Winner-Winner...Chicken Dinner! I really like this unit. It is self contained and simply requires A/C plumbing and 12 volts and a ground. It will reside quire nicely on the floor behind the passenger seat, up against the battery box. It will take up very little floor space.

Opinions?

Remove the refrigerator and pop this unit in it's place.
You just gained some floor space.

Haha! I think I would gain some storage space too!

That looks very nice. Place in between the front seats and plumb in.

Ya, I'm psyched I found this unit. In between the seats is the other option. My only concern with that is losing the walk through ability. We have two small kids 4 1/2 and 3. Things get dropped on the floor and we, should I say my wife, goes back to tend to them. Stepping up and over this unit would be cumbersome for us.

Is it wrong to think this could be mounted under the bench and ducted to four circular vents? I'm not sure what's required to make that happen power wise. I'll be following this closely. Popcorn

Interesting,
I put the specs into Google and received this conversion:

8116 Kilocalorie/Hour Square Meter = 2992.11805 BTU/Hour Square Foot. Not quite the 5K Terry is suggesting but it's better than nothing.

So you get a compressor, additional crank pulley, mounting bracket and belt and a condenser, plumb it all up to this unit and stay cool? Or is there a 12 volt compressor available as well?

The nostalgic air floor unit that I am leaning towards is rated at 17,000 btu. This should be more than enough to cool the van.

I hadn't thought of this but it a good idea. The unit is 20 inches high, so I don't think it will fit. I kinda like the idea that this unit is completely self contained and stand alone. I really don't like drilling and cutting into the interior, if I can avoid it.

Ahoy,

So, I am not sure what the front intake on the AC Vanagons does compared with water cooled, but do you have a plan to deal with minimizing air infiltration, or internal air recirc in the front? I'd guess that if you have any air coming in while underway, and especially if that is infiltrating at the front, I wonder if you have managed to control that? There are a few great threads at managing the supply air external vs internal on this forum. Seems like there are a few DIY threads, and they are very informative. I think djkeev may have one of the best visually informative ones with lots of pictures that I have poured over many times in contemplating how to handle airflow. I also think there is a good front nearly drop-in solution that couples an evap unit into the front air box right with the heater core. I'm sure I could find those threads again, if you can't. Also, you might not have heard of TenCent's kit. I'm still trying to budget it in, as I see it as a total no-brainer -- it clearly needs to be installed on my rig. You might want to take a look at his recirc ideas in the information on his interpretation of what needs modification in the front end at vanistan.com in "other accessories". Opened my eyes, for sure. Sure like how you move forward, its inspiring! Good luck!

I'll see if I can locate photos but someone made an overhead evaporator system that mounted inside over the driver and passenger cab area. The piping came up the left "B" pillar if I recall.
It Had vents blowing to the rear and vents blowing to the front. Very rarely seen.

The SmallCar in dash unit is more $$$$ than I have to spend. Thanks for the tip on the Vanistan Fresh air kit, nice solution. I am just about to install a front heater core and refresh the front airbox with new flap seals, so I should be good,with controlling fresh air flow.

Wow! That ceiling unit is nice! Looks to be beyond my current abilities, however. Also, I don't know,if it would work in a Westy. Can the front roof support something like that in a Westy?

On my drive to school (aka third grade happy place!! Rolling Eyes ) i was thinking that the Nostalgic air floor unit I am focused on now may just fit on the floor of the front passenger seat. Of course this is just a passing thought and I have not measured anything. But the idea has merit as the vents can be ducted into the airbox and use the stock vents. more thinking to come!!

Here is a good DIY a/c article started by Howesight you might get a lot of ideas and info out of. You'll still be needing lots of the bits he shows, no matter where the evap unit goes.

This sure looks like a pre 86 AC set up.
The Somebody was VW.

I had one of these in my 85 GL.
Worked great, being that it cooled the inhabitants up front where they usually were, not the entire back end of the van first.

the 83.5-85 front over head unit can be installed in a westy, least I've seen it done. it requires some creativity with the roof latch. as the AC unit goes afew inches more towards the rear..
you might also have to work out a new fabric headliner. the westy board won't work.

In my "ON" and "OFF" process of designing/finding and A/C setup for the van; I have found this small unit that provides heat and A/C. It is quite compact, yet provides 17,000 BTU's for A/C. It almost fits under the dash. It would fit very nicely behind the dash in place of the stock air box.

You're getting better! Not a cheap unit and I do wonder about the (as I understand it) always on feature. You haven't any control of the flow and add heat to regulate temperatures?

574 british pounds is what? $730 US? Plus shipping.

Ya, it is a bit spendy, but it is a complete kit. There is a cable operated heater valve to turn heat on and of and in between. I'm not sure what the always on feature means, I will have to ask them about this.

It is cheaper than the Small car unit however.

I was seriously looking into the Vintage Air units last year. Still may after life's latest challenge subsides.

Contemplated the space above the transmission after seeing what a samba poster (think it was Libby) had done to create a storage space in that spot. Ducting out under the bench seat next to my propex vents. Little bit more spendy but you can get complete kits or as much as you need, and customer support during the build.
