2. Features of 3WAY VRF SYSTEM
System example
* Panasonic makes it possible to link outdoor
unit together for a large capacity (24-Ton).
Since all pipings are concentrated
into one pipe shaft, you can minimize
piping space and construction labor

System limitations
If the additional installment of outdoor and indoor units are
expected, the size of refrigerant piping should be decided
according to the total capacity after the addition.
Maximum tonnage of combined outdoor units
Maximum number of connectable indoor units
Indoor/outdoor unit capacity ratio
Maximum level difference (when outdoor unit is lower)
Maximum total piping length
164 (131) ft
If indoor/outdoor units need servicing, a ball
valve (field supply) cuts off non-operational
units to let other units stay running.
If your indoor capacity load changes in the future, it’s easy to
add on both indoor and outdoor units using the same pipings.
