Exergy Analysis of Air Conditioning (AC) System in Suite Room Santika Hotel Yogyakarta

Abstract

Air Conditioning are major contributors to energy consumption in-suite room Santika Hotel Yogyakarta. A suite room is a choice of rooms with the best facilities compared to other rooms, so comfort is one of the services that must be optimized. The ain is to determine the conduction heat load of various components in the room. Heat conduction load calculation includes heat load through the glass on the east 1253.18 BTU/hr, conduction heat load through the wall to the south 606.14 BTU/hr, solar radiation through glass 1268.48 BTU/hr, heat gain from people 1980 BTU/hr, electrical equipment/lights 2193 BTU/hr and heat gain from ventilation 13053.6 BTU/hr. The total amount of heat gain used in exergy analysis calculation with a value of 3053.16 BTU/hr.
