Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This Article prepared the air-conditioning unit with supplying cooling air and warm water. The unit can work in three modes: only cooling air, only supplying warm water and cooling air with supplying warm water. The analysis results showed that the unit is more efficient than traditional systems, the maximum coefficient of performance (COP) is about 5.3 at cooling mode, the COP is 5.7 at mode of heating, and the COP is 4.5 at cooling and water heater mode
This research intends to obtain the discharge modeling for supporting water balance in the Konto Hulu sub-watershed-Indonesia, Based on the water balance, it can be investigated the water supply as well as the water demand. The methodology consist of discharge modeling by using F.J. Mock method that is based on rainfall data and some others one. The observed discharge data from the Automatic Water Level Recorder is used as the control of model validation. The potency of water supply is known from the dependable discharge due to the probability of 80% and the results is 22.41 m3/s that is proportional with 706.622 million m3 per-year, The water demand in incoming 25 years on scenario-1 (based on the growth rate) is 95.085 million m3 per-year, however on scenario-2 (based on the increasing estimation of domestic, non-domestic, and industry) is about 93.418 million m3 per-year. The result of water balance shows that the potency of water supply can fulfill the whole water demand or it shows the condition of water surplus reaches until 25% in 2017-2042
