Correction By Refrigerant Piping Length - Mitsubishi Electric CITY MULTI PUHY-P72-432TNU-A Data Book

8. CAPACITY TABLES

8-4. Correction by refrigerant piping length

CITY MULTI system can extend the piping flexibly within its limitation for the actual situation. However, a decrease of cooling/
heating capacity could happen correspondently. Using following correction factor according to the equivalent length of the piping
shown at 8-4-1 and 8-4-2, the capacity can be observed. 8-4-3 shows how to obtain the equivalent length of piping.
