Unless your ac is a large one a radiator probably will have more area unless you get one from a compact. Kirk Iran is rioting because of an egregious example...
Vehicle radiators are also more durable and allow for a better flow rate. If you have a limited amount of electricity you might try using a method that dates...
I used a 3 tonn a-coil evaporator and removed the capilary tubings and soldered 3/8 copper tubing to where they were and ran spring water about 65dec throught...
My original plan was to get the "cold" coil from a self-contained rooftop A/C unit in a junkyard. That's the coil that would be in house if it were a split...
Joe most hvac companys replace these coils when the drip pan rusts out and the coil is good for what you need.contact a hvac service and they will sell you a...
An A/C unit is working with much colder liquid. If a 3.5 ton AC unit would cool your house, you would need at least a coil form a 7 ton to do what you want. ...
Hi, Joe, To me, the most crucial difference between an air conditioning coil and an auto radiator is this: in the air conditioner there's a phase change going...

Chris, Just came across this Masters thesis, about solar CSP for a 5KW solar electric generator. See: http://www.redrok.com/NewtonSolarSteamManuscript.pdf ...
