About the frontal resistance to motion of the cylinder
According to conventional diagram of the flow past cylinder, dissipated power in the part of potential flow, formed by windward side of cylinder is calculated. Comparison of this power with the power, required to overcome the resistance to motion of the cylinder, shows that thin boundary layer in windward side of cylinder forms under Reynolds numbers exceeded 100.

Research of losses of a pressure on length hydraulically smooth cylindrical pipe is presented at low intensity of curling of a flow of a viscous incompressible liquid. Lowering of coefficient of a hydraulic friction in comparison with a forward flow in the field of values of integral parameter of curling is revealed. The extreme properties of the screw movements specifying a possibility of realization of advantages slightly of the twirled stream are considered. Analytical estimations and results of an experimental research are presented. It is specified in possibility of application of the received results in absorbing branch pipes of axial hydromachines.

Influence of the physicotechnical and geometrical characteristics of plastering covering on moisture conditions of AAC-blocks homogeneous walls
The article presents the technical analysis of the structure and physical characteristics influence of various plastering coverings on on moisture conditions of AAC-blocks homogeneous walls. The diagrams of partial (maximum and actual) pressure distributions of water steam along the thickness of the tested homogeneous outside walls are provided. Calculations and diagrams were done for both the coldest month of the year and the coldest five-days period, i.e. under the worst climate conditions. The essential patterns of the influence of plastering covering charactristics (thickness, density, vapor permiability coefficient) on humidity accumulation processes in walls are determined. Practical recommendations for finishing of AAC-blocks walls to protect them from excessive moistening can also be found in the research.

Technological optimization of temperature efficiency of heat recoverers with intremediate heat carrier
In the paper the padding investment costs and decrease of the consumption on a thermal energy are reviewed at salvaging a heat of exhausting air under the scheme with intermediate heat carrier in systems of mechanical ventilation. The nature of relation of the data of costs from a factor of temperature efficiency of heat recoverer is parsed. The expression for optimum temperature efficiency is offered by minimization of cumulative discounted costs during given computational term. The analysis of the obtained outcomes is given and the nature of their change at different parameters of an outside climate, and also operational price level on the equipment and fares on power supplies also is justified. The comparison of conclusions of the investigation to the data of the previous author’s researches is conducted. The presentation is illustrated graphically and by an example of numerical calculation.

Energy-saving technical solutions for local and central microclimate systems using heat pumps as local aggregates united into one water circuit
One of the priorities of energy savings is to implement energy saving measures in the work of heating systems, heating, ventilation and air conditioning systems based on heat pumps (HP). The dissertation considers using of a multizone central air-conditioning system with chilled beams for increase of power efficiency of a building was offered. In a transition period (the spring, autumn) in a building are observed both surplus of heat in one premises, and shortage of heat in others. At the expense of use low-temperature circuit and chilled beams of type "water-air" surpluses of heat are transferred in premises with shortages of heat and on the contrary. The given technology allows saving essentially thermal and electric energy in a transition period of year.

Efficiency evaluating of air conditioning system with air dehumidification section
The upward trend of energy resources cost, reducing OF resource reserves, yearly growing requirement of heat energy led to the need of careful selection of HVAC system and economic justification of this choice.
In this article on the example of indoor pool the most economically efficient variant of climatic parameters for high humidity areas has been selected. The calculation of operating, capital and reduced costs has been done. The reliability estimation and efficiency evaluating of the systems also have been done.

Mathematical modelling of hydraulic conditions of balancing and control of heating, cooling and dehumidification subsystem in ventilation and air conditioning systems
The goal of these investigations is modeling of processes and studying of influence of quantitative characteristics and parameters in heating and cooling subsystem of ventilation and air conditioning systems at balancing this subsystem by means of various balancing valves and control of three-running valve.
Balancing and management processes are considered on an example of the binding water air-heater of ventilation and air conditioning system. Besides, influence of various regime parameters on considered balancing characteristics is studied, as that: difference of pressure in a network of a heat supply, the pressure created by the pump, their parity, various water temperatures, the modes leading to self-oscillations.
Result of work is reception of balancing and adjusting characteristics of a considered subsystem in most general view under various working conditions and their further analysis.

The system approach to energy savings in engineering networks of buildings
Taking into consideration that there is not definite differentiation between definitions "economy of energy" and "energy saving", often the effect of energy effective technologies can be received only by reduction of air exchange, that is breach of sanitary and hygienic regulations. In the article the attempt to distinguish these definitions with using system approach is done.
In building branch absence of the system approach to building and city leads to serious system errors. For example, warming of building wallings using natural ventilation don't give real energy saving, but it leads to the air exchange decrease, therefore the given action raises risk of various diseases. In the article various system errors which can lead to acceptance of the erroneous decisions, influencing the sensitive initial data through air exchange reduction, are considered. A consequence of it are diseases of noninfectious character. To decrease quantity of system errors it is offered to use the system approach to these problems.
