Correction By Piping Length - Mitsubishi Electric CMB-WP-V-GA1 Data Book

2. CAPACITY TABLES

2-3. 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 2-3-1 and 2-3-2 the capacity can be calculated. 2-3-3 shows how to obtain the equiv-
alent length of piping. Refrigerant piping and water piping have separate correction factors.
