Daikin FXMQ250NVE6 concealed ducted VRV indoor unit
The FXMQ250NVE6 is part of the FXMQ-NVE6 ceiling-mounted ducted range. Its 28 kW net cooling and 31.5 kW net heating ratings support selection for larger indoor zones served through a duct network. The unit is concealed above the ceiling, with room air delivered through separately designed ducts and grilles. Match the capacity, fan performance and service clearances to the project requirements.
Cooling and heating specifications
| Indoor model | FXMQ250NVE6 |
|---|---|
| Net cooling capacity | 28 kW / 95,500 Btu/h |
| Net heating capacity | 31.5 kW / 107,000 Btu/h |
| Manufacturer capacity class | 10 HP |
| Indoor power input, cooling / heating | 1.650 / 1.650 kW |
Cooling ratings use 27°C dry bulb / 19°C wet bulb indoors and 35°C dry bulb outdoors. Heating ratings use 20°C dry bulb indoors and 7°C dry bulb / 6°C wet bulb outdoors. Both use standard external static pressure, 7.5 m equivalent piping length and zero level difference. Capacities include indoor fan motor heat. Indoor power input is not the electricity consumption of the complete VRV system.
Airflow, duct pressure and acoustics
| Airflow, high / low | 80 / 73 m³/min |
|---|---|
| Sound pressure, high / low | 49 / 47 dB(A) |
| Published external static-pressure settings | 190 / 270 Pa |
| Fan | Direct-drive sirocco fan |
| Temperature control | Microprocessor thermostat for cooling and heating |
Static pressure is selected by changing connectors inside the electrical box, as described in the databook. Check the fan-performance curves against the complete duct resistance; the listed ESP excludes pre-filter pressure drop. Sound levels are anechoic-chamber conversion values measured 1.5 m below the unit centre. Installed sound levels may be higher because of the surrounding conditions.
Dimensions and connections
| Indoor body H × W × D | 440 × 1,490 × 1,090 mm |
|---|---|
| Unit mass | 130 kg |
| Electrical supply | 1 phase, 230 V, 50 Hz |
| Liquid pipe | 9.5 mm, flare connection |
| Gas pipe | 22.2 mm, brazing connection |
| Drain pipe | 31.5 mm diameter steel pipe |
| Casing | Galvanised steel plate |
| Refrigerant control | Electronic expansion valve |
The supplied databook identifies NVE6 as the India-market 230 V, 50 Hz version. Use this exact electrical specification when selecting the unit. Body dimensions do not include the full space required for suspension, duct connections, drainage and service access; refer to the dimensional drawings before installation.
Filter arrangement and system selection
The air-filter specification is listed as optional, and the notes call for a suction-side duct filter with at least 50% dust collection efficiency by the stated gravity method. A pre-filter is also named in the accessories list. Confirm the supplied filter arrangement and include its resistance in the duct design. The databook lists a fuse, over/under-voltage protection and fan-motor thermal protection.
