摘要
本文首先根据小型别墅的热水供应和采暖需要,建立了小型别墅季节性蓄热太阳能供热系统流程,进而根据某一特定城市的气象数据,进行全年逐时的计算机模拟。在此基础上,研究了全年热量平衡,各月太阳能供热量,不同蓄热容量对全年太阳能保证率、集热器集热效率、水箱温度的影响。并由此得出结论:蓄热容积是集热面积的3倍左右时,集热器年平均集热效率较高,且在进入冬季时可利用水温差较大;且采用大蓄热容积配合分隔水箱的方式,可以有效提高太阳能在冬季的利用。
By modeling the flow of solar energy with heating storage to meet hot water supply and heating load for residential house, the system performance is simulated on the basis of given weather date hour by hour. Influence on the solar assurance rate, solar collector thermal efficiency and water temperature in the tank is studied according to the heating balance of whole year, quantity of the solar heating and different heating storage volumes. When the storage tank is triple of the collector areas, the yearly average efficiency is higher and the available difference of temperature is bigger. Using large volume storage tank divided into several parts can efficiently elevate solar energy＇s utilization in winter.
