COP usually is heat extracted / power input
Note that the units of Heat and Power must be the same. The normal unit is kilowatt (kW).
I have no idea how to make 24c-16c into kW. I dont understand any of this either.
"Using, as an example, +5 C as the living room or LR temperature and +30 C as the outside air temperature, the maximum Carnot cycle COP is only 278 / (303-278) = 11.12 = Q/W, where Q is the amount of heat moved and W is the work required to move it between those two temperatures using the Carnot cycle."
No idea but the input power is different to what is actually converted.
