Higher Efficiency & More Energy Saving

Through setting temperature lower limit in cooling or drying mode, and setting temperature upper limit in heating mode, the system is able to operate in a smaller temperature range so as to achieve energy saving. Besides, the unit has got the following energy-saving technologies

The indoor unit and outdoor unit adopt high-efficiency DC brushless motor. The efficiency of such motor will be improved by over 30% compared with conventional AC motor. Therefore, the energy efficiency of the entire unit will be improved by 15% under low frequency operation.

The unit adopts high-efficiency DC inverter compressor self-developed by Westinghouse. The high-efficiency DC inverter compressor self-developed by Westinghouse adopts 180° sine wave space-vector inverter driving technology, so as to realize reliable and stable operation in the frequency as low as 10Hz.

180° Sine Wave Technology

Westinghouse advanced DC inverter 180º vector control ensures the stable operation for compressor, energy-saving up to 20% per year (compared with the common air conditioner).

Precise Temperature Control Technology

Westinghouse intelligent inverter control delivers the required capacity according to the load variation from 10% to 120% and maintains the room temperature within 1℃ of set temperature.
