摘　　要：以西安市某小区的供热系统为例,分析了目前供热系统存在的问题,并针对系统存在的问题提出了相应的改造方案以及系统节能改造后的节能分析。系统通过分时分区供热、加装自力式流量控制阀、采用变频泵变频调节、混水技术以及自动控制系统的改造后,供热系统不仅实现了节能运行,并且提高了供热品质,还为日后的供热计量收费奠定了基础。Base on a district heating system in Xi＇an, this paper analyzes the problems in the heating system, then presents some measures to saving those problems. In the end of this paper, the author analysis the energy savings. By taking the measures of time and zone control, install operated flow control values, frequency adjustment, mixed supply and return water temperature, and automatic control system. This heating system not only achieves the energy-saving operation, and improves the heating quality, but also good for heating metering charges in the future.
