To meet the heating demand in extremely cold weather in northern China, Sonyo Compressor (formerly Panasonic Dalian) has launched a new series ultra-low ambient temperature scroll compressors for air source heat pump application.

The new compressors are featured with following advantages:
1.    Optimized scroll profile and discharge path, allow the compressor to operate for heating in -40℃ ultra-low ambient temperature.
2.    Unique gas injection path design, reduce the injection gas pressure and improve heating efficiency, achieve a stable discharge temperature control.
3.    Patented check valve design for gas injection, increase the refrigerant mass flow, and low down the compressor vibration and noise level.
4.    High efficiency motor with unique cooling solution based on oil and gas separation design, ensure the reliability of motor in severe operation conditions.
