And someone else responded: > Using Duck-tape? ;-) Exactly! They work fine, as long as you install them with duck tape. ;-) Seriously, ductless mini-splits are an interesting idea. However, you might have to do some significant tweaking to fit one into your EV. I first encountered mini-split aircons in South Korea in 2000, and was impressed at how quiet and effective they were. I was there again this summer, and 14 years later, they're absolutely everywhere. I happened to look out a window into the central courtyard of a Seoul office / retail complex. I saw what must have been well over a hundred mini-split outdoor units, all stacked up 6-8 units high! Regrettably I didn't have time to stop and snap a pic. I use a mini-split here too. In fact it heats and cools the room I'm typing in right now. I like it well enough, but let me tell you, it's not as small as it looks in the pictures. The early Samsung aircon-only units I saw in Korea were wide, but not especially high or deep. That may still be true of aircon-only units. However, the 9kbtu Mitsubishi heating/cooling unit hanging on the wall to my left right now is HUGE. The size of this system is mostly in the coils, I think. The outdoor coil is about 26" by 18". I'd guess that's for improved efficiency and heat pump effectiveness (it will heat down to something like -5F). You might be able to mount the outdoor coil where the ICE's radiator lived, if you weren't going to fill that area with batteries. I can't imagine the indoor coil fitting into the heater box of any car I've seen, though. One possibility would be to use standard auto coils and repurpose the compressor. It's inverter-driven, so I'd guess that it would probably run on 165-175vdc. The reversing valves might be usable too, depending on what controls them. You'd probably need some EE / IT chops, because there seems to be quite a bit of micro-driven electronics controlling the compressor and valves. Mini-splits aren't cheap, but I'd guess that buying one and chucking the coils would still be cheaper than buying a purpose-built EV aircon system. I expect that adapting it wouldn't be trivial, though.
