变风量空调系统自动控制的标准化
Standardization of automatic control for VAV air conditioning systems
摘要：
举例讨论了变风量空调系统自动控制的标准化。变风量空调系统自动控制的标准化打破了仅由自控承包商一家参与并负全部责任的传统行规,让整个暖通空调行业都参与进来并承担主要责任。参与者与责任人的变化对空调系统自动控制工程领域来说可谓是发生了翻天覆地的变革。这场变革也给这个专业领域带来了一场技术革命。它充分利用楼宇自控系统的计算机功能,并结合人类经验和科技,摆脱传统依赖管理人员技术和经验的运营模式,将变风量空调系统的自动控制从简单逻辑控制发展到包括多级自动报警、自动检测缺陷的优化控制,以最大限度地提高空调系统能效和性能、增强控制稳定性,可实施在线故障检测和诊断,达到削减工程时间、减少编程和调试工作量、降低能耗、缩短离线故障检测诊断停机时间等目标。
Abstract：
This article provides an example to discuss the standardization of automatic control for VAV air conditioning systems, which breaks the traditional regulations of only involving self-control contractors and taking full responsibility, and allows the entire HVAC industry to participate and take on the main responsibility. The changes of participants and responsibility can be regarded as a revolutionary change for the automatic control engineering field of air conditioning systems. Meanwhile, this transformation is also a technological revolution. It fully utilizes the computer functions of building automation systems and combines human experience and technology to break away from the traditional operation mode that relies on the technology and experience of management personnel, and develops the automatic control of VAV air conditioning systems from the simple logic control to the optimized control including multi-level automatic alarm and automatic fault detection, in order to maximize the energy efficiency and performance of the air conditioning system, enhance the control stability, and implement the online fault detection and diagnosis, so as to achieve the goals of cutting engineering time, reducing programming and debugging workload, lowering energy consumption, and shortening offline fault detection and diagnosis downtime.
