Many features have been developed over the past few years which, when used
singly or in combination, have the potential to significantly improve the
performance of active solar systems. It is the objective of Task 14 to analyze,
construct and monitor a number of different systems incorporating one or more of
these features. Five-year cost/performance improvement goals have been
established by the participants.
The projects fall into three general application areas: domestic hot water,
ventilation air and space heating, and large scale heating systems. Working
groups have been formed to facilitate interaction among participants with
The countries participating in the domestic hot water group have focused on
developing generic, cost-effective, "dream systems" which represent national
preferences as well as the collective wisdom of the group members as to the best
components and design.
The ventilation air and space heating group is studying an innovative technology
for heating ventilation air in industrial and commercial buildings. The
perforated solar absorber promises to be 35 - 40% more cost-effective than
conventional solar air collectors for low-temperature air heating applications.
The systems in the large scale heating group include a desalination project, an
agricultural process heating project, and a central solar heating plant.
The work of the dynamic system test procedure working group is now continuing
under Task 14. The aim is to establish better solar collector and DHW system
test procedures for standardization.
