Pukhovyi I. Heat and cold supply of building with the assistance of solar and environment energy (in a complex with traditional energy sources and without them)

The heat supply system on the basis of traditional and renewable sources of energy with different temperature levels is proposed and investigated theoretically and experimentally. Renewable sources of energy with different temperature levels are used for directly heating of air in the buffer space area between the wall and transparent building protection of the passive solar heat supply system (PS) and for other types of building constructions. Mathematical models for determination of temperatures and efficiency of mentioned systems are worked out and patented under the name „System PKHV”. Integrated work modes of „System PKHV” with heat pump are investigated theoretically. Comparison of work modes of mentioned systems is executed. The prospects of use of natural and origin water with temperature 0-30 0С, of water crystallization heat, of subsoil waters heat for heat supply, ventilation, air-preheating on inlet of heat pump and air-conditioning are proved. Passive solar heat supply systems and solar collector for generation of steam for technological purposes are experimentally investigated. Numerical characters of insolation with the account of cloudiness and orientation of vertical PS and solar collectors for different regions of Ukraine are determined.
