1.3 Product features
 Super match
By integrating intelligential technology of Haier A/C group, super match air conditioner,
with universal indoor and outdoor units, make more intelligent and flexible choices on
purchasing, easier inventory management to every customer.
 Good for choice
Multi-choice of capacity and appearance of indoor unit according to various rooms.
 DC scroll compressor
The highly efficient scroll compressor is equipped with a “flexible Mechanism” that
allows movement in the axial direction of the frame supporting the cradle scroll. This
greatly reduces both leakage and friction loss, ensuring very high efficiency
throughout the speed range.
 DC inverter technology
Powerful startup: Haier DC inverter system can startup and running at maximum
frequency very quickly in order to reach the set temperature in the shorter time, which
brings you great comfort experience.
Minimum running: Haier DC inverter system will reduce the frequency and running
smoothly according to the real load after reach the set temperature. The system
funning cost reduced drastically which brings you real benefit of money saving.
 Automatic control
Precise control: The temperature sensor can measure the temperature precisely with
only 0.5℃ tolerance, which transfers the exact requirement to the system to adjust the
compressor frequency accordingly.
Once reach the set temperature, the system adjust the frequency smoothly according
to the real time request and always maintain the temperature without fluctuation.
 Wider operation range
Haier DC inverter system provide much wider working range that is suitable for
special cooling, heating requirement.
The Unitary Smart DC inv. outdoor unit default production with AC fan motor, DC fan
motor is for optional choice with additional cost.
