It technically would work, and in countries like Norway where you will always get cold water out of your water supply for no cost it’s economically feasible.
The thing that makes it not worth the effort is similar to how you can blow away a pea at an armlength away, but you can’t suck up a pea from the same distance.
Radiators when heating, expel heat not just through convection but through radiation.
When cold, they can’t un-radiate, so you are left with convection. This is very slow, and won’t work for the room the radiator is sized for.
To make it work, you have to heighten the convection by blowing air through it, and now you basically have a regular Air Conditioner which already exists. :)

Ah, thanks! Even though I had some severe (now corrected) misspellings in there?
