The Smart Alternative
YORK® VWF uses chilled water — not refrigerant — inside your building. That one difference changes everything.
The Core Difference
VRF systems circulate high-pressure HFC refrigerant through pipes that run throughout your building into every room. YORK® VWF generates chilled water at the outdoor unit and distributes only water indoors. This single engineering decision has profound implications for safety, cost, flexibility, and lifespan.
Water operates at 0.6 MPa vs 2.8–3.0 MPa for VRF. No refrigerant leak risk in occupied spaces. No ASHRAE 15 refrigerant concentration concerns.
COP >3.8 at IPLV/NPLV. No piping deration penalty. BMS compatibility standard. Typical 20–35% savings vs VRF in real-world operation.
No piping length limits (VRF maxes at 200m). No IDU count restrictions. Different make indoor units work. Future expansion is modular and simple.
VRF averages 10–12 years. YORK® VWF is built for 20–25 years with lower maintenance frequency and cost throughout its life.
