Automated Microclimate Regulation in Agricultural Facilities Using the Air Curtain System

Abstract

Creating and maintaining the microclimate in livestock buildings is associated with numerous engineering and technical challenges. Together with adequate feeding, the microclimate determines the health, reproductive ability, and production potential of the animals (obtaining a maximum amount of high-quality products). One of the deciding steps in improving the parameters of microclimate, i.e., temperature and humidity in agricultural facilities, particularly in livestock buildings, is to develop reliable and highly efficient air curtains in the vestibules. The objective of the manuscript is to investigate the parameters of the microclimate in livestock buildings using the air curtain, supported by automation and ICT technologies for rational operating modes. The presented theoretical and experimental studies on improving the microclimate parameters in livestock buildings were carried out using an innovative air curtain system. Its power is calculated based on the dimensions of the room, and the flow rate of warm air near the floor level is three times lower than at the installation site. The use of air curtains reduces consumption of thermal energy needed to maintain an optimal microclimate for livestock by 10–15%. Furthermore, the use of an automated digital control system maintains an optimal microclimate in the building. The developed energy-saving system for creating an optimal micro-climate in livestock buildings using air curtains was tested in a pigsty of the Research and Training Farm “Vorzel” of the National University of Life and Environmental Sciences of Ukraine, located in the Kiev region. The developed automated microclimate system using air curtains significantly improves the microclimate parameters and significantly reduces power consumption. The system can be further developed by adding remote control based on the Internet of Things (IoT) technology.

Modeling of Diesel Engine Fuel Systems Reliability When Operating on Biofuels

“…Similar shortcomings can be traced in [36] of automated control of the temperature characteristics of systems, and [37] improved the quality of the operating parameters of the environmental performance of engines. However, such approaches complicated the design and increase the cost of equipment operation.…”

“…The reliability of the unit depends on the reliability of each of the subsystems as well as on the use of various types of fuel (finely dispersed [36][37][38]), in particular, biofuel and the adaptation of the fuel system to it. These subsystems can be both in good and faulty condition.…”

The Grain Cleaning Production Lines’ Energysaving Operation Modes of Electromechanical Systems

“…At the same time, it was established (Postnikova, 2011) that the most informative indicator for determining energy-saving modes of operation is the specific consumption of electrical energy for the grain cleaning process. The ZAV-25 unit was studied in terms of the influence of its operating modes on its power demand using MEP (Nazar'jan et al, 2012;Kiktev et al, 2021).…”

Robotic Platform for Horticulture: Assessment Methodology and Increasing the Level of Autonomy

“…In addition, it is necessary to predict the risks of investors in business projects associated with the introduction of robotics in agriculture, according to the "European Green Deal" in connection with possible threats in the food market (Faichuk, O.; Voliak, L.; Hutsol, T. et al) [41] and conduct ecological and economic justification of the introduction of robotic technologies in horticulture. In the future, it is planned to expand the use of the developed autonomous robots to other branches of agriculture, including the automation of production processes in livestock buildings [42], in greenhouse [43], when planting and unloading the energy willow cuttings [44] et al…”
