The Study of Buildings' Thermal Mode with the Development of Actions for Power Efficiency Increase (on the Example of "Southwest State University")

Purpose of research. The purpose of the study is to carry out an applied research of buildings' thermal mode of Southwest state university on the basis of energy audit results and development of scientific and technical actions of thermal sanitation including search of expedient options of enclosing structures' warming and increase of heat supply system by thermal energy accumulation.

Methods. Heat power indicators of research objects and their comparison with standards were defined on the basis of energy audit results. It was done for the research objective achievement. Possible options of bringing thermal resistance of enclosing structures to required values were analysed taking into account minimization of capital expenditure. Inclusion of warmth accumulators on transition phase in the system of heat consumption is offered. It is used for removal of heat superfluous at night from heating system and its rational use for economy consumption of thermal energy. Saved thermal energy is supposed to be used for hot water supply (HWS) in the afternoon. Integration of thermal accumulators allows to smooth unevenness of HWS loadings for decentralized heat supply system. Shutdown of the main source (heat generator) on usage time of accumulated warmth gives positive ecological effect, i.e. provides reduction of greenhouse gases emissions. Ways in efficiency increase of warmth faze changing accumulator of housing type is offered to use.

Results. Development of technical actions for ensuring power efficiency and increase in consumer's quality of research objects is a result of the carried-out research.

Conclusion. Implementation of developed actions for thermal protection and the use of energy efficient engineering actions allows to achieve the following results: to increase consumer quality of buildings, to bring parameters of an internal microclimate to standards; to prolong service life of enclosing structures considerably, to provide consumption economy of energy resources on heat supply due to decrease in transmission and filtration heat losses and rational heat expenses with the use of thermal storage devices; to reduce the volume of harmful emissions of combustion products due to shutdown of heat source by usage time of accumulated warmth.
