Technological sciences, energetics and power engineering (06T).

The dissertation investigates the issues of efficient energy use in building engineering systems possibilities by applying processes integration. Indoor climate formation systems are indicated as signally energy use building engineering systems. Traditional methods for evaluation of heat transfer in heat exchangers tender limited solutions for efficiency use of energy in them.

The main object of dissertation is to evaluate processes integration method application possibilities for determination and improving of public buildings engineering systems. The dissertation also focuses on combine the possibilities of processes integration in building engineering systems with minimizing exergy streams in the systems.

The paper approaches a few major tasks: determination of problematic building engineering systems, equipment and processes by viewpoint of energy efficiency, analysis of ventilation design solutions, creation of algorithm for exergy input minimizing in building engineering systems processes by combination of thermodynamical and Pinch analysis methods.

The dissertation consists of four parts including Introduction, 4 chapters, Conclusions and References.

The introduction reveals the investigated problem, importance of the thesis and the object of research and describes the purpose and tasks of the paper, research methodology, scientific novelty, the practical significance of results examined in the paper and defended statements. The introduction ends in presenting the author’s publications on the subject of the defended dissertation, offering the material of made presentations in conferences and defining the structure of the dissertation.

Chapter 1 revises used literature. There is presented review of methods for processes integration in building engineering systems, advantages, disadvantages. At the end of the chapter, conclusions are drawn and the tasks for the dissertation are reconsidered. Chapter 2 presents methodology for processes integration in building engineering systems. Chapter 3 investigates the possibilities to integrate processes in ventilation as well as in other building engineering systems. Chapter 4 suggests the algorithm for integration of processes in mentioned systems.

6 articles focusing on the subject of the discussed dissertation are published: one article – in the journal quoted by ISI Web of Science data base, one article – in the journal quoted by ICONDA data base and four articles – in proceedings of international and national conferences.
