When I taught refrigeration, I placed a small compressor (salvaged from a window AC unit) on my desk. I took a roll of 3/8" copper tubing and brazed one end in the compressor discharge port. I unrolled the copper and made a big circle around all the student's work tables and brought the other end back to the compressor suction inlet. I evacuated the air and put several ounces of R22 in the loop. Just a compressor and a big circle of copper. I started the compressor and had all my students feel the copper tubing as the compressor ran. They all agreed, nothing was happening. The refrigerant may have been circulating, but there was no change in temperature any where. Then I had a volunteer student take a hammer, and standing on the other side of the copper circle, begin slowly, gently, hammering the copper tubing closed. As he tapped the copper closed, I had all the students feel the copper on both sides of the copper being hammered. Nothing happened at first. Then, suddenly, the restriction was just right and ice began to form on one side of the crushed copper, while the other side got warmer. We had built a very basic refrigeration circuit. I explained to them that we can add lots of bells and whistles to improve effectiveness and efficiency, but this is the basic circuit. They watched in awe, then I told the hammer volunteer to smash the copper closed. As he did, the refrigeration stopped. I told my students, you've now just witnessed a blocked restrictor, so you'll know it when you see it again. Simple but effective lesson.

It's worth noting that as far as modern heat pumps are concerned, 200% efficiency is actually quite terrible. The more accurate term to use is COP - coefficient of performance, where 1.0 means that the heat moved is equal to the additional energy cost. A higher COP is better. This unit would then have a COP of 2.0. modern heat pumps typically have a COP ranging from 4.0 on the low end and 20.0 on the high end.

[@arh26884]

The refrigerant called R290 is simply the flammable fluid Propane jejej, but with a small charge it is a perfect natural refrigerant with almost zero ODP and GWP. Another correction, the 4-way valve only reverse the direction of flow, so the evaporator becomes a condenser and vice versa, but it does not make any type of compression, the only part in the cycle responsible of compression is the compressor. The part responsible of the expansion is the thermostatic expansion valve between the condenser and evaporator.

[@xFluing]

Thing is, for a heat pump like this to be 200% efficiet you would need to have the condenser and evaporator completely separate (one exclusively outside, the other exclusively inside) no matter which is which (the evaporator becomes a condenser when in heating mode). This is regardless of venting the air outside, there still needs to be a temperature difference between the two to keep its efficiency

[@architypitect]

More specifically, it's most efficient to have a heat exchanger outside because warming (or cooling) inside air you just cooled (or warmed) and pushing it outside not only wastes some of your effort, but also creates a vacuum inside that draws in outside air that much faster.

[@eduardobarros2958]

Well, i think the 200% efficiency claim is counting with the condenser and evaporator close to each other, because bigger heatpumps with the units split between outside and inside can reach efficiency of more than 400%

[@omniyambot9876]

That's why there is an air hose as it absorbs heat from the outside. It will work like a normal heater at 100% efficiency cif you just cool down the room at the same time.

[@xFluing]

@@eduardobarros2958 its not about distance, its about separation. A heat pump to truly be efficient needs to have the condenser and evaporator physically on different sides of the building, one in one out.

It is an interesting product, probably more useful for RV living. But, 200% efficiency, which is a CoP of 2 is not impressive in heat-pump technology. Currently home Heat pump CoP is reaching 4, which is 400%. You would also need to connect two hoses, one to bring the air in to pass over condenser/evaporator and the other to take that air out. BTW, R290 refrigerant is pure propane and is a good refrigerant, used extensively in Europe but in N. America an unnecessary hype is created about its safety , perhaps to safeguard the commercial interests of CFC refrigerant manufacturers.

If this is used indoors, the air that is expelled outside has to be replaced from somewhere, which is outside the room and so the aircon has to continually labour to keep the temperature to where you have set it. Doesn’t sound too efficient to me.

[@DarkBloodyFoxy]

You are absolutely correct. Also, compressor gets hot by itself and it stays in the room lowering the performance of cooling operation. And those are pretty common issues of any portable/mobile AC units. Split ACs are better but stationary (and much less noisy since everything happens outside).

[@neiguerrameira7333]

Just ONCE I'd like to see one of these "standalone" A/C units have both an intake and exhaust for the condenser coil's airflow. ALL These style devices exhaust the same air you're trying to cool/heat, which causes a pressure differential making the climate controlled space draw in outside air.

