Dr Gorrie's air conditioning was to hand a block of ice in a suspended bowl above the patient and let convection currents coming off the ice fall and cool the patient. The system was not practical. The big invention was the steam powered ice maker that made the ice.
A while later fellow named Carrier modified it and made the systems we are familiar now.

Gorrie did originally start off hanging blocks of ice in hospitals, yes. But later, he invented the first mechanical refrigeration system ever created, and was granted Patent No. 8080 for it in 1851. I'm assuming this is what Ock is referring to.
Willis Carrier wasn't even born until 1876, a full 25 years after Gorrie had already invented mechanical refrigeration. So any suggestion that Carrier is the true inventor is pure myth, as you can quickly discover yourself, when you realize that Gorrie's 1851 Patent No. 8080 for mechanical refrigeration was granted a full 25 years before Carrier was even born, let alone manufacturing air conditioners. That would be some feat! I can't picture a bunch of sperm manufacturing an AC unit.
So it wasn't just ice suspended from a ceiling, he actually did create the first machine that used the evaporation and condensation properties, of brine solution as ock mentioned, together with mechanical pumps, to create refrigeration. Others had thought up the theory before, but Carrier was the first to actually do it. And Carrier simply carried forward with Gorrie's creation. Gorrie was a doctor, and was concerned solely with cooling hospitals and making ice for patients. I doubt it ever occurred to him to use his invention to cool private homes. Carrier, on the other hand, saw that potential.
So I guess you could say Carrier was definitely the better business man.
