Why do you need to observe the bubbles in the sight glass for refrigerant filling? This method does show that there are bubbles that indicate a lack of refrigerant, but we must understand that the pressure loss of the liquid pipe can also cause bubbles. If the pressure loss of the liquid pipe is lar... read more
