RE: HAS ANYONE BUILT A GOOD HOSE COOLER?
I still think your best bet is installing a small room air conditioner and ducting the output air to the cpap intake. Run the fan on low speed to get the coldest output air. But I only worked in the commercial refrigeration design, construction and servicing field for 35 years before retiring, so what do I know about heat exchange technology and application, except possibly what's in an ASHRAE manual. If you folks manage to pull off a breakthrough that makes the info in that manual obsolete, you can expect great things will be coming to you, like fame and fortune. I've always found that when you start jacking around with air and trying to change its properties, you fall prey to psychrometric chart values that can lead some folks to be aghast at how much latent heat must be removed from some air samples before the specific heat/temperature can be lowered.

Psychrometric chart. Latent heat. Sensible heat. Dew point..... Hmmmm now where did I see that? Wink

.
Did you do much ammonia? I generally tried not to let the hall know that was one of my skills unless things were Really Slow.

LOL!

I use my PAP machine nightly and I feel great!

250 is in CA but I came back to IL to the old elephant burial grounds to retire. Actually did a little ammonia work on an ice plant... I could see where it could be impressive...well, let's say it could leave you breathless! You're smart to avoid it.

Best regards brother.

Anyone using 20mm copper pipe? That would get you maximum heat transfer. (10ft in a coil)
However...That might detune your APAP - CA/OA echo sensing though.

RE: HAS ANYONE BUILT A GOOD HOSE COOLER?
I usually place a few ice cubes in a shallow bowl which is placed near my S8's intake. Cool air is pulled in and passed on to my appreciative sinuses. Never had rain out or any other issues. I have not tried the ice cubes in the humidifier chamber, but may tonight.

RE: HAS ANYONE BUILT A GOOD HOSE COOLER?
I would be reluctant to have the ice right in front of the intakes.
The sensors inside the CPAP machines do not play well with moisture and
having the machine inhale cold air may promote internal condensation. Not
a good thing.
I would go for a final chiller stage *after* the CPAP is done with the air and its on the way
to the mask.

Putting ice in the humidifier reservoir will cause it to sweat on the outside and you'll get water accumulating in the machine where it may cause harm.
