Design of Mini VRF SYSTEM
1. Model Selecting and Capacity Calculator
(E) Capacity correction for the indoor unit temperature conditions (kW)
From the graph of indoor capacity characteristics on page “ 2-11 ”, read the capacity correction coefficient for indoor unit
temperature conditions.
(H) Capacity correction coefficient for tubing length and elevation difference (%)
From the graph of capacity change characteristics resulting from tubing length and elevation difference on page “ 2-11 ”,
read the capacity correction coefficient.
(E) = Capacity correction coefficient for indoor unit temperature conditions × Rated capacity
(F) Calculate the Capacity distribution ratio (%)
(F) =
(E)
(E)
(G) Distribute the outdoor unit capacity among each indoor unit (kW)
(G) = (A) × (F) × rated capacity of outdoor unit (kW)
2. Indoor unit capacity correction coefficient
Indoor unit capacity correction (kW) = (G) × (H) × (C) × (D)
