Daikin Debuts Improved Commercial Heat Pump Systems
NEW MODELS: The new Daikin VRV Emerion systems are available in capacities from 6 tons to 40 tons.
WALLER, Texas — Daikin Comfort Technologies North America Inc. has introduced the Daikin VRV Emerion commercial heat pump and heat recovery systems, featuring low-GWP R-32 refrigerant.
Building on the success of R-410A commercial VRV (variable refrigerant volume) solutions, Daikin has redesigned these three-phase, air-cooled systems to reduce installation and commissioning times, expand heating and cooling operations, improve energy savings, simplify maintenance, and expand monitoring capabilities compared to the older systems, a Daikin Applied press release said. Daikin R-32 VRV Emerion requires a lower system refrigerant charge compared to VRV Emerion R-410A systems.
“Launching this innovative and versatile R-32 commercial line for North America exemplifies Daikin’s goal to supply advanced, sustainable, and flexible HVAC solutions,” said Sachin Dixit, vice president, commercial strategy and business development at Daikin.
Available in capacities ranging from 6 tons to 40 tons, the VRV Emerion is engineered for increased energy savings with variable refrigerant technology delivering efficiencies of up to 24.6 IEER and 3.80 COP. Evaporation temperature control at each indoor unit provides comfort to each space along with the required branch selector box or safety shutoff valve.
The new VRV Emerion operates in ambient temperatures ranging from -22°F to 122°F. During defrost capability, continuous heating can be provided with single-module (16 to 20 tons) and all dual-module (22 to 40 tons) heat pump and heat recovery systems.
The VRV Emerion with R-32 allows reuse of existing R-410A piping for retrofit applications and includes larger-capacity, single-module units compared to VRV Emerion with R-410A. This helps limit the space required for mechanical equipment while minimizing electrical and piping connections. The systems support up to 361 feet of vertical separation, with possibilities for extending that to 720 feet. For phased installations, systems can be expanded from single- to dual-module without changes to installed main pipe sizes.
The new VRV Emerion cuts installation and commissioning time, compared to VRV Emerion R-410A systems, with an auto-address feature with D4 communications protocol. The new D4 net provides larger data volume and communication speeds up to 30 times faster compared to the D3 net.

A new remote option with HERO Cloud Services enables data retrieval and field-setting changes from virtually anywhere. The built-in recorder stores up to 40 minutes of operational data. Daikin VRV Emerion also integrates with the Daikin HERO Ecosystem, an IoT-based remote monitoring and diagnostics platform.
The drop-down electrical box service window provides quick access to configuration buttons and a digital display showing refrigerant pressures and temperatures. The sealed, IP55-rated electrical box provides high dust and moisture protection. Easy-to-access mechanical, electrical, and airflow sections can be quickly removed. The need for a base pan heater can be eliminated with a hot gas defrost circuit.
For commercial building tenants, inverter-driven, variable-speed scroll compressors help the Daikin R-32 VRV Emerion run quietly — down to 58 decibels.
