Design, simulation, and optimization of portable atmospheric water generator using vapor compression refrigeration system

Abstract

Abstract In this study, the conceptual design and optimization of a portable Atmospheric Water Generator that uses a vapor compression refrigeration system is investigated. The cooling system is needed to decrease the temperature of the ambient air to below its dewpoint. The cooling capacity of the vapor compression refrigeration system was 0.3 kW. The airflow velocity was then varied from 1.5 m/s to 5 m/s with an increment of 0.5 m/s. The diameter of the opening input feed air is 5.7 cm. The ambient air was assumed at 30 °C and 80% of relative humidity as the feed for the system. The results show that the maximum water production was 0.285 L/h which was produced by the air velocity at 2.5 m/s
