Abstract Assessing the performance of solar heating and cooling systems, especially cooling systems using solar thermal or photovoltaic driving energy, in a common comparable format, is complicated by the numerous, alternative energy sources and design possibilities. A generalized technical and economic assessment methodology was developed and tested in the course of IEA SHC Task 53. This paper is summarizing the key facts for the assessment and showing the evaluation on the basis of two simulated cases including sensitivity analysis of main boundary conditions. One case is comparing an air/water heat pump with photovoltaic and solar thermal support for a small multifamily house located in Madrid. The second case is comparing a solar thermal driven absorption chiller with a photovoltaic supported heat pump system for a hotel with dominant domestic hot water demand in Innsbruck. The sensitivity analysis shows that photovoltaic and solar thermal systems are cutting across with the same trends. Lower costs have to be derived first, followed by the efficiency of the system. Cost competitiveness is achievable for both technologies with appropriate system design and control strategies.

太阳能加热和冷却的技术和经济评估——IEA SHC 任务 53 的方法和示例

摘要 评估太阳能加热和冷却系统的性能，特别是使用太阳能热或光伏驱动能源的冷却系统，以一种常见的可比形式，由于众多的替代能源和设计可能性而变得复杂。在 IEA SHC 任务 53 的过程中开发和测试了一种通用的技术和经济评估方法。本文总结了评估的关键事实，并展示了基于两个模拟案例的评估，包括主要边界条件的敏感性分析。一个案例是比较位于马德里的小型多户住宅的空气/水热泵与光伏和太阳能热支持。第二个案例是将太阳能热驱动吸收式制冷机与光伏支持的热泵系统进行比较，以供因斯布鲁克一家生活热水需求占主导地位的酒店使用。敏感性分析表明，光伏和太阳能热系统正以相同的趋势跨越。必须首先推导出较低的成本，其次是系统的效率。通过适当的系统设计和控制策略，这两种技术都可以实现成本竞争力。
