Book Description

This book covers theoretical foundations of the Natural Gas (NG) installations and networks as a part of building logistic system, illustrated with digital examples. It describes the NG oxidation phenomena and appropriate energy converting devices used in the building’s energy centres and basic sizing principals of the related pipe networks. Further, it covers usage of NG devices including system for thermal comfort control, building ventilation, indoor air quality, visual comfort, food preparation and conservation, and hygiene maintenance system. A special attention is given to applications of the NG technological equipment, using gas-driven heat pumps, micro heat and power systems. Aimed at professionals and graduate students in the areas of HVAC, Plumbing, Architecture, Electricians, this book:

  • Presents complex, innovative and systematical approach to NG installations in buildings.
  • Reviews efficient and environmentally sustainable dementalization approach to building energy supply, using NGmHps v/s central energy supply systems.
  • Explains pre-designating calculations of the gas piping networks.
  • Illustrates structures, principals of operation and building project implementations of the modern GN energy converters and transformers as fuel cells (SOFC, MOFC, PEFC) and NG driven heat pumps.
  • Discusses calculation methods derived from professional case studies.

Biography

Alexander Dimitrov is a professional lecturer with 35 years of experience at four different universities. In addition to universities in Bulgaria, Dr. Dimitrov has lectured and studied at leading scientific laboratories and institutes in other countries, including the Institute of Mass and Heat exchange ”Likijov”, Byelorussian Academy of Sciences, Minsk; Lawrence Berkeley National Laboratory, Environmental Energy Technology Division, Indoor Environment Department; UNLV –ollege of Engineering, Center for Energy Research; Stanford University, California, Mechanical Department. Professor Dimitrov has conducted systematic research in energy efficiency, computer simulations of energy consumption in buildings, the distribution of air flow in an occupied space, modeling of heat transfer in building envelope, and leaks in the ducts of HVAC systems. Professor Dimitrov has defended two scientific degrees: Doctor of Philosophy (in 1980 - Ph.D.) and Doctor of Science (in 2012 - D.Sc.). With significant audit experience in the energy systems of buildings and their subsystems, he has developed an original method for evaluating the performance of the building envelope and energy labeling of buildings. He also has experience in the assessment of energy transfer through building envelope and ducts of HVAC systems. Professor Dimitrov's methodology has been applied in several projects with great success. He has developed a mathematical model for assessment of the environmental sustainability of buildings, named BG_LEED. He earned his Professor Degree in “Engineering Installations in the Buildings” with the dissertation “The building energy systems in the conditions of environmental sustainability” at European Polytechnical University in 2012. Subsequently, he has authored more than 100 scientific articles and 9 books, including 4 in English.
