The ice storage central air-conditioning system

due to its large number of equipment

complex working conditions

and high requirements for control accuracy

usually adopts programmable control technology to construct a group control system for overall control. This system is composed of equipment such as frequency converters

PLCs

input/output modules

temperature sensors

pressure sensors

liquid level sensors

and temperature modules. It realizes interaction and monitoring between operators and the control system through the human-machine interface and host computer system

ensuring that the central air-conditioning control system achieves automatic control and optimized operation.
