随着电子计算技术在应用科学和工程技术中的广泛应用,近十多年来,国外已先后发表过多种用不稳定传热法计算建筑物空调负荷的方法:蓄热负荷系数法、反应系数法、互传递函数法、冷负荷系数法及计算分项负荷的时间平均法、吸热修正系数法、加权系数法(又称重量系数法)和公比法等等。从对空调工程以及一些高层宾馆的实测结果发现,国内计算的建筑物冷热负荷比实际需要量大。普遍感到,得出我国统一的、比较先进的建筑物空调负荷计算方法已成为一个急待解决的问题。前一阶段,我们曾对空调设计用冷负荷的几种新的计算方法,按透过窗玻璃相同的太阳辐射热,分别计算了这一项负荷,并作了比较。为便于说明问题,我们先将进行比较的几种方法:冷负荷系数法,时间平均法、互传递函数法、蓄热负荷系数法、加权(重量)系数法、吸热修正系数法及公比
With the wide application of electronic computing technology in applied sciences and engineering technology, in the past decade or so, a number of methods have been published abroad to calculate the air conditioning load of buildings using the unstable heat transfer method: heat storage load coefficient method, response Coefficient method, mutual transfer function method, cold load coefficient method and time-average method for calculating partial load, endothermic correction coefficient method, weighted coefficient method (also called weight coefficient method) and common ratio method, and the like. From the results of air conditioning projects and some high-level hotels, it has been found that the calculated cooling and heating loads in China are greater than the actual requirements. It is generally felt that it has become an urgent problem to draw a conclusion that our country’s unified and relatively advanced calculation method for building air-conditioning load has become an urgent issue. In the previous stage, we have calculated the load for the new calculation method of the cooling load for air-conditioning design by comparing the same solar radiant heat through the window glass and made a comparison. To illustrate the problem, we first compare several methods: cold load coefficient method, time average method, mutual transfer function method, heat storage load coefficient method, weighted (weight) coefficient method, endothermic correction coefficient method and common ratio
