iv'e thought about making a hole in the floor for the exhaust pipe and the water pipe to drain out since them water buckets fill up fast in them portable units to me that would be more stealthy...
I am looking into cutting an exhaust hole for the portable A/C I recently acquired. The only question is where? The hole would preferably be in a accessible and non-obstructed place, support multiple orientations of the AC (say I desired to turn the portable so the air blows in the cab, or move it to a different position. I am thinking to minimize hose rigging I would need to have multiple in-floor holes. My only concern with porting the exhaust on a portable AC through a van floor is the heat rising, pooling under the van and cancelling out some of the cooling inside the van. If one is really concerned they could install PVC pipe to pipe the exhaust air to the side of the van.
To be on topic here is my opinion of cooling oneself down who lives the van life:
I am a fan of evaporative cooling when it can keep one in a comfortable temperature, having built two FIGJAM 5-gallon bucket coolers for Burning Man. I am into it because evaporative cooling can take upto an 1/8th of the energy of A/C, and can make a space upto 30 degrees cooler. I don't see the space for two bucket coolers when going fulltime, plus I desire something built-in to the van. Is there a compact, high-surface-area, auto-replenishing, low energy consuming and most importantly low-cost evaporative cooler system for vandwellers? I am thinking the best place to install such a thing is under the van since whatevers underneath is shaded by the van, it would take up little to no interior space
I was in the Hitchin Post RV park in Las Vegas for the EDC trip, hooked up with 11000 BTUs of A/C. Being parked in direct sunlight (RV parks should offer some kind of shade structure over the RV spaces as an amenity, removeable for the winter season), it was only enough to bring the van down to a comfortable level. The other half of the days in Vegas I had no means to power the A/Cs since I didn't have the 3200 watt genset I do now. I saw people powering a 5000 BTU window AC with the 800 watt HFT genset, which I tried multiple times with little sucess. I tried it in vegas and it didn't work, perhaps due to the altitude.
I now have a combined 17,500 BTU of A/C in the van, after two summer trips without some form of A/C that can run anytime in the van (Burning Man 2014 & EDC Las Vegas 2015). Never again will I be willingly swealtering! The portable is great because it streams the air towards the back on the ceiling, creating this cascading cool that distributes the air conditioning evenly. Of course the generator will need to run to power the A/Cs, which I am ok with. Most places I travelled on trips I do not have the luxury of parking in a shaded spot.
The way I see it, a slow fan is better than no fan, 1/2 working A/C is better than no A/C, and getting the interior down to a comfortable level (80 F inside with 105 F outside, van in direct sunlight) is better than a 10 degree temperature drop. So if you're poor like me and want some luxuries it pays to have this kind of mindset. Any improvement is better than no improvement. Instead of spending years like a desert hermit to get up to a certain level, or repairing/replacing low quality stuff, one can pull more income and accelerate their rig setup. I ask you to think long and hard about this: what is more valuable? Your time, or your money?
