AI Technical Summary
The operating range of existing refrigeration compressors is limited, resulting in unstable operation and difficulty in maintaining high efficiency under different operating conditions.
By introducing a cooling mechanism into the refrigeration unit, the refrigerant discharged from the condenser is used to cool components such as the motor, bearings, and controller. The refrigerant supply target position is switched by a control valve, which expands the operating range of the compressor and suppresses problems such as surge and excessive motor temperature.
It effectively expands the operating range of the compressor, suppresses problems such as surge and excessive motor temperature, and improves the operational stability and efficiency of the refrigeration unit.
