previous article: " most fridges thrash their temperatures " [1]. I've monitored a second fridge.  This isn't that useful until I note which fridge it is.  In the meantime, I think it's either Bosch, Miele or Gorenje. Again, the range of temperature is too big.  It's going from 2 to 9 degrees. The cycle is much shorter: 1h40m, whereas the fridge from the previous article was around 5h. Again, the fridge has only one knob. [1] < https://www.blogger.com/blog/post/edit/3352794691445397639/7027525752784497069 >

most fridges thrash their temperatures

Have you ever wondered what goes on in your fridge when the door is closed? The answer is probably not that the light secretly stays on, but that the temperature fluctuates biglier than you expected, and over a longer period (and the humidity plummets along with temperature while the refrigeration runs). Using logging bluetooth temperature-and-humidity devices, specifically the Sensorpush HTP.xw, I have measured this for three domestic fridges.  They all showed something like the above, which is for a Bosch unit left in a kitchen by a previous owner of a house. The sensor was placed on a shelf, near the top, and near the back, but not touching. The temperature ranges, with period of around 5 hours, from around 2.5 degrees to around 11 degrees.  This is a big range, 8.5 degrees, and the max, 11 degrees, is too hot.  I would be happy with a range of, say 2-5 degrees, but even that seems big.  What's the startup cost to the "refrigeration circuit", or, why would enginee...
