Any chance we could get a model number on that Dyson?
I'm melting over here.

I don't want to crap on the lovely Jenny's purchase, but Dyson fans for cooling are really no better than a €20 bog standard pedestal/desk fan. The only measure which colling can be assessed when it doesnt have refrigeration/air-conditioning is airflow. How much air it pushes around, which has a "forced convection" effect. And all the Dyson blade-less fans do this worse than the traditional fan. It is also worth noting that the higher the temperature gets, the lower the effect forced convection will have. I should say that I deeply, deeply dislike Dyson as a company, as I think they pretend to invent things that have been around for years, and then charge you 10 times the price for the privilege.
They do have the benefits of filtering the air, albeit worse than a dedicated air filtration system.

How can it lower the temperature?
I don't get it.
PV / T = a constant
I can't see how a fan can lower pressure or volume.
Need help

Forced convection can speed up the natural heat transfer, as long as there is a temperature difference between the body and the surrounding air. The same was a fan oven cooks faster than a conventional one. Basically, if you are in a room with zero air circulation, the air around you warm to your temperature on a gradient relative to the distance around you. A fan makes sure that the temperature difference between the air around you, and your body, is as high as it can be at all times,by replacing the air you have warmed.
But if you are in a room that is approaching body temperature, a fan will do absolutely nothing.

PV / T = a constant ... has nothing to do with the convection parameters of a fan.
Dafuq are you even talking about?

Oh I've waited so long for a thermodynamics fight to break out here.

That's the kind of reaction that deserves it's own monument.
But that's not the world we live in.

Isn't amazing how some people are just complete dicks even when there is no need.
