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

determining the temperature after passing trough
nozzles of press-granulator, which allows to take
into account heat loss through the exterior surface
The article presents the description of the models of catalytic combustion systems, bioreactor for anaerobic digestion of organic waste and the research stand developed by the authors, which are the elements of the experimental sample of catalytic systems for the production and transformation of energy and allow us to study features of functioning of the catalyst systems in the anaerobic treatment of organic waste
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
The article provides a description of existing catalytic burning units, the rationale for improving the technical solutions of components and parts, and the catalytic burning unit proposed by the authors with a circulating bed of filler
The article describes the new variants of design of infrared heaters with directional movement of the catalytic filler. We have explained in detail the principle of functioning of the devices and proposed to
use infrared heaters within the complex with special materials
The results of the optimization of the design and
technological parameters of a device for circular soil
tillage in forest cutovers have been obtained. The
description of the approaches to modeling of circular
soil tillage, optimization mathematical model of soil
tillage and obtained results are given in the article
During the study, the authors have solved the problem
of determining the minimum number of operations by
optimizing fillability of a claw-shearing device with
trees. Sufficient optimality conditions have been
obtained. The numerical method for solving the
optimization problem was developed. We have also
performed a numerical experiment
