Abstract. This chapter introduces and discusses various exergy-related methods that can be used to better understand and improve heating, ventilating, air conditioning, and refrigeration (HVACR) processes, systems, and applications. Environmental impacts are also considered, as these should be considered while designing HVACR systems.
Air-conditions (AC) are among the most common energy consuming equipment in residential, administrative, commercial and industrial buildings in various countries specially those in tropical regions. About 60% of total electricity consumption is related to AC systems ( Habeebullah, 2007, UNEP, 2000 ).
