In very old Earth science, the tropical or equatorial area of the Earth was named the “torrid zone”. Evidently Aristotle was responsible for this, if WikipediA is to be believed. Supposedly the heat would be so severe it would be impossible for humans to live there.
Consequently, the Lennox company used the name “The Torrid Zone” for its brand of… air conditioner.
I am not making this up, as the following basso-relivo advertizment scan shows:
The air conditioner is the box about the size of a large modern refrigerator. Amazingly, the art even includes the text that would be printed on the unit itself, and can be seen looking closely at the original. It reads:
FILL ONLY TO THIS LEVEL
This suggests it either humidified the air, or used evaporative cooling to condition the air. I don’t have a manual or anything to look up how this worked. I also do not have any idea where this came from, but its peculiar design and strength (it’s made of stiff cardboard) suggests someplace where it would have to “stand up”.
Anyway, after that we read
Y24 – 50 – 274
The last line there is a guess. I do not have a clue what the numbers signify. Make, model and serial maybe?
