Hi, sparkchaser,

There have been some folks on this blog who have put such an idea forward, but I don't know of anybody who has attempted it. As you probably know, there are
The single-speed compressor would be the easiest to do, and would pretty much consist of replacing the evaporator coil with an equal capacity liquid-to-refrigerant heat exchanger, and in place of the fan, you would need a properly-sized circulation pump... not so hard to do. As you might have seen, I tend to be pretty fond of brazed plate heat exchangers, but if you have a line on cheap copper tubing, you might be able to make a tube-in-tube that would do it. I have not yet located information that would help me size a tube-in-tube refrigerant-to-water exchanger. You can find new and used heat exchangers on ebay at reasonable prices. Most give specs for water-to-water, which is not the same as refrigerant-to-water. A super cool hack would be to convert an inverter technology mini-split to ground source. There are significant technical hurdles with regard to the inverter technology & ECM fans (ECM pumps?), but the efficiency would be stellar. Is this the kind of info you are looking for? -AC_Hacker P.S.: How far up river are you?
