Desain Alat Pengering Memanfaatkan Panas Buang Alat Pengkondisian Udara

Abstract

Air conditioning device is a machine made to stabilize the temperature and humidity of the air in a room. The potential for heat wasted from the condenser of the air conditioning device is still a waste that is exposed to the surrounding environment, and has not been utilized. Even though thermal energy is very potential and can be used for dryers. Drying is the process of lowering the moisture content of the test material so that water activity decreases. This study aims to obtain a dryer design utilizing condenser exhaust heat from an air conditioning device that can be utilized optimally, and to obtain the value of the hot air flow rate that comes out of the condenser of the air conditioning device. As well as to obtain the temperature distribution of each shelf in the drying chamber and obtain the drying rate of the test material on each shelf in the drying chamber. The method used in this study is to use experimental methods. This method is carried out by conducting experiments directly. Based on the temperature gains of hot air coming out of the condenser of the air conditioning device after arriving at the planum chamber, it shows that the exhaust heat generated by the condenser of the air conditioning device has the potential to be used to dry kratom leaves, corn seeds, and rice seeds. Because based on every test that has been carried out, the highest hot air temperature of condenser output ever achieved after arriving at the planum chamber is 54.30°C with RH = 19%, while the lowest condenser output hot air temperature achieved after arriving at the planum chamber is 47.00°C with RH = 30%. And the average hot air temperature produced by the condenser of the air conditioning device after arriving at the drying room ranges from 30.27°C to 42.93°C.
