Issue:
Are the inlet and outlet refrigerant lines on a braze plate heat exchanger crisscrossed?
Resolution:
It depends on the Design Sequence of the chiller (Digit 10 in the model number)
For "K" Design Sequence:
This heat exchanger was made by Alfa Laval. The refrigerant lines are crisscrossed. The liquid line (on the bottom) and the suction line (on the top) are not directly over one another for an individual circuit. The liquid lines are crisscrossed on a dual circuit unit. The TXV sensing bulb and equalizer lines should also follow the refrigerant lines.
For "L" Design Sequence and higher:
This heat exchanger was made by SWEP. The refrigerant lines are not crisscrossed. The liquid line (on the bottom) and the suction line (on the top) are directly over one another for an individual circuit. The TXV sensing bulb and equalizer lines should also follow the refrigerant lines.
