Zusammenfassung: | Energy systems for consumers? supply with sanitary hot water (SHW) can be
considered as a separate category of the system with many similar functions,
performances and integral elements. This similarity of energy systems for SHW
supply and the way in which they are used enable systemic planning, proposing
and undertaking measures for improvements and advancements. This is possible
not only by the reconstruction and modernization of existing technological
solutions but also by their replacement with new, modern and more efficient
solutions. The basic idea and the aim of this paper is the development of a
concept for integrated and upgraded system of SHW supply for different types
of buildings from residential to more complex buildings intended for
different purposes. The analysis is based on the application of a systemic
approach adapted to the conditions in urban communities and includes only
modern but commercial technologies. This paper presents the results of a net
energy analysis of integrated central and solar hot water supply system and
compares it with the conventional sanitary hot water system in the City of
Novi Sad, Serbia. The proposed methodology is demonstrated through a
simulation example. It is shown that 23% reduction in the total system?s
costs can be achieved as compared to the existing solution. Also, the
methodology is applied to a residential block as a unit and obtained results
indicate that investments in the development and construction of integrated
systems are justified.
