I always get a lot of help here so this time I would like to share once a (I think) unusual experience. Maybe is useful for someone.
I had some issues with my freezer/fridge. The compartments a real big and worked with a spill over from the freezer
to the fridge. When the compressor
stalled I had to buy (based one wrong advice from a local "expert") a new compressor
. Due some valuable forum help I was able the get the old compressor running. Since I had now a new unit as well, I decided to split the system and use one compressor for the freezer
and the other for the fridge. I installed digital Thermostats so I can run whatever side as fridge or freezer.
I was well aware that two compressors need more juice than one. But since we full time cruiser and the fridge is always well filled I was willing to deal with that as I have now some kind of a backup system. Hard to imagine that both systems fail at the same time.
You could imagine how surprised I was when I discovered that I actually saved energy, up to 30A in 24h! First I was sure that must be a mistake so I checked again. At one point it became clear to me, I needed less power for a simple reason: Here in the Caribbean
compressor was running almost 90% of the time to keep the big two compartments at the desired temperature. It was probably simply undersized for this area. Now the compressors runtime is significant less: maybe every 30 - 45min or so!
I know, you could now argue that a better isolation would achieve the same or even more energy saving. For sure! But that would cost more than a new compressor and a evaporator, if you get the right material over here! Despite the fact that it would be a multi week long project
. So, if you depend on the fridge/freezer check if this could be an option for you. I know it will not work for everybody but maybe worth checking - at least it was for me!
