All the Technology Connections subscribers say it with me now: HEAT PUMP!

[KuntalGhosh]

They have fitted all the parts of a regular inverter heatpump into this.
Twin rotary compressor, reversing valve , electronic expansion valve. Veriable frequency drive.
Definitely one of the most advanced portable aircons i have ever seen.

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.

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.

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

[akhtarkh]

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.

For the curious - BTU= British thermal unit. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit 🙂

[arh]

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.

[iamconio]

how good must a product be that the company has the confidence to SPONSOR a TEAR DOWN video of their product ?!? amazing

[tcwNZ]

Seeing those two heat exchangers on opposite sides of the box is actually comedic, solid temperature differential you've got there

[Levi_Holiday]

You look amazing with your hair blowing in the wind. 😂

[nateswain]

This is cool. I wish Ecoflow made 2 part version of this unit connected with hoses for vans buses and RVs. Like a mini mini split. It would be way more mini compared to some much larger versions on the market currently.

[neiguerrameira]

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.

[npsit]

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.

[southaussiegarbo]

BTU is short for British Thermal Unit, a unit of measurement that shows just how much energy your air conditioner uses to remove heat from your home within an hour

[PWL]

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.

[Nico-zdyr]

isn't this just a window ac with a battery?

[drbelieve]

Even without an open flame, it could catch fire. It has a humongous battery on the bottom of it. Especially if it gets hot.

[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.

[waltundres]

Looks like a cool unit! I think it might be a good idea to add a second duct to the intake, so you are not creating a vacuum inside the space you want to cool/heat and therefore suck outside air back into the space through doors/cracks etc.
