太阳能应用于制冷领域，具有良好的节能性和环保性，符合可持续发展战略的技术要求。因此引起国内外很多研究人员的重视。太阳能吸收式制冷作为太阳能制冷技术中的一种，近年来发展很快。但由于太阳能用于制冷是一种新型的制冷技术，对于它整体系统的构成以及系统的工作原理没有给出明确的说明，在实际应用时会存在一定的盲目现象。因此，针对太阳能吸收式制冷装置集热系统与制冷机的有效配用问题开展一些深入的探讨，既有理论价值，又有重要的工程实用价值。 本文针对太阳能吸收式制冷系统的特点，对它的构成和原理作了简要介绍，同时分析出适合太阳能吸收式制冷系统的吸收式制冷机组。以南京地区某一住宅楼为例，利用DeST能耗模拟软件，对该住宅楼的冷负荷和太阳辐射强度进行动态模拟，得出在该地区气候条件下，住宅楼冷负荷和太阳辐射强度的逐时变化规律。并利用图表对其变化规律做出分析。 利用Origin7.5数据分析软件，对得出的冷负荷和太阳辐射强度进行曲线拟合，得出住宅楼总冷负荷和太阳能总辐射量。根据住宅楼的冷负荷需求，选出溴化锂吸收式制冷机，并根据制冷机的热源温度要求，利用提出的集热器效率公式，分析当集热工质进口温度确定后，不同集热器效率的变化规律，选出本文系统所用的集热器及其效率值。利用这些数值计算出为了满足该住宅楼整个空调季的需求所需要安装的集热器面积。最后在集热器有效集热范围内，确定出集热器在满足吸收式制冷机热源温度的同时所能提供的热水流量，以满足所选用的溴化锂吸收式制冷机的热源要求。 本文的研究不仅有节能方面的技术意义，更有实际的工程指导意义。该结论对太阳能吸收式制冷系统的设计具有重要的参考价值。

It has a good energy saving and environmental protection that solar energy used in refrigeration areas, and in line with technical requirements of sustainable development strategies. So many researchers at home and abroad pay a lot of attention on it. Solar energy absorption refrigeration is a kind of refrigeration technology in solar power ,which has developed rapidly in recent years. However, because of solar power for refrigeration is a new type of refrigeration technology, and it does not give specific description for its components of the whole system as well as the working principle, and it has been blind to be used in the practical application. Therefore, carrying out deeply some problems of the relationship of the solar collector with absorption refrigeration system, which can bring both theoretical and important works of practical value. In this paper gives a brief introduction for its composition and principle of solar absorption refrigeration system, at the same time analyzes the absorption refrigeration units which are fit for solar absorption refrigeration system. Take a residential building in Nanjing as an example, using energy simulation software DeST to give dynamic simulation for the cooling load of residential buildings and solar radiation intensity, and elicit the laws of hourly changing for the cooling load of residential buildings and solar radiation intensity in the area of climate conditions, meanwhile, use charts to make its analysis of changes. Using data analysis software Origin7.5 to give curve fitting for the cooling load and solar radiation intensity and educe the total data of them. Choose Lithium Bromide Absorption Chiller in accordance with the cooling load demand of residential buildings. At the same time, using the formula of the several kinds of solar energy collector efficiency to analyze its changing caused by its determined working fluid inlet temperature which determined by the requirements refrigerator temperature heat source, and select the data used in the collector in this paper. Using these data to calculate the collector area installed in order to meet the entire air-conditioning demand of the residential buildings. Finally at the scope of effective solar collector, determine hot water provided by it in the condition of meeting the heat source temperature of absorption refrigeration in order to meet the needs of the lithium bromide absorption chiller heat source requirements. This study not only have energy-saving technical meaning, but a more significant practical guiding for the project. The conclusion is an important reference value for the design of solar absorption refrigeration system.
