COP to 5 7 to-Air Heat Pump Air inside monobloc

In the interest of Hic himself, I also think it is desirable to lock and forget ... µ

while he goes to borrow a thermodynamics manual from the nearest library;

without wanting to be mean, Hic. See you soon, with better ideas.

He can read:
http://fr.wikipedia.org/wiki/Thermodynamique
http://www-ipst.u-strasbg.fr/cours/thermodynamique/
and also the links included in these basic texts.

Finally I advise to read the basics of logic, essential in physics,
http://fr.wikipedia.org/wiki/Logique
http://fr.wikiversity.7val.com/wiki/Int ... %A9matique

different from that of shadoks:

and a heat pump is not a shadok colander !!

However, I tried to summarize the principles of a CAP above.

He doesn't seem to care much, and want to understand anything. For example, in a pAC, it is not the air that is compressed ... but a fluid that goes around in circles! I did not even mention the mass heat of change of state, to simplify ...

So let him dream of the genius that he is, in his own eyes ...

For my part, chao. If he wants to understand I explain. If he wants to be genius all alone, I pass my way ...

we could make a heat pump by compressing the cold air from the outside to warm it ... but what to do with this compressed and hot air ... if we relax it to release it in the room to be heated it cools instantly!

it is therefore necessary to use the heat of the compressed and hot air by an exchanger, and then to relax it by recovering the mechanical energy by a compressed air motor

it was used as a refrigeration machine, but it is less efficient than the current solution with liquefiable gas

[dedeleco]

Any physical phenomenon makes a CAP!!
With more or less yield , even absorption or adsorption on carbon, zeolite, the dissolution of salts, magnetism, piezoelectric, the passage of a current with Seebeck Peltier effect, simple to implement, especially if new materials with better performance are confirmed or a rubber or a spring, it all depends on the properties of the material !!!

The air is not that bad, but just acetone, butane, etc. will be better with greater spontaneous volume variation !!

Yes, you're right. I simplified outrageously. Already, the principle of the liquefiable gas CAP is not assimilated in this thread, so ...

In this case, above, confusion between the "heat transfer fluid" and the air in the room ...

It does not matter: if condensation / evaporation or "compression / expansion" are carried out in the same room, this amounts to recovering only the losses of the motor and compressor, ie the electrical energy consumed ... And COP = 1.

Less than that, you forget all the losses of the machine and its consumption.

it is weird this thread ...

All these losses only heat at the end and therefore COP = 1, like a vulgar electric heater at 10 €, unless you throw the hot air directly outside !!

This shadok thread is for testing the assimilation of the basics of thermodynamic principles !!!
