shanghaibebop , 11 months ago (edited 11 months ago) No, unless you are leveraging evaporative cooling, that amount of circulation isn’t going to get you much. Just get a real geothermal hvac system if you have the opportunity. Incredibly efficient. Back of the napkin conversion: 20btu/sqft recommended cooling capacity. 1btu = 252 calories (small) A 60k btu cooling needs 15120000 gram degrees C of water. Assuming you have perfect heat exchanger on both ends, that’s 15120 liters-degrees circulated per hour. Pumping that much water alone is going to be quite a bit of energy. Then you have the problem of heat exchanger. There are lots of sizing mostly based on the deltaT temperature difference. Realistically, without some agent evaporating and recondensing, you’ll have a massive water to air heat exchanger that’s not practical at all. If you want to do more research yourself, heat exchanger sizing can be found in mechanical engineering and chemical engineering handbooks.
