I don't know a lot about mechanical refrigeration, but some of the earliest types relied on running water to chill the air. A friend of mine in high-school worked at a plant nursery that used this method of cooling when the greenhouses got too hot. They would run water down the lower half of the greenhouse window to a splash pad that ran around the foundation. With windows slightly open right at the bottom of the wall, the cool air would flow into the greenhouse as the hot air exited at the peak of the roof. I would imagine that this is the type of cooling that a large building would have used in the 1940s. Maybe it is not right, but maybe this will prompt some more responses. Andrew
