Sem 2 Session 2014/2015THE ATMOSPHERIC WATER VAPOR

EXTRACTOR/HARVESTOR/COLLECTORThe atmospheric air always has water vapor present in it. This is part of the hydrologic cycle, where water evaporates from the seas and other water bodies, the vapor is carried by air into the upper atmosphere where it forms clouds which then condense into water as rain or snow. The total water vapor in the atmosphere is so large that it can meet all of human water needs.

An atmospheric water extractor is a device that extracts water from humid ambient air. Water vapor in the air is condensed by cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an atmospheric water extractor is designed to render the water potable. Atmospheric water extractor are useful where pure drinking water is difficult or impossible to obtain, because there is almost always a small amount of water in the air that can be extracted.

The rate of water production depends on the ambient temperature, humidity, the volume of air passing over the coil, and the machine's capacity to cool the coil. These systems reduce air temperature, which in turn reduces the air's capacity to carry water vapor.

Task

1. Students are required to form a group comprises of maximum 5 students (and minimum 3 students).

2. Each group is required to design an atmospheric water vapor extractor for public purposes at about 100 200 litres capacity by using the method of condensation.3. There is no restriction on the dimension and the chosen equipment/facilities. However, all the specification/information of its must be attached together in your report.

4. Each group then needs to write a full report and the report should be detail and attractive, complete with detail design, drawings, calculations and figures of your proposed system. The report must be also included the introduction, discussion and conclusion.5. Besides the equipments information/specification, the report must also be included the references (information gathered), the minutes of meeting, work delegation/milestone and group member assessment of every group members for soft skills/ generic skills assessment. The group member assessment form is as per attached.

6. All reports must be submitted by week 12.
