New Daikin concealed duct units benefit from inverter fan motor

Story

New Daikin concealed ceiling ducted indoor units featuring inverter driven fan motors in both VRV (FXSQ and FXMQ) and Sky Air (FBQ and FMDQ) product lines reflect the company’s continuing emphasis on energy efficiency and installation flexibility.

DC inverter based units with higher efficiencies

Daikin pioneered the use of DC inverter technology in its compressors, which modulate the speed of the motor to suit system demand, resulting in optimum efficiency and user comfort. Applying the same technology to the indoor unit fan motors results in reductions in energy consumption up to 40%, the FBQ71 model fan for example consuming 113W compared to 181W for the previous model. Also, enlarging the heat exchanger of the unit where possible, further improves efficiency.

The units also offer the Daikin ‘home leave’ function via the wired remote controller, allowing additional energy savings by preventing excessive cooling of unattended rooms in winter.

Easy and flexible installation

The system also provides automatic airflow adjustment via the wired remote controller, thereby fine tuning the airflow to the nominal rate during installation. Thus, calculation of duct dimensions and ESP are no longer as critical to optimum system operation. This results in quicker and easier installation, avoiding multiple manual airflow adjustments of the ducted system. Design flexibility has also increased, with an enlarged range of available external static pressures supported from 50 to 200 Pa for the FXMQ50.

Improved user comfort

A new three step airflow control allows the user to tailor the system for optimum comfort and minimum noise (down to 26 dBA for FXSQ25 and 29dBA for FBQ71). The duct units blend with any interior, with only the intake and exhaust grilles visible. A built-in air filter ensures a constant supply of clean air and an integral drain pump increases system reliability.
