VRF technology divides a building into zones with individual set points customized for occupant usage, typical solar loads, energy efficiency, and comfort. With no need for fossil fuels, an all-electric VRF heat pump or heat-recovery system provides energy-efficient heating and cooling by cycling refrigerant between an outdoor unit and each zone’s ductless or ducted indoor unit. Up to 50 indoor units can connect to a single outdoor unit. By selecting VRF zoning systems and heat pump water heaters, engineers can help developers and owners future-proof buildings for compliance, tenant expectations, and market value.
