Basist D. Improvement of thermohydrodynamic sustainability of automated systems of water heating

Actuality and orientation of the thesis are aimed at the increase of hydraulic and thermal stability, power and general efficiency, both traditional and modern CASS of the hot-water heating of multistory building. The conceptual approach is set to the analytical determination of gravitational pressures in the heating systems of multistory building with the intermediate arrangement of heat source. On the basis of the above-stated facts the new technical decisions of the systems and chimneys that differ in a patent novelty. The technical decisions of the heating systems "with middle interconnection" of mains and risers of special construction got further development, which differ in increased hydraulic stability, power and technically-economical efficiency, and also the new dependence as irrational equalization set interplay between thermal and hydraulic stability. Results of the pilot study of the system with intermediate heat source location confirmed a reliability of received analytical dependencies both for reduction their hydraulic resistance with risers of the offered system and for minimization the gravitational pressure with decreasing of vertical thermohydrodynamic systems. Application of the systems of the hot-water heating with the intermediate arrangement of the source of heat taking into account the set factors of decline of capital and operating costs predetermines their technically economical efficiency of introduction into the industries of construction of multistory buildings. It is necessary to adjust the level of arrangement of the technical floor in the multistory buildings according to the dependences which have been obtained
