SPLIT-PAK
Has anyone worked on Master-bilt SPLIT-PAK units before that are for both walk in coolers and freezers they share the condenser coil into two different circuits.
I’ve been working on several of them recently for McDonald’s and have been told by my boss and several of my coworkers that for the walk in freezers that use EEV’s you shouldn’t clear the sight glass
I’ve also noticed that they don’t have receivers on them from factory
Also I’ve noticed that if you slightly over or undercharge the system it will not act right and the EEV won’t know what’s going on and keep opening and closing it’s self constantly
Could someone explain in more detail as to why it doesn’t have a receiver? Or why it’s designed that way?
I would assume it’s because the EEV basically it’s acting like a receiver in some sort of way backing up refrigerant when needed and allowing more in based on the superheat which could be the reason the sight glass isn’t fully cleared or having problems when over or undercharged
