These days after a week or so of camping the cost of the gas burned while leaving a vehicle idling over night in order to keep the cooler running would make a nice little down payment on an actual rv fridge
Not to mention the fine for doing it..
Actually that was back in the day of August 2012. Middle of the heat wave, right through the hottest deserts we have. Gas was nowhere near cheap :/
However, I built an arduino powered MPG monitor that I have hooked to the VSS and fuel injector lines. With this I can monitor how many GPH my injectors are using, and see a real time calculation of whatever I want to program in on the LCD. My little 1.6l Suzuki idles at about 0.18 GPH. For the comfort of AC and electricity for fresh food that works out to be quite inexpensive even at todays prices. The engine is bulletproof and never overheats or anything, and I built the AC system for the vehicle myself for that trip specifically. It didn't have AC from the factory. I don't run your typical refrigerant... So it takes a lot less energy than say R134a or even R12. Can't say much else about that publicly however.
I have idled my vehicle everywhere from NY to CA and averywhere in-between. While I dislike being anything but green, my engine is so small that it is less harmful than most gensets that lack catalytic converters and EGR systems. I also customized my EGR and added a second charcoal canister to handle the extended idle. So far it hasn't killed my catcon, but I use a small one so it is easier to keep heated. Never been bothered by anyone about fees. I thought that only applied to the big rigs?
At any rate I apologize for any form of thread derailing. I will collect some photos and other info about the chiller setup. I have a lot of water cooling components such as waterblocks pumps and radiators. The radiator is 120mm square.
I may build some and sell them to whomever would like one. I also plan on making a batch of my furnace
fan quieting controllers and offering them to you guys here. They are programmed to slowly ramp the fan up to a lower total speed (selectable with a dial) to avoid power waste and loud jarring when you try and sleep. I haven't gotten around to making any more than my first one! They use PWM at 16khz or so for efficiency. No whine either.
Once I have some more time I will get you guys the info on the peltier cooling system for the custom iceboxes. I only built one of them as a fun thing to do. At this point I think it may be a good idea to build a nice kit with a thermostat and all. All you would need is 12v and two holes for the insulated lines to go into the cooler. Easy peasy.
