某高校宿舍楼供暖节能模拟分析

Simulation analysis of heating and energy saving in a college dormitory building

以呼和浩特市某高校宿舍楼为研究对象,对整个供暖季燃气消耗量进行实测。利用Energy Plus模拟分时段低温供暖、室内热环境及天然气消耗量,在满足热需求的条件下,达到减少天然气消耗量的目的。结果显示,分时段低温供暖方式均满足室内热需求,在初寒期、严寒期、末寒期相比实际燃气消耗量分别节省13.9%、6.9%、8.7%,总共消耗量约95 271.3 m^(3),比实际节省9.3%。

Taking a dormitory building of a university in Hohhot as the research object, the gas consumption in the whole heating season was measured. Energy Plus is used to simulate indoor thermal environment and natural gas consumption under low temperature heating in different periods, so as to reduce natural gas consumption under the condition of meeting heat demand. The results show that the above low-temperature heating modes in different periods all meet the indoor heat demand, and the actual gas consumption is saved by 13.9%, 6.9% and 8.7% respectively in the initial cold period, severe cold period and final cold period, and the total consumption is about 95 271.3 m^(3), which is 9.3% less than the actual consumption.
