I discovered recently that on my domestic refrigerator condenser coil is wrongly conected.
Fridge works perfectly OK except it is noisy (noise comes from evaporator where capilary enters).

Here some pisctures:



I wonder why is it works OK while at capillary entrance it doesn't have liquid refrigerant.
It is puzzling to me and I like to know what is happening and if my fridge is not efficient as it should be (no subcooling).
Not that I want to change anything untill it devolop some other problem.

Any insight or comment from "capillary" experts?
