蒸汽型溴化锂吸收式冷水机组电脑控制器下位机设计

The Design of a Low Unit of Computerized Controller for the Steam LiBr Absorption Liquid Chiller

本文介绍了蒸汽型溴化锂吸收式冷水机组电脑控制器下位机的软硬件开发设计。合理的多路温度采集电路设计,增强了温度检测的可靠性。液位检测采用交流电流流过溴化锂溶液电极方式测量,解决了直流引起电极腐蚀的问题。

This paper mainly presents the hardware and software design of the lower unit of the controller for steam LiBr Absorption liquid chiller. The valid multicnannel circle design enhances the reliability of temperature measurement liquid level measurement which makes use of the method of alternating current flow through the LiBr solution with electrode, which has solved electrode corrosion problem caused by direct current.
