一、改善建筑物的保温性能为了降低暖通空调系统的耗能量、初次投资和经常性的运行费用,改善建筑物的保温性能是一个重要环节。很多国家都从能源经济学的观点出发,对建筑物的保温性能作了新的规定,以限制建筑物的耗能量。归纳起来,大致有以下三种方法。 1.度日法(Method of degree days):是以度日数为依据,根据不同性质的建筑,给定其外围结构的平均传热系数,如附图所示。 First, improve the insulation performance of the building In order to reduce the energy consumption of the HVAC system, the initial investment and the regular operating costs, improving the insulation performance of the building is an important part. Many countries have made new regulations on the insulation performance of buildings from the viewpoint of energy economics to limit the energy consumption of buildings. To sum up, there are roughly the following three methods. 1. Method of degree days: Based on the degree days, according to the different nature of the building, given the average heat transfer coefficient of its peripheral structure, as shown in the figure.