Oh yes please. Doesn't make sense to cooldown a room while the vacuum it's creating pulling in all the hot air. So overall efficiency is pretty terrible

[@AquaTech225]

What vacuum. The condenser is capable of pulling outside air over the condenser and exhaust back to the outside. A the evap is pulling air from the inside over the coil an pumping it back to the room. I mean if you set it up outside to blow in. Than your cooling outside pushing in creating a positive pressure. Otherwise you do as stated above an it’s not a positive or negative it’s just circulating. With the Wave 2.

[@npsit1]

So the coil that gets hot is going to be the condenser. The side that gets cold is going to be the evaporator. The refrigerant goes through an expansion valve which lowers causes the pressure to drop and therefore the refrigerant gets cold before going into the pump to get compressed, cooled, evaporated, condensed, and start over again.

[@jw3843]

I think you got it. Basic heat pump Air conditioner. Main parts are a compressor, evaporator, condenser, metering device, and reversing valve. Compressor, compresses the hot gas, pushes it through the condenser to condense the gas to a liquid giving off heat, goes through the metering device, flashing liquid into gas and liquid, goes into the evaporator that evaporates it back to a gas giving off cold and goes back to the compressor to get compressed again. Air conditioning 101 in a nut shell. Heat mode reverses the flow of refrigerant, making it give off the heat inside instead of outside.

[@PsiQ]

For the Heating: Please mention that the "heat pump" only works as long as there is enough energy to pump.. commercial air-heat-pump units in central europe usually stop at 5°C because the air/humidity could freeze up in the unit when the energy gets removed. The commercial units usually have a electric heater in the range of 2kW to 5kW for those low temp days, running as heat pump 90% of the time with varying COP. So if its really cold outside you still need some additional heat source. If you use water not outsideair as source you can get a lot more energy out of a water tank, freezing it up in the process.. and then can use that ice block in the summer to cool your house again.

[@TheNone724]

Well there are some air source heat pumps that can even go to -20C at 2 COP but it requires melting function reducing effective COP a bit.

[@locopavolko]

That "4-way valve" is a reversing valve. Two of the tubes on it never change, the one by itself is a discharge line, the one in the middle of the set of three is the suction line. The other two is where refrigerant is directed by the valve depending on whether you're in heat or cool mode.

[@SverigeKodar]

Actually, it's not 200% efficient. As it's not converting the electrical power into heat. It's converting it into movement to transport and increase the density of the heat. It is, however, able to move more units of heat than can be generated by the same amount of power. That is what the COP AND EER value is all about: Coefficient of Performance and Energy Efficiency Ratio Also, the "cool air" is being "ejected" anywhere. As the refrigerant expands, it gets cold. It can then absorb heat from air passing through the condenser. The air on the other side has now lost some of it's energy to the colder condenser and thus has a lower temperature then before passing through it.

[@Dirty_Bear22]

200% transfer efficiency would technically be correct.

[@waltundres9630]

The biggest problem is simply the watts needed, most vans and tiny homes are small so you don't necessarily need the power that most window ACs provide, you can go smaller. Instead of 400 watts something like 200 or even 150 is probably the sweet spot. Which is doable because they make tiny fridges so making a tiny heat pump which is just a reversible tiny AC should be doable. I guess in BTU instead of 4000 btu you could probably get away with like 2000 btu. Thus allowing people to have cold and heat all with solar!!!!! While also being neat, clean, and unobtrusive. Right now people have like wood stoves, propane heaters, diesel heaters, all which take more work and more installation. Having a separate heating and cooling system is just more added complexity and more annoyance. A tiny mini split heat pump would streamline everything. Instead of having to find diesel or propane or sticks, you just have a solar panel that handles everything. I currently have a window AC that runs off solar but it's HARD, that AC eats my solar like nothing, and it's quite simply too powerful for what I need. I can only run it in short bursts because it's too strong. So it goes from being too hot, to too cold, to too hot, to too cold.

I'd be curious to see how this compares with small mini-split units and RV units. I've been looking for a very small AC/heat pump that can ramp down in output for a small van/truck build. Don't want to have a massive unit strapped to the side or something, and the volume is so tiny that even a very small unit would be way too much. I'll keep an eye on this one.

[@duckmelvin7703]

best part it is still flammable. R290 is a propane refrigerant so if there is a leak which should be rare it can catch on fire if there is any flames around.

[@noble_lime]

The efficiency number of 200% goes against electroboom's(free energy)

[@williamtrevena7016]

Okay so it's not as efficient as a normal house air con split system. which are now between 4 and 5 COP in that for every kW of energy consumed they move 4-5kW of energy. I like it but I kinda feel like the reverse cycle component needlessly complicates it. If you make it so that the evap and condenser exhausts are the same you just turn the unit around and put the flexible ducting on the opposite side that you want. It looks pretty well made and is very compact.

