-_]

It is obvious that the heating elements need to be equipped with radiators and add another fan to them, otherwise the temperature difference will be reduced (this indicator also depends on the brand of the refrigerant). Next, both arms should be equipped with temperature sensors capable of controlling the on/off of the compressor motor (but not the fans!). The current scale is a toy. It is necessary to provide the possibility of scaling - to the size of household use.
