摘要
冷却塔被广泛地应用于中央空调的冷却水系统,研究冷却塔的节能是实现中央空调总体节能中不可忽视的任务。介绍了一种由PLC与变频器在冷却塔节能系统中的应用;分析了冷却塔风机变频调速的节能原理,以及PLC控制下变频调速系统和控制过程。
The cooling tower is widely used in cooling water system of central air-conditioning, The save energy of cooling tower is an innegligible role to achieve central air conditioning overall saving. The application of PLC and frequency converter in the cooling water saving energy were introduced in details, It analysed the energy saving principles of frequency converter speed fan for cooling tower, and its speed-adjusted system and its process under PLC controls.
