||In recent years, a new type of large forced circulation solar hot water system constructed by connecting a series of small domestic natural circulation systems appeared in the market. In this study, we compared the performance of this type system with/without a large storage tank with the formal forced circulation hot water system in different solar collector arrangement, (series, parallel), and load supplying time T_1 (18:00~24:00), T_2(12:00~24:00), T_3(00:00~24:00) for six major cities of Taiwan via a computer simulation to calculate monthly and annual solar fractions.|
The results indicate that:
1.the annual performance of the new type system with no large storage is better than the system with one, and also better than the formal forced circulation system. However, in winter, the performance of the formal forced circulation system is the best.
2.the load time T_2 provides the best solar fraction.
3.the system with solar collectors connected in parallel performs slightly better than in serial.