The good thing about filming a teardown is, that you can watch your footage to figure out, how to put it back together 😉

[@shubinternet]

So, the advantage of the old style 100% efficient space heaters is that they don't have any waste heat that then needs to be disposed of. Any kind of heat pump is always going to have waste that will have to be eliminated. And in an all-in-one unit like this, that means the efficiency of the unit suffers because you have to have some way to get that waste to wherever you're going to dump it, and that method is not likely to be air tight nor well insulated.

[@downtube8fs]

The waste heat only comes into play if you're trying to cool down a place. The only thing better than this is a diesel heater.

[@jlsrr2577]

Surprised to see r290 (propane) on an indoor residential unit. It is the most efficient. They must use a very small amount and it requires lower compression compared to other refrigerants like r410a or r32

The only problem with these type of AC units is the hot air being pumped out the hose to the outside means it has to pull more air into the room from somewhere, usually outside. This makes it almost impossible to cool a small space like a boat cabin or RV or tent. I have one of those stand up units on wheels where you put the hose out a window. I bought it for my RV when the main AC broke down. The portable AC did not cool the RV at all because it had to pull air in from outside and it was 90 degrees. The unit does however work to cool a bedroom in a house. This unit needs two hoses, one to suck outside air in and one to blow the hot air out.

[@brucejenner2027]

Thanks for the review. I've ordered one to see how this works. In our mild climate in Vancouver I'm just looking for a little extra cooling in the top floor in the summer and a little extra heating in the bottom floor in the winter. This looks like a great option. Installing a complete heat pump system was going to be hugely expensive and only 1/2 the system would be used at any one time in the year.

[@Mahi-trbl07x]

Let us know how it went

[@duckshepherd]

With that duct forcing air out of the space to the outside, that will cause a negative pressure inside the house and make unconditioned outside air infiltrate into the home. This really kills the efficiency of portable AC units like this. The units with two ducts instead of one are the type to get, since they simultaneously intake and exhaust air from outside, leaving the conditioned space pressure neutral.

[@AaronPowellvox]

BTU stands for British Thermal unit. The amount of energy it takes to raise the temperature of one pound of water by one degree Fahrenheit.

The expansion valve is the black piece at the bottom middle at 4:18 with the wires running to it. It is an electronically actuated expansion valve. Further the reversing valve does not further compression in any way rather changes the path that refrigerant is allowed to flow. Fun fact: basically any gas can be used as a refrigerant! R-290 is actually just refrigerant grade propane!

Edit: Hey Zack... apparently you forgot to show us the most important feature of this unit for efficiency. Just ONCE I'd like to see one of these "standalone" A/C units have both an intake and exhaust for the condenser coil's airflow. ALL These style devices exhaust the same air you're trying to cool/heat, which causes a pressure differential making the climate controlled space draw in outside air.

[@pedan21]

There is plenty of them. But they should be mandatory.... They have about dubble the efficensy, compared to this model. a 200% efficensy in a heatpump is kinda bad tbh. A lot of them are about 500% under optimal condition

You need to have an intake and exhaust duct (looks like this has exhaust only?) for proper efficiency. Surprised that a battery-powered unit doesn't try to maximize efficiency. Maybe it is 200% efficient, but most heat pumps are 300-500% efficient. Seems like a battery-operated one would want to be closer to 500% to have any chance of being useful. Definitely need 2 ducts total to have a remote chance of achieving that

It does use 2 ducts. It being small, and not a split system is likely why the COP isn’t great.

[@rafavillasboas]

Every A/C needs two intakes and two outtakes of air. If you have only one outtake, it will use the air inside the room to cool the hot part of the system and will create negative pressure inside the room and therefore will pull ambient temperature air through every gap. So it's not THAT efficient. I've made some modifications on my "portable" A/C to take outside air to cool the hot part and outtakes the hot air without creating negative pressure in the room. The efficiency appeared. I've been living in a camping tent for three years now. I know there is no thermic mass on it but now I have a good ambience inside it.

[@rafavillasboas]

I've just made a quick research on YT and, in fact, ecoflow makes it with two tubes in the window. One intake and one outtake.

[@FerociousPancake888]

[@Milos_adventurediary]

The valve doesn’t compress only expands hence the name expansion valve. One heat exchanger will condense the hot high pressure gas coming from the compressor into a warm high pressure liquid by rejecting heat (this can be used for heating) the liquid then gets expanded through the valve lowering its pressure (and boiling point) the other heat exchanger will then absorb heat (this will be used for cooling) and boil off the low pressure liquid until it is a low pressure gas. This then returns to the compressor to gain heat from the motor and once again increase the pressure. I’m a HVAC engineer in the UK👍🏾

That was probably due to a manufacturing defect, fatigued piping, bad solder joint, or you just pulled the pipe way too hard - otherwise that shouldn't happen. If that does happen watch out because many minifridges use butane and other flammable gasses for refrigerant.

