The article presents a mathematical model of the
reliability of the flexible robotic manipulator, which
establishes the relationship between the design
parameters of the individual elements of the flexible
section of the handling robot and the indicators of
reliability section
We have presented the program, methodology and the results of the experimental research of the functioning of a complex for climate control of beehives
In the article, we have presented the variant of the heat accumulator based on phase transition with a screw heat exchanger, designed to meet the demands of heat supplying systems in thermal energy storage
This article presents the variant of the implementation of a system for heating supplying of buildings for placement of bees based on catalytic devices for burning biogenic fuels, as well as it offers a general idealized model of quantifying the effectiveness of technical-technological system
We have presented a methodology for the optimization of technical parameters of the complex based on a solar system combined with a wind generator according to the criteria of efficiency and consumption of materials
The article assesses the energy efficiency of the technical and technological systems based on catalytic combustion systems nutrient liquid and gaseous fuels for heating various production facilities and agro-forestry systems
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
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
We have presented a simulation mathematical model of a complex for climate control of beehives that establishes the relationship between the performance parameters of the complex and efficiency parameters with a condition of descent winter maintenance of bees
