摘要
以中央空调节能改造为例,介绍了其节能改造措施及设计方案。构建了温差闭环自动控制系统,以达到自动调节中央空调冷却泵的输出流量,实现降低能耗,提高系统稳定性,延长设备寿命的目的。该方案可为既有设备的节能改造提供思路与参考。
Taking the reconstruction of the central air-conditioning energy saving as example, the measurement and design scheme of the energy saving modification of the central air-conditioning were introduced. The temperature sensor and temperature module were used to construct a closed loop automatic control system of temperature difference, automatically regulate the output flow of the central air-conditioning＇ s cooling pump, thus it finally realized the purposes of reducing energy consumption, .improving the system stablity and extending the usable life of the equipment. This scheme could supply ideas and references to the existing energy saving modification.
