摘要： An electric valve, comprising a stator assembly (1), a valve component (3), a valve body (4), a first sealing member (5) and a sleeve (9); the stator assembly is located at the periphery of the sleeve and is limitingly connected to the valve body; the stator assembly is provided with a first recessed part (144), which is located between the valve component and the stator assembly; at least part of the opening of the first recessed part faces toward the valve body, and the first sealing member is located in the recessed part. Providing the first sealing member between the stator assembly and the valve component helps, to a certain extent, to reduce the humidity in the exterior environment that enters the stator assembly by means of the gap between the stator assembly and the sleeve.

摘要： A heat pump system includes a compressor (1), a fluid switching device (3), a first heat exchanger (21), a second heat exchanger (22), a third heat exchanger (23), a fourth heat exchanger (24), a flow regulating device (5) and a throttle element (4). The second heat exchanger (22) includes a first heat exchange portion (221) and a second heat exchange portion (222) which exchange heat with each other. An outlet of the first heat exchange portion (221) communicates with the throttle element (4), and an inlet of the first heat exchange portion (221) may communicate with at least one of a second interface of the third heat exchanger (23) and an outlet of the fourth heat exchanger (24). An inlet of the second heat exchange portion (222) communicates with the outlet of the first heat exchanger (21), and an outlet of the second heat exchange portion (222) may be in communication with an inlet of the compressor (1). In a heating mode, the throttle element (4) is closed, and the flow regulating device (5) throttles and depressurizes a refrigerant. Since the function of the second heat exchanger (22) is reduced under heating conditions, the heating capacity of the heat pump system will be effectively exerted.

摘要： A control method and a control system (2), by which a motor (31) can be controlled. The control system (2) comprises a central processing module (22) and a drive control module (23). In a period in which a voltage is not applied to any phase coil of the motor (31), the drive control module (23) collects voltages of the coil to which the voltage is not applied, and converts the voltages of the coil into digital signals. The central processing module (22) reads the digital signals and determines whether the running speed of the motor (31) is consistent with a preset speed depending on whether an average value of the digital signals falls within a preset threshold range, which helps to improve the control precision.
