We just mount unit for climatisation on big supermarket.The manufacturer sent 4 big evaporators (125 kW cooling pover,1 x 1 in paralel) and 2 TEV s with external equalizer.
We made separation tube and conect then Tev on evaporators inlet.The sensing bulb is located after separation tube at the evaporators outlet (10 cm = 4" from end of separation tube).Used refrigerant is 407c.
I expect problem when heat exchanger gets dirty and asume that superheat level on each evaporator woudnt be equall.

Generaly opinion on this?
