在过去几年里。日益增长的空调需求导致了对一次能源资源的需求大幅增加。太阳能制冷技术是一种利用可再生太阳能，与传统空调设备相比具有重要节能效果的技术之一。本文介绍了太阳能制冷的不同技术装置及其运行方式、优点和局限性。本研究的目的是分析太阳能吸收制冷系统的技术和经济可行性，该系统设计用于两个不同的应用领域：工业制冷和空调。通过考虑一家肉类制造公司的制冷需求，以及位于意大利旅游城镇的一家酒店的供暖和制冷需求，研究了更换或整合现有工厂的可能性。在第一种情况下，该系统包括一台与太阳能平板集热器相连的吸收冷水机组，而第二种应用是关于一种称为热能-太阳能热电联产的混合热电联产装置；这一选项允许在有供暖和制冷形式的能源需求的场所有更大的操作灵活性，例如在酒店。这样，作者就可以比较基于现有用户的技术经济实验分析得出的不同结果，并评估其优缺点，以便为两个研究案例提出最佳解决方案。(C)2009爱思唯尔有限公司。保留所有权利。
In the last years. the growing demand for air conditioning has caused a significant increase in demand for primary energy resources. Solar-powered cooling is one of the technologies which allows to obtain, by using the renewable solar source, an important energy saving compared to traditional air conditioning plants. The paper describes different technical installations for solar cooling, their way of operation, advantages and limits. The objective of the present study has been to analyze the technical and economic feasibility of solar absorption cooling systems, designed for two different application fields: industrial refrigeration and air conditioning. The possibility to replace or integrate the existing plants is studied, by considering the refrigeration requirements of a company, which works in meat manufacturing, and the heating and cooling demands of a hotel located in a tourist town in Italy. In the first case, the system comprises an absorption chiller coupled to solar flat plate collectors, whereas the second application is about a hybrid trigeneration plant, known as thermo-solar trigeneration; this option allows having greater operational flexibility at sites with demand for energy in the form of heating as well as cooling, for example in a hotel. In this way the authors could compare different results obtained by a technical and economic experimental analysis based on existing users and evaluate the advantages and disadvantages in order to suggest the best solution for the two studied cases.
