摘要
现行规范给出的太阳能采暖保证率是基于连续稳定采暖,未考虑到被动得热引起的过热以及非连续采暖引起的无效用热等问题。因此不适合于间歇运行的太阳能采暖。据此提出兼顾被动有效得热和主动系统非连续供热的太阳能采暖有效保证率,并给出计算方法。通过模拟分析,得到不同地区太阳能有效保证率的取值范围。相比于传统的太阳能保证率,在不同建筑热需求下,太阳能采暖有效保证率均有不同程度的提升,可实现有限太阳能资源最大化利用。
The traditional solar heating fraction provided by the current specification is based on the continuous and stable solar heating,without considering the issues of overheating caused by passive heating and invalid heating caused by discontinuous heating. Therefore,it is not suitable for solar heating with intermittent operation. According to the above,the effective solar fraction has been put forward,which is combined the passive effective heating and noncontinuous heating of active solar heating system. And then the discussion and calculation method are conducted. Based on different solar resource partitioning,different ranges of effective solar fraction are obtained by simulating and analysis heat consumption for different regions. Compared to the traditional solar heating fraction,the effective solar fraction all have different degrees of increasing under different heating requirements. It realizes the limited resources to maximize the use of solar energy.
