【摘要】 在主动式太阳能供暖中集热器面积的选择是一个十分重要的问题。为了更好地利用太阳能供暖,本文仅从经济评价的角度,建立太阳能集热器和辅助热源(电加热)联合供暖年计算费用的数学模型,寻求使年计算费用最小的集热器面积,并举出工程实例加以说明。更多还原

【Abstract】 It′s of great importance to choose appropriate collector′s area in active solar energy heating.In order to make good use of solar energy,this article elaborated the digital models in annual calculating expense by the combination of solar energy collector with auxiliary power(electricity heating),and how to minimize annual calculated expense,together with several actual engineering instances to demonstrate.更多还原
