design guideline Summary

device Connection limitations
A single-zone ceiling-concealed duct (high static) system consists of one outdoor unit and one indoor unit. One of the most critical elements
of a single-zone ceiling-concealed duct (high static) system is the refrigerant piping. The table below lists pipe length limits that must be
followed in the design of a single-zone ceiling-concealed duct (high static) refrigerant pipe system:
