High Density Highperformance Computing Systems Cooling

The paper deals with the cooling approaches and aims at using solutions for the energy efficient and economically viable high density computing system construction and usage. Power consumption of the standalone high density computing systems and supercomputing clusters with different types of cooling has been considered and their characteristics have been estimated. The influence on the overall budget of the system construction and exploitation for 5 years of life time has been analyzed.


Energy conservation is becoming increasingly more relevant for Ukraine and the world, and architectural education must meet one of the most significant challenges of our time. The article analyzes the existing laws and regulations of our country and points out to the lack of a number of national standards necessary for architectural design. It focuses on the problems of real design and ways to solve them within the framework of architectural training.

Архітектура багаторівневої системи управління енергоефективністю регіону

The list of problems that can be solved by multilevel system of energy efficiency of the region were determined. Requirements for the implementation of each system component were formulated. It was shown that the technological process control’s components should provide processing of intensive data streams in real time. Also components have to satisfy limitations on size, power consumption and cost.

Energy Efficiency of Refrigerating Ejector Systems for the Condensation of Oil Product Liquid Hydrocarbons

The oil processing enterprises are the largest consumers of fuel and energy resources, heat and electrical energy. Efficiency, rationality of their use in oil refining processes in many respects is defined by overall performance of processing equipment. Feature of processes for processing a hydrocarbon raw material is that technology processes are imperfect. One of the priority directions of increase in efficiency of energy saving of oil processing productions is the maximum use of recuperation of warmth and optimization of operating modes of technology installations.
