散热器手动调节的节能效果测试与分析

对北京市某小区的分户计量供暖系统进行了测试,得到了散热器手动调节阀不同调节工况下的室温动态变化数据。以参考房间为基准,提出了能耗百分比及邻户传热百分比的概念,分析了散热器手动调节的节能效果。测试分析结果表明,长期关阀调节工况下节能率可达20%左右,按作息规律间歇调节时节能率约为6%;在系统总体供暖充足的前提下,设置散热器温控阀可利用太阳辐射等自由热达到较好的节能效果。

Test and analysis on energy saving effects of radiator manual adjustment

Through the measurement of a household metering heating system in Beijing,gains dynamic data of room temperature under various operating conditions of radiator manual control valves.Based on the reference room,gives the concept of energy consumption percentage and heat transfer percentage between adjacent rooms and analyses the energy saving effect of radiator manual adjustment.The testing and analysing results indicate that the energy saving ratio can reach up to about 20% under the condition of valves closed for a long time and reach up to about 6% by adjusting valves intermittently according to living schedules,and that installing radiator thermostatic valves in the system heated adequately can obtain good energy saving effects by using the free heat such as the solar radiation.
