Hiya
I have a flakt woods condensing unit that's on r407c and is 28kw. It has 2 stages which are to be connected to a air handling unit. I need to size for 2 externally equalised TEVs for the application. I know the evaporating temp is obviously 0degrees for the system, do I size for 2 14kw valves? And also iv noticed the different pressure drops across the valve options. Iv always got the standard 8 bar differential for other applications will this still be fine?
personally I think I need 2 TEZ2 valves with number 5 orifaces? Just would like a second opinion.
