Survey of Solar Assisted Cooling

The objective of Subtask A was to provide a picture of the state of the art of solar assisted cooling. This included evaluating completed solar cooling research programs and evaluating projects realized in the past.

Subtask Lead Country: Mexico

Desiccant rotor for open cooling cycle


Design Tools and Simulation Programs

The objective of Subtask B was to develop design tools and detailed simulation tools for system layout, system optimisation and development of advanced control strategies for solar assisted cooling systems. The main result was an easy-to-handle design tool for solar assisted cooling systems dedicated to architects, building engineers and planners.

Subtask Lead Country: Germany


Technology, Market Aspects and Environmental Benefits

The objectives of Subtask C were to provide an overview of the market availability of equipment suitable for solar assisted air-conditioning and to support the development and market introduction of new and advanced systems. Design guidelines for solar assisted air-conditioning systems were developed. Main results were summarized in a handbook for planners.

Subtask Lead Country : Netherlands (until 2002), Austria (2002-2004)


Solar Assisted Cooling Demonstration Projects

Eleven demonstration projects were carried out and evaluated in the framework of Task 25. The objectives were to gain practical experience with solar assisted cooling in real projects and to make data real performance data available. Also the suitability of the design and control concepts were studied and reliable results about the overall performance of solar assisted air-conditioning have been achieved.
