PLC在船舶制冷系统优化设计中的应用

The Application of PLC to Refrigeration System of Vessel′s Optimal Design

介绍船舶制冷系统的工作原理,提出了用可编程序控制器替代继电接触器控制电路,设计压缩机的轻载起动,即避免船舶电网因负载过大而引起电网波动,又进行了能量的调节,提高了系统运行的经济性。

Introduce the working principle of the refrigerating system of vessel, put forward the theory of using the Relay Contractor controlling circuitry instead of Programmable Logic Controller, design the low load starting of compressor,avoid the variation of electric fence of vessel due to high load and at the same time condition the energy and enhanc the economy of the energy operation.
