:::::The difference between ice-cooling and heat-pump cooling is that ice (outwith the freezer that created it) is a one-shot thing. It can equalise then does nothing more (you've just got a watery whisky, and personally I prefer it neat/as-poured anyway). The heat-pump uses a solid-state (peltier?) or closed-loop (refrigerant) mechanism to make one end of it cooler than the cool environment (heat energy goes towards that) and the warm end warmer than the warm environment (heat energy moves on out of that) without breaking the law that sould otherwise never allow the cool end to ''spontsneously'' give more jeat to the hot end than the hot would like to give to the cool end. Compression of a gas warms it (same heat, less volume, higher temperature), expansion of a gas cools it (same heat, more volume, lower temperature). Add the forcing of phase-change to the mix, in just the right way, and heat energy is made even more mobile (drawn in, radiated out, and transferable betwixt the two sides by advection/otherwise).

::::::Looks like you used a lot of words to say in detail the same thing I did, LOL! The thing is, my ice cube comparison isn't perfect, it was simply to illustrate what I was speaking of: the equalization of temperature by application of a source of cold. You mentioning watery drinks is rather off-topic, that's not actually a part of the temperature transfer, it's merely a side-effect of it, it's what happens when ice warms up. My point is that I was describing a "powered ice cube", i.e. one which remains immune to the temperature change, it doesn't get warmer, DOESN'T result in water, etc. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 03:53, 9 July 2023 (UTC) | ::::::Looks like you used a lot of words to say in detail the same thing I did, LOL!

Technically, it's not the ''ideal'' gas law in play, since air isn't an ideal gas, and the system would behave similarly for closer-to-reality gas behaviour models. But I can't think of a good way of modifying the article to reflect that.

::Heh, that reminds me of my confusion as a kid when sometimes bathrooms would be labelled D and H (Damer/Herrer = ladies/gentlemen), and sometimes P and D (Piger/Drenge = girls/boys).

::What you say is odd... As a Canadian AND someone uninterested in politics, I never know what Republicans and Democrats believe, and I never know what the hell "left" and "right" means - save for being opposite beliefs - or who is what. But I DO know Republicans and Democrats, one is "left" and one is "right", I just don't know which is which. :) [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 05:26, 1 July 2023 (UTC) | ::What you say is odd...

Your parlance vary but to me a heat pump is a device that can heat or cool. (strangely, this would be easier to explain if I spoke of 'caloric' and coolth.' A heatpump is not an air conditioner except that it actually is when it wants to be: it can both move energy into a space and out of the space. Refrigerators only move energy out. Air conditioners only move energy out, (for the standard way to install them) the argue about summer and winter? Stop being silly. Here the outdoor temp has varied a lil in the past ten days. I think from a low of 45F (light jacket weather) to a high of 92 (uncomfortably warm). Here, to keep it comfortable inside at this time and (similar weather in the fall) I need to cool from about 3-7 pm and heat from about 3-9 am. If you live in a country that has rationing, my sympathies. "But apartment manager!! the toilet is frozen over!" "Yeah, doesn't matter. I can't turn the heat on until December 15." Sort of thing.[[Special:Contributions/172.70.130.86|172.70.130.86]] 00:17, 23 June 2023 (UTC) | Your parlance vary but to me a heat pump is a device that can heat or cool.

:¿Que? You sound confused. And pumps (heat- or otherwise) needn't be bidirectional. Perhaps it's easier, even, with something slightly different like a peltier-effect system (with switchable power-flow) than to make a fully reversible source/sink set of radiators and compression/expansion chambers, on top of whatever you do to thaw frosting over of the cool-side, etc. [[Special:Contributions/172.70.86.25|172.70.86.25]] 01:04, 23 June 2023 (UTC) | :¿Que?
