pipe lenght vis a vis oil traps
Hey Guys,
Yesterday vbeen on a hitachi HAS-12HNC.Found shorted compressor insulation !! Between the 5 indoors and the top roof level outdoor there are 7 storeys. There is not a single oil trap. Does not consider it normal . what are the views ? VRFs allowable to be a straight pipe or ? I cannot understand how the oil will be pulled up in that height back to compressor. Am I missing something ?
