• Applications with a great changing energy demand like weekend break in industrial processes (e. g. industrial laundry).

• Useful temperature levels at low radiation and low ambient temperatures (space heating).

• Need of air with high temperature level e. g. bakerys, burning in of coatings.

• Avoidance of humidity problems in buildings and condensation occurences in sensitive electrical applications. Also through the regeneration of sorption materials at daytimes.

• Applications with lightweight, water critical, or optical flexible requirements.

• Drying of sorption materials with high temperature.

• Drying applications (e. g. wood, food etc.).

• Heating of industrial or high rise buildings with large collector fields.

• Solar cooling: open-cycle desiccant evaporative cooling (DEC).

• Solar domestic hot water and space heating with a fin heat exchanger.

3.2 System Components

• Collector

• Fan

• Solar controller with temperature sensors.

Optional

• Heat exchanger, air — fluid (fluids are for e. g. water, oil, steam, chemical products).

• Storage tank e. g. with water, pebble beds or sorption materials.

• Solar radiation sensor to check the system.

2. Conclusions

At the Kollektorfabrik the series production of the solar air collector has started.

A new collector for the requirements of applications with high solar fraction without the risks of a stagnation state is available.

For private usage the collector is suitable for space heating and domestic hot water preparation. Especially holiday residences can be dehumidified while not occupied in order to avoid moisture while there is no risk of stagnation problems. During occupation the system can additionally provide domestic hot water.

For commercial and industrial usage the collector fits best for drying applications, solar cooling and large scale heat demand.
