Now that my heating season is over, I want to work on a cooling & dehumidification project. We use a lot of well water on our farm (about 500 gallons/day, maybe up to 1000 gallons/day). All that water is going though a 1" line in my basement before going to where it is used (mostly outside). I would like to run that 55F water through a water to air heat exchanger to cool and dehumidify. Pressure drop through the HX is not a problem, I can pump 30GPM at 70PSI with my Grundfos constant pressure pumps. We typically do not run more than 10GPM. I was thinking of a simple HX with a fan to blow air through and a drip pan for the condensation. Air temp going in would be about 70 to 75. Any ideas on an appropriate size for the HX? If it is too small/too big would I get the temp drop to dehumidify? Anyone know where to get a reasonably priced HX?
