Development of the Life Cycle Extension Algorithm of the Air Conditioning Systems (ACS)

Abstract

Introduction. The scientific problem tackled by the authors is the need to analyse and evaluate the life cycle of the air conditioning systems (ACS) for developing an optimal technology of creating the favourable indoor climate, which enables people’s productive work and rest as well as the normal flow of the technological processes. The study aimed at investigating the life cycle of an ACS as a facility of the comfortable indoor climate provision within the urban mixeduse complexes.Materials and Methods. The authors' research is based on the methods of mathematical and system analysis used to find out the solution for extending the life cycle of the indoor climate provision facilities.Results. As a result of the research, the ACS main life cycle stages were distinguished, their relations to the respective operational parameters were determined, the formulas for calculating the criteria and nondimensional indicators of the indoor climate provision system’s operation assessment were proposed. Discussion and Conclusion. The carried out analysis on distinguishing the life cycle extension capacities allowed us to conclude that the ACS operational stage provides the best opportunities for selecting the optimal layout of the system functional units and the air conditioning technology. The formulas for calculating the criteria and their respective nondimensional indicators enabling the development of the recommendations and ways of extending the ACS life cycle have been determined and described.
