Control device and control method for compressor of supercooled water unit with variable frequency control

The invention discloses a control device and control method for a compressor of a supercooled water unit with variable frequency control. The control device comprises a frequency converter, a touch screen, a controller, a control relay, a temperature sensor, a pressure sensor and a flowmeter, and the temperature sensor, the pressure sensor and the flowmeter are installed on a supercooled water unit. The whole system is controlled by an intelligent and automatic control system; a humanized human-computer interaction interface is built, and PID energy adjustment is carried out according to the refrigerating capacity requirement of operation of the supercooled water unit. And automatic adjustment and operation are carried out along with the change of the load and the change of external conditions, and manual operation and adjustment are not needed. 本发明公开了一种变频控制的过冷水机组压缩机控制装置及控制方法，控制装置包括变频器、触摸屏、控制器、控制继电器，以及安装在过冷水机组上的温度传感器、压力传感器、流量计，整个系统控制采用智能化、自动化的控制系统，搭建人性化的人机交互界面，根据过冷水机组运行的制冷量需求,进行PID能量调节。并随负荷变化和外部条件的变化自动进行调节和运行
