基于环境空气综合温度的供热节能潜力分析

Analysis of Heating Energy Conservation Potential Based onIntegrated Temperature of Ambient Air

本文利用热负荷延续时间图分析了用环境空气综合温度替代室外空气温度进行供热运行调节时的节能量。分析结果表明,在保证室内舒适度不变的前提下,以环境空气综合温度替代室外空气温度用于供热系统运行调节,可降低系统的供热量。在太阳资源三类地区,节能率为2.6%~4.4%;在太阳资源一类和二类地区,节能率为8.8%~11.5%。在太阳能资源越丰富的地区,节能率越大,节能潜力也越高。

In the paper,heating load duration graph was used to analyze the energy saving when the integrated temperature of ambient air could replace outdoor air temperature for heating operation regulation.The results showed that systematic heat load could be reduced when integrated temperature of ambient air was adopted in the operation of heat supply system instead of outdoor air temperature under a fixed indoor comfort degree.In the first and second tier region of solar energy resources,the energy conservation potential was between 8.8%and 11.5%;while in the third tier region,it was 2.6%to 4.4%.
