The invention relates to a cooling system with a variable working condition adjusting function for fluid, the cooling system comprises an expansion machine, a compressor driven by a motor, a controller and a sensing device, the rotating speed of the motor is adjustable, and the sensing device is configured to be used for detecting the temperature of the fluid and/or a cooling working medium. The controller can receive data of the sensing device, and can control the rotating speed of the motor based on the data of the sensing device, so that the temperature of the cooled fluid can be kept at a preset value by adjusting the rotating speed of the motor when the required cooling capacity of the cooled fluid and/or the cooling capacity provided by the refrigerant changes; according to the control method of the cooling system, control is particularly conducted in a PID adjusting mode, the control method has the advantages of being easy to control, safe, reliable and rapid in adjustment, the cooling system can correspondingly adjust the cooling capacity along with changes of the working conditions, and variable working condition adjustment with the cooling capacity range being 0-100% is achieved.

    本发明涉及一种用于流体的具有可变工况调节功能的冷却系统,冷却系统包括膨胀机,由电动机驱动的压缩机,电动机的转速是可调的,还包括控制器和传感装置,传感装置被配置用于检测流体和/或冷却工质的温度,控制器能够接收传感装置的数据,并能够基于传感装置的数据来控制电动机的转速,进而能够在被冷却流体的需求冷量和/或制冷工质所提供的冷量发生变化时,通过调节电动机的转速,进而能够保证流体被冷却后的温度保持在预定值;特别地是通过PID调节的方式来进行控制,具有控制简单、安全可靠、调节迅速的优点,能够使得本发明的冷却系统能够跟随工况的变化而对应地调整冷量,实现冷量范围为0—100%的变工况调节。