[@coltonfinney7763]

A btu is a measurement of heating or cooling capacity. It takes 1 btu to change 1lb of water 1 degree Fahrenheit. Thats what a btu a based on. The sensing bulb on the suction line is connected to the thermostatic expansion valve which is where the refrigerant(which is essentially propane in your case(r290)) is metered in cooling mode. It appears to have an orfice style metering device for heating mode, which is bypassed in cooling mode, just like the TXV is bypassed in heating mode. Still don’t see where this unit rejects its heat, if it rejects the heat from collected from indoors to indoors as well it’s fighting itself. If you like the heat pump tech; get a split heat pump system installed on your house.

[@fenvesik]

Technically this also has flamable gas inside. R290 is propane. But yeah, much safer and more efficient to use it's phase change energy than to burn it for a little heat...

Hi Zack, love your videos. I want to correct a couple of things you said in the video which are a littel misleading, which I am sure you didn't intended. When you said it has 200% efficiency and compaired it to the electrical element heater having 100%, that's incorrect they are not the same. That's electrical efficeincy of 100% for the electric heater, the AC unit may have somthing around 60% electrical efficiency. The 200% is the heating/cooling capacity, which should be two differnt values one for heating and one for cooling. Basically if you input 1kW of energy, at 200%, it will provide 2kW of heating or cooling, after the energy lose through the compressor, fan and other components. Additionally, the BTU stands for Birtish Thermal Unit, used in many countires as a heating/cooling measurtment unit, funny enouph not used in the UK. 1kW of power is equivalint to about 3400 BTU/per hour. Last thing, I noticed one flaw in the design, there are no filters on the heat exchangers, which will be a big problem. Dust and dirt will accumilate quickly clogging up the fins, reducing their performance, having a filter to clean regularly will significantly reduce dust/dirt accumilating on the heat exchangers.

[@Jay22222]

Something very important to note is that when a business sends a product to a channel like this for review JRE didn’t buy it off the shelf in a store or online. Unscrupulous businesses have the opportunity to hand select every component from the ground up and do 1 off extras knowing its going to be torn down and heavily scrutinised and I think that’s VERY important to keep in the forefront of your mind when watching a video like this or considering a purchase. Knowing What’s inside that box is essentially the shopfront window that the entire world will view your product through and that gives them a HUGE incentive to find or make a unit that is not necessarily representative of a “straight off the production line” unit. This ranges though not simply to scam or outright trick people but it’s fair in my opinion they would want to check that it isn’t a unit at the lower end but just passing quality control, nor the highest end. Rather something in the middle that is representative of the majority of the units sold and we’ve gone from talking dodgy business to the gold standard here but as long as they have a policy that accounts for if that lower end unit that passed QC but was sold and has problems. As long as that’s taken care of

Just to nitpick -- that can of "compressed air" isn't actually compressed air. It's literally a refrigerant, and thus makes your example all the better. The can getting cold is due to that liquid refrigerant inside boiling off and absorbing heat, which is exactly how the cold side of that heat pump works.

Jerry, I love seeing all of your projects! It is now August 2024 and the EPA finally approved R290 (propane) for household use where the charge is limited to 500 grams, if the monobloc compressor keeps all the propane outside. It may take another year for the local and national building codes to agree, although Europe has been using the R290 refrigerant outdoor only for years. I see that this portable unit has a 2 hose design, so I'm assuming the top hose draws in outside air and exhausts any propane leak to the outside. Since this is portable I assume the charge is limited to 150 grams of propane, which has been approved for some time for indoor use. The Inside fan must just recirculate the inside air with no change to pressure (unlike single hose portable AC for the home) which one of your commenters is referring to. He is assuming it draws air from the living space, then exhausting outside, thus creating a negative pressure. I hope not. That is also the way decoration type fireplaces are built in Southern California. The people sitting in front of the fire feel warm although the combustion air is drawn from the leaky windows and doors (cooling down the other rooms). You mention that this unit is twice as efficient as old fashioned resistive heaters. I'll have to do more research into R290 since I heard a range of their efficiency, perhaps they are similar to recent refrigerants (COP of 2 to 4 Coefficient Of Performance, 100% = COP of 1) that still deplete the ozone and their benefit in heating homes in Europe is the ability to attain Higher Heat for water heaters. Where I live in SoCal, Cooling is more important.
