Abstract: A heat pump system includes a compressor, a fluid switching device, a first heat exchanger, a second heat exchanger, a third heat exchanger, a fourth heat exchanger, a flow regulating device and a throttle element. The second heat exchanger includes a first heat exchange portion and a second heat exchange portion. An outlet of the first heat exchange portion communicates with the throttle element. An inlet of the first heat exchange portion communicates with at least one of a second port of the third heat exchanger and an outlet of the fourth heat exchanger. An inlet of the second heat exchange portion communicates with the outlet of the first heat exchanger. An outlet of the second heat exchange portion communicates with an inlet of the compressor. In a heating mode, the function of the second heat exchanger is reduced, thereby the heating capacity of the heat pump system is improved.

Abstract: A control system and a control method, used for controlling a motor. The control system includes a central processing module and a drive control module. In a period in which a voltage is not applied to any phase coil of the motor, the drive control module collects voltages of the phase coil, converts the voltages of the coil into digital signals and stores the digital signals. The central processing module reads the digital signals from the drive control module, accumulates the digital signals to obtain an accumulated value, and determines the operating condition of the motor according to a relationship between the accumulated value and a preset threshold, thereby improving the reliability of the motor control.
