i have the exact same interest with my clc teardrop… kit just received…
I do not know anything about peltier, but after a lot of investigation i am very interested in the battery (or ac) operated zero breeze unit…see zerobreeze.com.
we will have a fairly extensive solar solution for power including recharging the zerobreeze battery, and we will have a second zerobreeze battery backup.
i want to avoid the noise of the typical window unit significantly installed within the teardrop “cabin.” The zerobreeze unit sits outside the cabin with only small ductwork directing air in and out of the teardrop.
I built a pair of screen doors for my camper that seem to work pretty well…unless it’s raining. I open one of the doors and insert the screen door that anchors in place with a couple slide bolts leaving the regular door open. We enter and exit through the other regular door. Still waiting to decide whether to add a mini-split air conditioner. My mini fridge operates on a peltier system and while it doesn’t use a lot of power it also doesn’t cool to a consistent temperature.
The cooling seems to be a function of the ability to dissipate the heat. When the hatch is closed and there is limited ventilation for the fridge..it doesn’t do too well. I am also trying to dissipate heat from the inverter/charger into the same galley space so that doesn’t help the situation. I’ve ordered a small cooling fan that I plan to install in the wall between the galley and cabin that I hope will help the situation. The fridge is a “Cooluli Infinity Black 15 Liter Compact Portable Cooler Warmer Mini Fridge for Bedroom, Office, Dorm, Car – Great for Skincare & Cosmetics (110-240V/12V)” that I bought on Amazon. If the hatch is open the fridge does fine.
