The objective of this study is to analyze all the energy used in the solar cooling system in Universitas Indonesia. This system uses three energies at the same time, namely, solar, gas and electricity energies, which are used to provide a required cooling capacity from the mechanical research center (MRC) building in Universitas Indonesia. The single-double-effect absorption chiller is the main component of the solar thermal cooling system to provide the chilled water that is circulated between the system and MRC building. In this system, heat from solar energy is absorbed by the evacuated tube solar collector and then transferred to the hot water that is used to generate vapor together with the gas at the absorption machine. On the other hand, electricity is mostly consumed by the pumps to circulate the hot, cooling and chilled water, also the working fluids inside the absorption machine. Finally, all the energies used to create a thermal comfort zone in the MRC building based on the Indonesia weathers are reported in this paper.
