Step3 – The total indoor capacity connected to a branch pipe port
(or pair of branch pipe ports in case of FXMA200/250) MUST be
equal or less than the capacity limit that is derived from the table.
If NOT, change the installation and repeat all of the above steps.
Possible changes:
▪ Increase the area of smallest room (installed & conditioned)
connected to the same branch pipe port.
▪ Reduce the indoor capacity connected to the same branch pipe
port to equal or below the limit.
▪ Split indoor capacity over two separate branch pipe ports.
▪ Fine tune system with more detailed calculations in VRV Xpress.
Example
VRV system serving three rooms via one SV unit. Room1 (20m²) is
served by one indoor unit (32 class) connected to port A. Room2
(42 m²) is served by two indoor units (2×50 class) connected to
portB (no extension and liquid pipe size up has been done). Room3
(150 m²) is served by one indoor unit (200 class) connected to
portsC and D.
Port A is connected to an indoor unit installed in room 1a, that is
serving a different room (room 1b) than where it is installed. The
smallest room size needs to be considered: 20 m². Use the table
under Step2 to find the maximum capacity class limit of the indoor
unit: 140. The selected indoor unit is 32 →OK.
Port B only serves room2: use the table under Step 2 to find the
maximum capacity class limit of the sum of the indoor units. 42m² is
rounded down to 40m²: 200. The sum of both indoor units is exactly
100 →OK.
PortsC and D are combined and must be considered as one branch
pipe. They only serve room3: Use the table under Step2 to find the
maximum capacity class limit of the indoor unit: 250. The selected
indoor unit is 200 →OK.
