I have a theory.. this was originally going to be a rig as a gift to my wife's parents, but I want to talk about it first to bounce my idea off of others. We all know heat rises and condensation tends to pool, correct? I present to you, a way to get a working fridge for a fraction of the cost involved normally. Your average drop down freezer is actually rather energy efficient... moreso than a fridge would be at the same temperatures. As I understand it, you want your average fridge to be around 36 degrees. I've owned decently sizable freezers before, and had noted they reach that temperature within a few minute of having been turned on, regardless of ambient temperature. It also holds it's frozen temperature fairly easily, if you're an idiot and leave the top open. A vertical freezer, not so much. So.. this tells me if you're living off the grid.. you should never be using a vertical fridge.. period. Secondly, it gave me this idea. A simple thermostat relay inside the drop down freezer with the power cutoff at 36 degrees or below should actually turn the freezer into an INCREDIBLY efficient fridge. My only issue is that, for the life of me, I cannot devise a schematic to prepare such a thermo with a cutoff relay. There are some market solutions you'd think, but those are all made to turn a unit ON when a certain low temp is reached. As I understand it, this should draw like.. a few watts a DAY provided you don't leave it open for long. Drop down is inconvenient for a fridge but let's not kid ourselves... if you're willing to live off the grid you're already willing to give up things like "staring at the fridge and picking food out of it". Anyone got any ideas here? The makeup of a thermostatic relay like this is beyond my skills... but then I'm probably doing it wrong anyway.. I'm fiddling with resistors and a copper strip and really it's a stupid way to attack the problem.
