相变太阳热水系统中换热器合理设计的研究

THE STUDY OF RATIONALIZED DESIGN OF THE HEAT EXCHANGER IN THE PHASE-CHANGE SOLAR WATER HEATING SYSTEM

本文对带换热器的相变太阳热水系统进行了热性能分析,提出了数学模型,并用该模型研究了换热器对热水系统性能的影响。试验表明,带换热器的相变太阳热水系统的技术经济性能明显优于其它型式太阳热水系统。

A mathematical analysis and model of the thermodynamical performance of the phase-change solar water heating system with heat exchanger has been presented in this paper.The influence of the heat exchanger on the performance of the water heating system is also studied based on this model.The test results indicate that the economic benefit of the phase-change solar water heating system with heat exchanger is obviously better than other types of solar water heating systems.
