Correction By Refrigerant Piping Length - Mitsubishi Electric PQRY-P72TLMU-A Manual

8. CAPACITY TABLES

8-9. 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 the following correction factor by equivalent piping length shown at 7-3-1 and 7-3-2, capacity can be found. 7-3-3
shows how to obtain the equivalent piping length.
