The variety of furniture arrangement inside apartment unit around jabodetabek area to improve COP_c

An exploration of wall split air conditioning (AC) unit working in some apartments around Jabodetabek is conveyed based on the variety of furniture layout. The type of furniture arrangement of the apartments is exclusively developed to investigate their influence to the cooling coefficient of performance (COP_c). The study was focused on the establishment of the flow pattern uniqueness depend of the furniture arrangement. Using computational fluid dynamics tool, several variables were exploited such as apartment location and furniture layout. It is obtained specific air flow pattern since every single room within operated wall split AC unit which is control the COP_c degrees. There are five furniture layout designs for every city therefore it is obtained twenty-five different airflow patterns which is influence the performance of AC unit. It is concluded the best furniture arrangement for all city where it could be operated within the lowest energy consumption of air conditioning. The effort to reduce the electricity energy consumption of air conditioning operation in the building industry is in line to the Indonesia government policy. The selection of furniture arrangement which is the best COP_c is the one method to realise the energy saving program. Besides the number of Indonesia apartment building is very excessive particularly in the big metropolises such as in Jabodetabek (Jakarta, Bogor, Depok, Tangerang and Bekasi) area.
