Correction By Refrigerant Piping Length - Mitsubishi Electric CITY MULTI PEFY-P22VMS-E-S Data Book

6. CAPACITY TABLES

6-3. Correction by refrigerant piping length

CITY MULTI systems can have extended piping lengths if certain limitations are followed, but cooling/heating capacity could be
reduced. Using following correction factor by equivalent piping length shown at 6-3-1 and 6-3-2, capacity can be found. 6-3-3
shows how to obtain the equivalent piping length.
