I'm observing an interesting relationship between outdoor temperature and the energy used by my air conditioning compressor.
The graph below shows:
Y axis = how many watts the compressor is using
X axis = hour of the day
Red line is the compressor cycling. The grey line is outside temperature (F) multiplied by an arbitrary number (45 in this case) to scale it to the Y axis.
I wasn't surprised that the two independent inputs correlate, they should, but what surprised me is just how closely the outside temperature and energy usage tracks each other.
What would be a scientific way to explain what I'm observing?
