Correction By Refrigerant Piping Length - Mitsubishi Electric CITY MULTI Data Book

7. CAPACITY TABLES

7-3. 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 7-3-1 and 7-3-2, the capacity can be observed. 7-3-3 shows how to obtain the equivalent length of piping.
