Won't work. Heat radiates, cold is the absence of heat. Think of a match which you can't too close to, and an ice cube. With A/C you're taking heat away from the space and dumping it somewhere else. I suppose you could put fans behind the radiators, and try and dump the heat somewhere else. You got a big heat sink called the earth. You could run some piping underground a few feet to act as a condensor.
