More than that. Maybe another 50 to chill it first.

That's to cool it from 82 to 32 degrees F. Most peoples' cold water is
colder than that.

Plus wattage for a fan to blow air on it. And the defroster to take care
of evaporation from blowing that air on it. Plus a reevaporator fan.

You propose any numbers for these?

And maybe the air conditioning. I would estimate more like 300
effectively.
