Daikin FXFQ80B VRV round-flow cassette
The FXFQ80B (FXFQ80BVEB) is a ceiling cassette indoor unit for a designed Daikin VRV system. Its round-flow discharge distributes air around the panel, while individual flap control helps adapt airflow to the room layout. At 9 kW nominal cooling and 10 kW nominal heating, this capacity class can be compared with the other FXFQ-B models when selecting equipment for the room load.
Cooling and heating performance
| Listed model / full databook model | FXFQ80B / FXFQ80BVEB |
|---|---|
| Total cooling capacity | 9 kW |
| Sensible / latent cooling | 6.5 / 2.5 kW |
| Heating capacity | 10 kW |
| Indoor-unit power input, high fan speed | 90 W (specification table, cooling and heating) |
These are high-fan-speed nominal ratings. Cooling conditions are 27°C dry bulb / 19°C wet bulb indoors and 35°C dry bulb outdoors. Heating conditions are 20°C dry bulb indoors and 7°C dry bulb / 6°C wet bulb outdoors. Indoor-unit input is not the power consumption of the complete VRV system. Available capacity depends on the outdoor unit, connected indoor combination, piping and design conditions.
Airflow and sound
| Cooling airflow H / M / L at 50 Hz | 23.3 / 19.2 / 13.5 m³/min |
|---|---|
| Cooling sound pressure H / M / L | 38 / 34 / 30 dB(A) |
| Fan | One turbo fan; five speed steps |
| Filter | Resin net |
Airflow figures above are for cooling; refer to the databook for heating airflow and sound spectra. Sound pressure is measured under specified test conditions and can vary with the installed room and background noise.
Dimensions, electrical supply and pipe connections
| Indoor body H × W × D | 246 × 840 × 840 mm |

Body dimensions exclude the decoration panel. Use the dimension drawings and installation instructions to allow for the panel, ceiling opening, drainage and service access.
Panels, controls and installation options
The databook lists standard, automatic filter-cleaning and designer decoration panels. Intelligent presence and floor sensors, automatic filter cleaning and fresh-air intake are optional configurations, rather than standard features of every supplied unit. Branch duct discharge can be assessed for suitable room layouts. Confirm the exact panel, controller and accessory combination for the project.
The standard BYCQ140E2W1 / BYCQ140E2W1W / BYCQ140E2W1B panel family is listed at 65 × 950 × 950 mm and 5.5 kg. Other panel families have different dimensions and weights. Existing colour choices on this product page should be checked against the agreed panel specification.
Selecting an FXFQ-B indoor unit
Compare Daikin VRV equipment by room cooling load, available ceiling space, airflow and sound requirements. Confirm the exact outdoor-unit compatibility and connected capacity before ordering; an indoor unit alone is not a complete air-conditioning system. The original 29-page FXFQ-B technical databook is available in Technical Downloads, including capacity tables, dimensions, electrical data, wiring diagrams and airflow patterns.
