I need to buy a portable a/c and wondered where the best place might be to go at the moment. Costco had what looked to be quite a good one unfortunately it was too big for my needs, can't be over 30in high. I know I could google but I am looking for a recommendation.
Yes, evaporative coolers do work, but nothing like as well as ac. They are very cheap to make, very cheap to run, can knock 4-6C off a room, but next to nothing in damp weather, need a bit of ventilation to avoid causing damp, and can be made yourself from a fan + a wet towel. No point paying for one.
We have some large ones at work - they wheel them from set to set. Somewhat larger than a free standing gas cooker.
They work ok, but of course the vent pipe needs to go to the outside. Which is always too far away. So they cool the bit of set in use and roast everyone else. ;-)
They do seem reliable though. Other parts of the building with 'proper' AC as individual two part devices seem to have them not working as often as working.
Yes. I was refering to the type with a single hose you dangle out of the window. That chucks out loads of hot air, but that air was stolen from inside the house and has to be replaced with air from outside. This very rapid air changing inside the house severely limits the ability of the unit to actually cool it down.
I have a unit which is like this. However, it has separate air intake grills for the air dumped outside, and the air recirculated in the room. By sealing the former using cardboard and duct tape to a second thick hose and dangling this outside, the unit suddenly starts working extremely well, as it's not doing a rapid air change in the house anymore.
