A variation of the solar chimney concept is the solar attic. In a hot sunny climate the attic space is often blazingly hot in the summer. In a conventional building this presents a problem as it leads to the need for increased air conditioning. By integrating the attic space with a solar chimney, the hot air in the attic can be put to work.
A solar chimney (or thermal chimney) is a passive solar ventilation system composed of a hollow thermal mass connecting the interior and exterior of a building. As the chimney warms, the air inside is heated causing an updraft that pulls air through the building. These systems have been in use since Roman times and remain common in the Middle East.
A solar chimney is a chimney of outside black color. They were used in Roman antiquity as a ventilation system. The black surface makes the chimney heat with sunlight. The air inside gets warmer and moves up, pumping the air from the underground, that is at 15 °C (288 K) all the year.
The solar cyclone distiller [73] could extract atmospheric water by condensation in the updraft of the chimney. This solar cyclonic water distiller in the updraft above a solar collector pond could adapt the solar collector-chimney system for large-scale desalination of collected brine, brackish- or waste-water pooled in the collector base. [74]
If building air is blown through the heat exchanger for heat recovery ventilation, they are called earth tubes (or Canadian well, Provençal well, Solar chimney, also termed earth cooling tubes, earth warming tubes, earth-air heat exchangers (EAHE or EAHX), air-to-soil heat exchanger, earth channels, earth canals, earth-air tunnel systems ...
Solar chimney – solar chimney — often referred to as a thermal chimney — is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. Solar collector – Solar cooker – or solar oven, is a device which uses the energy of sunlight to heat food or drink to cook it or sterilize it.
