摘要

建立了直接膨胀式太阳能热泵系统的实验装置。在该装置中,光板太阳能集热器也用作热泵蒸发器。在5月份晴朗的天气下,笔者对热泵系统进行了实验研究。实验结果表明,在整个实验过程中,系统的COP和集热效率分别达到2.50 ~ 3.35%和50.0% ~ 75.2%。同时,对太阳辐照度、冷凝温度等参数对系统COP和集热效率的影响进行了分析和讨论,为系统的应用提供一定的参考。

Theoretical and experimental research on the thermal energy management system of direct expansion solar heating
The author has established the experimental device of the direct expansion solar heat pump system. In this device, the bare plate solar collector is also used as a heat pump evaporator. Under the sunny weather in May, the author conducted an experimental study on the heat pump system. The experimental results show that during the whole experiment, the COP, and the heat collection efficiency of the system reached 2.50-3.35 and 50.0-75.2%, respectively. At the same time, the influence of solar irradiance, condensation temperature and other parameters on the COP and heat collection efficiency of the system is analyzed and discussed, so as to provide some reference for the application of the system.

期刊介绍: The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
