The performance of combined cooling, heating and power (CCHP) systems is obviously dependent on the climate conditions. This paper presents an economic analysis of the CCHP generation systems for a typical building in five different atmospheric conditions. Total annual costs, savings and income are considered as important criteria to estimate the performance of CCHP systems for a hypothetical hotel building in five cities in Iran with different climates from the technical, environmental and economic features. The comparison results suggest that the CCHP system is generally appropriate for Tehran, where from the viewpoint of economic performance, obtains more benefit over other cities.
