My wife and I perform music for our living, and we tend to get very hot while performing. She often gets so overheated that she has to sit down. I want to know if they make "air conditioning fans" that are essentially pedestal fans with a small air conditioner built in, so that they project cold air out from the fan blades. I know that such a device would be essentially a zero-sum game as there'd have to be a heat outlet at the back, such that the overall temperature of the room wouldn't change, but I want to find something that projects cold air at a person without the use of "misting" (which would damage our equipment).

Any thoughts?

About the only way is to make one yourself.
Basically, you can take a good size pedestal fan.
Then put a copper spiral shaped coil in front of the fan.
Thru this coil you flow cold water.

The cold water comes from a bucket/container with ice water in it.
A small pump circulates the water thru the coil.

You WILL get cold air this way.

You cannot make an air conditioner that way. While it will provide cool air, you will not effectively condition the air to be dryer (less humid).

True, though all I'm looking for is something that will blow cold air. Humidity, and the removal thereof, are non-issues.

Approach it a different way. Perhaps an 18" diameter x 4" high metal platform that can have a block of ice in it for her to stand on. Although bulky, "cool vests" can work. Neck coolers can be effective.

I take this is outdoors which is not the design of air conditioning cooling at all. You might look to dry ice with air flow over it but likely that means adapting normal outdoor fan.

Nope - indoors. Hence why there is usually no air flow.

They did exist in the 90's. I had an indoor one where I filled it with water and the system cooled the water to where it was near ice cold and then the fan blew out the cold air. It was pretty good for a few years but the coils inside corroded and that was the end of it. Haven't seen one since. All the current ones now require an exhaust hose and create it's own water from the moisture in the air. Tried one (8000 btu) of those and it was junk.

fwiw
Before someone says it was a cold air humidifier, it was not. The fan had multiple speeds.

Have you looked at evaporative coolers? While not a pedestal fan, I think they could work. They don't "mist" and they come in different bodies. We used a portable, larger one in AZ and a smaller one in our house when it was dry out. The small one came with blue ice to put in the water and it did a decent job of blowing cool air. Maybe something like this: Luma Comfort 250 CFM 3-Speed Tower Portable Evaporative Cooler-EC45S - The Home Depot a lot of places sell them IF you live in the SW US.

The only pedestal fans that I have seen were mist-type. The evaporative coolers, portable, are pretty light weight so could easily be transported. Portable air conditioners are heavy.

Remember it depends on now the surrounding air is in moisture levels. Otherwise you could end with what you see on football fields with what effect it has on your instruments and even looks. You can spray a mister system in summer heat of Vegas from ten feet and not a drop hits the ground.
