Icing problem
hi! good day to everyone!
We had encountered on 40 tons DX here in the philippines. Total pipe length about 180 feet long (ACCU on roofdeck and AHU on 9th floor of the building).
The problem is:
1. Icing starts when the refrigerant charge riched to 44 psi,
2. What is the posible solution?
3. Piping sized = suction line 2 5/8
= liquid line 1 3/8
