Commercial CO 2 Refrigeration Systems Guide for Subcritical and Transcritical CO 2 Applications. Just love it!! If the refrigerant piping insulation is intact over its length and not compressed (for example by being squeezed in a hanger strap) you ought not see condensation on that piping run (it's actually condensate - water condenses out of air onto the cooler pipe surface, the pipe isn't really "sweating" as does our skin when it exudes moisture out through its pores). Proper refrigerant feed to the evaporator must be maintained, and excessive pressure drop in the refrigerant piping must be avoided.
