Daikin FXAQ25A VRV Air Conditioning Indoor Unit – 2.8 kW

Daikin FXAQ25A VRV indoor unit

The Daikin FXAQ25A is a wall-mounted indoor unit designed for use with compatible Daikin VRV air-conditioning systems.

With a nominal 2.8 kW cooling capacity and 3.2 kW heating capacity, the FXAQ25A provides heating and cooling for appropriately sized commercial and other compatible applications. Daikin lists FXAQ25A within its FXAQ-A range of VRV wall-mounted indoor units.

The unit is particularly useful for spaces where a ceiling-mounted indoor unit is unsuitable or where there is limited free floor space.

Daikin FXAQ25A VRV Indoor Unit

The FXAQ25A is part of Daikin’s FXAQ-A family of wall-mounted VRV indoor units.

Daikin describes the FXAQ-A as suitable for rooms without false ceilings and without available floor space, making the wall-mounted format useful for refurbishment projects and commercial installations.

Its flat front panel is designed to integrate with different interior environments, while the unit can be installed in both new-build and refurbishment projects.

2.8 kW Cooling Capacity

The Daikin FXAQ25A provides a nominal cooling capacity of 2.8 kW.

This capacity makes it suitable for appropriately sized rooms and zones within compatible VRV installations.

The required capacity should be determined based on the actual cooling load of the space rather than room size alone.

Factors that can affect the required capacity include:

• Room dimensions
• Insulation
• Windows and glazing
• Solar exposure
• Occupancy
• Lighting
• Equipment and heat sources
• Building orientation
• Local climate

Daikin’s European technical documentation specifies 2.8 kW nominal cooling capacity for FXAQ25A.

3.2 kW Heating Capacity

The FXAQ25A also provides a nominal 3.2 kW heating capacity.

This allows the compatible VRV system to provide both cooling and heating where supported by the connected outdoor system and installation configuration.

Daikin’s European catalogue lists 3.2 kW nominal heating capacity for FXAQ25A.

Wall-Mounted VRV Indoor Unit

The FXAQ25A uses a wall-mounted design, making it an alternative to ceiling-mounted VRV indoor units.

This can be particularly useful in:

• Offices
• Retail spaces
• Hotels
• Commercial rooms
• Refurbishment projects
• Rooms without suspended ceilings
• Spaces with limited floor area

Daikin specifically positions the FXAQ-A range for rooms without false ceilings or free floor space.

Air Distribution

The FXAQ-A range is designed to distribute conditioned air comfortably through adjustable discharge angles.

Daikin states that the air can be distributed upward and downward using five different discharge angles, programmable through the remote control.

This gives installers greater flexibility when positioning the unit for a particular room layout.

Compact Wall-Mounted Design

The FXAQ25A has a relatively compact wall-mounted form factor.

Daikin’s documentation lists the FXAQ25A dimensions at approximately:

290 mm H × 795 mm W × 266 mm D

and a unit weight of approximately 12 kg.

This makes the unit suitable for installations where a wall-mounted solution is preferred.

Quiet Operation

Daikin’s European specifications list the FXAQ25A at approximately 36 dB(A) high fan speed and 31 dB(A) low fan speed for the applicable specification.

Actual sound levels can vary depending on operating conditions and installation.

Daikin VRV Compatibility

The FXAQ25A is a VRV indoor unit, not a conventional standalone split-system indoor unit.

This distinction is important when purchasing.

The indoor unit must be matched with a compatible Daikin VRV outdoor unit and control system according to Daikin’s approved combination requirements.

Before purchasing, installers should verify:

• VRV outdoor-unit compatibility
• Refrigerant piping requirements
• Control requirements
• Indoor-unit combination
• Installation conditions
• Electrical requirements
• Applicable accessories

Commercial Air Conditioning Applications

The Daikin FXAQ25A can be used in compatible commercial VRV installations.

Potential applications include:

Offices

Provide individual climate control for appropriately sized office spaces.

Retail

The wall-mounted design can be useful in retail areas where ceiling installation is unsuitable.

Hotels

Individual rooms or zones can be climate controlled using a compatible VRV system.

Refurbishment Projects

The FXAQ-A design can be useful where a false ceiling is unavailable.

Commercial Buildings

Multiple indoor units can form part of a larger Daikin VRV installation.

The exact application should be assessed by a qualified HVAC professional.
