I got a call one time from a fellow who owned an old

condensing unit off top of the fridge (in the

cool. I was pleased to do that, and he was pleased
with the lower energy bills.


How could he possibly see a difference in an electric
bill for an old age home due to where the condensing
unit was located or even if there was a fridge at all?
Unless it was metered separately, it would be lost in
the noise.

Lower ambient temp means the unit works less.


That isn't the issue. I agree that with lower ambient temp
it's going to use less energy. The issue is how the operator
would see that difference in an electric bill for an old age
home. Presumably there are a lot of other loads, the bill is
likely substantial and the small difference would be lost in the
noise.

Also, it's a different situation from a home. In a commercial
kitchen getting rid of excess heat is likely a good thing all
the time, because the kitchens get uncomfortably hot. In a house,
for about 6 months of the year, the heat from a fridge is essentially
free heat to help heat the house and if you get rid of it outdoors,
it's lost.
to waste.
