6-3. Correction by refrigerant piping length
CITY MULTI system can extend the piping flexibly within its limitation for the actual situation. Yet, a decrease of cooling/heating
capacity could happen correspondently. Using following correction factor according to the equivalent length of the piping shown at
6-3-1 and 6-3-2, the capacity can be observed. 6-3-3 shows how to obtain the equivalent length of piping.
