abstract: implementing a combined cooling, heating and power system(cchp) to cool, heat and produce electricity is growing rapidly due to its efficiency and low emissions. in this paper, using economic analysis, the size and operation detail of the required gas engine and the specific electricity, cooling and heating load curves for a one year operating period has been determined. the proposed ...

The paper analyzes the levels of magnetic flux density in apartment located above 10/0.4 kV distribution transformer station. During first field testing, it was concluded that case rated load transformers, increased values would occur apartment. main sources were busbars and cable lines connecting transformers 0.4 cabinets. For reason is proposed to apply measures reduce density, which are desc...

It used calculate and analyze energy-economic operational-technical indicators individual heating boilers, small centralized systems, hybrid systems solve this...

For several decades,Iranian cities are experiencing major and fast urban growth. At the top of them is Tehran, Iran’s capital city, with doubled population in 30years from approximately 6 to 12.5 million in 2016. Undoubtedly such a magnificent raise in population has increasedthe need for settlements and the city has to respond to it. Today, Tehran,is the center for such exogenous development w...

ment construction project network, Hyundai Engineering and Construction and Korea Advanced Institute of Science and Technology developed a caseand constraint-based project-planning expert system for an apartment domain. The system, FASTRAK-APT, is inspired by the use of previous cases by a human expert project planner for planning a new project and the modification of these cases by the project...
