Refrigeration equipment, control method, control device, medium and control system

The invention provides refrigeration equipment, a control method, a control device, a medium and a control system. The control method of the refrigeration equipment comprises the steps that whether a box door is closed or not is judged; if not, returning to the step of judging whether the box door is closed or not; if yes, the high-voltage electrostatic field is opened, and the electrostatic discharge assembly is closed; the timing assembly starts timing; judging whether the box door is closed; if not, the high-voltage electrostatic field is closed, the electrostatic discharge assembly is started, the timing assembly stops timing, and the step of judging whether the box door is closed for the first time continues to be executed; if yes, whether the timing duration is larger than the first preset duration or not is judged; if not, continuing to execute the step of judging whether the timing duration is greater than the first preset duration; if yes, the high-voltage electrostatic field is closed, and the electrostatic discharge assembly is closed; and the timing assembly stops timing. The high-voltage electrostatic field in the electric field auxiliary chamber is opened and closed by controlling the high-voltage electrostatic field assembly, so that the fresh-keeping time of refrigerated and frozen food is prolonged.
