摘要
从节能的角度,综述制取环境温度以下到-18℃,-18^-60℃,-60^-100℃3个常用温度区间所对应的高效制冷系统,并且从制冷能效角度分别对单级压缩循环、双级压缩循环、复叠式及自复叠式压缩循环进行分析比较;概述PLC控制、传感器、上位机软件等自动化技术,提出冷库自动化对实现冷库节能的重要性及冷库自控技术未来发展的趋势。
In recent years,the energy consumption of our country is becoming more and more serious,and the energy consumption of cold storage occupies a considerable proportion in that of all industries. Therefore,it has become more and more important to reduce the energy consumption of cold storage. The energy conservation,the efficient refrigerating system of three commonly used temperature range with -18 ℃ and above,-18 to -60 ℃,60 ℃ to 100 ℃ was summarized in this review,respectively,and the single-stage compression cycle,two-stage compression cycle and cascade and auto cascade compression cycle several commonly used refrigeration cycle from the perspective of energy consumption were also analyzed and compared. In addition to the PLC control,and a variety of cold storage sensor, PC software automation technology were summarized,which led to the importance of cold storage and its automation control technology,and the future development trend of energy saving of cold storage was also proposed.
