12v Air conditioning vs mini Split

[11overlandram]

Have any of you guys used a unit like this?


NEKOPKKA Universal 12V RVs AC

My Fg has no AC sadly but I only have a 12’ by 6’ camper box so was thinking I could kill two birds with one stone.

Duct a couple of ducts into the cab and leave the rest in the camper.

The other option would be to run a small mini split off the inverter but I fear that the 20% inversion loss would make it less feasible?
What do you guys think?

also looking to upgrade my alternator cause it’s the old 80amp any ideas?

The power consumption with that unit is quite high. It would be really nice if you could get an inverter version of an AC of this size, but they don't seem to exist. Sigh........

You need to get a better inverter...
A good one should have an efficiency over 90%.

I have a Victron inverter it’s 92% or 94% I just thought in general there is a 20% loss

It is likely that a small Mitsubishi Heavy Industries split will use less power than a 12V unit at full power. They are also powered by inverter motors so efficiency at low power settings will be much better than 12V units.
They will also be cheaper.
They are the unit of choice in Oz to run from batteries and solar.

I was thinking of something for a boat without that pileup on top of the box

Most of the marine units utilize sea water as part of the cooling cycle, which is not really appropriate for land based setups.

Blismobill that according to what I understand is the best they use this system, the truth is that I have investigated without finding the exact model.

I have a "Cruise n' comfort" 12v in my npr build. It's great but pricey. I'm using 5-600 watts on full, but does a pretty solid job of keeping me cool. My only wish was it was a heat pump so I had heat from it too, as a back up.

I bought a 12v unit from Sharkaire for my build; it's also a heat pump! I haven't installed it so can't speak to its efficiency but wanted to throw it out there. The company was easy to deal with, and they also make a 24v version:

Hi SkiFeak,
I've been researching the topic of hot environments for a long time and I don't know what the hell of a system the Germans from BIismobil use, apparently there are no fans in sight

there are boat units that replace water with refrigerant, maybe this is the option?

Bliss uses a under bench style unit.

This model but the euro model

At nearly 1000 watts, that's still a pretty big power draw for any battery system.

I was tempted by the Cruise N Comfort VES. But I ended putting in a 3rd reversible vent/fan in the ceiling, 2 very quiet small fans each on front/rear walls, and KCT truly bug proof screens with mosquito and noseeum mesh screens for my 5 openable windows.

 

[Ferjablito]

The calculations are supposed to be more than enough for the German engineers, taking into account that they have a minimum of 400Ah/600Ah victron batteries and high-performance panels.... let's say that the electrical item will be around 10,000 euros.

Isn't your rig 24v?
