Advice. Consider separating the exhaust and fresh air intake on the outside of the van more. When they are close like yours you will be mixing hot air in with the fresh making it much less efficient.

[@Bellasafari]

Actually doesn’t matter as the intake is on the other side by the cold air out put. (Otherwise the company would suggest separation or the design would be different)

[@whydontyouaskme]

@@Bellasafarilearn to read woman, he’s talking about “the exhaust and fresh air intake on the outside of the van” If the intake is sucking hot air from the exhaust it will be much less efficient.

[@MRL3234]

Mine freezes me out of my Nissan NV 200. We love it. Also. In our small van, we use “sleep mode“, and so the air conditioner only uses about 140 watts!! Awesome. Of course if you’re trying to cool down a bigger space, sleep mode won’t be sufficient. I am in Central Florida. We use it when sleeping at night. It’s awesome. I wouldn’t waste my time trying it during the daytime, I’ve got better things to do, getting outside and doing stuff. I don’t wanna be crammed up in my van during the day

[@deanvillegas]

ADVICE: Use a drip pan with the Zero Breeze. Water does leak from the unit with movement. I use a plastic lid from a storage bin - works great.

[@isaiahrbrown4722]

Keep an eye on the duct tape, it tends to dry out in HVAC applications, I would consider swapping it for foil tape

You can connect the condensation water tube to a water tank and use the water. Or even connect to a Berkey water filter system and use as drinking water.

It's about as expensive as buying the batteries and solar setup for a full size ac unit. $800.00. $1200 full solar 24v-48v system you could build yourself and that cost is including the a.c. unit too. Easly get 5-7 hours per full charge using a 5000 btu a.c. js.

[@mikefranks4528]

@David D you are so correct. The expectation should just be for cooling a person off as direct cooling for like when you sleep as during the day you're going to be out and about and using someone else's A/C as a van lifer (Planet Fitness, Wegmans, etc). For me personally I will have a MideaU project coming up so can't wait to get that rolling and vlog about it.

Genius! Saw your build on Jarrod Tocci’s channel.

[@hohohohehehe6910]

Heat rises and the cold air sinks, so for better results the ac should be as high as you can place it. Also you should give as much room around the vents as possible to allow good air flow. This set up is less reliable and will take longer to cool the van and use more energy.

[@nicholasfisher2729]

Hey I’m a trucker. I think this will be perfect for me. I have a 3000 watt pure sine inverter hooked to battery bank of truck with 4/0 copper cables. Fuse 200amp on battery side and 200 amp(anl) on inverter side. Do you sell basic package( no battery). My truck has an opti idle system, to where if it senses low voltage it kicks the truck on to prevent low battery voltage, so I think this will definitely help me during hot summer nights in Texas when I don’t want to idle the truck all the time for a/c. What do you think? Thanks

[@4Tomorrow1]

Should you separate the in and out airlets further apart? Hot air will go back from the inlet.

[@meowzic]

Did these vent covers just have a mesh fly filter or an air filter? I can't seem to find any with an air filter unless you made your own..

[@carperdiem8754]

I found a roof mount 7800 btu 24v AC on ebay for $600. I know it is a gamble, but we will see how it goes. Draws about 300w on low and 900w on high so battery bank needs to be beefy. This little unit should be great for spot cooling in hot humid areas and good for general cooling in drier climates.

[@Douglas.Kennedy]

being totally portable with a battery pack is kind of neat too.

Can you make a video about how you made that bed that raises and lowers from the ceiling in your collaboration video ? And maybe explain how you did the whole van ?

[@bobclarke2242]

Great product. Did I overlook the unconditioned air supply port thru the box the unit is installed in?

[@erichutchinson1125]

flex is your worst enemy for efficient air movement.. flex creates so much resistance for normal air handlers nevermind a micro Air Conditioner... to make matters worse you aren't even running the full size diameter of the outlet and choked it down to 3". Installing some solid duct.. even PVC pipe will reduce the static pressure and allow the tiny fan to more fully output its rated cfm.

[@mikefranks4528]

I couldn't agree with you on this more. It is so important to have a smooth pipe and less bends to mitigate resistance. It will make a huuuuge difference in performance. You can even test it out with a temp gun and/or anemometer to see the results.

[@caseycook738]

The newly released Ecoflow DC 4K BTU looks compelling for van builds. Maybe next build you can test out one of these units.

[@MadMaxSHTF]

The only problem is that Ecoflow make it where you can't use other power supply/station other than Ecoflow brand. We just need to figure out how to tweak it in order to use other power alternatives.

