【 摘 要 】

The article determines application potential of solar energy in conditions of sharply continental climate. It presents an energy-efficient solar energy recovery scheme in district heating systems, allowing to reduce capital costs and maintenance charges and to increase degree of substitution of conventional sources of heat. Versatility of systems using this method results in its multi-zone application: From a cottage-type house to heating of industrial premises and green house complexes. The main principle of the suggested method is in connection of a solar collector via heated medium to an air conduit, which is connected with heated space and antifreeze, circulating in-line: Reservoir-accumulator-solar collector. A method of heat transfer enhancement using dimple-type intensifiers is suggested. The article determines enhancement efficiency via calculation of daily heat-absorption of a flat air collector with and without dimple intensifiers, as well as economic effect from introducing of the suggested method. According to calculations, the adoption of the suggested heating system and heat transfer enhancement on the surface of the collector connecting to it, may give a perceptible economic effect.
