Energy savings

Daikin further improved the energy efficiency and realised substantial energy savings compared to conventional models by achieving a high COP of over 4 for both cooling and heating operations.

Swing Compressor

Thanks to its smooth rotation, the swing compressor decreases friction and vibration. It also prevents the leakage of refrigerant gas during compression. These advantages provide quiet and efficient operation.

The swing compressor can reduce operational vibration and sound because its piston moves smoothly inside the compressor.

Reluctance DC motor and DC fan motor

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.

DC Motor for Fan

The DC motor allows fine rotation control, which reduces energy consumption. The motor also provides improvements in operational efficiency of up to 40%, compared to an AC motor.

Note: Data are based on studies conducted under controlled conditions at a Daikin laboratory.

PAM control

Pulse Amplitude Modulation (PAM) control reduces energy loss by controlling how often the converter switches on and off.
