Nakonechniy V. Energy-and resource-saving technologies in heating and ventilation of residential buildings.

The thesis is devoted to the improvement of heating and ventilation systems in their periodic work on the basis of the combined system panel radiant and convective heating to maintain the internal environment parameters premises. In processes used to study the transfer and distribution of thermal energy in the room heating devices with various quantitative coolant and control the ventilation rate decreases, which showed that the condensation of moisture from the indoor air on the inner surface of the window construction, leading to reduced heat resistance and appearance of heat transfer bridges, thus causing, in the indoor heat losses increase to 30%. Theoretical and experimental study of low-temperature water heating systems showed that when ventilating with outdoor air through natural ventilation does not provide the necessary rules for the internal temperature of the air, and there is a significant non-uniformity of temperature distribution on the height of the room. We propose a combined water heating system with the installation of low-temperature radiant panels over the window opening and the other heating appliances in the place of greatest heat loss, characterized in that it is condensing on the surface of the window opening is achieved by heating them above the dew point temperature of the radiating plate, and the second part of the system compensates for heat loss. Experimental work confirmed the proposed combination of low temperature heating system, with the resulting savings of thermal energy (relative to the radiator system) to 20% during the heating period.
