Can the radiant tubing in a geo thermal system be used to cool a floor just like it’s used for Heating a floor or is duct work a must ? What is the best way to cool with geothermal system ? And this is up north where it will only be needed 2 months of the year .

It could be used for that. Battleship magazines used chilled water radiators to cool them. As to the best way, I’m not sure. I could see where you could get a lot of condensation if random cold surfaces are placed around a house.
ya I’m seeing that now after the previous post, but how do you take advantage of the geothermal to cool air ?
2 ideas come to mind:
Run a dehumidifier. If the moisture isn’t in the air, it can’t condense on the floor.
Run it through a separate zone with a water to air heat exchanger? A fan blowing through it would probably keep the air warm enough at the exchanger to keep condensation down and cool the air enough that you’ll enjoy it. Like the radiator in a car, but cool water going through it.

Dr. Carrier invented air conditioning primarily as a system for controlling humidity. As it turns out AC works great for controlling temperature in the conditioned space as well, but dehumidification is essential for comfort. Cooling the floors would tend to cause dankness. So if you have a plentiful source of cool water it should be used for a water-to-air heat pump system that can cool the air below the dew point before returning to the conditioned space. I have seen systems where concrete walls and ceilings were cooled hyronically to reduce sensible heat load, but dehumidification was needed as well. (And I suspect cold feet even in summer would be uncomfortable regardless of the humidity level.)
