1,200%
That's 2× as efficient as a large office chiller, while the theoretical limit for a 20 °C lift is 1.22× more efficient. Every kWh of electricity moves 12 kWh of heat.
What it means
How efficient is that?
These are steady-state ratings. Seasonal figures such as SEER and SCOP average over a whole year of weather and cannot be converted exactly from a single rating.
The math
How to convert COP to %
To convert coefficient of performance to percent efficiency, multiply by 100.
Example: 12 COP × 100 = 1,200 %.
In the other direction, 1 % = 0.01 COP.
