Abstract
A method for monitoring a surge in a fluid device and a refrigeration system. A fluid device is disposed in an operating unit. The method includes providing and displaying a surge line of the fluid device, where the surge line is at least related to a characteristic between fluid pressure and a flow rate of the fluid device; based on preset time intervals, sequentially providing and displaying operating points, of the fluid device in a current operation condition, in a coordinate system to which the surge line belongs, and when a quantity of the provided operating points exceeds a preset value, removing the first provided operating point therein, so that a quantity of the remaining operating points is the preset value; and monitoring a surge status of the fluid device according to relative position relationships between the displayed operating points and the surge line.
