Radiator calculations

With the addition of the fixed fourth radiator panel, the heat rejection capability is 29,000 Btu per hour= 201 lbs of ice per hour.

1000 tons = 200,000 lbs= 995 hours of shuttle cooling.


"1 ton" of air conditioning from the amount of heat that 2000 lbs of solid water will absorb over a 24 hour period (that is to change from a solid to a liquid). It will absorb 288,000 Btu's in a 24 hour period, 12,000 Btu's in an hour. That is why we call a 12,000 Btu/hr unit a one ton unit. In an average size home (1500 sq ft), the /normal requirement would be about 36,000 Btu/hr.

288000 btu/2000 lbs = 144 btu /lb
