Abstract


Water is a fundamental human need that is very important and must be met in everyday life. During the dry season, a number of areas in Indonesia encounter droughts which result in scarcity and difficulty in obtaining clean water. Therefore, research on air-water harvester needs to be carried out to determine the performance of this machine and in order to increase its water production. This research examines the effect of evaporator pressure on the mass of water production. The evaporator pressures varied were 30 psi, 40 psi and 50 psi. The refrigerant used was R134a for environmental friendly purposes. The specification of the compressor used was a compressor with a power of 1/2 PK. The results show that the highest water production mass was obtained at a pressure variation of 30 psi with an average mass of 0.4384 kg. The lowest water mass of 0.1773 kg was attained at a pressure variation of 50 psi. The highest COP of 25.29 was obtained at a pressure variation of 30 psi and the lowest COP was 10.84 at a pressure variation of 40 psi.
