The temperature in my husband's office is so warm, the OSHA guy literally walks into his office, takes a temp reading and says, "Okay, you can go home now."
He doesn't have windows, his desk top fan just circulates hot air, and his office is too small for an "inside" a/c unit to be practical - the heat exhaust has to go *somewhere*.
I'm wondering if I could dummy-rig his fan to blow cold air as follows:
Wrap copper tubing in a circular coil on the front of his fan.
Run each end of the copper tubing into a cooler filled with ice and cold water. (Salt, too, if the ice isn't cold enough on it's own)
Attach a water pump (like those used with small outdoor fountains) to the tubing.
Turn on both the fan and the pump, so the pump circulates cold water through the coils, and the fan blows the cool air off of the coils, and onto my husband.
I don't have any illusions about making it snow in his office, I'd just like to take the edge off of the heat as he sits at his desk.
His office is too humid to make a "swamp" cooler.
