Daikin RXYMQ6AYFK VRV APT outdoor unit
The 6 HP-class RXYMQ6AYFK provides cooling and heating through a designed network of Daikin VRV indoor units. Its 870 mm-high, side-discharge casing is intended for apartments and small premises where outdoor-unit space is limited. This model uses three-phase power; confirm the available electrical supply when comparing the AVMK and AYFK versions. HP denotes the VRV capacity class, not electrical input.
Cooling capacity and efficiency
| Model / capacity class | RXYMQ6AYFK / 6 HP |
|---|---|
| Nominal T1 cooling at 35°C | 16.0 kW / 54,500 Btu/h |
| Nominal T3 cooling at 46°C | 14.5 kW / 49,500 Btu/h |
| T1 power input, including indoor units | 4.10 kW |
| T3 power input, including indoor units | 4.90 kW |
| T3 outdoor-unit power input | 4.74 kW |
| EER, T1 / T3 | 3.90 / 2.96 W/W |
| Cooling Seasonal Performance Factor, T3 | 5.35 W/W |
T1 ratings use 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. The catalogue specifies ISO 15042:2011 for cooling ratings and ISO 16358-1:2013/AMD 1:2019 for hot-climate seasonal performance.
Heating and operating limits
| Nominal H1 heating | 18.0 kW / 61,500 Btu/h |
|---|---|
| Heating COP | 4.25 W/W |
| Heating input, including indoor units | 4.24 kW |
| Catalogue cooling operation range | 0 to 54°C |
| Catalogue heating operation range | −20 to 15.5°C |
H1 heating ratings use indoor air at 20°C dry bulb and outdoor air at 7°C dry bulb / 6°C wet bulb. Operating limits do not imply nominal capacity at every temperature; select equipment for the intended design conditions.
Electrical supply, dimensions and refrigerant
| Power supply | 380–415 V / three-phase with neutral / 50 Hz; 400 V / 60 Hz |
|---|---|
| Dimensions H × W × D | 870 × 1,100 × 460 mm |
| Compressor | One hermetically sealed swing compressor |
| Cooling sound pressure | 58 dB(A) |
| Refrigerant / listed unit charge | R-410A / 5.4 kg |
| Liquid connection | 9.5 mm OD, flare |
| Gas connection | 19.1 mm OD, brazed |
The listed refrigerant charge is the catalogue unit charge. Final charge, wiring, protective devices and pipe sizing depend on the complete installation. Allow the specified service clearances and airflow around the outdoor unit.
Compact installation and high-ambient design
The VRV APT range uses a refrigerant-cooled inverter PCB, additional PCB coating and a blue-coated heat exchanger. External static pressure up to 40 Pa allows installation designers to assess louvres or ducted discharge arrangements. Balcony, wall-mounted and stacked arrangements require suitable support and manufacturer installation clearances; the Daikin duplex mounting bracket is an option rather than an included accessory.
Indoor units and controls
The catalogue presents FXAQ-ARVM wall units, FXFSQ-ARV1 round-flow cassettes and concealed ducted indoor options. Match the exact indoor models, capacity indices, controls and piping as a complete VRV system. A permitted connection ratio does not guarantee simultaneous full output from every connected indoor unit.
