Dyson AM02 Mini Tower Fan
for me dyson is like apple, brand prestige and arrogance with some saleable hardware, but daylight robbery when looked at objectively. Dyson's hand driers use insane amounts of energy, I'd guess this uses more than a normal fan. It's for people who have ipads built into their bath, and people who aspire to have ipads built into their bath. I'm all for innovation and design elegance, but for me dyson are hollow.
I don't get why the noise level isn't at the top of their list of improvements. Is it only me....and most people I know, who consider fan noise the most important aspect?
I have a question for you have you put this in a warm room with no windows? I have a small treatment room which gets very hot and seems impossible to cool with fans but just wondering if this baby would be worth investing in?
No. All it can do is warm the room up. Any device, fan or whatever else, will warm the room up in the same measure that it draws power from the socket. It matters not whether the device is billed as a heater or a TV or a PC or a fan - if it draws 500W then it is a 500W heater.If you want to cool the room down then the unwanted heat has to go somewhere, like out the window. And unless it happens to be colder outside than in, you will need a heat pump (aka air con) to push the heat out against the temperature gradient.
You are wrong. There is a big difference between a 500W heater and a 500W fan. The fan converts most of the energy into kinetic energy, not heat. This is elementary school science.
...and then the kinetic energy converts to [fill in the blank] as the air flow loses speed.Actually the question is beyond elementary school level since it involves the concept of entropy (which always increases), not simply the concept of energy conservation.
It is a cold day. Toboev is feeling chilly. No problem, he'll just turn on the fan. Ah. Problem solved.
Why don't you turn on the heater instead? Someone asks. 'Don't be silly', says Toboev. "There is no difference at all between the fan and the heater!" exclaims Toboev, after a sneeze. 'Everything converts to heat!'
He continues to mumble something about entropy. Meanwhile, the other person shakes his head and moves on.
There's simply no helping some people.
I notice you don't engage the question (i.e. fill in the blank), just engage in sarcasm.
Potential energy. Please think about it while trying to heat up a cup of tea by blowing air at it.
Still the sarcasm. I'm not sure what you think that adds to the points you try to make. As to potential energy, how? And what happens when that potential energy is returned - it can't just build up forever.I'm not sure why you don't want to see that all the energy drawn by any electrical appliance, fan or other, eventually dissipates as heat. The only cooling effect of the fan is on you, the warmer body in the room, assuming the ambient temperature of the room is lower than your body temperature to start with. But it can't cool the room itself, only heat it up. The OP was wanting to do the opposite - to cool down a windowless hot room. A fan can't do that, not even a Dyson.I'm happy for you to explain why I'm wrong, but childish sarcasm and posturing isn't helpful.
I only have one point to make, and it is a simple one.
You are wrong: A 500W fan does not produce the same amount of heat as a 500W heater.
Yes, even in a room with no windows.
I agree - to a point. The fan will heat the room. However, the 500w fan is not as efficient at heating as a 500w heater
