COP from 5 to 7 for indoor monobloc air-source heat pump
(for a machine with a "standard COP" of 3 to 7 °)
what divides the electric supply by 5 or 7 and that of the rate of KWh
(compared to electric heating - with 20 ° air compression)
Would there be an error ????
In an empty apartment
- 1985 insulation, without heat exchanger,
the temperature never drops below 9 °
(Would not the apartment serve as a Canadian well?)
So ???
why compress air outside at -5 °,
(with a COP significantly lower than 3)
while the air inside an apartment is always 20 °,
(even if the outside temperature is -5 °)
with a COP FROM 5 to 7. . . invariably
COP to 5 7 to-Air Heat Pump Air inside monobloc
COP to 5 7 to-Air Heat Pump Air inside monobloc

I did not understand much either!
You're not going to turn the air of the apartment on itself?
Do not forget that the amount of air at 9 ° from the apartment is insufficient to provide the necessary calories.

Ah I see better the idea ... put the battery outside inside?
In a greenhouse attached to the house the gain can be interesting in mid season (but when it freezes and without sun I have doubts) ...
And to place it in a crawl space (buried and not ventilated in winter) is for when?

hi Christophe
I quote you:
"Ah, I see the idea better ... put the external battery inside?"
*** the indoor compressor compresses the hot air
and reject the cold air outside ***
1. the COP is variable according to the temperature,
2. the commercial COP is calculated for a temperature of 7 °
so if a compressor runs at 20 °,
its COP will be significantly higher than the commercial COP
Heat pumps Air-Air monobloc interior
have a COP between 2,3 and 2,8 at 7 °,
but we get into it since they work permanently at 20 °
and so with a real COP from 5 to 7. . . and permanently! ! ! ! .
that's it ? you have hit!
So the problem is elsewhere,
because that would be

Not at all! What matters is the delta as much as the outer T ° ...
If you have a room at 20 ° C you do not need a cap, you just have to open the door for the heat to arrive

Where do you get this value from 5 to 7? From a constructor curve or from ... your hat?

hi Christophe
there is no "outside T °" nor "outside delta" !!!!!!
since we compress air inside
(cold air being rejected outside)
a compressor raises the temperature more easily
1. compressing the indoor air from 20 ° to 25 °
(actual cop greater than cop 3)
, with 7 ° in outdoor air mdr.
2.
than compressing air outside 7 ° to get 25 ° (~ cop 3 commercial)
to stabilize the room at 20 °

Huh? Must stop the little pills !!
There is always a delta in any refrigerator machine = absolute value of cold source - hot source according to which direction it "turns" ...
I understand nothing about your idea: the hot spring is inside or outside ???
Look at the link on PACs that I just gave ...
