•
Superlink models (not Superlink- models)
•
The KX4 heat pump 2-pipe systems offer high performance VRF
for applications that require either cooling only or heating only.
•
Connect up to 20 indoor units/up to 130% capacity.
•
High efficiency with COP (in cooling) from 3.6 to 3.9.
In case an outdoor unit is installed inside the building
and outdoor exhaust air is discharged to outside the
building through duct system, these units have
necessary minimum external static pressure (50Pa).
