Endbericht Solare Kühlung und Klimatisierung – IEA SHC Task 38, Phase II 6 2 Summary The overall goal of IEA SHC Task 38 „Solar Air Conditioning and Refrigeration“ is the development and testing of compact solar heating and cooling systems with low nominal capacity, custom-built high capacity systems for non-residential applications and the development of new thermally-driven cooling machine concepts and components for solar applications. Beyond the technological focal point, the goal of the collaborative research project is an efficient know-how transfer to the users of this technology and to the relevant industry in order to promote market implementation. IEA SHC Task 38 is based on the results of two previous IEA-SHC tasks, Task 26 Solar Combisystems and Task 25 Solar assisted air conditioning of buildings. Based on the results of these two tasks, concepts and systems for solar heating and cooling will be developed and tested: • Compact systems for solar heating and cooling in a capacity range of 2 – 20 kW. • Custom-built high capacity systems for non-residential applications • New concepts of thermally-driven cooling machines and components IEA SHC Task 38 is divided into 4 subtasks: Subtask A: Small and medium pre-engineered systems Subtask B: Large sized custom-made systems Subtask C: Modeling and fundamental analysis Subtask D: Market transfer activities The main activities within Task 38 of the partners participating in this project are in Subtask A, which is led by AEE INTEC. In this subtask, system concepts for small and medium compact systems have been developed, compared and tested in pilot applications. The goal was to come to system packages that contain a solar combisystem for domestic hot water and space heating and use the surplus solar energy in summer for cooling applications. Such systems should be offered as pre-engineered packages so that they can be designed and built by installers without the need of customized design studies. Practical operation experiences from demonstration systems are an important input for the development of pre-engineered solar heating and cooling systems. Exchange of experiences was achieved on a personal level by means of presentations and discussion at the expert meetings. In addition a common procedure for monitoring of demonstration plants as well as for the analysis of these data was defined. This makes monitoring data of different plants comparable. An Excel-Tool was developed where data of a whole operating year can be entered. Automatically the tool will then calculate a large number of key figures to compare. This Excel-Tool was used to analyze monitoring data of 11 small and medium scale plants (Subtask A) and 11 large custom-made plants (Subtask B) and to compare them with eachother. Three of the small and medium scale plants and three of the large plants were in Austria. AEE - Institut für Nachhaltige Technologien
Endbericht Solare Kühlung und Klimatisierung – IEA SHC Task 38, Phase II 7 The partners of this project were also involved in other activities of Task 38. This concerns mainly the following work packages Subtask B: Analysis of the solar heating and cooling system of the town hall / service center of the city of Gleisdorf Subtask C: New developments (parabolic trough and steam jet ejector chiller), hygienic heat rejection units, analysis of simulation tools Subtask D: Handbook for planners, co-authors for the completely new edition of the handbook of Task 25. IEA SHC Task 38 started with the kick-off meeting in October 2006, was prolonged and ended in December 2010. The results of the task are published in a series of technical reports. A part of these reports can already be downloaded from the IEA-SHC hompage www.iea-shc.org, some reports are only being completed during 2011 and can then also be downloaded from this homepage. The main part of the task results will be included in the new edition of the “Handbook for Planners” that will be available in bookshops by the end of 2011.
