In air split-conditioners, the degree of their energy perfection must be determined based on the analysis of their exergy efficiency. In this article the innovative mathematical model developed by the authors for exergetic analysis of the work of air split-conditioners.
In the face of growing shortages and rising prices for fuel and energy resources, the problem of energy conservation and the use of alternative energy sources to solve the problem of reducing energy consumption for the Ukrainian economy become very important. Today, the use of air splitconditioner heat pumps in buildings' heating systems is becoming more common.
In the modern technologies related to energy transformation, namely in split-conditioners, an important place is occupied by apparatuses and processes, which energy perfection can be objectively evaluated only on the basis of analysis of their exergy efficiency. This allowed substantiating the actuality of the research task due to insufficient information on the effectiveness of the use of various refrigerants in split-conditioners.
