本文介绍的冷库温湿度电脑控制仪，适用于各种类型冷库的温湿度控制。该控制仪主要由ＭＣＳ－５１系列单片机、Ａ／Ｄ转换板、输出控制电路、显示电路、报警电路、测温和测湿器件等组成。温湿度控制范围为：温度－４０℃～＋１１℃±０．５℃；相对湿度０～１００％±２～３％。几年来的试用运行结果表明，利用该电脑控制仪控制冷库的温湿度，控制精度高，库内温湿度波动小，提高了冷冻产品的质量，而且能耗明显降低，平均可节电８～１０％。
This article describes the cold temperature and humidity computer controller for all types of cold storage temperature and humidity control. The controller mainly consists of MCS-51 series microcontroller, A / D converter board, the output control circuit, display circuit, alarm circuit, temperature measurement and humidity measurement devices. Temperature and humidity control range: temperature -40 ℃ ~ +11 ℃ ± 0.5 ℃; relative humidity 0 ~ 100% ± 2 ~ 3%. Trial run over the years the results show that the use of the computer controller temperature and humidity control of cold storage, high control accuracy, temperature and humidity fluctuations in the library is small, improve the quality of frozen products, and significantly reduce energy consumption, an average of 8 to 10 energy-saving %.
