09. Heat and Mass Transfer

Indonesia is a tropical country, which means it tends to receive sunlight evenly and has relatively high temperatures. This can be leveraged as an advantage in the utilization of solar energy but also poses a disadvantage in terms of high indoor temperatures due to thermal energy. The heat from thermal energy causes thermal discomfort in buildings, necessitating cooling systems that can increase electricity consumption. Therefore, energy conservation systems are an appropriate solution to address this issue. This research utilizes a Closed loop pulsating heat pipe (CLPHP) system with a binary working fluid of DI Water-Methanol for energy conservation in buildings. The Closed loop pulsating heat pipe operates on the principle of heat exchange in three sections: the evaporator, the adiabatic section, and the condenser. The evaporator is expected to absorb heat and move the working fluid as a heat transfer medium through the adiabatic section to the condenser to release heat. This research aims to determine the
