Due to the reduction of fossil resources, the replacement of renewable energy sources such as solar energy has become mandatory. Solar energy does not contain pollution and widely available in all parts of the world, especially in warm regions. Our country (IRAN) is geographically located in a hot and dry region, and with more than 280 sunny days per year, one of the nonpower applications of solar energy is heating space and water consumption of the building using solar thermal energy. Solar water heaters can be used to heat the water used in buildings, which is the main purpose of this study. Water heating consumes an average of 20% to 30% of the total energy consumption in the residential building. Therefore, using solar water heaters annually can provide 70% of the energy needed for water heating. The system designed in this research is able to provide 75% of the hot water consumption needs. If an auxiliary heat source is used next to this system, all hot water needs of the building can be met throughout the year. In this case, as much as 237.3 kWh, energy will be saved from fossil energy sources.

住宅建筑用太阳能热水器系统的热和环境分析

由于化石资源的减少,替代太阳能等可再生能源已成为强制性要求。太阳能不含污染,可在世界各地广泛使用,尤其是在温暖地区。我国(伊朗)地处炎热干燥地区,每年有超过 280 天的晴天,太阳能的非电力应用之一是利用太阳能热能加热建筑物的空间和用水量。太阳能热水器可用于加热建筑物用水,这是本研究的主要目的。水加热平均消耗住宅建筑总能耗的20%至30%。因此,每年使用太阳能热水器可以提供热水所需能量的70%。本研究设计的系统能够提供 75% 的热水消耗需求。如果在该系统旁边使用辅助热源,则可以满足建筑物全年的所有热水需求。在这种情况下,多达 237.3 千瓦时的能源将从化石能源中节省下来。
