In this study an energy and exergy analysis of a Ceiling-type residential air conditioning (CTRAC) system operating under different climatic conditions have been investigated for provinces within the different geographic regions of Turkey. Primarily, the hourly cooling load capacities of a sample building \(\left( {{{\dot Q}_{evap}}} \right)\) during the months of April, May, June, July, August and September were determined. The hourly total heat gain of the sample building was determined using the Hourly analysis program (HAP). The Coefficient of performance (COP), exergy efficiency (η) and exergy destruction \(\left( {\dot E{x_{dest}}} \right)\) values for the whole system and for each component were obtained. The results showed that lower atmospheric temperature (T_atm) influenced the performance of the system and each of its components.
