Coefficient of Performance (COP)
|
The higher an air conditioners COP the more efficient it is. |
| |
Definition:
Coefficient of Performance is the efficiency ratio of the amount of heating or cooling provided by a heating or cooling unit to the energy consumed by the system. The higher the Coefficient of Performance the more efficient the system. Electrical heating for example has a Coefficient of Performance of 1.0.
What does that mean?
So, if a heating element is giving 2.5kw of heating it is also using 2.5kw of power.
If an air conditioner has a rating of 2.5kw, giving you 2.5kw of cooling, it is only using 0.52kw to achieve that.
2.5 divided by 0.525 = 4.76 (COP) That makes it almost 5 times more efficient than electrical heating. |

Almost all brochures have a spec sheet printed inside.
