Six rolls circling through two airstreams (hot/cold)
Solar Chimney + Zeolite Airdrying Hot air moves upwards and passes rotating rolls with the dessicant Zeolite. The dessicant is now dried and suitable for absorbing moisture from the incoming air. Fresh air gets dehumified by the dessicant and directly humified afterwards. This causes a chill effect and downwards air movement in the cold air channel.

The solar chimneys produce under pressure. Fresh (cooled) air comes in through a zeolite/evaporative system, filtering/evaporative plantboxes and opened windows. The ceiling and vertical airchannels are cooled by absorbtion chillers (Invensor LTC30). These coolers are powered by solar heat collectors (blackboxes/vacuumtubes)
The solar chimneys produce under pressure. Fresh air comes in through an heat exchanger and filtering plantboxes. The incoming air is then prewarmed in channels next to the low temperature floor heating. This heating energy is obtained by solar heat collectors (blackboxes/vacuumtubes) - which can be stored in a saltsolution - and a conventional (natural) gas heating installation for extremely cold days.
