Abstract: Thermal comfort demand in modern buildings is provided by mostly usage central air conditioning and ventilation systems. In these applications, the comfort parameters of the structure are directly related to control of air velocity, blowing temperature, air quality and energy consumption. In these processes, reduction of energy consumption considering thermal comfort conditions and system management with energy efficiency in buildings should be evaluated together with the heat recovery potential in the air conditioning systems. In this study, the thermo-economic analyses of four different application including the heat recovery systems in the air conditioning systems, which was designed for an office building, were made. In these thermo-economic analyses, it is seen that up to 72% energy saving can be achieved with the heat recovery preference according to standard conditions. At the end of the study, system preference in a centralised air conditioning system based on air conditioning processes and its contribution to sustainable energy management were assessed.

Keywords: air conditioning unit; heat recovery; energy management; efficiency; sustainability.
