Daikin has unveiled an inverter-driven rooftop heat pump offering 7.5-ton to 10-ton capacities. The system uses difluoromethane refrigerant and reportedly achieves a coefficient of performance of up to 3.85 at 8.3 C
Daikin Comfort Technologies North America, a unit of Japanese heating system manufacturer Daikin, has launched the Nexio Max, an inverter-driven packaged rooftop heat pump designed for light commercial buildings. The new system targets building electrification projects and combines a variable-speed scroll compressor with difluoromethane (R-32) refrigerant.
The heat pump is offered in 7.5-ton (90,000 Btu/h), 8.5-ton (102,000 Btu/h) and 10-ton (114,000 Btu/h) cooling capacities. Depending on the model, it delivers an Integrated Energy Efficiency Ratio (IEER) of 21.0 to 22.0 and Energy Efficiency Ratio (EER) ratings of 12.1 to 12.4.
The heating performance includes a coefficient of performance (COP) of up to 3.85 at 8.3 C, while the units provide between 63,000 Btu/h and 80,000 Btu/h of heating capacity at -8.3 C with a COP of 2.5.
According to Daikin, the unit can operate in ambient temperatures as low as -25 C and maintains 85% of its rated heating capacity at -10 C, enabling operation in cold-climate applications.
