Most cost-effective cooling method?


Hello,

I'd like to know what are some of the most cost-effective cooling methods, either for rooms, reaction containers or generally speaking.



Thank you :)

Live in the arctic.

Next time be less vague when starting a new topic; put a little thought into it, and show that you've done some research on your own. Reporting my reply as "useless" and a "troll" post is uncalled for, considering your initial post. Don't blame others for your lack of understanding and clarity.

A vacuous question earns an insincere response. :P

math, do you have a specific problem you're trying to solve? It is essentially impossible to answer your question as posed.

The Antarctic ... lol :P

Your question is very vague though, cooling for a reaction vessel... Cooling for a room... (There's a difference in size, amongst other factors). For a reaction vessel... An ice bath I guess? For a room... An air conditioner I suppose? Elaborate a little bit on your inquiry, what are you trying to cool?!

Sorry about the question but I need a dust up of cooling methods.

I'd like to know what are some electric cryo-generators called like and if relatively inexpensive ones exist, and if say cooling iron pieces in liquid N2 would be more cost-effective in cooling a room air temperature (by conductivity and reachment of equilibrium temperature between the iron mass and air), you know the classical m1*c1*T1 formula where m is mass, c is the heat capacity proper of the material and T is its temperature.


Thank you

Google ' Magnetocaloric effect ' , the rare earth metal Gadolinium exhibits this most.

Very vague question,, barring liquid nitrogen maybe acetone + dry ice bath? Please elaborate.



A question that sometimes drives me hazy: am I or are the others crazy?

if you want to cool yourself down, put a thin layer of water on your hands and wave them around, it will feel as if you have acetone on the hands, which ofcourse will be even colder if you use that instead of water

for cooling down reactions you can put a beaker reacting in some cup of a sort and put running water over it, more surface the better ofcourse
salt can be added to cool furthermore
ice salt and water is also really great

for rooms you just want to remove the air or do some reactions alike titanium chloride (or was it titanium perchlorate, that decomposes endothermically?)




~25 drops = 1mL @dH2O viscocity - STP
Truth is ever growing - but without context theres barely any such.
