8. Performance Curves
(1) Calculation method of cooling capacity
----cooling capacity to be known = cooling capacity*(A*B*C*D*E) W
E. Capacity compensation value of pipe
length, pipe diameter and height drop
C. Capacity modication value under
airow ariation rate of indoor unit group
(only for duct unit)
A. Capacity compensation value of indoor
air wet-bulb temperature condition
B. Capacity compensation value of outdoor
air dry-bulb temperature condition
D. Capacity compensation suitable for
total capability of indoor unit group
