本文阐述了求解直流式太阳能热水系统热性能的数学模型,利用电子计算机求得了该系统热性能的理论值,并与实验值进行了比较。论证了用连续流动系统的数学模型来求解间断流动系统(放水)的热性能是可行的。提出了此种系统更为简便的设计计算方法,并指出了改进系统装置、提高系统热性能的某些途径。
In this paper, a mathematical model for solving the thermal performance of a direct-flow solar hot water system is described. The theoretical thermal values of the system are obtained using an electronic computer, and compared with the experimental values. It is demonstrated that it is feasible to use the mathematical model of the continuous flow system to solve the thermal performance of the intermittent flow system (discharge). A more simple design calculation method for such a system is proposed, and some ways to improve the system device and improve the thermal performance of the system are pointed out.
