Objectives

The main objective of Task 25 was to improve the conditions for the market entry of solar assisted cooling systems in order to promote a reduction of primary energy consumption and electricity peak loads due to cooling.

Therefore the project aims were:

• The definition of performance criteria of solar assisted cooling systems considering both energy-relevant as well as economic performance
• The identification and further development of promising solar assisted cooling technologies
• An optimized integration of solar assisted cooling systems into the building and the HVAC-system focusing on an optimized primary energy saving - cost performance
• The creation of design tools and design concepts for architects, planners and civil engineers

The main results of the task work are:

• Handbook for solar assisted air-conditioning (component description, system description, operation and control issues, design guidelines)
• Book of solar assisted air-conditioning demonstration projects
• Computer-based design tool
