Unified REFNET piping - VRVII
•
The unified Daikin REFNET piping system is especially designed for simple installation
•
The use of REFNET piping in combination with electronic expansion valves, results in a dramatic reduction in imbalance in refrigerant flowing between
indoor units, despite the small diameter of the piping.
•
REFNET joints and headers (both accessories) can cut down on installation work and increase system reliability.
•
Compared to regular T-joints, where refrigerant distribution is far from optimal, the Daikin REFNET joints have specifically been designed to optimise
refrigerant flow.
