Many of you have no doubt heard that parts of Europe are having a pretty bad heat wave.
What with one thing and another, it is neither practical nor economical for me to buy an A/C unit right now. For one thing, the available ones suck. We had one where I used to work, so I know the short comings of the typical European A/C unit. For another, they are are too expensive - and right now, I’m not sure I could even find one to buy.
I don’t think I’ll do it, but for the last few days I’ve considered going to the dump and getting an old refridgerator with a freezer compartment and rigging an A/C out of it. The biggest thing stopping me is knowing that it would (at best) look like a piece of junk, and the wife won’t let me keep something like that around.
Aside from certain mechanical problems - which I can figure out how to handle - are there any reasons why it wouldn’t work?
What kind of duty cycle is a fridge compressor rated for? I would expect the rig to have to run hard to cool off this big rock pile - even cooling just one room would mean cooling the warm walls. That’s one thing I see as a problem - the compressor not being up to a long time running.
A thermostat wouldn’t be a requirement - cheap and simple would be the rule, and I could turn it off if it should ever approach being too cool.
I could tear it apart and put the compressor and evaporator outside, and run the lines through a board I could put in the sliding door, so separating the hot from the cold could be done.
Would the cooling coils be a problem? Would they tend to freeze up, and would it help to keep a strong air flow over them? I expect that at the very least I’d need a bucket underneath to catch the condensing water.
Anyone ever done this before, or have any ideas about how to do it?
