I hear ya MarkP but my old fridge ( and my Helco Bill ) stay lower filled vs. empty.
Terracore, if you have time and want to torture yourself ... Look into thermal mass more ... Your teenager for sure makes a difference between full vs. empty.
Cut and paste food for thought.
Yes it takes more energy to perform a cooling cycle when the fridge is full, but a full fridge performs 'less' cooling cycles over time. The average amount of power required for each system is the same, since the system spends the same proportion of time in each temperature state.
Yes it stays colder for longer, but it also stays less colder for longer. This is what Loren what mentioning about how the proportion of time spent in each temperature state is the same for each system. The full fridge just has an elongated charging exponential of T(t), while the empty fridge is squished. But the average value of each curve is the same. At least that's my current thinking. Happy to be convinced one way or the other
