| You can cool the air by evaporation, but it wont make you much more
comfortable in the current weather as you will be increasing the
humidity. The main benefit of air conditioning is that it reduces the
humidity - this is much more important than reducing the temperature.

The air coming out of the evaporation air cooler I've seen is so cold
that the people who use it don't have any water in it at the moment, as
it's too cold to blow on them directly!
Anyone seen these things for sale anywhere?

| You could have some muslin dipped in a bowl of water, with the end
hanging down in front of a fan. If you turn the fan on, then it
will blast out cool water vapour, which should have the effect.

| either that or you'll keep cool by having a constant fine
spray of cold water hitting you in the face...

I assure you ice cold air, whether humid or not, is nice and refreshing.
re fan idea, isn't a bowl of water over an electrical fan slightly
dodgy, or was someone trying this out in the DEC park loading
bay yesterday?
If anyone comes across one of the wheelable heater/cooler/fan ones like
Steve's describing I'm on for buying one too... they really are the business.

| 782.6 | Try Viking Direct ... | ROBSON::PATTISON_M | $on error then RTFM | Wed Jul 27 1994 10:37 | 6 |
| Hi,
I just got the latest Viking Direct catalogue (an office supplies
company) and they have a portable AC/de-humidifier in there for �399
(RRP �699). I can get their number for you tomorrow if you want.

| When you evaporate water to cool the air you wont get much below the
dew point. Warm, humid air has quite a high dew point, and if you
continuously add water vapour you will raise that point. (I wish I
could remember how to convert rh and temperature to the dew point!)
You can get ultrasonic humidifiers that give out a stream of cooler,
saturated air - they look as if they are blowing out steam, but it is
cool.
If you could get hold of a supply of dry ice, then blowing a fan over
that would be very effective.

| All this talk about raising the temperature and stuff is a bit
irrelevant as we use it in the office which is HUGE, so there's not
much chance of it having much effect beyond our area.
The system in discussion cost �99 from Texas about a year ago. I've
seen another one (rebadged) at the Basingstoke Computer Auctions which
went for about �40 so they hold their value well.

Yup, it's all your fault!
I can't believe that in this weather, no-one is selling this sort of
equipment.
�The system in discussion cost �99 from Texas about a year ago.
Unfortunately, Texas don't stock any humidifiers or air cooling
devices. Looks like I'll have to carry on being hot.

hmmmm...�99 - �40 = loss of �59..more than 50%...
damn fine value for money

| If you've been to an auction you'll realise that they hold their value
extremely well. I'd have expected to pay about �5 for it. Stuff like
MS-DOS goes for about �2. A desk worth about �80 went for �20 (it
might have been less cos I was the only person that bid for it :-(

| Steve,
why don't you just turn your workstation off. That way it doesn't
generate any heat. You may also want to try turning your colleagues'
workstations off.
