Summary: The microclimate of a pigsty is determined by the combination of
temperature, relative humidity, chemical and mechanical composition of
the air, which have a significant impact on animal productivity and must
be maintained within strict limits due to the physiological needs and
capabilities of animals. An appropriate ventilation system has been created
to ensure the removal of air from the pigsty. The purpose of the study is
to establish the dependence of the operating parameters of the automatic
ventilation system on the air quality in the pigsty, taking into account the
permissible concentrations of gases. The developed automatic ventilation
system for polluted air intake is located in the middle of the livestock
house under the ceiling and consists of a central air duct, to which air
intake pipes are connected. Air intake pipes are placed in the middle above
each pen where animals are kept. Intake dampers with servomechanisms,
temperature, humidity, and air quality sensors are installed at the inlet of
the air intake pipes. The outlet of the central air intake duct is connected
to the exhaust fan. Intake dampers with servomechanisms and sensors of
temperature, humidity, and air quality are connected to the control unit by
electrical wires. As a result of analytical studies of the automatic ventilation
system for polluted air intake from a pigsty, the conditions for its effective
operation have been mathematically substantiated. The developed technique
and the algorithm implemented based on the Mathematica software
package allows calculating the area of holes that form intake dampers
with servomechanisms in the air intake pipes. The distribution of velocities
in the air intake pipes and the distribution diagram of the area of holes
that form intake dampers with servomechanisms in the air intake pipes are
determined taking into account the design and technological parameters
of the ventilation system and the distribution of the gas concentration
(carbon dioxide, ammonia, and hydrogen sulphide) over the pens
