Think of it as a super-sized bathroom fan, except that it is installed at the top of our stairs in the ceiling. Internally you just see some light plastic grating and can kinda see the louvres inside if you look hard enough, and beyond that I can't recall if there are 2 large fans or 4 smaller ones. Dimension is approx 20"x 30". The fan "sucks" in the air from inside the house and discharges into the attic space. Requirements include: having adequate flow of external air into the house, and more than adequate attic ventilation (which might not exist in older homes).
Adequate flow... so you open a door, or window, or combination thereof. You must *not* operated without opening an external source. For obvious reasons it needs to be cooler outside than inside... so the cool air is "sucked" into the house thereby displacing the hot air which is exhausted into your attic. At some point the attic space vents through the eaves and also then gets cooled. If we want the whole house cooled we'll open the door or window furthest away from the fan. At bedtime we open our window and the junior(s) open theirs... we use either the 2 or 4 hour timer, and high or low speed, and it just shuts off automatically and closes the louvres. Yes it is possible to actually get too cold. Also works well if you over-cook something on the stove and make the house stink.
Only problem that has occurred was we had our home humidity too high for a few years and in the harshest times of winter we had condensation form on the fan frame. Also some of the attic insulation got pushed away too far from the device so we got some slight browning on the ceiling within a couple inches perimeter.

Is it something like this? I didn't know this was a thing, but it definitely makes sense since I turn on the bathroom fan at times to try and move hot air out. I was thinking of just nabbing a 10K BTU or higher portable AC unit, but this might work just as well/decently in tandem with that idea. Neat!
I wonder if I should give my electrician a call and jerry rig something like this in my own home (it swelters something fierce). Heck, it seems simple enough that I could just do it myself and use an extension cord to the nearest plug.
I was thinking I could do it for the summer only. I'd have it mounted into the panel that allows me into the attic. In the winter I could swap back to the regular wood panel cover.

I figure it'd be neat for the guy on the other end to open the box and get to share some goodies with his friends. Anyway, I just received my product back and all my treats were in the box still. I guess the guy didn't feel right about taking the candy, or maybe thought I poisoned them or something? Idk. Either way, it's like December me bought May me a bunch of awesome candy and I've been gorging on it all week.

Did you leave a note saying they could have the treats/explaining it's a cultural exchange of gifts and they are free to just keep the gifts, or they can feel free to exchange the gifts with something of what they perceive is equal value (and even suggest licorice type snacks)?
One of the cultural differences I've started noticing on occasion in China is that there's a huge concern about corruption. This started quite a bit more seriously about 5 years or more ago. I think it coincided with some internal news reports of certain politicians being arrested (and possibly executed?) due to corruption scandals. Some places will not accept even an extra $1 HKD or 1 Yuan as a "tip".
