Solar heating in mountain refuges

At the beginning of winter, solar air reached the mountain huts of Ventosa and Calvell, located in the Aigüestortes National Park in the Spanish Pyrenees, at 2.220 meters above sea-level. The Twinsolar 8.5 – an air collector of 8,5 m², completely self-sustaining as operated by a photovoltaic module – heats the cabins, creating a cosy ambiance for alpinists and other visitors.

Energy efficiency in historic buildings

Modern SolarAir technology for the energy garden at Trebsen Castle

Rising energy costs are making the management and thus the preservation of historic buildings more and more difficult. Therefore, the German environmental foundation DBU promotes a project at the Trebsen Castle near Leipzig , in order to heat predominantly by solar insulation a vaulted cellar of the 16th century.

Aurinkolämpö talteen kuumailma-aurinkokeräimillä

Suomessa ainutlaatuiset kuumailma-aurinkokeräimet soveltuvat mökkien ja omakotitalojen lisäksi vaikkapa urheiluhallien lämmitykseen ja ilmastointiin.

Vantaalainen Aurinkoinsinöörit Oy ryhtyy tuomaan maahan Saksassa kehitettyjä TwinSolar^®-, TopSolar^®- ja JumboSolar^®-aurinkokeräimiä. Kuumailma-aurinkokeräimet ovat Suomessa ainutlaatuisia, sillä täkäläisillä markkinoilla auringonlämmön hyödyntämiseen on tarjolla lähinnä putkikeräimiä.

SOLAR AIR-PLANT AT 3.600M ALTITUDE INSTALLED IN TIBET

 AMBERG/LHASA – Pleasantly warm class rooms – this is what the about 200 students of a vocational school in Danxiong wish for themselves. The place is located in Tibet, and the prospective carpet weavers there may look forward to warm hands. Grammer Solar has sent SolarAir-collectors there. For the professional installation Gerhard Kreißel travelled from Upper Palatinate in Germany to Far East - and gained some Tibetan experiences.
