F-Chart 設計法에 의한 太陽熱住宅의 暖房性能에 關한 硏究

This paper presents a method for estimating the useful output of solar heating systems. Heating load calculations, climatic data and various conditions are used in this procedure to estimate the fraction of the monthly heating load supplied by solar energy for a particular system. The design procedure presented in this paper referred to the f - chart method. The results of this study are as follows; 1) The collected energy is not rised lineary to collector area. 2) If the heating area has equivalent solar collector area, the solar energy utilization for space heating is over 90%. 3) Transmittance - absorptance product for radiation at normal incidence, (τα)/( τα)n, during most of the heating season is 0.92 for a two - cover collector. 4) Orientation of the collector has little effect on the annual performance of heating system within the 15°.
