Cooling down without Air Conditioners

[Guest]

If our society actually cared about the envirement we would be using ammonia system for much of our cooling.

They are more efficient, and ammonia is envirmentally friendy. It doesnt smell nice if you have a leak, but its not really dangerous.

If large chemical companies werent making Freon etc we probably would be now using ammonia for a large percentage our cooling rather than in a few isolated warehouses.