[@williamgrissom9022]

Need a big battery bank. My Hi-Lo camping trailer has just a single 12 VDC battery ~50 A-hr capacity, so the compressor could only run for 2 hours. I haven't mounted a roof AC, though wired for it (120 VAC outside connector) since few state park sites in CA have electrical hookup, and those that do cost $55/night w/ 1 yr waiting list. I'm thinking of a 120 VAC portable AC (like restaurants use) when needed, but usually camp only in areas which get cool at night.

[@joshuahopton3299]

How much solar can you comfortably run this system without depleting your battery power? I have 300watts of solar and work a job where I have to leave the van for a couple hours. My goal is to keep the van around 75 degrees in the summer heat to keep my dog cool while I’m away.

[@donnieshepperson126]

I've only seen one system work(little Debbie van) he had a generator bolted down on the rear step bumper, and a 10,000 btu window unit placed in front(hole cut out)kept him cool, and his snacks! All these other systems are built just to blow on you, keep you cool by blowing on you. How do I know, I've tried just about everything myself!

How do you turn it on or off,,, remote works? Is it enough to cool off the van during the summer? Having electric wire work and punching holes on the van is a commitment, then it would be better to install permanent AC rather than this portable. I have portable which I could just bring it up to the front seat and have exhaust and intake ducts facing outside the window, it works great every time and won't take any space.

[@alexfarshey6768]

You mentioned the two ports on the back are one for air intake and the other to exhaust heat… Instead of having them both out do you think The air intake port can be channelled inside the van to act as a recirculating air?

[@blairpomeroy3302]

you would then be blowing cold air from inside to the outside, lowering the efficiency, its a 2 part unit, when cooling the inside it draws air from the inside to the front, cools it, then blows it back inside, the heat then goes to the rear of the unit, draws air from outside, heats it, then blows the heat outside.

[@ytJnC]

I wonder if it could work better if the unit was taken apart so that the compressor could be more thermally isolated from the evaporator. In other words, turning it into a micro mini-split.

[@blairpomeroy3302]

@@ytJnC you could easily add insulation around the rear to stop any of the heat from radiating into the inside, but pulling it to bits probably won't work out, I could be wrong though, I'm not an expert, but it would probably be like dismantling a fridge and extending it so it throws the heat outside rather than to the rear, I wouldn't mess with the gas inside it myself.

[@04dram04]

How can it possibly "suck heat out of the van" if both the intake and exhaust are outside the van?

[@MakeEverything]

I’m definitely gonna check one of these out for my modular conversion I’m doing. A note about that duct coming out of the unit providing your air, that harsh 180 degree turn might hurt your airflow and efficiency. When running dust collection piping even a 90 degree kills your airflow so I’d think a similar principal applies here. Awesome to see this unit setup in a permanent way like this!!

Ok .. I watch a lot of these videos & have started to be kinda critical. I have a 10,000 btu window air conditioning unit with a compressor that runs on 120volt ac and have installed it in a mini van to test its ability to cool the van. Even with that unit I had to put a pop up tent over the van and black out the windshield to get my daytime temperature to be acceptable. Night time was more easier for the unit as the radiant heat from the sun was no longer a factor. The unit featured in this video claims to be a quarter of the btu and never mentions a compressor... see how light it is when he picks it up? I’m willing to wager this is a peltier device. A simple internet search will show you how they work. If you are serious about van life this unit may not give you the desired effect.

Seems a bit strange that the hot air output and the cold air input is side by side like that.

[@ytJnC]

I think it’s that way due to the packaging of the hardware, but you are correct. It’s important to have separation between the input/output. It’s one of the reasons why this unit doesn’t do so well in non ducted demos. Ideally the ports on the outside need to have more separation but perhaps the proximity to the wall prevented routing the ducts.

[@peelingpedaler3635]

It was a poor decision to install the ducting right on the metal body panel. This panel will absorb energy radiated from the sun, heat up, and heat your cool air moving through the duct. It would be better to install the entire unit and ducting all within the insulation of the van. Additionally, the intake is on the floor of the van, where the air is coolest. It would have been better to install the unit up high so the hottest air in the van can hit the evaporator. And the ducting you installed would be shorter, increasing airflow.

There are van builds on youtube where they put a stock window air conditioner in by building a false wall across the back (pushing the bed or seating area forward enough) of the van and having the "outside" hot air exchange be in the "garage" area of the van by the back doors. If I did that, I would install something like a PC fan to circulate the hot air out of that space by using some 4" PVC up to the ceiling area to pull out the hottest air, and vent it out the floor. So then you just need enough power to run the AC...

[@mrmotofy]

@@brianmi40 It would generally require a lot more air movement than that. Essentially the venting needs to be close to the square inches of venting on the case otherwise the heat transfer can't work properly to dissipate the heat created. It's sort of like running a marathon while breathing through a straw, just not enough air movement

[@jah-jah87]

The air intake is too close to the hot air exhaust, rather inefficient...
