摘要
简单介绍了可编程控制器(PLC)的结构组成与工作原理,回顾了PLC在制冷与空调中的研究与应用状况。并结合某高校制冷与空调实验室对PLC控制系统做了具体地介绍,包括PLC控制环境间温湿度、恒温水箱温度、循环水流量等。可为PLC在制冷与空调测试系统中的应用提供参考。
This paper introduced the compositon and working principle of Programmable Logic Controller（PLC）. The research and application situation of PLC were also reviewed in this paper. In the next, combined with a refrigeration air-conditioning experiment equipment, the application of PLC was introduced in detail,including using it to control the humiture, temperature of constant temperature water tank and circulating water flow. This article research can provide valuable reference for the application of PLC in the measurement system of refrigeration and Air- Conditioning.
