在太阳能设施增投资一定的条件下,本文以被动太阳房年供暖所需辅助能耗为目标函数,利用黄金分割法多维寻优找到使年辅助能耗最小时的围护结构保温程度、南向直射窗面积、南向集热墙面积这三个设计要素之间配比。 这些最优配比关系和房间尺寸、材料价格、气象条件和设计室温等因素有关。本文编制了OPTIC程序,在输入上述诸参数后即可得出在一定增投资下的最优三要素配比,并给出了一张计算图表示例。最后还举例说明优化与非优化方案在经济效益上的差别。
Under the condition that the investment in solar energy facilities is increased, this paper uses the auxiliary energy required for annual heating of the passive solar house as the objective function, and uses the golden section method to find the optimum degree of heat preservation of the building envelope when the annual auxiliary energy consumption is minimized. The ratio of the three design elements of the direct window area and the southward collector wall area. These optimal ratio relationships are related to room size, material prices, weather conditions and design room temperature. In this paper, the OPTIC program is compiled. After inputting the above parameters, the optimal three-element ratio under a certain increase of investment can be obtained, and an example of a calculation chart is given. Finally, it also illustrates the difference in economic efficiency between optimized and non-optimized solutions.
