摘要： A gas-liquid separation device includes a cylinder, an external port, an adapter, and a gas-liquid separation component. The cylinder has a first cavity, a second cavity, and a third cavity. The external port includes a first port, a second port, and a third port. The adapter is at least partially disposed in the cylinder. The gas-liquid separation component is located in the third cavity. When the gas-liquid separation device is in a first working state, the adapter separates the third port from the third cavity, the first port serves as the inlet, and the second port serves as the outlet when the gas-liquid separation device is in a second working state, the adapter communicates the third port with the third cavity, the second port serves as an inlet, and the first port and the third port serve as outlets. The gas-liquid separation component separates gas-liquid two-phase refrigerant.

摘要： A control method and a control system, by which a motor can be controlled. 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 coil to which the voltage is not applied, and converts the voltages of the coil into digital signals. The central processing module reads the digital signals and determines whether the running speed of the motor 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.

摘要： 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.

摘要： An electric valve includes a stator assembly, a rotor, a circuit board assembly, a sleeve and a valve assembly. The stator assembly is arranged around the rotor. The sleeve isolates the stator assembly from the rotor. The stator assembly is electrically connected to the circuit board assembly. A valve port is formed in the electric valve. The rotor can drive the movement of the valve assembly with respect to the valve port. The electric valve further comprises a box body. The circuit board assembly is arranged in the box body. The box body includes a shell and a cover body. A seal ring is arranged at a joint of the shell and the cover body. The seal ring is compressed between the shell and the cover body. The cover body is fixedly connected to the shell by means of welding.
