About this file
These are submittal data sheets for two Daikin Variable Refrigerant Volume (VRV) IV heat pump units designed for commercial HVAC applications. The first sheet documents the 12-Ton, 230V VRV IV X HP model (RXYQ144XATJA), while the second covers the 14-Ton VRV-IV Heat Pump Unit model (RXYQ168TTJU), also 230V.
The 12-ton unit (RXYQ144XATJA) delivers rated cooling capacity of 138,000 Btu/hr and heating capacity of 154,000 Btu/hr, with nominal capacities of 144,000 and 162,000 Btu/hr respectively. It operates on 208-230V, 60Hz, 3-phase power with a minimum circuit amperage (MCA) of 55.1A and maximum overcurrent protection (MOP) of 60A. Key performance metrics include cooling EER of 12.10 (non-ducted), heating COP of 3.6, IEER of 24.80, and heating COP at 17°F of 2.3. The unit features an inverter-driven compressor, R-410A refrigerant charge of 18.1 lbs, maximum total piping length of 540 feet with 295-foot vertical separation capability, and supports up to 25 indoor units. Assembled in the United States, the unit includes a 10-year limited parts warranty and operates reliably in cooling ranges of 23-122°F DB and heating ranges of -4 to 60°F WB.
The 14-ton unit (RXYQ168TTJU) provides rated cooling of 160,000 Btu/hr and heating of 180,000 Btu/hr, with nominal capacities of 168,000 and 188,000 Btu/hr. Operating specifications are identical to the 12-ton model regarding voltage (208-230V, 60Hz, 3-phase), with MCA of 55.1A and MOP of 60A. Performance includes cooling EER of 10.60, heating COP of 3.7, IEER of 22.10, and heating COP at 17°F of 2.3. This larger unit holds 17.2 lbs of R-410A refrigerant and supports up to 29 indoor units with the same piping and vertical separation capabilities. Both units emphasize modular design flexibility, integration with gas furnaces, variable refrigerant temperature (VRT) control for improved seasonal efficiency (up to 28% improvement over previous VRV models), easy commissioning through configurator software, and corrosion-resistant heat exchangers with 1000-hour salt spray testing.
