A refrigerant circulation system includes a control system and an electronic expansion valve. The control system includes a central processing module, a step drive control module, and a drive module. The operation of the electronic expansion valve in the refrigerant circulation system includes an initialization operation stage and a flow adjustment operation stage, and a maximum operation speed of the electronic expansion valve in the flow adjustment operation stage is smaller than or equal to a maximum operation speed of the electronic expansion valve in the initialization operation stage, and a minimum operation speed of the electronic expansion valve in the flow adjustment operation stage is smaller than a minimum operation speed of the electronic expansion valve in the initialization operation stage, so that stable and fast adjustment of the system can be implemented, and the system keeps stable running.

Refrigerant circulation system

An LIN slave node control system, an LIN slave node and a method are provided. The system includes an electronic control part, which includes: an LIN signal detection, reception, and control module, a processing module connected to the LIN signal detection, reception, and control module and an LIN signal transmitting module connected to the processing module; the processing module generates, according to acquired analysis results, control signals for activating the LIN signal transmitting module, and transmits the control signals to the LIN signal detection, reception, and control module, or blocks LIN signal transmitting module and/or processing module control signals; the LIN signal detection, reception, and control module activates the processing module according to awake signals from an LIN bus, activates the LIN signal transmitting module according to the control signals from the processing module, or can block the LIN signal transmitting module and/or the processing module.
