摘要
热回收技术作为一种空调节能手段,在建筑节能领域得到越来越多的研究应用,显热回收和全热回收这两种方式则成为了人们所选择的对象。为了比较排风热回收技术显热回收与全热回收这两种的节能性与经济性,通过对北京地区某图书馆的工程案例,采用排风热回收技术分别进行显热与全热回收的经济性计算分析。最终发现在北京地区,显热回收方案下的投资回收期在2.55年,全热回收方案只有1.75年,时间更短;而12年后的经济收益中,全热回收方案比显热回收方案多出83.23万元。
As an energy-saving means of air conditioning, heat recovery technology such as sensible heat recovery and total heat recovery has been more and more applied in the field of building energy conservation.In order to compare the energy efficiency and economy between sensible heat recovery and total heat recovery, through an engineering case of a library in Beijing, the economic analysis of sensible heat recovery and total heat recovery was carried out by using exhaust heat recovery technology. Finally, it is found that in Beijing, the payback period under the sensible heat recovery scheme is 2.55 years, and the total heat recovery scheme is only 1.75 years, which is shorter. In the economic benefits after 12 years, the total heat recovery scheme is 832,300 yuan more than the sensible heat recovery scheme.
