中央空调水系统变频节能的硬件开发

Hardware Development of Frequency Conversion and Energy Saving of Central Air Conditioning System

主要目标是实时收集中央空调水循环中主要运行参数,通过一定的内部控制逻辑,动态地实现水泵、风机等设备的变频(变流量)调节,最大限度地减少中央空调水循环的能量浪费。采用该方案的中央空调系统,预计可实现水泵节能30%左右,主机节能达到5%~20%。

The paper is based on a practical application on embedded system.The project objects to collect operating parameters real-timely in central water system of air-conditioning(for short: WCCAC),dynamically adjust the working frequency of water pumps and fans though some internal control logic and finally reduce the whole energy consumption to a maximum.Using the plan in WCCAC,it is expected to realize bump energy saving about 30%,main engine 5%~20%.
