BD—105型电冰柜温度控制系统的研究

The Study of the Temperature Controlling System for the Freezer of the Type BD-105

本文以增设ＢＤ—１０５型电冰柜的温度控制系统为例，系统地介绍５５５时基电路在温度控制系统中的应用及控制原理。对安装和调试过程也予以介绍，本控制系统电路也可以用在其它相应的温度控制系统中。

The addition of the temperature control system to the freezer of the Type BD-105 was used as an example to introduce the function of the timer NE555 and its uses in setting up the temperature control system.The installation and adjustment were introduced as well. This system could be used in other temperature control systems.
