夏热冬冷地区典型城市的采暖模式能耗分析

Energy analysis of the typical city heating mode in hot summer and cold winter zone

为了解决能源的紧缺和人们对舒适性的要求之间的矛盾,选择合理的采暖模式势在必行。作者针对夏热冬冷地区进行为期一个月的调研统计,确定出该地区住宅建筑的常用采暖模式,并对其进行能耗模拟。首先利用Dest-h软件计算采暖季的逐时负荷;然后根据厂家提供的设备样本,以部分负荷率下的机组效率曲线为依据,建立能耗模型,计算不同采暖模式的采暖能耗。结果表明水源热泵系统最节能,是一种解决采暖系统能耗高问题的有效方法,适合于夏热冬冷地区能源紧缺的城市。

In order to solve the contradiction between people＇s demands on comfort and energy shortage, it is imperative of the heating mode being choised reasonably. The author spent as long as one month conducting investigation in hot summer and cold winter region, to ensure the main heating ways of residential building in the region, and carried on the energy simulation. Firstly, Dest-h software is used to calculate the heating load in this paper, According to the samples of performance parameters provided by equipment manufacturers, especially the efficiency curve under partial load rate,the author builded the calculation formula for energy consumption of different heating mode. It is concluded that water source heat pump system is the most energy saving, and it is one of the effective way to solve the high energy consumption solution of HVAC system. It is suitable for the city of energy shortage in hot summer and cold winter region.
