Daikin RXYTQ16U5YF VRV IV+ heat pump outdoor unit
The 16 HP-class RXYTQ16U5YF serves a designed network of VRV indoor units in multi-room and multi-zone buildings. It provides 45.0 kW nominal cooling at T1 conditions and 45.0 kW nominal heating. HP identifies its VRV capacity class, rather than electrical input power.
Cooling capacity and hot-climate efficiency
| Model / capacity class | RXYTQ16U5YF / 16 HP |
|---|---|
| Nominal T1 cooling at 35°C | 45.0 kW / 153,550 Btu/h |
| Nominal T3 cooling at 46°C | 35.1 kW / 119,800 Btu/h |
| T1 power input, including indoor units | 12.64 kW |
| T3 power input, including indoor units | 12.10 kW |
| T3 outdoor-unit power input | 11.71 kW |
| EER, T1 / T3 | 12.15 / 9.90 (Btu/h)/W |
| Cooling Seasonal Performance Factor, T3 | 18.29 (Btu/h)/W |
T1 cooling uses indoor air at 27°C dry bulb / 19°C wet bulb and outdoor air at 35°C dry bulb. T3 uses indoor air at 29°C dry bulb / 19°C wet bulb and outdoor air at 46°C dry bulb, per the catalogue’s ISO 15042:2011 notes. The separate maximum T3 capacity of 38.6 kW applies at 19°C indoor wet bulb, 46°C outdoor dry bulb and a 130% indoor connection ratio, for limited hours. It is not the nominal capacity. The seasonal figure follows the catalogue’s ISO 16358-1:2013/AMD 1:2019 method.
Heating performance and operating range
| Nominal heating capacity | 45.0 kW / 153,550 Btu/h |
|---|---|
| Heating COP | 3.48 kW/kW |
| Heating power input, including indoor units | 12.92 kW |
| Outdoor cooling range | −5 to 55°C dry bulb |
| Indoor cooling range | 14 to 25°C wet bulb |
| Outdoor heating range | −20 to 15.5°C wet bulb |
| Indoor heating range | 15 to 27°C dry bulb |
Nominal heating uses indoor air at 20°C dry bulb, outdoor air at 7°C dry bulb / 6°C wet bulb, 5 m equivalent refrigerant piping and no level difference. Operating limits do not imply nominal output at every temperature; use the project design conditions when selecting capacity.
Variable refrigerant temperature and compressor design
Variable Refrigerant Temperature (VRT) control adjusts refrigerant temperature to changing load and comfort requirements. The VRV IV+ scroll compressor uses back-pressure control to reduce internal refrigerant leakage during low-load operation. A refrigerant-cooled PCB and four-sided, three-row heat exchanger support the outdoor unit’s thermal design. The series also provides a seven-segment service display and supports VRV Configurator commissioning.
Dimensions and electrical requirements
| Power supply | 380–415 V / 3-phase / 50 Hz; 400 V / 3-phase / 60 Hz |
|---|---|
| Refrigerant | R-410A |
| Dimensions H × W × D | 1,685 × 1,240 × 765 mm |
| Catalogue net weight | 283 kg |

Plan the mounting arrangement around the 283 kg catalogue unit weight, service clearances and unobstructed airflow. Refrigerant pipe sizes, additional charge, wiring and protective devices must be selected for the installed system using the applicable engineering and installation information.
Indoor units and system selection
The catalogue lists connections to Daikin VRV indoor families including FXAQ-ARVM wall units and FXFSQ-ARV1 round-flow cassettes, alongside concealed ducted options. Confirm the exact indoor models, combination ratio, controls and piping design as a complete system. Indoor units, controllers and interfaces are not implied to be included with this outdoor-unit listing.
