Fridge temperature depends on ambient

I cut my teeth on lithium bromide liquid absorption chillers. The units are 25' in length, weigh 9 tons, and require a boiler and cooling tower. There wasn't one on the face of the earth that was automated. Even though these systems utilize cooling towers and fans a more change in wind direction required manual adjustments. Note the plural, adjustments...

You do not want to know what happens if the lithium compound overheats.

Now mix in complexity with lowball construction cost versus longevity. Be thankful if your absorption unit performs to your expectations of performance and longevity
