IMO the only place for smoke/haze/fog machines in MJ is very occasionally as part of a theatrical performance. The same goes for strobe lights, or other lights flashing at eye level. Finally we've got rid of smokers indoors, why would we want to be using even "nice" chemicals.
Keep the air as fresh as possible, I may be doing some heavy breathing...

I checked some websites on Haze machines and the principles behind it. A Fog machine creates the fog using water vapour on a heater, where a haze machine creates the haze by injecting the liquid with high pressure through a nozzle (no heat) The liquid used is an oil based liquid rather than water based and so that is why it lasts longer - but completely non toxic and poses no health problems.
I couldn't find anywhere that says that it will cool the air, so I'm not sure if that's just a knock on effect from the tiny particles in the air hitting the skin and making it appear cooler. I guess though that as it's created without a heater it will also seem cooler, but that's just my assumption.
Pressurising the liquid will create heat.. which will generate the haze...just without the use of a heater.
Pressurising it will increase its temperature, but the depressurisation will reduce its temperature again.
Blowing up tyres heats the air, tyres and pump. Spraying an aerosol can will cool both the can and the spray. The CO2 that comes out of a fire extinguisher is pretty cold too.

What about these ultrasonic water foggers? Great for humidifying the air (I have one at home) but I imagine low lying water vapour on a dance floor would be a BAD idea!
Is this what the Casbah is using?
Um... Is there a scientist in the house?
I'd imagine as the water starts and finishes at normal air pressure it will not be especially hot or cold, though perhaps turning it into a mist will have dropped the effective pressure, so it will be colder.
I don't imagine the nozzle will get noticeably hotter as the water going through it will cool it.
It's the compression and decompression of the coolant in fridges and freezers that makes them work, but I've never been entirely au-fait with how these things do their thang.
