Abstract
For arid and humid regions, atmospheric water condensation becomes the main water source when the water vapor in moist air is condensed effectively and efficiently. In this manuscript, an atmospheric water generator is designed and fabricated. The vapor compression system is used for cooling moist air. These cooling tubes are arranged in a rectangular shape in a vertical orientation such as pulsating heat pipes arrangement. The refrigerant R-22 flows inside the tubes. However, the condensation of moist air took place over these tubes’ surface which is coated by hydrophobic coating. This device was examined at various environmental conditions and condensing water from moist air. It has the maximum capacity to produce 6-L water in a day having a relative humidity of 70% and an atmospheric temperature of 32 ℃. However, the average power consumption in a day is 0.89 kWh/liter. This arrangement of the evaporator in vapor compression cooling has a high condensation coefficient as compared to other arrangements.
