Talk:2790: Heat Pump

woah! an xkcd with color what was the last one with color? (im kinda new to xkcd) 172.71.122.48 21:17, 16 June 2023 (UTC)Erfaniom

I guess the last one with a lot of color was 2750. More at Category:Comics with color. 162.158.167.11 17:29, 17 June 2023 (UTC)

I suppose color was needed to show the air temperature. Odd, though, that in summer (in the northern hemisphere), the character is trying to increase the indoor temperature. Davidhbrown (talk) 21:27, 16 June 2023 (UTC)

He's not. He's moving the hot air from inside to the cooler outside. Barmar (talk) 22:18, 16 June 2023 (UTC)

he's actually heating it, the comic is set in winter. It's a reference to the discussion about regulating heating systems in Germany. I added something about that in the explanation, but I don't think I made the citation right (I'm not to editing wikis) User:Marta (talk) 05:25, 17 June 2023 (UTC)

The citation does not appear to strongly relate to the comic to me. I might be curious if Randall had a lot of comics queued and actually published a winter one in the summer, for example. 172.69.59.112 00:19, 18 June 2023 (UTC)

I agree, I think the Germany thing might probably be coincidental. Randall lives in North-Eastern America. It's unlikely, though quite possible, he was inspired enough by such foreign matters to base a comic on it. Still, you never know from whence inspiration may strike, in which case he published when he thought of it instead of when it'd be relevant... NiceGuy1 (talk) 04:40, 18 June 2023 (UTC)

Nearly right. Simple "insert URL" as a 'number' is single []s, or [<url><space>some text] to have it given linking text (preferable).

Plus you seem to have not used the four tildes, i.e. ~~~~ to sign the above comment (made it correct, for you), plus confusingly replied before another reply (so I indented you a bit more, as well as it now having that timestamp to make precedence clear).

But these are all things you'll pick up, I'm sure, if you're going to be getting [used] to wikis... Welcome! 172.71.178.139 05:35, 17 June 2023 (UTC)

I actully think he's warming the inside, already warmer than outside, by effectively (and literally!) squeezing the heat out of the cooler outdoors air.

By compressing the cool outdoor air, he increases its temperature (p1v1/t1=p2v2/t2) to warmer than the warm indoor air, creating a squeezebox->room flow of heat energy, then returns to the outside before decompressing and lowering the temperature in his squeezebox below the cool-air temperature in order to create an outdoors->squeezebox flow of energy and repeat. (The comic has the cycle start at roughly half-way through that, and wraps round, but the heat-to-room seemed the most obvious starting place here.)

Right now, I'd not wish to heat my indoors up (even at 11:30pm, like now), so I agree that it's a funny time of year show heat-adding (rather than heat removing), but it definitely is that. 172.70.86.154 22:31, 16 June 2023 (UTC)

Assumption(?): Indoors is on the LHS and higher, outdoors on the RHS and lower, door opens outwards and steps down to "outside". He COULD instead be cooling a basement apartment with a door that opens inwards (like mine)... however he seems to make a noticeable difference to the red, not the blue, so... probably not.  :-/ 172.70.34.160 02:36, 17 June 2023 (UTC)

Since panel 3 shows it at its widest and bluest with "Release", I understand that to mean he's releasing the heat outside from inside - like an A/C does. The weird thing is then showing the reddest/smallest with "Radiate", that word means "make and release heat" to me. The thing is, past experience tells me Randall lives in roughly the same part of the world as me, same climate. That he's in the northern states (like, within a day's drive of the Canadian border), and the Eastern time zone, and it's summer for us. Only heat pumping people should want is pumping heat OUT of the house... NiceGuy1 (talk) 04:16, 18 June 2023 (UTC)

Wasnt there a "My hobby is to open my refrigerator and when people tell me that doesnt help, I sneak into their house and use their AC?" Comic? I cant find it, but we should link it in the "how leaving a fridge open doesnt help" section 172.71.142.158 23:36, 16 June 2023 (UTC)

Sounds like Steven Wright, he has lots of those "my hobby is" jokes. Barmar (talk) 13:29, 17 June 2023 (UTC)

I think it's talking about leaving the door open in general i.e. forgetting to close it when getting groceries, not specifically when he's moving the heat pump Firestar233 (talk) 23:40, 16 June 2023 (UTC)

I can't think of a good reason to say this, but my new fridge doesn't warm up on the back. It warms on the sides. A bad (and quite a PITA reason) is I had to get a new fridge. Protip: don't panic, and do put the sacks of ice into something that won't leak. First time I've met a fridge that doesn't warm on the back. Btw, red hot blue cold. Pink? Light blue? A light blue a pink? Shrug. 172.70.43.31 23:57, 16 June 2023 (UTC)

How many trips would this take? I'll leave the exact parameters of the calculation up to you. (Nerd sniping attempt.) ~ Megan ^she/_her ^talk/_contribs 00:20, 17 June 2023 (UTC)

42. But stick figures are just lines and have no surface area for heat transfer.
