We have presented technical solutions of an energy
supplying complex of apiary based on a solar plant,
which ensure its functioning in the winter. Various
aspects of the influence of the snow cover on the
functioning of the complex are considered in the
article. The favorable effect of the snow cover includes
increasing the diffuse insolation, improving the
thermal insulation of the building for placement of
bees, which protects bee families from fluctuating
external temperature. The negative effect of the snow
cover includes adherence of snow to the receiving
surfaces of solar energy converters, which can lead to
decreasing the efficiency of using of photovoltaic
modules and solar collectors. Both active and passive
methods of combating snow sticking are suggested in
article. Passive methods include installation of solar
energy converters at an angle close to 90°, as well as
their placement on the windward side. The simulation
of the functioning of the complex based on a solar
plant was conducted for climatic conditions of the
Republic of Mari El (the time interval – from 14
October to 14 April, a photovoltaic module area – 1,3
m
2
with installation angles of 72˚ and 88˚). Because of
the simulation, we obtained graphs of the changing the
power of the photovoltaic module. Active methods
include air injection onto the receiving surfaces of
solar energy converters and using of heating elements
The article describes the modeling process of the
heating system operation of a livestock-breeding
complex. It presents graphs reflecting the influence of
technological parameters of heat supply system of
cattle-breeding complex with a catalytic combustion
device on the parameters of energy efficiency of the
system and the parameters characterizing the stability
of the temperature conditions in the livestock sector
The article presents investigations of engine oil with
the addition of special additives and reactions of the
composition in the process of friction on the metal
surface, simulating the boundary and hydrodynamic
friction
The article presents the mathematical models of
technological modes of crushing, drying and
pressing in the production of pellets from wood raw
material with a high degree of rot
In the article, we present a simulation mathematical
model of an energy-supplying complex of apiary
based on hybrid solar plant that establishes the
relationship between the design and the operating
parameters of the complex with when having
conducive winter maintenance of bees. Modeling
methodology involves the selection into a
mathematical model of multiple levels: level of
processes, that directly related with changing of
climate parameters inside the hive depending on
external factors, level of processes of functioning of
the individual components in the complex, which are
not directly connected with the processes of changing
of climate parameters inside the hive, however, are
necessary to ensure favorable conditions for wintering
of bees. We have conducted the simulation of the
complex based on hybrid solar plant for conditions:
the location of apiary in the Republic of Mari El
(building for placement of bees for 250 bee colonies,
the number of photovoltaic modules – 10, wind power
plant area – 18 m2
, the capacity of the battery – 50
A·h, the heat accumulator capacity – 3 m3
, the time
interval – from 14 October to 14 April). As a result of
simulation obtained graphs of the changing the
thermal battery coolant temperature, the voltage at the
battery terminals, the power wind turbine and PV
modules, the electrical energy consumption
The article presents the mathematical model for
determining the temperature after passing trough
nozzles of press-granulator, which allows to take
into account heat loss through the exterior surface
The purpose of this research is to receive mathematical
model of natural drying of the whole trees in bunches
in a cutting area based on experimental data. The field
research of natural drying from March to October 2015
of the whole trees of pine and birch of different
diameter laid definitely in bunches in a cutting area
was conducted for this purpose. The mathematical
model describing change of moisture content in wood
in the course of natural drying in bunches in a cutting
area was as a result developed. The received equation
of regression defines dependence of average humidity
of wood in a bunch from diameter of wood, quantity of
a liquid atmospheric precipitation, relative humidity
and temperature of air, average speed of the movement
of the air blowing in bunch of trees, duration of natural
drying. The developed mathematical model allows
predicting change of moisture content of wood in the
course of natural drying with a margin error less than
5%. Humidity of wood in the course of natural drying
from March to October was on average reduced from
52% to 27%. Besides, in article the technology of
logging of fuel wood on an energy forest is offered.
The technology of stacking of trees in bunches at
logging of the fuel wood which is grown up in forest
plantations is offered. The results of the research can
be used for increase of production efficiency of fuel
wood
