Abstract

Abstract: As an archipelago country located around the equator line, Indonesia has a broad ambient temperature range of varying atmospheric conditions. This issue should be concerned with applying ISO 16358-1 to calculate Seasonal Energy Efficient Ratio (SEER) on cooling, or so-called the Cooling Seasonal Performance Factor (CSPF). The ISO 16358-1 recommend a set of bin temperature which can be used as the basis for calculating the CSPF. The research objectives are to compare the local ambient temperature of four cities in Indonesia (Jakarta, Bandung, Pontianak, and Palembang) with the ISO bin temperature. The normal distribution graph of temperature for every four cities in Indonesia shows a remarkable difference from the ISO bin temperature. Jakarta's most occurring temperature range is 25 – 30 °C, Bandung is 21 – 23 °C, Pontianak is 24 – 26 °C, and Palembang is 24 – 26 °C, annually. Those numbers were compared to the ISO, which has the most occurring temperature range around 24 - 28 °C. The result on CSPF calculation of AC unit sample in the range of 4, 000 – 17, 000 Btu/hr (both non-inverter and inverter) using Indonesia local bin temperature compared with the ISO bin temperature has an average range of 5.10%. It was concluded that Indonesia's local ambient temperature affects the CSPF value, especially on the AC inverter unit. On the other hand, the relatively small difference value of CSPF has an advantage in applying the ISO bin temperature for future Indonesia's energy conservation policy. It could lead to harmonizing with other South-East Asian (ASEAN) countries specifically, and another country also applying the ISO 16358-1, in general.
