Correction By Piping Length - Mitsubishi Electric City Multi PURY-M200YNW-A1 Data Book

8. CAPACITY TABLES

8-3. Correction by piping length

A decrease in cooling/heating capacity will occur due to piping length increase. Using the following correction factors according to
the equivalent length of the piping shown at 8-3-1 and 8-3-2 the capacity can be calculated. 8-3-3 shows how to obtain the equiv-
alent length of piping. Refrigerant piping and water piping have separate correction factors.
