Modernization of the airfield multi-purpose air conditioning unit AMK-24/56-131 by applying an electric drive for special equipment

Abstract

The article presents the results of a study on the ways and possibilities of modernizing the mechanical drives of the equipment loop and cabin loop of the AMK-24/56-131 multi-purpose air conditioner by replacing them with an electric drive (ED) to improve operational characteristics. The selection of a technical solution for improving the design of the airport multi-purpose air conditioner (AMAC), including the calculation of the electric drive for the equipment loop and the cabin loop, was carried out using an analysis of the standard size range of electric machines suitable for replacing the power plant (PP) with an ED in the AMK-24/56-131, a differential evaluation method by comparing the indicators of the standard size range of electric machines with those of the reference model, as well as methods of analysis and synthesis. It is shown that the application of these methods for the calculation, design, manufacture, and operation of AMAC contributes to a significant increase in their reliability and technical readiness coefficient with minimal indicators of metal intensity and energy intensity, which is currently relevant. The practical significance of the obtained results lies in improving the operational characteristics of the AMAC AMK-24/56-131, specifically the transition to an electric drive for the AMAC loops to enhance the quality of their drive. The relevance lies in increasing the reliability indicators of the AMAC to ensure stable operation, trouble-free service, and improved economic efficiency. Achieving high reliability is possible by reducing the impact of load on the AMAC components and assemblies, improving design solutions, increasing the strength and wear resistance of parts, expanding diagnostic capabilities, conducting accelerated tests at all stages of development, and improving maintenance. The object of the study is the operation process of the drive system of the special equipment of the airport multi-purpose air conditioner. The subject of the study is the determination of technical solutions and design features of the electric drive of the AMAC special equipment. Purpose: to develop ways to modernize the drives of the equipment loop and cabin loop of the AMAC AMK-24/56-131 by replacing the power plants with an electric drive to improve operational characteristics.
