📊 VRF Inverter Diversity (50% to 130% Indoor-to-Outdoor Unit Sizing Connection Ratio)

VRF Indoor Unit Connection Ratio Calculator

Optimize the connection capacity ratio of indoor fan coils connected to a single outdoor VRF inverter condensing unit: calculate diversity factor (sizing connected indoor fan coils up to 130% of outdoor nameplate capacity by taking advantage of solar orientation and non-coincident building peak cooling/heating demands), and VRF equipment sizing yields.
