Smooth sine wave DC inverter
Use of an optimised
sine wave smoothes
motor rotation,
further improving
operating efficiency.
Daikin DC inverter models are equipped with the Reluctance DC motor for compressor.
The Reluctance DC motor uses 2 different types of torque, neodymium magnet*
1
and
reluctance torque*
2
. This motor can save energy because it generates more power with a
smaller electric power than an AC or conventional DC motor.

*1 A neodymium magnet is approximately 10 times stronger than a
standard ferrite magnet.
*2 The torque created by the change in power between the iron and
magnet parts.
Sucked gas is compressed in
the scrolling part before the
heated motor, so that the
machine compress the
non-expanded gas, resulting
in high efficiency
compression.

New oil receiver
Oil separator
Compressor
Refrigeration oil discharged from the compressor
circulates in the refrigerant cycle and lowers the
heat transfer capabilities of the indoor and outside
unit heat exchangers.
Surplus oil is stored in the oil receiver
and automatically controls the amount of
refrigeration oil in the refrigerant cycle.
This prevents a reduction in performance
for heat exchanger.

Adding a container vessel (Oil Receiver) helps eliminate performance degradation by retaining
refrigeration oil and preventing excessive oil from flowing to the heat exchanger.
The new design enables the oil receiver to automatically supply the compressor with only the
necessary amount of oil.
