Heating of a large industrial building with solar air-collectors in comparison with a conventionally heated building
The suitability of solar air-collectors for the saving of heating energy in hot-air heated halls is to be demonstrated. With regard to energy consumption, one hall with solar air-collectors is compared to a reference hall without solar technique under the same conditions of time, place and use over three heating periods. The air-collectors used are added on the air-side of the conventional air-heaters with oil-fuelled back-up heating. This leads to a high solar use with a starting point just above room temperature, with uncomplicated technique and relatively low cost of investment. Reasonable investment expenditure provides an energy saving of 50%; this is sufficient to compete with other building projects. Tenders can already be invited for this technique of installation and firms involved with ventilation and air-conditioning techniques are able to install it. In the meantime, the air-collector used has been further developed to a higher degree of effectiveness. With regard to low investment costs, the planning engineer's work is of decisive importance.
